I’m visiting with my youngest brother, Brian, and his family in Dallas. Brian and I are the musical bookends among our siblings, Brian having earned his music degree at North Texas State University and gone on to make his living as a professional drummer. I haven’t yet shown him the following link. I’m sure he’ll feel stunned to know how easy playing the drums really is. Yes, stunned is no doubt the word. You don’t even need drums, not today in this age of quality technology. All you need is the miraculous keyboard featured in this video. If you’re playing rock and roll, just make sure to play the bass drum on da firs’ beat and on da turd beat.

Heaven help me and all other horn men if the guy in the video ever turns his eyes toward the saxophone. We’ll all be out of a job.

After years of planning and digging for research dollars, VORTEX 2 finally hit the pavement this spring, only to be met with a severe weather famine. It had to have been heartbreaking for the team, watching that merciless, unending ridge stretch from day to day and week to week, knowing that the clock was ticking on their window for gathering data.

Thankfully, tornadic storms hit the Plains before the window closed, and the team got what they needed. I wish it had gone as well for me. My tally for this season has been one tornado. But I did at least get the compensation of catching some nice storms with cool structure, including the June 7 supercell in northwest Missouri that every chaser in the country seemed to be after–including, of course, the VORTEX 2 armada.

Just for kicks, here is a shot of one of the DOW trucks–the new one with the square radar rig. I believe I took this shot south of Forest City. The DOW is parked to the left in the photo, and I’m looking at it head-on. Viewed from that angle, the radar unit looks like the front end of a tractor trailer.

Sure does bring back memories. I hope I’ll get a chance to make a few more before the chase year closes. Prime storm season is over, but it’s still a long time yet before the snows fly.

Morning. I’m still in bed, and from the next room, sounds of family are drifting through the door. I’m in Dallas with my sister Diane, visiting with my brother Brian, sister-in-law Cheryl, and little nephew Samuel. Since the last time I saw him, Sam has transitioned from babyhood to little-boyhood. He has acquired a vocabulary, a white baseball cap that it’s very important to wear (backwards or sideways, as is the custome), and a very cool train set that we played with last night.

My lady Lisa is holding down the fort back in Grand Rapids, where the weather is providing a much cooler contrast to the upper-90s heat that’s on the menu for this week here in north Texas. Chasing storms is of course out of the question. I’ve family to visit, a bit of work to do, and in any case, there are no storms. Summer has hit and the atmosphere is capped as tightly as an oil drum. On Stormtrack, chasers are bidding the 2009 chase season adieu. I note that the SPC has outlooked days 5-6, but they’re not using the kind of language that gets me very excited.

I’m keeping this short. I can hear the sound of forks clicking on breakfast plates. It’s time to shower up and get myself going.

Looking north along the Lake Michigan coast at sunset.

Sax anywhere is great, but sax on the beach is fantastic.

Take a Squeegee to your naughty mind. I’m talking about playing the saxophone, thank you, and about one of the places where I particularly enjoy playing it. There’s something very special about heading out to the lakeshore and practicing my saxophone accompanied by the sound of the waves and the cry of the seagulls.

If you follow the jazz side of this blog, then you know that I love to play my horn outdoors. My practice habits are fairly eccentric in that regard. Many years of apartment dwelling, which include neighbors whom I haven”t wished to disturb, have taught me that my woodshed is wherever I choose to make it. The state parks. The cow pasture at the edge of town. Most often my own car, parked by the railroad tracks out in the countryside.

But there’s no place quite like the shores of Lake Michigan.

It’s been a long time since I’ve taken my horn out there, but yesterday provided a reminder of what I’ve been missing. Regretfully, I didn’t have my saxophone with me, but I did have my sweetheart and best friend, Lisa. From our little outing in Muskegon State Park, I thought I’d share a few images with you of…

sailboats out on the waters…

…the north boardwalk along the Muskegon channel…

…dune grass silhoutted by the setting sun…

As for the great sand dunes that are one of the hallmarks of this beautiful state, I’ve already given you a glimpse of them up at the top of the page, but the really imposing dunes lie in the northern and southern ends of the Lower Peninsula. Perhaps in another post I’ll include some shots of Sleeping Bear, Warren Dunes, P. J. Hoffmaster Park, and Nordhouse dunes–vast tracts of sand, marram grass, and wooded dunes that reflect the wild beauty of the Michigan outdoors. It is a wide open sublimity that speaks to something deep inside me, and that has colored the music I play for many years.

One of these days soon, I will visit the lakeshore again–this time with my saxophone, to serenade the gulls, the waves, the far-stretching sands, and the setting sun.

Earlier today, I opened up GR3 just out of curiosity and noticed some blobs of convection along the Lake Michigan shore by Chicago. Here are a couple radar grabs.

