Returns: A Modest But Happy Summary of The Year’s Storm Chases

Wow! More than a year has passed since I've posted in this blog. So much has happened, some of which amounts to a veritable sea change in my life. But I'm not going to get into that here. Relevant for is this: the site's URLs, which acquired an unwarranted and unwanted prefix when I was forced to switch from my superb but now defunct former webhost to Bluehost, are now fixed, and this blog is properly searchable and functional again.* Already, in just a couple days, I've seen three sales of my book The Giant Steps Scratchpad, and hopefully this site can once again gain some traction as both a jazz saxophone resource and a chronicle of my obsession with storm chasing.

As the dust began to settle from a painful but beneficial transition, I found myself with the wherewithal to finally chase a bit more productively and independently than I have in a long time. It felt wonderful—wonderful!—to hit the Great Plains again in a vehicle that is trustworthy, economical, and comfortable for driving long distances. Kansas, Nebraska, South Dakota—hello, old friends. It was so good to see you again at last, such a gift to drive your highways and take in your far-reaching landscapes . . . and yes, to exult in your storms, your wild convection that transforms your skies into battlegrounds of formidable beauty.

It is a long drive from Michigan to tornado alley, eight hundred miles or more just to get to the front door. Ironically, I could have spared myself most of my first trip. It landed me in Wichita overnight, then on to chase the next day in southwest Kansas and northeastward almost to Salina. No tornadoes, though. They were there, all right, but I was out of position and uninclined to punch through a bunch of high-precip, megahail crud along the warm front in order to intercept potent-looking (on the radar) but low-visibility mesocyclones. Two days later, though, on May 20 in northwest Indiana on my way back home, the warm front was exactly the place to be, and I filmed a small but beautiful tornado south of Wolcott. It was my one confirmed tornado of the year.

A few weeks later I hit the northern plains with my friend Jim Daniels, a retired meteorologist from Grand Junction, Colorado. It was his first chase, and for me, one of the blessings, besides the good fellowship and opportunity to build our new friendship, was introducing someone to chasing who already had his conceptual toolkit assembled. No need to explain how a thunderstorm works or how to interpret radar—Jim's a pro; I just handed him my laptop, let him explore the tools, and we were ready to rumble.

Except—no tornadoes.

Then came August and a shot at severe weather right here in Michigan. I tagged along with a slow-moving, cyclic, lowtop supercell with classic features through the western thumb area of the state. It was nicely positioned as tail-end Charlie, sucking in the good energy unimpeded. A little more instability and it could have been a bruiser. As it was, it cycled down to the point where I thought it was toast, just a green blob on GR3, at which point, faced with a long drive home, I gave up the chase. Naturally the green blob powered back up and then spun up a weak twister ten or fifteen minutes later.

I didn't mind missing the tornado. Well, not much. I had chased about fifty miles from Chesaning to south of Mayville, about two and a quarter hours, and gotten plenty of show for my money—rapidly rotating wall clouds, a funnel or two, and some really sweet structure of the kind you rarely see in Michigan. Then on the way back, as a cold front swept in, the sunset sky was spectacular.

Waterspout season has also come and gone, and I hit the lakeshore a number of times. One of those times was fruitful, and I captured some images of a couple picturesque waterspouts out at Holland Beach. They were all the more interesting because they occurred southwest of a clearly defined mesocyclone. But I'll save that and a pic or two for a different post. It deserves a more detailed account, don't you agree? is about jazz saxophone and improvisation as well as storm chasing. So if jazz is your preferred topic, stay tuned. It'll be comin' at ya. Got a few patterns and licks to throw at you that I think you'll enjoy.

That's all for now. is back in the race.


* The one exception is the photo gallery. Photos in individual posts work fine, but the links on the photos page don't work.

Also, formatting is messed up in the text of a lot of older posts. So I still have some issues to work through with BlueHost. I'll probably have to pay to get the image gallery working right again; hopefully not so with the formatting stuff.

