Bundling Up for a Michigan Blizzard

As I begin this post, around 5:20 p.m. EST, the KGRR metar shows a temperature of 35 degrees here in Grand Rapids, Michigan. Not far to the southwest, though, closing in on Chicago, northeast Illinois is giving reads of around 20 degrees. The backside of the low pressure system that has brought us a

wintry mix is preparing to bring considerably colder temperatures down upon us, wrapping in from the northwest and west as the low lifts up into Canada.

So far, conditions really haven’t been bad at all, certainly not as bad as the scenario the NWS has painted with a blizzard warning commencing at 1:00 p.m. But I’m sure the weather will worsen; it’s just a matter of time. The guys at the local WFO have the unenviable  task of forewarning the public of potentially lethal winter conditions without coming up looking like goobers when the blob of Jello-O they’ve got to nail to the wall doesn’t entirely cooperate. Predicting severe warm-season weather is tough enough, but forecasting winter weather is a whole different kettle of fish entirely, and my guess is, it’s a harder one to get right.

Anyway, here’s what’s presently sitting on top of us here in Michigan. The topmost image is a 2200Z map showing current pressure and wind barbs. The bottom one is a level 2 radar grab with metars. Click on the images to enlarge them. They depict conditions at the time of the evening commute, which aren’t too bad; they also indicate what’s on the way, which isn’t too good. We are gonna get socked, methinks. But that’s okay. Lisa and I have got a couple Christmas movies to watch, good beer, plenty of food, the warmth of each others’ company, and the blessing of the Lord’s presence in our humble but comfortable apartment. Really, it doesn’t get much better than this.

Major Winter Storm on the Way for the Great Lakes

It starts out as a relatively small, innocuous-looking low straddling the California and Nevada border, but by Wednesday afternoon, look out. It’s no longer out west and it’s no longer meek and mild-mannered. According to

today’s 12Z NAM, it’s perched squarely over Michigan, and with a sea level pressure of 976 mbs at 18Z and continuing to deepen, it’s downright ugly. (Click image to enlarge.)

El Nino, Schmell Nino–we are in for one heck of a Great Lakes bomb. The NWS office here in Grand Rapids is calling for a wintry mix in my area changing to all snow, and nothing but snow starting just a little farther north. Wherever you live in the western Great Lakes, though, Wednesday and Thursday are not going to be pleasant. Get set for a one-two punch of winter precip followed by a windy blast of very cold air wrapping around the back of the low as it tracks northeast into Canada, intensifying on the way.

Time to stock up on supplies. Unless you’re a winter weather freak, Wednesday is not going to be a pretty picture.

You’re a Good Man, Charlie Brown

This post is a continuation off of the previous one. Last night was the final night of the stage musical “You’re a Good Man, Charlie Brown” in Hastings. The show enjoyed a decent and enthusiastic turnout. Today, as I reflect on it, I want to say what a truly impressive job the young actors turned out. These small-town high school kids rendered an absolutely stellar performance, and it was a privilege for me to have played a small part in making it happen.

What I saw onstage clearly reflected a lot of talent, dedication, focus, hard work, enthusiasm, and friendship and mutual supportiveness among the cast. The result was not merely a superb production, but also a joyous one, and, frankly, a touching one as I consider the network of human relationships that lay behind it.

To any of the teen performers who happen to read this post: Bravo! Splendidly done! Charlie Brown, Linus, Lucy, Snoopy, Sally, Schroeder–each of you did a fantastic job. I’m well aware that there were plenty of others who helped make it happen–supporting cast, stage help, directors, and so on. My congratulations and appreciation goes to you all.

God bless each of you. Enjoy the afterglow of a magnificent show–and have a wonderful Christmas.