These images interest me for several reasons, all of which have to do with a Great Lakes phenomenon called the lake breeze zone. The lake breeze zone is not a fixed area. Its boundaries are atmospheric, not geographic.

And boundaries truly are what it’s all about. Probably the most immediately noticeable feature on these radar images, besides the obvious storms, is the north-south boundary set up by the onshore breeze. It’s a great point of convergence where overall westerly surface winds butt up against backing winds from off the big lake. You can see how outflow from the storms that have fired up within the lake breeze zone interacts with the lake breeze boundary.

Another less immediately obvious by-product of the lake breeze zone is helicity. Notice how the wind barbs farther inland are all westerly, but inside the lake breeze zone, they’re easterly. Now, I’m no expert on this stuff, but I know enough to recognize the potential for localized helicity to occur even when the large-scale flow is unidirectional. During the day, strong thunderstorms can go tornadic when they encounter a backing onshore breeze near Chicago, along the Wisconsin shoreline, and along the Lake Huron and Lake Erie shores of eastern Michigan. The same can happen in the evening along Michigan’s western coast as the land cools and an offshore breeze prevails. Many times I’ve noticed the NAM and RUC showing a small sigtor centerered over Berrien County when there are no sigtors anywhere else in the region, and I’m sure this phenomenon is largely due to the lake breeze in that area.

Right now I see storms firing up farther north around Gladwin and Roscommon.

A glance at the Gaylord VWP shows west winds neatly stacked from the surface on up. But look at the METARs along Lake Huron. Without much in the way of bulk shear, the storms are subsevere, just little popcorn cells. But it will nevertheless be interesting to see what comes of them as they work their way into those backed shoreline winds. You just never know.

The SPC has placed Michigan and the Great Lakes in a slight risk area for tomorrow. But tornadoes aren’t in the picture. The summer pattern appears to be setting in, with the jet stream moving its headquarters to the US/Canadian border. As far as Michigan is concerned, that’s close enough that we can still expect some decent kinematics here and there. But what we get tends to result in linear MCSs more than supercells and the like.

Tomorrow’s SBCAPE should settle in between 2,500 and 3,000 j/kg, with dewpoints in the 70s. That’s certainly an ample supply of convective fuel. And F5 Data shows this for H5 wind speeds at 21Z:

If you can live with northwest flow, that’s not bad. But of course, the underlying winds are all westerly. Once again, Michigan’s energy will get sabotaged by unidirectional winds. How pathetically par for the course! Maybe we’ll get some supercells, but we’re unlikely to see the low-level helicity needed to make them tornado producers. Probably better knock on wood when I say that, because the lake breeze zone can do some funny things with locally backed winds. Overall, though, I think the order of the day will be some nice, burly, ouflowish thunderstorms.

What do I know, though? I’m still pretty green as a forecaster, and I recall a couple years ago when the models showed a unidirectional setup with nothing in the way of helicities, and an F3 tornado ripped through Potterville.

One of the nice things about living in Michigan this time of year–among the many wonderful advantages of this beautiful state–is that we’re prone to get a couple supercellular events when the traditional Tornado Alley of the Great Plains simmers under a titanium cap. Those occasions aren’t anything you can count on, but it’s nice when they happen–for me and my fellow storm chasers, anyway. I suppose other folks here might see things a bit differently.

My friend and fellow musician Dave DeVos once told me, “You are the loudest sax player I’ve ever known.”

His words weren’t a compliment, just a statement of fact tinged with a slight mix of incredulity and annoyance. I’m a very loud sax player, much louder than I realize. As the old cliche says, I don’t know my own strength.

Of course I can play softly, but soft is not my default mode. Part of that is attributable to my horn, which is an old Conn 6M “Ladyface” that is very good at translating the air I move through it into immense volume levels. Another part is due to my mouthpiece, a Jody Jazz classic #8. But I think the main reason I’m a loud player is directly linked to the guy behind the horn. I just seem to have a knack for massive sound output.

I wasn’t always a loud player. I entered my freshman year in college a quiet young saxophonist. My sound at the time was styled after Tom Strang, a local alto man who owned a jazz bar in Ada called the Foxhead Inn. Tom had a smooth, mellow sound, very pleasing to the ears. He was not a loud sax player.

As an early influence, Tom’s tone pointed me toward a somewhat Desmondesque approach, not exactly the kind of robust Cannonball sound that could melt the wax in a listener’s ears at 100 feet. It was more a kind of foofy-foof-foof tone–subdued and, I thought, pleasantly sophisticated.

