The Action Comes to Michigan

Curious about the SPC’s Day 2 convective outlook for Michigan, I ran a few forecast soundings. Good grief! I can’t remember when I’ve seen skew-Ts like these in Michigan. The one for Cadillac reminds me of June 5, 2010, in central Illinois, though I think the winds above 500 mbs were stronger in that event.

It’s late and I’m not about to write a lot. But I have a strong hunch that tomorrow early afternoon I’m going to be heading north on US 131. It’s rough chasing in that part of Michigan, but anywhere in this state is challenging, and we don’t see this kind of setup very often.

June 9, 2012, North Dakota Chase Bust: Buy My Elephant

You can’t find a more quintessential border town than Pembina. It’s the last US town on I-29 before you hit Canada two miles to the north; and just across from it, on the eastern side of the Red River of the North, lie Minnesota and Pembina’s border-town twin, Saint Vincent. Tucked away in the northeast apex of North Dakota, Pembina is as far poleward as you’re ever likely to chase storms in the continental United States unless you find yourself pursuing wedges around Angle Inlet, Minnesota.

Last Saturday afternoon, Rob Forry and I gassed up at a filling station on the western edge of Pembina and contemplated the sky with fellow storm chasers Jim Parsons and Brian Spencer. The forecast models had been painting a frustrating picture, with a surface low moving northeast up into Manitoba and dragging southeast winds with it, leaving those of us without passports–which included me–with helicity-killing southwesterlies by the time storms started firing later in the day.

However, the HRRR was offering a glimmer of hope, stalling the warm front across the northernmost counties and maintaining southeasterly winds slightly south of the border as late as 01z. So there we were in Pembina in the mid-afternoon, gazing at a patch of altocumulus. On the way up, we had passed through an outflow boundary from storms earlier that morning, and now a brisk northeasterly wind reminded us that we had left the warm sector behind us.

The four of us grabbed lunch at a local restaurant, then parted ways. Most chasers were congregated well to our south near Devil’s Lake, where previous forecast soundings had looked pretty compelling. Unquestionably, instability would be present. Helicity and capping were the question marks, and even as we backtracked southward and then west, I had a hunch that we would eventually wind up playing back to the north.

In the tiny prairie town of Edmore–how do people earn a living in such remote places?–Rob and I found a shady place to park and wait for things to develop. We had passed back across the frontal boundary, and the temperature was warm, the winds were blowing from the southeast, and overhead, billowing towers kept thumping against the stout cap. We hung out in our new location for maybe half an hour with John and Brian, who had rejoined us, then took off. During that short time, the surface winds had veered to the south, so we headed back north on SR 1 to where the winds were once again blowing from the southeast and then parked.

Ten or fifteen minutes passed. A dot materialized far down the road to our south and grew larger, expanding and dividing into two rapidly approaching vehicles. It was our friends Ben Holcomb and Adam Lucio, in company with a small group of other chasers I had never met. They pulled aside and we all stood around and yakked for a while. Ben was suffering from a nasty ear infection which had hit him the previous night, and while he had managed to score some antibiotics, he was still pretty miserable. But with a friend visiting him from Finland for the express purpose of chasing storms, he was sticking doggedly with the chase. Must come from having lived all those years in Michigan, where a chaser’s character is shaped by supercell deprivation.

We hung with Adam, Ben, and their crowd for a while, then continued north. The surface winds had once again veered, and surface obs showed them blowing from the south-southwest not very far south of us. It seemed to me that if we were going to have any chance at all of seeing a tornado–and admittedly, chances were slim to begin with–it would be along the northern tier of counties in the instability axis.

At the town of Langdon, we headed west, and it wasn’t long afterward that we witnessed a tower finally break through the cap directly overhead and blossom into a full-fledged storm. We tagged with it for a few minutes, but with just a couple miles between us and the border, we didn’t have much room to play with, so we let it go for the chasers in Canada to try their luck with.