Playing Jazz on the Local Level

Last night I spent an enjoyable evening playing in the orchestra pit for a production of the stage musical, “You’re a Good Man, Charlie Brown,” in Hastings, Michigan. Tonight I’ll be there again, and tomorrow night. The cast is all high school kids, and they do a great job. My buddy, Ed Englerth, is sitting in on guitar, and Mark Ramsey on keyboards serves as musical director and does by far the bulk of the actual playing. My job is to keep my ears open and provide improvised sax work wherever it seemed appropriate.

If that sounds like a rather loose approach, it is. But the informality and spontaneity are a good part of the fun for me. You see, we’re not talking some high-pressure effort here that has involved weeks of practice (my preparation consisted of attending the dress rehearsal, then walking in last night and playing the gig). This is a local, grassroots production–which is by no means to minimize the talent, just to recognize a difference in approach that I really enjoy. That’s what’s nice about local efforts: they have an irreplaceable, homespun feel; they are high in entertainment value; they are often very well done; and they tap into and foster the gifts that are right at hand. Some surprisingly bright stars may be shining far from the Big City in a small town near you.

This has been my first time playing with Mark Ramsey, and I’m impressed by his level of professionalism. Hastings, the capital of Barry County, Michigan,  is a small town blessed, as is many a small town, with a number of good musicians. My friend Ed Englerth, for instance, is an absolutely brilliant songwriter. Trumpet man and vocalist Joe LaJoye, the town’s retired band director, is the driving force for jazz in the community and the spearhead of its annual jazz festival. And Mark is the first keyboard player I’ve encountered in the area who demonstrates a well-rounded command of his instrument, one that shows a grasp of many idioms ranging from jazz to show tunes to classical and more. And he’s a very nice guy to boot. No attitude, just a humble spirit and a love for what he’s doing, qualities that make him a joy to work with.

As for the cast of the show, these kids are clearly having a good time. They’re taking their roles as actors seriously, and they’re having fun doing so.

My point is, living in a small town doesn’t necessarily mean lack of opportunity for a jazz musician. Depending on the community, you may delightfully surprised at what you find. Hastings is fifteen miles down the road from where I live in the cow town of Caledonia. My home town being an outlier of Grand Rapids, I have access to a broader music scene that I can tap into. When it comes to playing jazz, some of the musicians I play with reside in Grand Rapids, but others, like me, live farther out–far enough to enjoy the countryside, yet close enough to be a vital part of the West Michigan music scene.

If you work hard at your instrument, and if personal growth as a musician is its own reward for you, then sooner or later you’ll connect with other capable players. You’ll make music. You may not make a living at it, but you’ll find opportunities to share your talent with appreciative ears.

Chromatic Couplets: Another Way of Unlocking Diminished and Augmented Scales

Have you had enough of the augmented scale yet? Hungry to get back to something nice and basic–a good, old-fashioned diminished scale, for instance?

How about the best of both worlds. The two exercises shown here (click image to enlarge) take you through two sets of chromatic couplets, each beginning with the note A. However, the first exercise is built on a diminished scale while the second is based on an augmented scale.

While both scales are symmetrical scales, which implies ambiguity of tonal centers, let’s for the sake of convenience call the topmost scale a Bb whole-half diminished scale, and the bottom scale a Bb augmented scale. A quick glance will tell you that both exercises start on the leading tone of the scale, which also corresponds to an altered dominant chord that the scale works well with.

I love the ethereal, rather mystical sound of  chromatic couplets used in this fashion. The first half of each exercise emphasizes chordal structure; the second half, without adding any extra pitches, creates a more linear feel.

Remember, because each scale is symmetrical, it functions equally well with more than just one chord of the same quality. The first pattern, built on the diminished scale, will not only work with an A7b9, but also with C7b9, Eb7b9, and F#7b9. The second pattern is a good choice for A+7#9, C#+7#9, and F+7#9.

And with that, it’s time for me to wrap up this post and go practice what I’m preaching. For more exercises and articles of interest to jazz and improvising musicians, visit my jazz page.