An Interview with Wade Szilagyi, Director of the International Centre for Waterspout Research

It has been far too long since I've posted in this blog. Since my last post on my first-ever Lake Michigan waterspout intercept--and an amazing intercept it was, at that--waterspout season has come and gone, and Hurricane Sandy has wreaked damage of historical proportions on New York City and the New Jersey coastline. But, caught up in editing projects, I haven't had much energy for writing my own stuff. I have had a couple things up my sleeve, though, both musical and meteorological. This interview is one of them, and I think you will find it worth the wait. It features Wade Szilagyi, founder and director of the International Centre for Waterspout Research (ICWR) and developer of the Waterspout Nomogram and the Szilagyi Waterspout Index (SWI). Wade is not only at the cutting edge of waterspout research and forecasting, but he drives and defines much of it. I'm pleased and honored to have him as my guest. Born in 1963 in Toronto, Ontario, Wade moved to Whitby in 1973, where he currently resides. He graduated in 1987 from the University of Toronto with a degree in atmospheric physics and was hired by the Canadian federal government as a meteorologist that same year. He worked as an operational meteorologist until 2001, when he moved into the National Service Operations Division as a national coordinator for program development and standards. Wade has published several articles and research papers on the topic of waterspouts and forecasting. He has also appeared on various media outlets discussing the topic of waterspouts, including interviews on The Weather Channel and Interlochen Public Radio and a writeup in Wade has two sons who are now in university. One is taking criminology and the other, mechanical engineering. Their father says, wryly, "I couldn’t convince them to go into weather!" Wade likes to stay active. "I am very big on health and fitness," he says. "I love to dance, bike, kayak, and power walk. I am a big believer in self-improvement and strive to be strong in mind, body, and soul." With that background on Wade the person, I now present to you Wade the waterspout researcher. I think you will find he has some fascinating things to say. Question: Let’s start with the question that I’m sure is burning in everyone’s curiosity: How do you pronounce your last name? Give us the phonetic spelling. Wade: Sa-la-gee Q: Please tell us how you first became interested in meteorology. W: It all started in grade eight science class. We were doing a unit on weather; however, the passion didn’t hit me until the end of the chapter. One of the chapter questions was to construct a weather observation table. My table consisted of weather parameters such as temperature, relative humidity, cloud cover, wind velocity, etc. I took weather readings and entered them in the table twice a day. I thought I would do this for a week; little did I know that it would last for five years! Much came from those tables: graphs were produced, trends analyzed, and a climatology for my home town was initiated. This finally culminated with the entry of my project in the science fair in grade 13, for which I won second prize. I still remember teachers bringing their students past the displays. One teacher didn’t believe that I was dedicated enough to take weather readings twice a day every day for five years. He accused me of making the readings up. In my defense, I told him to talk to my teacher, who had known me for several years. Q: You serve as director for the International Centre for Waterspout Research as well as with the Weather Office of Environment Canada. Please tell me a bit about your training and experience as a meteorologist. W: The training as a meteorologist begins at university. There are different routes one can take in order to satisfy the requirements to become a federal government meteorologist. One must have a BSC degree in meteorology, atmospheric physics, or a combination of math and physics. I chose the atmospheric physics route. After graduating, I was hired by the federal government and took a mandatory year-long operational forecast training program. This is where one learns how to forecast the weather. After graduating, I was sent to