Meanwhile, another storm was intensifying to our south, and we headed east to intercept it. From there on, storms began to multiply, but there’s no point in going into detail. The cloud bases were higher than I had expected; the ambient surface winds, which had been brisk all day, seemed to sigh away into nothingness; and the storms were outflow-dominant and just garden-variety severe. Rob and I encountered a little half-inch hail, and at one point a nearby CG which I never saw struck behind me, producing a LOUD thunderclap that sounded like a rifle shot and scared the crap out of me.

But it wasn’t the severity of the storms that made this trip memorable. It was that minimalist landscape stretching its sameness in every direction out into infinity; and it was the dome of the sky, spreading its cerulean canvas from horizon to horizon over tiny communities scattered far apart across the prairie. There, a thousand miles from my Michigan hometown and over 100 miles farther north than the northernmost point of the Keweenaw Peninsula, that sky-canvas, daubed by the Great Painter with the texture and tincture of clouds and light, rendered the panoramic emptiness of North Dakota dramatic and beautiful.

The drive back on the following day was predictably long and, for the most part, uneventful. These last two photos mark what was probably the highlight of the return trip (barring dinner at a truly fabulous sushi restaurant in Janesville, Wisconsin). Rob snapped them for me at a gas station somewhere in Wisconsin or maybe Minnesota, I forget where. But the place wouldn’t be too hard to find again. It’s probably the only gas station in America that has a sculpture of a life-size pink elephant wearing black glasses standing at the edge of the parking lot.

Naturally, Rob and I both needed to pose in front of so imposing a creature, and it wasn’t until I processed the pics afterward that I noticed the realtor’s “For Sale” sign on the left. Really, though, it’s my sign. Would you like to buy my elephant? I’ll make you a great deal. It’s a very nice elephant, well-behaved and in excellent health except for a slightly embarrassing digestive disorder for which I’ve found no remedy other than to … well, you can see how I’ve handled it.

My First North Dakota Chase This Saturday

I’ve never chased storms in North Dakota, but that’s about to change. Tomorrow Rob Forry and I are hitting the road for the severe weather event that’s shaping up for Saturday along the Canadian border.

This has been a puzzling scenario to forecast, with the models gradually aligning after painting some radically different scenarios. The NAM has wanted to move the system eastward faster and place the better  tornado action across the Canadian border, while the GFS and Euro have been more  optimistic and, I believe–I hope–more accurate. What the heck–Canada may get more shear, but North Dakota has the big CAPE.

We’ll find out Saturday. Lacking an extended driver’s license that would grant me access to Canada, I’m counting on North Dakota to deliver. I feel confident

enough that it will that I’m taking the chance. I keep eyeballing the region from Minot east toward Rugby and Devil’s Lake, and north, and a bit south. Skew-Ts have looked consistently good in those parts, and there’s plenty of CAPE to get the job done–around 4,500  J/kg MLCAPE per the GFS. My hope is that all that luscious, pent-up energy will produce something like what the NAM 4km nested CONUS radar shows at the top of this post.

Come on! Big tubes and gorgeous storms drifting across the wide sublimity of the North Dakota landscape, and then steak and beer later on.

How to Solo on “Confirmation”: Guide Tones

In recent months I set myself to tackling a project that I had put off far, far too long: getting my arms around Bird changes. In one way or another, the Charlie Parker tune “Confirmation” has been a regular part of my practice sessions these days. Recently I finished transcribing a Richie Cole solo on “Confirmation,” and of course that was enlightening. I’m currently in the process of memorizing both it and a Parker solo on the changes. It has all been profitable in unlocking the logical but nevertheless challenging harmonies.

Developing a set of guide tones is immensely helpful in mastering Bird changes, particularly in the first four bars. The exercises on this page will help you do so. Click on the image to enlarge it. Note that the exercises are written for Eb instruments. If your instrument is pitched differently–eg. Bb tenor sax or C flute–you’ll need to transpose accordingly.

In exercises one and two, I’ve stripped the guide tones down to a whole note for every bar. You can modify them as you wish, but I find it helpful to start by keeping things as simple as possible.