Augmented Scale Triad Patterns

Judging from my blog stats, there seems to be a lot of interest in the augmented scale. I’m not surprised. It’s a fascinating scale, and I’ve personally been having a lot of fun as I continue to work at getting it into my fingers and my ears.

One of the interesting and colorful aspects of the augmented scale is the fact that it gives rise to both augmented triads and major triads in sequential order. In this post, you’ll find three exercises that focus on augmented triads. However, the last one also hints at the major triads contained in the augmented scale. Click on the images to enlarge them to readable size.

As always, take each pattern up and down through the full range of your instrument. Other than that, the exercises are fairly self-explanatory, so I won’t say more, other than practice hard and have fun!

Oh, yeah…and make sure, if you haven’t done so, to check out my jazz page featuring other exercises and articles of interest to saxophonists and improvising musicians.

Moderate El Nino Firmly Entrenched through the Winter

While a few skeptics will no doubt persist, it now appears certain that the present, moderate El Nino will stay with us through the winter, and possibly even strengthen. Here is what the Climate Prediction Center has to say in its November 23 update:

•  During the last four weeks, positive equatorial SST [sea surface temperature] anomalies persisted across the central and eastern Pacific Ocean.

•  During the last 30 days, equatorial SST anomalies increased in some regions across the eastern half of the Pacific.

•  Nearly all ENSO models indicate El Niño will continue through the Northern Hemisphere winter 2009-10. The models disagree on the eventual strength of El Niño, but a majority indicate at least a moderate strength El Niño (greater than +1.0°C) through December-January-February 2009-10.

•  A majority of ENSO models indicate El Niño will continue through March-April-May 2010.

All of the above adds up to the fact that the western Great Lakes region is in for a mild winter. Those of us in Michigan who remember last year’s 200-inch snowfall and bone-freezing cold will welcome the above-average temperatures and below-average precipitation.

The South will also be seeing relief, albeit in a different but no less welcome form. Average to cooler temperatures and above-average precipitation will bring relief to at least some of the areas blasted by last year’s severe drought. Texas looks to be a major beneficiary.

The plenitude of rainfall in store for the southern Gulf Coast and Texas suggests that whatever concerns we may face during next year’s storm season, moisture won’t be one of them. Particularly after last May’s huge letdown, it’s nice to think that in 2010 there ought to be plenty of gas to fuel the convective engine.

Of course, that’s still a long way off. Right now, the best we can do is cross our fingers and hope for no repeats of 2009’s death ridge. I have a hunch that this coming year will be a good one. But first we’ve got a winter to get through, and it’s nice to think this one won’t be as nasty as its predecessor.

New High-Resolution Level 3 Radar Coming in February

Last night Grand Rapids got its first snowfall, and this morning I switched the color tables on GR3 and GR2 to winter mode.

Ugh. I suppose that blue, pink, and purple are going to rule for the next four months. I much prefer plenty of yellow, orange, and red, at least when it comes to radar displays, but we’re at that time of year when those colors aren’t likely to be very meaningful, El Nino or no El Nino.

While switching color tables is relevant to me as a Michigan resident who’s bracing for the winter, it’s nothing compared to the changes coming down the pike for GR3 and other level 3 data users in February. Here’s a message that Gilbert Sebenste of Allisonhouse, a well-known private supplier of raw radar data, posted in the AH and Stormtrack forums:

We have just been informed by the National Weather Service that starting in February 2010, and lasting through April, 2010…the National Weather Service will add higher resolution Level3 radar data products, replacing quite a few of the ones you use right now. The legacy products will continue to be sent for 6 months after all of the replacement products have been added, and will be discontinued on December 1, 2010.

What it all means in a nutshell is this:

1. Resolution will increase
2. The number of reflectivity levels will increase to 256 (meaning you will need to have 256 colors in your color palette to display all the intensity levels)
3. The volume of the files will double, on average
4. The Level3 format will change
5. It will be completed by the end of March, 2010…with legacy products ending 12/1/2010.