the Toronto Weather Centre, where I remained for ten years. At this office I produced various forecast products such as aviation, public, marine, fire weather, and specialized products. Eleven years ago, I left the Weather Centre and went to the National Services Division, where I am a program manager for weather standards. Q: One thing I immediately picked up on in talking with you is that you are utterly enamored with waterspouts! Clearly your knowledge of them has been fueled by genuine passion and fascination. When and how did waterspouts first capture your interest, and what has been your path as a foremost waterspout research scientist? Who has been influential along the way? W: As with many discoveries in life, my interest in waterspouts came about by accident. Originally, I was investigating the phenomenon known as “arctic sea smoke.” This forms over open bodies of water at very cold air temperatures. Arctic sea smoke was a problem at one of our airports on Georgian Bay; it would frequently reduce the visibility near the runway. I started looking into how to forecast arctic sea smoke. On days when arctic sea smoke occurred, I went down to Lake Ontario to gather data. By accident, I noticed several transient swirls forming in the sea smoke. These are called steam devils, and I quickly became interested in them. On one occasion I saw a huge steam devil. I called it a “winter waterspout.” It was at this point that my fascination with waterspouts began. At the time, little was done in the way of waterspout forecasting. Weather centers would issue a Special Marine Warning (U.S.) or a Waterspout Advisory (Canada) only after a waterspout was sighted. On one midnight shift, I said to myself, “We are forecasters. We should be able to predict waterspouts.” I began gathering meteorological data during waterspout events in order to develop a forecast technique. A couple of years later, the first version of the technique, the Szilagyi Waterspout Nomogram, was developed and used at the Weather Center in Toronto. Over the years, as more data was gathered, the Nomogram was improved. Recently, I developed the Szilagyi Waterspout Index (SWI), which is based on the Nomogram. From the SWI, and with the help of my colleague, my dream of developing the world’s first operational waterspout forecast model was achieved during the summer of 2012. Waterspouts can now be predicted with confidence up to two days in advance! The Nomogram and SWI are now used at weather centers around the Great Lakes and on both coasts of North America, and they are now being investigated in other parts of the world, especially Europe. During this period, I have written several articles and research papers and have given media interviews. I also formed the International Centre for Waterspout Research (ICWR) in 2008, which is a non-governmental organization comprised of research scientists, meteorologists, storm chasers, etc. from around the world who are interested in the field of waterspouts. Regarding who has been influential along my waterspout research path, I would have to say Dr. Joseph Golden. Dr. Golden is considered the “father of waterspouts.” He spent most of his career studying waterspouts and how they form. I was honored to have met Dr. Golden at the Great Lakes Operational Meteorology Workshop in Traverse City, Michigan, back in the 1990s. Frank Kieltyka, a meteorologist from the Cleveland Weather Office who conducted waterspout studies over Lake Erie, was also influential in the early days. Internationally, Dr. Alexander Keul, from the Vienna University of Technology, and Michalis Sioutas, from Meteorological Application Centre in Greece, inspired me to work on joint international research projects and to establish the International Centre for Waterspout Research. Q: I first came across your name as the author of a brief 2009 paper titled A Waterspout Forecasting Technique. In it, you described four types of waterspouts—thunderstorm-related, upper low, land breeze, and winter—and offered three significant parameters for forecasting them. Presumably, thunderstorm-related waterspouts evolve through processes familiar to storm chasers. But the remaining three are less familiar. Would you briefly describe the conditions that produce them and what distinguishes