It was this mellow, sedate sound that I brought with me to the student big band at Aquinas College, where I sat under the august directorship of jazz professor Bruce Early. I was assigned to the first alto chair, and my lack of experience was such that I felt eminently qualified to fill the position. Clearly word of my abilities on the sax had preceded me, and Bruce had simply placed me where he knew I belonged. First chair. It was inevitable.

I’ll never forget my first awakening to the possibility that maybe I wasn’t all that and a supersized order of fries. The band was playing through some tune I’ve long since forgotten, and in the middle of the chart there was space for an alto solo. Cool. A chance for me to show my stuff, give Bruce a taste of my chops. I launched into the solo. Foofy-foof-foof, I played, subtly, while the rhythm section whanged away.

Bruce stared at me. “Play louder,” he said.

Ah. Louder. Okay then. Foof-foof-foofy-foof! I declared, in a volume that could almost be heard from ten feet away.

Bruce’s stare became a glare. “Louder!” he barked.

My gosh, what did this guy want? Here I was, foofing as loudly as ever I had foofed, and Bruce was calling for more.

I returned his glare with a desperate glance.

Foof? I played. Foofy-foof!

I was trying, but I quickly trended toward the softer, cocktail lounge volume that I was used to.

That did it for Bruce. “BLOW!!!!” he yelled. “For crying out loud, BLOOOWWWWW!!!!!!”

Some of the more seasoned musicians snickered, and my face went red as a beet. Hell’s bells. Fine, if it was volume Bruce wanted, I’d give him volume. And I did. I had a lot to learn about embouchure and tone production, but at that point I instinctively dipped into the raw essentials, filled my lungs with air, and blew my ever-loving cheeks off.

From that time on, while Bruce yelled at me for any number of things, my volume level wasn’t among them. He never again complained that I was playing too softly. Nor has anyone else, for that matter. Not ever. I’ve played with highly amplified blues bands and church worship teams and outblown them without using a microphone. I’ve been asked plenty of times to turn it down a bit, please. But no one has ever come to me and said, “Could you play louder? I can barely hear you.”

Just ask Dave. He’ll be glad to tell you, as soon as his ears stop ringing.

Approaching the storm of the day south of Normal, Illinois.

After Iowa’s blue-sky bust on June 18, yesterday provided some welcome and much-needed activity. Between illness and May’s ridge of steel, my chase expeditions this year have been limited. The Edina, Missouri, tornado of May 13 has been my only tornado to date for 2009. Yesterday did nothing to improve that statistic, but it did offer a vigorous, classic supercell with some great structure that ensured my 1,650-mile, two-day chase with my buddy Bill Oosterbaan wasn’t a complete washout.

For that matter, storms did finally fire in eastern Iowa, and while Bill and I were too late to catch the big mutha that slammed Prairie du Chien (Ben Holcomb, if you happen to read this, great job on tracking that beast into the hills and jungles of Wisconsin!), we did manage to latch onto the one that followed in its footsteps. But I’m no fan of night time chasing and neither is Bill, and knowing the kind of topography that lay to our east once we crossed the river, we dropped our chase at Prairie du Chien and found ourselves a hotel.

After a decent breakfast yesterday morning, we were on the road by noon and headed south. The SPC showed a moderate risk for a large area extending from Iowa and Missouri east across the corn belt and Great Lakes. With a continuation of yesterday’s huge CAPE and good bulk shear, a widespread severe weather outbreak seemed like a sure bet. However, veering surface winds and unidirectional flow seemed to put the kibosh on chances for tornadoes in all but a few areas to the east, where helicities improved, particularly around 21Z.

As we approached Davenport, Iowa, heading south, we could see towers muscling up along an east-west boundary that transected Illinois south of the I-80 corridor. Catching I-80 east, we could see new cells firing up farther to the south on GR3. With a Kankakee target in the back of our minds, we decided to drop toward Normal on I-39.

By the time we drew near the town, the northernmost storm was showing rotation on the radar. The tower was just to our west, and as we proceeded down the highway, the updraft base came into view, dominated by a well-developed wall cloud.

We headed for an intercept, tracking with the storm until it began to degrade. Meanwhile, another cell to the south was strengthening and beginning to exhibit distinct rotation on SRV, so with the storm we were on mushing out, we abandoned it in favor of the second, rapidly intensifying supercell.

One heckuva hail shaft or what?

This bad boy had an impressive hail shaft, if hail is what we were actually seeing. Maybe it was just plain old rain with a bit of hail mixed in. The reason I wonder is because of the paucity of hail reports. We got tapped a bit as we closed in, but mostly we just encountered buckets of rain. Whatever the case, the updraft tower with the sunlit precip column was a beautiful sight.

Second storm showing sunlit precip core and updraft tower.