Exercises three and four take the form of boppish etudes that utilize the guide tones.

I highly recommend that you practice these exercises with some form of harmonic accompaniment so you can hear how the pitches sound in context with the actual chord progression.

That’s it–gotta scoot. I hope you find these little nuggets profitable. If you enjoy them, you’ll find plenty more on my jazz improv page.

Memorial Day 2012: A West Michigan Lightning Extravaganza

I have yet to take some truly razor-sharp images of lightning, but each time I go out, I learn a little more about how to improve my lightning photography. Last night afforded me a great opportunity. Storms forming ahead of a cold front moved across Lake Michigan and began to increase in coverage as the night progressed, and I roamed with them across West Michigan from the shoreline at Whitehall and Muskegon State Park to inland northeast of Lake Odessa.

My expedition was marred by the fact that I left the adapter plate for my tripod at home. I compensated by setting my camera on top of my dashboard and shooting through the windshield, an arrangement that works okay but

which considerably limited what I was able to do at the lakeshore. Using the hood of my car to steady myself, I managed to capture a few shots of a beautiful, moody sunset, with the red semicircle of the the sun gazing sullenly through rain curtains of the advancing storms. However, parking by the side of a busy road where everybody had the same idea–to pull over and watch the storms roll in over the waters–just didn’t work very well. After too many time-lapse images marred by tail lights (see photo in gallery below) I decided to hightail it and try my luck inland.

It was a good choice. The storms multiplied as I headed back toward Caledonia, and with lightning detonating to my north and closing in from the west, I decided to continue eastward till I found an ideal location–a place far from city lights and with a good view in all directions. I never expected to drive as far as northeast of Lake Odessa, but I’m glad I did.

Note to self: STOP USING THE ULTRA-WIDE-ANGLE SETTING WHEN SHOOTING LIGHTNING. Zooming out all the way to 18 mm is just too far, and cropping the shots doesn’t work well. The crispness goes downhill.

For all that, the images below aren’t all that bad, and a few turned out really well. After Sunday’s busted chase in Nebraska, it was nice to enjoy a few mugfulls of convective homebrew right here in West Michigan. I finally arrived home at the scandalous hour of 4:15 a.m., far later than I ever anticipated. I was tired but pleased. This Memorial Day lightning display did not disappoint.

An Active Weather Pattern Moving In

These next few days look interesting severe-weatherwise from the northern Plains into the Great Lakes. Today holds the potential for a significant blow near the Missouri River in South Dakota, Minnesota, Nebraska, and Iowa. Here is a RAP forecast sounding for Sioux Falls, SD, for 00z tonight.

I’ve been eyeballing that area via the NAM for a number of runs. Capping has been an issue for a while now, but NAM has consistently wanted to break the cap in the area I’ve mentioned. If I could have found a partner to split costs, I’d have left last night, but the thought of going it alone and blowing a wad of cash on a cap bust–a distinct possibility, with 700 mb temps hovering AOA 12 degrees C–spooked me.

Now I think I should have taken the risk. Today could be another Bowdle day, and I wish I was in Sioux Falls right now. Some of the  indices there for this afternoon look pretty compelling, at least if the RAP is on the money. The cap could break between 22-23z, and if that happens, then walloping instability (mean-layer nearly 3,900 J/kg CAPE and -10 LI) and mid-70-degree F surface dewpoints will surge upward into explosive development, and ample helicity will do the rest.

However, the SPC is not nearly so bullish as the above sounding, citing the complexity of the forecast due to capping and the lack of dynamic forcing. That’s been a repeated theme. Today looks like one of those all-or-nothing scenarios where chasers will either broil in a wet sauna under merciless blue skies or have one heck of an evening.

Boom or bust for those  who are out there. As for me, this evening I will either be watching the radar and beating my head against the wall or else congratulating myself on my good fortune for not going.