them from each other? Do any of them have a land-based equivalent? W: As a correction to the article, “thunderstorm-related” should be “severe weather.” Severe-weather-type waterspouts, like tornadoes over land, are associated with mesocyclones. The other three types of waterspouts (upper low, land breeze, and winter) are categorized as fair-weather-type waterspouts. These form in a different manner than the severe-weather-type waterspouts. There are no mesocyclones associated with fair-weather-type waterspouts. In all three cases, circulation with fair-weather-type waterspouts starts at the surface of the water. As air rapidly moves upwards under the cloud, the circulation gets stretched upwards and forms a waterspout. What distinguishes the three fair-weather types is the weather pattern in which they form. Upper low waterspouts form under unstable conditions associated with what meteorologists call upper lows—large areas of cool, rotating air. Upper low waterspouts form any time of the day or night. Land breeze waterspouts form along convergent lines called land breezes. Land breezes form overnight under light wind conditions as warm air rises over the water and is replaced by cooler air from the surrounding land. This cooler air converges along a line over the water, and it is along this line of converging air that rotation is initiated and waterspouts form. Land breezes last until early afternoon, at which time the waterspouts dissipate. Winter waterspouts form when it is very cold and windy. This results in extremely unstable conditions over the water. However, winter waterspouts are rarely observed because lake effect snow obscures their presence. The land-based equivalent of the three fair-weather-type waterspouts is a phenomenon known as the landspout. Landspouts form in a similar way as fair-weather-type waterspouts. Q: You encapsulated the three chief parameters for forecasting waterspouts in the Szilagyi Waterspout Nomogram, which was the precursor to the Szilagyi Waterspout Index (SWI) and the ensuing colorized forecast maps for Great Lakes waterspouts. Those appear to be the first practical tools ever devised for forecasting spouts. Starting with the Nomogram, would you tell us how you developed them and exactly what they are? What improvements do you anticipate for the forecast maps? W: Back in 1994, I started investigating what meteorological parameters correlated well during waterspout events. I wanted these parameters to be easy to calculate for forecasters. Three parameters satisfied these conditions of good correlation and easy use.* I then plotted these points and noticed that they formed a concentrated cluster on the graph. I enclosed the cluster with two lines. These lines are called the waterspout threshold lines. If a calculated point falls within them, waterspouts are likely. Outside the lines, waterspouts are not likely. This is what constitutes the Nomogram. The Szilagyi Waterspout Index (SWI) is derived directly from the Nomogram. The purpose is to produce an index that can be used in computer algorithms to produce forecast maps of waterspout potential. The SWI ranges from -10 to +10. Waterspouts are likely for SWI ≥ 0. The new Experimental Waterspout Forecast System (EWFS) produces forecast values of SWI. Improvements to the forecast maps produced by the EWFS are planned. These improvements include a higher model resolution, simplification of the display, and most importantly, the incorporation of surface convergence. Surface convergence is essential for waterspout formation. Q: I understand that waterspout formation has five stages. Could you describe them? In a phone conversation, you mentioned to me that the presence of even a small funnel cloud means that a waterspout is already in progress, with circulation between the water surface and cloud base fully established. Most storm chasers are careful to distinguish between a funnel cloud and a tornado; they define a tornado by either the condensation funnel making full contact with the ground or else with visible rotation at ground level, typically verified by whirling dust or debris. How do you view this approach based on your experience with waterspouts? W: Dr. Joseph Golden was the first to identify the five stages of a waterspout. These are:

1. Dark spot. A prominent circular, light-colored disk appears on the surface of the water, surrounded by a larger dark area of indeterminate shape and with diffused edges.

2. Spiral pattern. A pattern of light and dark-colored surface bands spiraling out from the dark spot which develops on the water surface.

3.Spray ring. A dense swirling ring of water spray appears around the dark spot with what appears to be an eye similar to that seen in hurricanes.

4. Mature vortex. The waterspout, now visible from water surface to the overhead cloud, achieves maximum organization and intensity. Its funnel often appears hollow, with a surrounding shell of turbulent condensate. The spray vortex can rise to a height of several hundred feet or more and often creates a visible wake and an associated wave train as it moves.

5. Decay. The funnel and spray vortex begin to dissipate as the inflow of warm air into the vortex weakens.

Regarding reporting either a waterspout or funnel cloud, the same procedure should be followed as with observations over the land. Evidence of a spray ring, or a fully condensed funnel reaching the surface of the water, should be visible before reporting it as a waterspout. If there is no spray ring visible because it is too far away to be viewed, and if the condensation funnel appears incomplete, then it should be called a funnel cloud. Q: This year has been a record-breaker for waterspouts, bolstered by such landmark events as the September 21-24 Great Lakes outbreak. What has the ICWR gained, and what do you expect it to get, from this year? In your organization’s research overall, have you made any discoveries that have surprised you? W: This year’s record-breaking waterspout numbers have resulted in tremendous media attention for the ICWR (e.g. The Weather Channel). This media attention has resulted in more individuals submitting waterspout reports on our website, which we display.These reports are also used to update and improve the nomogram. A discovery that has surprised us at the ICWR is that the nomogram can be applied in other areas of the world, in particular over European waters. These observations were confirmed in a recent research paper. Q: Speaking of the ICWR, how long has it been in existence? What led to its formation, and what is the story of its growth? What are some of its significant achievement? What are some things you’d like to see it accomplish within, say, the next five years, and who besides yourself are the players? W: Founded in 2008 by me and two European colleagues, the ICWR is an independent non-governmental organization comprised of individuals from around the world who are interested in the field of waterspouts from a research, operational, and safety perspective. Originally conceived as a forum for researchers and meteorologists, the ICWR has now expanded interest and contribution from storm chasers, the media, marine and aviation communities, and from private individuals. The goals of the ICWR are as follows:
    • Foster the advancement of waterspout research and forecasting. • Provide an international forum for the exchange of information among researchers and meteorologists. • Facilitate the reporting of waterspouts from around the world from storm chasers and other interested individuals. • Promote, educate, and communicate to academic institutions, the media, marine and aviation communities, and private individuals.
Some of the achievements of the ICWR have been to jointly produce waterspout research papers. Another achievement has been the increase in public awareness of waterspouts around the world. Features on the ICWR web site called the “Live Waterspout Watch”, as well as the ICWR Facebook page have helped facilitate this public awareness. Some projects that are currently being undertaken, and which I hope will be completed in the next five years, are the Global Waterspout Forecast System (GWFS), Global Waterspout Database (GWD), and Global Waterspout Watch Network (GWWN). The GWFS will produce waterspout potential maps for the entire globe. The GWD is a database containing waterspout events from around the world. The GWWN is a global network of waterspout spotters. The ICWR is comprised of a director (me), as well as an executive committee. The executive committee has two representatives: Dr. Alexander Keul, from Salzburg University; and Michalis Siatous, meteorologist with the Greek Weather Service. The ICWR is also represented by a growing number of storm chasers, meteorologists, and research scientists. Q: Are there any ways that storm chasers, weather observers, and other interested parties can participate in or otherwise assist the work of ICWR? W: Yes. Storm chasers and weather observers can contact the ICWR and become part of the GWWN. Researchers and meteorologists can collaborate with the ICWR to produce joint research papers or develop forecast models. Q: How many waterspout incidents have you personally witnessed? Are there any that stand out as particularly memorable for you? W:I have seen waterspouts on five separate occasions. The most memorable one was the first time I saw them. I rented a cottage for a few days on the north shore of Lake Erie. The weather was warm and the hope of seeing any waterspouts diminished with each passing day. On the last day of the vacation, I stopped thinking about waterspouts. That morning the weather was cool. I went out onto the beach with my glass of orange juice and was looking around the sand. I looked up over the water, and to my amazement I saw a family of three waterspouts in a row! My jaw and the glass dropped. I ran into the cottage yelling, “Waterspouts!” My wife told me that I was like a kid in a candy store. I grabbed my video camera, and for the next fifty minutes I filmed several waterspouts forming and dissipating. Q: When you’re not researching waterspouts, what do you like to do? Got any hobbies that keep you occupied when the spouts aren’t spinning? W: Hey, waterspout research is my hobby! My other hobbies are archeology and treasure hunting, which I have been doing for the last twenty-six years. I have found several artifacts that have added to the knowledge of the history of my town. These artifacts go on display to the public at various events. I am also planning on creating a virtual museum. I should point out that one of my greatest dreams is treasure hunting on the beach while looking up and seeing a waterspout! _______________________ * The three parameters are as follows: (1) The difference between water temperature and 850 mb temperature; (2) the depth of convective clouds; and (3) the 850 mb wind speed, which must be less than 40 knots. For further information, Szilagyi refers readers to his article on waterspout forecasting.

