Greetings, friends and readers of Stormhorn.com!

I want to fill you in on some changes that are in the works for this blog. They’re not here yet, but they are impending, and I anticipate that they will help take the blog, and eventually its parent Stormhorn website, to the next level.

At the moment, the most significant change in the works is a brand-new, custom theme. My lady friend, Lisa, who is absolutely brilliant at website development, online marketing, and all things computer, has been beavering away steadily at the new version. When it is done, this blog will have a new look and much greater versatility. I’m excited about what Lisa has got planned, and I can’t wait to roll it out once it’s ready, see how you like it, and get your feedback.

Concurrent with the new theme, I’ve been thinking about adding an extra element of interest by featuring guest bloggers from time to time. They will be from the worlds of both music and storm chasing. I like the idea of offering you insights and perspectives besides just my own, and I hope that doing so will provide an added value for my readers as well as a positive experience for my contributors.

About my Jazz Improvisation E-BooK: While this project has been on the back burner for a while, I do anticipate picking it back up at some point. I’ve already got several installments written; however,  because I tend to be pretty thorough, each lesson takes me considerable time to develop, and with other more pressing matters to deal with, I just haven’t had time or focus for the e-book. Stay tuned, though, because it is by no means a dead project. As this blog and website continue to develop step by step, I will at some point get the e-book back on track.

So, there you have it: changes are coming to Stormhorn.com, and the first of them is right around the corner. Meanwhile, I’ll continue to post with the existing format, which has served me well thus far. I hope you’ve enjoyed your visits here, and that you’ll enjoy them even more as this blog enters an exciting new phase.

Out of idle curiosity, I ran the latest GFS and came up with the image below. The colored shading is 500 mb winds, and the contours are CAPE. Not shown: H7 temps of 4 C throughout Michigan, 50-60 kt bulk shear, and dewpoints in the mid-60s.

GFS for 00Z Friday evening, July 24.

CAPE stinks, but I’ve got to love that jet streak parked right over Grand Rapids. Without decent convective energy, this setup is hard to get too hopped up about, but it’s certainly worth keeping an eye on. Probably a pipe dream in July, but in this part of the country you just never know.

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.

A significant weather event appears to be shaping up for the northern plains and cornbelt this coming Tuesday. For all you weather buffs and storm chasers, here are a few maps from the 18Z NAM-WRF run for 7 p.m. CT Tuesday night (technically, 00Z Wednesday), courtesy of F5 Data.

A couple items of note:

* The NAM-WRF is much less aggressive with capping than the GFS.  The dark green 700mb isotherm that stretches diagonally through central Minnesota marks the 6 C contour, and the yellow line to its south is the 8 C isotherm.

* The F5 Data proprietary APRWX Tornado Index shows a bullseye of 50, which is quite high (“Armageddon,” as F5 software creator Andy Revering puts it). The Significant Tornado Parameter is also pretty high, showing a  tiny bullseye of 8 in extreme northwest Iowa by the Missouri River.

Obviously, all this will change from run to run. For now, it’s enough to say that there may be a chase opportunity shaping up for Tuesday.

As for Wednesday, well, we’ll see. The 12Z GFS earlier today showed good CAPE moving into the southern Great Lakes, but the surface winds were from the west, suggesting the usual linear junk we’re so used to. We’ve still got a few days, though, and anything can happen in that time.

Last week, my lady Lisa sent me a link to a very cool website called harlem.org, which invites viewers to “explore jazz history through one photograph.”

Now, the photo in question, taken by Esquire camera man Art Kane, is one I had seen before, and is in fact quite famous. Featuring a veritable who’s who of jazz history, all gathered together on the steps and sidewalk outside an apartment in Harlem, the picture is utterly remarkable. Count Basie, Lester Young, Coleman Hawkins, Dizzie Gillespie, Marian McPartland, Milt Hinton, Mary Lou Williams, Thelonius Monk, Sonny Rollins, Maxine Sullivan, Stuff Smith, Oscar Pettiford…all there, along with many others, fifty-seven in all. The patriarchs and the young lions, side by side.

Still more amazing, however, is how harlem.org has utilized this photo to give you quick, biographical insights into everyone who appears in it. Just mouse over the photo to a general area of interest, click, and that section of the photo is enlarged. Now mouse one by one over the musicians in the enlargement and their names appear in a pop-up balloon. And here’s where it gets good: when you click on a particular musician, a larger window pops up containing a photo and information about him or her.

What I’ve described is just a thumbnail sketch of what the site has to offer. If you’re at all interested in the history of jazz, this website is a must. It’s worth visiting just to see the photo alone, but I promise you, you’ll find much more of value besides.

Among the many interests that my sweetheart, Lisa, and I share is a love for photography. This last week we’ve poked around together in the outdoors with our Canon cameras and harvested a variety of images. So rather than write a lot of words, I thought I’d share a few photos with you. They’re about neither jazz nor storm chasing; they’re just odds and ends from nature and life at large.

Last weekend Lis and I headed up to Camp Henry, a Christian camp located on Kimball Lake north of Newaygo, to spend the Fourth of July with our close friend and dear sister in Christ, Kimberly Dunn. Kimber lives in Redding, California, but has been doing a summer internship here in Michigan at the camp. It was great to see her, and during our visit, Lisa and I naturally took a lot of photos.

Then yesterday, we went out on a photo expedition to capture prickly pear cacti in bloom. There is at least one species that is native to Michigan, the eastern prickly pear, Opuntia humifusa, also known as devil’s tongue. The blooming season for it is winding down, but there are still plenty of bright, butter-yellow blossoms available to fill a camera viewfinder.

With many photos to choose from, I’ve opted for images from nature and the outdoors, subjects that Lisa and I both gravitate toward more than anything else. I hope you enjoy the selection.