But I’ll also be packing my gear in preparation for tomorrow, and later tonight I’ll be hitting the road with Bill and Tom. I’m uncertain what Sunday holds, but last I looked, the dryline by the Kansas-Nebraska border looked like a possibility on both the NAM and GFS. The weak link seems to be the dewpoint depression; it’s wider than one could hope for, suggesting, as the SPC mentions in its Day 2 Outlook, higher LCLs. I haven’t gone more in depth. We’ll look at the model runs again tonight and pick a preliminary target for tomorrow.

Confirmation: A Richie Cole Alto Sax Solo Transcription

I am not the world’s most accomplished jazz solo transcriber, but every time I tackle a project, I discover anew just how beneficial the discipline of transcribing jazz solos is. This latest transcription has kicked my butt. Richie Cole is–to put it in words you’ll rarely hear from a sedate, late-middle-aged Germanic male–one bad mofo on the alto sax. He has carved his niche as a bastion of bebop, and as such, his language is largely accessible. However, Richie has a way of interpolating material that requires serious effort to figure out exactly what the heck he’s doing.

So it is with his rendition here of the Charlie Parker standard “Confirmation.” Some of Richie’s rhythms and trills caused me to sweat blood for hours trying to at least approximate in a measure or two ideas that flew glibly from the man’s horn in the matter of a second.

The solo is transcribed from Richie’s 2007 CD The Man with the Horn. A quintessential bebop tune, “Confirmation” rips along at 246 beats per minute, providing Richie with a perfect vehicle to demonstrate his formidable chops and his broad bop vocabulary. Anyone who wants to gain mastery of Bird changes will profit from working on this one.

Note: I transcribed Richie’s solo for Eb instruments, specifically the alto sax. I haven’t attempted to show all of Richie’s slurs and nuances, just a few that I felt needed to be indicated. To get a real feel for his articulation, you’ll need to listen to the recording.

Photos from the April 14, 2012, Kansas Tornado Outbreak

May has been an astonishingly idle month for chasing storms, at least from the standpoint of a Michigan-based chaser who can’t afford to travel a thousand miles to tornado alley on every whim and wish of a slight-risk day. So tonight I finally got around to capturing a few still images from my video of the April 14, 2012, tornadoes in Kansas. Please excuse the graininess. These are, after all, video grabs, and the original footage was shot right around and after sunset. So … not high quality, but great memories of an exciting and rewarding chase day. You can read my written account of it here.

Along the Long Lake Trail

This has been the quietest May I can recall weatherwise. The peak month that I and hundreds of other storm chasers have spent the better part of a year anticipating has turned out to be a dud. Maybe around the latter part of the month things will improve, but there’s nothing to look forward to for at least the next week.

If the weather isn’t going to offer anything chaseworthy, then the way it has been is exactly the way I want it to be: blue, crisp, and beautiful, warm but not hot, with the sun smiling down on a landscape that’s getting on with the business of spring.

A couple days ago, I took a walk down the Long Lake Trail just north of Gun Lake State Park in northern Barry County’s Yankee Springs Recreational Area. It had been a while since I had hiked the trail, and this time of year is perfect for the venture, so off I went. The first mile or so of the trail winds through hardwood forest, skirting a small bog and a tract of red pine, then sets you on a quarter-mile stretch of boardwalk through part of the swamp that surrounds Long Lake. It’s a lovely hike that offers plenty to see if you know your native plants and their habitats.

Here are a few of the highlights. The odd little plant to your right, which somewhat resembles miniature corncobs, is called squawroot (Orobanche americana). It is a common woodland plant, parasitic on oak trees. Click on the image to enlarge it.

The trail winds through some particularly pretty territory. The photo below gives you an idea. There are a number of other images at the bottom of this page to keep it company.

Ferns were in the process of unrolling their fronds. They never look more dramatic or more artistic than this time of year, when they’re in their “fiddlehead” stage.

Farther down the trail, where the boardwalk commences, marsh marigolds scattered Pointillistic fragments of butter-yellow across the swamp floor. Picking up on the golden theme, the first few flowers of small yellow ladyslipper orchids (Cypripedium calceolus var. parviflorum) peeked out shyly from among lush skunk cabbage leaves.