Great Lakes Waterspout Season Is at Hand

Now is the time of year when waterspouts start putting in an appearance on the Great Lakes. I had largely forgotten about spouts until a few days ago when my friend and fellow weather weenie Mike Kovalchick mentioned them in an email. Bing! A light blinked on in my head: That's right! Waterspouts! I've never seen a waterspout. But then, until last year about this time with my buddy Kurt Hulst, I'd never made a point of going out after them. Kurt and I busted that day, but maybe this year I'll get lucky, provided I increase my chances by taking more opportunities to chase spouts. I have zero experience forecasting waterspouts. Thankfully, there's a snappy little graph called the Waterspout Nomogram that simplifies the process. Developed by Wade Szilagyi of the Meteorological Service of Canada, the Waterspout Nomogram provides a quick visual aid for determining when certain critical parameters are in place for four different classifications of waterspout: tornadic, upper low, land breeze, and winter. The tornadic variety is self-explanatory, and any storm chaser with some experience making his or her own forecasts should have a good feel for when that kind of waterspout is likely. Mike favors the 500 mb cold-core, closed low setup, which to my thinking may be a variant of the first in producing low-top supercells. The remaining two, land breeze and winter, seem to involve different dynamics. For all the waterspout categories, one of the constraints is that for spouts to occur, winds at 850 mbs have to be less than 40 knots, something I find particularly interesting in the case of supercell-based waterspouts. In any event, I'm hoping that this year is my year to finally witness a spout or two. Michigan chasers and weather weenies, it's time to pay attention to the marine forecasts. The "second season" can include action right along the lakeshore even when nothing's popping anywhere else. Make sure you bring your shotgun just in case a waterspout gets too close for comfort (written with a wink and a grin).

Breaking a Waterspout with a Gunshot?

While doing a bit of Googling on waterspouts, I came across an article in eHow that made me do a double-take, titled "How to Break a Waterspout with a Gunshot." My first response was to wonder whether the writer was referring to an old marine practice that I dimly remember reading about of trying to dissolve waterspouts with cannon fire. But no, the writer doesn't require that you use a cannon. All you need is a gun, he assures you, preferably one with "the blast strength of a shotgun or better." Here's a link to the article. And since it's a short piece and I'm leery of broken links, I'm going to also quote it here for you in its entirety.


  • Step 1: Assess the strength of the waterspout. Waterspouts are dangerous and require extreme caution, especially if you are going to approach one. You need to assess if getting close to the waterspout is feasible and safe. One good way of assessing the strength of a waterspout is to look at the clouds above it. Regular cumulus parent clouds usually produce weak waterspouts, while supercells produce stronger variants.
  • Step 2: Approach the waterspout. For the sake of breaking the waterspout with a gunshot, the closer you get to the waterspout the better. For the sake of your safety though, distance is preferable. This means that you need to get as close as you can get to the waterspout without jeopardizing your safety or the safety of your vessel and crew.
  • Step 3: Ready your weapon. A gun with the blast strength of a shotgun or better is required to break the waterspout. Most cases of successful use of a gunshot to break a waterspout occurred with a shotgun. So if you have a shotgun on board load it and get ready to fire.
  • Step 4: Fire multiple times. The more times you hit the waterspout the better your chances of breaking it. Your goal is to disturb the atmospheric dynamic that causes and sustains the waterspout with the force of the shotgun blasts. So, the more chaos you add to the waterspout the greater the chances that you can disturb the equilibrium of forces that produce the weather phenomenon.
Hmmm...sounds reasonable. Anyone care to give it a try? Let me know--I'll lend you my 12 gauge. On second thought, no I won't. Chances are that's the last I'd see of it. I wonder where this person has gotten his or her information, and what actual research--versus anecdotal evidence and pure speculation--is available to back it up? Even the weakest waterspout involves vast scales of motion that extend upward for thousands of feet and aren't likely to be be impressed by twinky little shotgun pellets passing through them. I've seen a video of an airplane flying through a fair-weather waterspout, and the spout didn't so much as hiccup. I'm ready to be proved wrong, but I have a hunch that any purported waterspout thwartings by gunshot stem from encounters where the spouts were already at the point of dissolution. Waterspouts aren't known for their longevity; still, a spout is going to break up when it's darned good and ready to. Until then, peppering away at it with  "a gun with the blast strength of a shotgun or better" (precisely what "or better" means is unclear to me, but I doubt it matters) isn't going to make much difference. I'm no expert on waterspouts, but I do have an opinion on them, namely, that waterspouts are  something to enjoy from a distance, avoid when boating, and respect as a phenomenon over which we have little control. As for breaking one with a gunshot, gee, why not? But first, let's you and me go on a snipe hunt. Now, you just stand over there in that swamp, hold this burlap bag open, and call, "Here, snipe-snipe-sniiiiipe!" while I circle around through the woods...