Allisonhouse will be working closely with its software partners to provide a seamless as possible transition to the newer and better products upon receipt of transmission from the National Weather Service, and we will provide you with more information as it becomes available.

Wow. Now those, folks, are changes, and it looks like they’ll be here right in time for storm season 2010. High-res level 3–imagine that! My one issue with level 3 has been its coarseness, but that problem is about to be solved. Within a few short months, level 3 data will be coming to us with the same finely shaded resolution as high-res level 2 while remaining a usable product in the field, which is what GR3 is designed for.

Of course, no chaser is going to love the idea of doubling the file sizes. But the improvements look to be awesome, and will give us much more detailed images of storms.

Other Changes on the Way

.

Exciting as the rapidly approaching implementation of high-res level 3 data is, it’s not the only significant development on the horizon. Next year will also see a major phasing-in of dual-pole radar to WSR-88D stations throughout the country. And in the private sector, Andrew Revering of Convective Development, Inc., is working on a huge upgrade for F5 Data forecasting software.

In summary, the technical/informational side of storm chasing will be seeing some significant advancements in the coming year. However many of those improvements are ready for next spring’s severe weather season, let’s just hope that the storms themselves put in a decent appearance.

Storm Chasing Musicians

When I started the Stormhorn blog two years ago, I envisioned two distinct readerships: storm chasers and musicians. Knowing nothing about blogging, I naively figured I could reach both audiences. I mean, what the heck, why not?

Amazingly, it seems to be working. The whole world may not be flocking to Stormhorn.com, but enough of you are finding your way here, and I’m encouraged to see the numbers steadily growing. Maybe that’s because musicians and storm chasers possess some important traits in common: a penchant for the unusual; a passion to excel; a thirst for personal involvement with something that is intense and deep; a fascination with how and why things work; a high degree of commitment and self-motivation; and a love of beauty.

For some of you, the focus is music. For others, it’s storm chasing. But both pursuits are fascinating and rewarding, and I’ve felt from the start that there’s a connection between them, and plenty of crossover appeal.

In fact, a good number of you bridge both worlds. In a recent thread in Stormtrack’s Bar & Grill (sorry, no link to the thread–B&G is a “members only” section), fellow chaser Wes Carter posed the question, “Who plays musical instruments?”

A fair number of you do, it turns out, including at least one who earns his living at music. That would be Huntsville, Alabama, blues man Dave Gallaher. Both as a solo act and with his trio, “Microwave Dave and the Nukes,” and also as a disk jockey for his twice-a-week radio broadcast, “Talkin’ the Blues,” Dave has made an impressive mark regionally, nationally, and internationally. A musician doesn’t accomplish something like that without paying some serious dues; it takes not only world-class skill, but also great crowd appeal and tremendous perseverance. You really want to check out Dave’s website.

Then there’s Brandon Goforth. While these days I’ve been hesitant to post YouTube links due to their unpredictable shelf life, I’d be remiss not to steer you toward this link featuring Brandon’s rock guitar artistry.The guy can play.

Dave and Brandon are just two stellar examples of people who are both musicians and storm chasers. There are plenty more. Maybe you’re one of them. Do you consider yourself primarily a musician who chases storms, or would you call yourself a storm chaser who plays music? Or are you, like me, so passionate about both pursuits that the question is irrelevant? Regardless, there’s an interplay between the two disciplines which suggests active minds with large appetites for life and learning.

By the way, I’m never without my saxophone. I take it with me wherever I go, and that includes out to the plains when I’m chasing storms. Some chasers toss a football while waiting for initiation; I practice my sax. So to my fellow chasers who play an instrument (most likely guitar): if we cross paths and you’ve got your axe with you, we just may have the makings of an impromptu Great Plains jam session.

Keep your eyes open for me this coming spring. And if any of you happen to know of a good jazz venue in Tornado Alley, please let me know. Such places are hard to come by out west.