After working our way south of the storm’s rear flank, we proceeded east and finally gained some good, clear views of the business end. Tracking with it from near Urbana through Homer, Fairmount, and Westville toward the Indiana border, we were in a good position to enjoy the structure as the storm went through several cycles.

Rotating wall cloud.

Just east of Homer, the wall cloud tightened and I could see rapidly circulating cloud tags descending toward the ground. We pulled over to watch. The rotation wasn’t far away–maybe a quarter of a mile–and it appeared to be moving toward us. This was strange as we were southwest of the wall cloud, but you can’t argue with a developing tornado. With the updraft approaching to within a couple hundred yards of us, Bill seemed intent on analyzing why the storm was acting so peculiarly, while I favored beating a hasty retreat and working out the behavioral aspects of storm circulation from a somewhat greater distance. Storm chasing sure has its interesting moments.

No tornado materialized, the storm headed east, and we continued on with it. I noticed a couple of tornado reports from around Fairmount and Westville, but while I suppose it’s possible that there was a brief spinup or two, Bill and I never saw an actual tornado. We did witness a few times when the wall cloud began to torque  pretty intensely, and I sure wouldn’t have wanted to be directly below it.

The whitish wall cloud is half a mile from us and rotating vigorously.

Possibly a funnel cloud at this point.

But from the time we first intercepted it to the point where it finally began to fizzle 120 miles later west of Crawfordsville, Indiana, the storm was outflow-dominant. Never once did we enounter surface inflow, though above ground level, I’m sure inflow was strong. In Bill’s words, the circulation kept reaching toward the ground, looking for something to grab onto, but it never could manage to root and produce a tornado. If we’d had backing winds…if the helicities had been there…I’m sure the storm would have been a potent tornado breeder. It never got its act together in that regard, but I doubt the communities in its path felt terribly disappointed, and from my perspective, the storm provided an interesting chase with some very nice moments.

Last gasp: wall cloud at US 41 west of Crawfordsville, Indiana, shortly before the storm began to collapse.

For sheer structure, the “Danville supercell” was interesting and photogenic, with some nice RFD slots wrapping in, and, toward the end of the storm’s career, with a classic, stack-of-plates mesocyclone that was as nice as anything I’ve ever seen. (Sorry, no photos–the ones I have didn’t turn out well.)

One downside to this chase–and it is a big one–is that somewhere between Homer and US 41, I lost my camcorder. It wasn’t a pricey camcorder; it was a used Sony that I bought from my friend and fellow storm chaser Kurt Hulst. But it has done me good service over the past year, and I hate to think that it is presently sitting out there by the side of some Illinois backroad. What’s even worse is, my video of this chase is in it.

The drive back to Grand Rapids was a long one. I arrived at my apartment around 2:30 a.m. and collapsed. The chase was fun and I think I needed it, but it’s good to be back home with the love of my life, Lisa, whose bright eyes and beautiful smile warm my heart wherever I travel.

Thanks to a merciless cap, action in Iowa didn’t start yesterday until shortly before dark, and it never came close to living up to its potential. The RUC majorly underforecast convective inhibition, resulting in a lot of broken chasers’ hearts around Waterloo, mine included.

Storms finally did fire to the east, and a beautiful supercell crossed the Mississippi River after dark at Prairie du Chien, Wisconsin, where Bill and I have overnighted. We wound up on another cell that slowly organized and went supercellular, following in the first storm’s track. There were a number of storms in a cluster that showed rotation, but none of them put down tornadoes.

Today’s event looks to be widespread, and Michigan could very possibly see some action. But Bill and I are looking toward western Illinois. Galesburg presently looks good, or maybe Davenport. The storms are already getting their acts together. Time to sign off, check out of this hotel, and get on the road.

As I write, I’m heading west down I-80 with my storm chasing buddy Bill Oosterbaan. Our target: Waterloo, Iowa. The 9Z RUC shows a nice convergence of 850 and 500 mb jets overspreading massive CAPE by 21Z, with a robust 200 mb jet nosing in. Progged surface winds could be better, but skew-Ts still show nice veering with height, and storm relative inflow is majorly backed.

Oh, yeah…and we’re looking at dewpoints of 75 degrees and higher, with dewpoint depressions around 5 degrees. LCLs should be so low we may have to tunnel underground to find the cloud bases.

The SPC has hatched out this area for tornadoes. No surprise. After a relatively modest season, we may be on the verge of a significant outbreak. It’s a bit sobering to think that Parkersburg, Iowa, could get slammed again. I expect we’ll see a PDS statement at some point today, and I wonder whether the outlook won’t get bumped from a moderate risk to a high risk as well.

Tomorrow also looks to be a hugely active day, and the latest SREF places a sigtor in Michigan. So stay tuned. I’m sure there will be more to come.