Waterspouts in the Lake Michigan Forecast

The marine forecast for Saturday remarked on the possibility of waterspouts on Lake Michigan. Kurt Hulst and I headed to the lakeshore in the hopes of seeing a few spouts, but we wound up disappointed. We initially targeted Holland, but once we arrived, it became clear that our best shot would be farther north where at least some convection was showing on the radar. So we headed up Lakeshore Drive to Grand Haven and parked in the state park. In a word, we got skunked. Decent vertical development didn't begin to show up until it was time to leave, around 4:00 p.m. Kurt needed to be home by 5:00 for a dinner date with his grandmother, so there was no question of sticking around. That was unfortunate, as some formidable-looking cloud bands were finally starting to roll in, and I'm left to wonder whether there were in fact any reports of waterspouts later in the afternoon. As for Kurt and me, we didn't see a thing, other than some very impressive surf rolling in on a stiff northwest wind. I've never seen a waterspout, and neither has Kurt. Today did nothing to change our unbroken record. Oh, well. Maybe next time.

Cool-Weather Wall Clouds

So there I was, driving down I-96 toward my mother and sister's house in Grand Rapids this afternoon, when I saw what at first glance looked like a wall cloud. It looked like one at second glance, too, and third, hanging off of a cumulus tower in the distance. Severe weather wasn't in the outlook today, and in fact, the afternoon was coolish and not particularly moist, with spotty showers but no thunder or lightning. I was unaware of any reason to be on the lookout for abnormal weather, though the extent of the vertical development in the cumulus clouds coupled with their nicely sheared look would have been a tip-off under more propitious circumstances. Anyway, I was intrigued by the cloud formation, but not quite prepared to call it anything more than a lowering at that point. It was falling apart over Grand Rapids by the time I turned north onto the East Beltline. But the show was far from over. Another large towering cumulus several miles to my northwest was exhibiting an even larger, blocky lowering which wasn't showing any signs of dissipating. That did it. It was time to get close enough to this thing to see just exactly what it was. This was a simple matter. The cloud was drifting quite slowly, and intercepting it involved nothing more elaborate than continuing north up the Beltline past 7 Mile Road, then pulling into a small turn-in, where I had an unobstructed view from maybe half a mile away. The cloud was indeed a wall cloud. I could see a weak updraft dragging scud up into it, and even a hint of an RFD. More important, the cloud was circulating--very slowly, to be sure, but unmistakably. As it moved closer, I even observed a small, anticyclonic vortex spinning almost directly overhead. There was obviously enough shear and helicity in the atmosphere to create some interest, and I had a nice front-row seat. Just wish I'd had my camera with me, but as I said, I wasn't expecting anything weatherwise today that would have made me think to grab it. What I was seeing struck me as more fascinating than threatening, but I decided to call KGRR and report it anyway, just for the record. The met who took my information said he wasn't surprised. He told me that the office had already received several reports of waterspouts out on Lake Michigan, plus other reports of funnel clouds. Sounded like a cold air funnel outbreak. My buddy Kurt Hulst called later to tell me that he, too, had seen a wall cloud over Caledonia from where he lives in Kentwood. If I'd been home, it would have been a front door delivery, but of course I wasn't. Seems to me, though, that Kurt said he got some photos. I hope so, because I'd like to see what I missed. Days like today just go to show that the weather does what it wants, when it wants. Maybe the local WFO will offer an analysis of today's conditions. That would be cool. Lesson learned: take my camera with me wherever I go.