The swamp is full of poison sumac, a small tree with which I’ve had considerable experience recognizing and avoiding. It is related to the cashew and also, of course, to poison ivy. Eating poison ivy at age six was not one of my intellectual zeniths, and it’s not an experiment one should undertake casually. Long after the initial bitter burst of flavor has faded, the experience lingers in a way a body is not apt to forget. Word has it that poison sumac is even more virulent than poison ivy. That’s not something I care to put to the

test. Interestingly, the sap of its equally toxic cousin, the Japanese lacquer tree, is used as a varnish which produces some beautiful objets d’art, though how a body works with a medium like that is beyond me.

But enough of the swamp and its sumac. Stepping off the far end of the boardwalk and farther into the woods, I encountered an elegant young beech tree standing sentinel on a mossy bank.

I walked a bit farther, then turned back. The slanting sun rays were filtering long through the leaves, the temperature was cooling, and it was time for me to go practice my horn–which, by the way, I’ve been doing pretty consistently. But that’s material for another post. Right now, check out the rest of my photos in the gallery below.

Picking Up the Horn Again after Being Sick

Thursday evening, April 12, I left Grand Rapids to go chase storms out west. It was a great time and a successful chase, but on the way home Sunday night I began to cough, and the cough blossomed into the worst case of bronchitis I’ve ever had. For two weeks, I languished. My activity was limited to coughing, and coughing, and coughing some more; prostrating myself before the vaporizer for extended inhalation sessions punctuated by periodic steamy showers; slurping down massive quantities of fluids; and sleeping like I never planned to wake up and didn’t want to (which, indeed, I didn’t).

Over the past three days, I’ve finally begun to feel human again. Today I woke up feeling pretty good, with just a remnant of a cough and my voice returning to some semblance of its normal self. What a relief!

Naturally, I was pining to get at my saxophone. Three weeks away from it is way too long. I’d been in top form when I left for Oklahoma and Kansas, and now I’ve got some ground to recover.

So this evening I grabbed my horn and headed to my beloved railroad tracks, where it’s my wont to park my car, work over my horn, and wait for the trains to roll by. Out by a crossing near the rural community of Alto, I assembled my beautiful Conn 6M Ladyface and began to blow the rust out of my fingers and the cobwebs out of my head.

It felt so good!

There is something about reuniting with my saxophone after an extended period away from it that feels at once awkward, restorative, frustrating, cathartic, and encouraging. The awkwardness and frustration come from having spent enough time not playing my instrument that it feels a bit foreign to my hands, not quite the comfortable extension of me that it normally is. My technique isn’t as smooth, and material I had recently been practicing has to be called back to memory. The encouragement arises with the discovery that, hey, I don’t sound all that bad, regardless. In fact, I sound pretty good. Something about the time away seems to tap into reservoirs of creativity I didn’t realize existed, and if my playing isn’t quite as facile as I’d like, there’s nevertheless a compensatory freshness to it. My fingers don’t fall as readily into the same glib patterns, and so instead they find their way toward new ideas.

As for the restorative and cathartic aspects of picking up my saxophone after a lengthy period of illness, do I really need to explain? It’s just such a marvelous feeling to play again, to experience the physicality of making music: the balanced resistance and give of the reed in conjunction with my airstream, the feel of the keys beneath my fingers as I practice patterns and craft spontaneous melody lines. There’s nothing like it.

With the arrival of spring weather, I’ve been pretty consumed with storm chasing. The chase season is here for a limited time, and one must make the most of it while the opportunity is there. But the musical part of me doesn’t at all go dormant during storm season. I prioritize chasing over musical engagements, but not over the music itself. I continue to practice and push myself as a saxophonist, even if the bulk of my blog posts during this season focus on severe weather.

Tonight I’m taking a hiatus from the weather to reflect on this other part of myself, the musical part. How good it feels to play! Thank you, Lord, for the gift of music–for this amazing instrument you’ve placed in my hands, and for the passion and the drive to continue striving for the mastery of it. It is such a joy to play my horn once again!
