The Groundhog Day Blizzard of 2011

blizzard3-2011The cloud tops are up to 20,000 feet here in Caledonia, and about two minutes ago the first impressively bright flash of lightning lit the blizzard swirling around my apartment. Thundersnow! Rare, but  not unexpected tonight, and now that it has arrived, I’m continuing to see sporadic flickers of lightning. That initial one was a doozy, though, and all I can think is, Cool! How often does one get to hear thunder rumble through the teeth of a February blizzard?

Man, is it blowing out there!

All eyes have been on this winter storm for the past several days, watching it move from forecast models into reality. Nowcloud-tops-2011here it is, and it is a humdinger. Anywhere from a minimum of 12 up to 16 inches of snow is predicted to dump on our area, and south of us it only gets worse. Pink is the color that indicates heavy snowfall on my radar color table, and I don’t recall ever seeing such a large expanse of it covering my screen before. Between now and sometime tomorrow morning is when the heaviest snowfall is supposed to occur, and looking outside my window at the maelstrom swirling dimly out of the midnight sky, I see nothing to contradict that prognosis.

blizzard4-2011Ah! Another flash of lightning and another rumble of thunder! This is nice. Imagine that–me, an avowed snow grinch, enjoying a blizzard! But I have to say, this storm appears to be living up to all expectations. I honestly don’t recall that I’ve ever experienced thundersnow before, so I’m really pleased to be getting such a novel form of entertainment.

The three fairly recent radar grabs and the water vapor image on this page will give you an idea of what a truly wild evening this is. Click on the images to enlarge them. The first and third are basic winter reflectively images, with the latter offering a more zoomed-in look at southern Michigan. Look at all that pink! Interrogating a few of the deeper hues has given me reads of nearly 40 Dbz, and that’s nothing compared to elsewhere, and perhaps to what yet lies in store for us.

blizzard-2011-wvAs for the second screen, that shows cloud tops. The teal colored blobs indicate tops of 20,000 feet or greater, where thundersnow is likeliest to occur. And the fourth image depicting water vapor gives a macro view of what the entire system looks like as an immense entity sweeping eastward, with the dry slot punching upward into Illinois.

This may be one for the history books. I’m glad I stocked up on groceries, because I doubt I’ll be venturing out tomorrow. I doubt anyone will be. I’m certain that all the schools will be closed, and quite possibly many businesses as well. It will be a good day to hunker down and feel grateful for being indoors.

Zang! Another bright flash. I just got a phone call from my friend Brad Dawson, who lives down near Gun Lake. He tells me that a big towerblizzard6-2011500 feet from his house is getting continually struck. That has to be an experience, and from the looks of things, it’s apt to be one that continues through the night. Lacking any similar tall objects here, the lightning isn’t as constant, but it continues to flicker, and the storm itself is intensifying. What the heck–here’s one last image: a current radar scan. I just got a reading of 43.5 Dbz in one of the darker blobs of pink!

This is one howler of a winter storm system. But I’m done watching it for now. It’ll still be here in the morning. Time for me to hit the sack and enjoy the light show for a while before I fade out. Good night!

Late-Season Thunderstorms in Lower Michigan

Amazing as it seems on November 17, I just heard a rumble of thunder. It wasn’t the first today. Several hours ago, a small line of storms swept through southwest Michigan, dumping rain, producing occasional lightning, and prompting warnings of “strong storms in the area capable of producing pea-size hail.”

Taking the unexpected opportunity, I hopped in my Buick and headed down into Barry County, where the more intense cells were moving through. We’re not talking anything major here–tops maybe scraped up to 20,000 feet–but this time of year I’ll take whatever I can get in the way of convection. Not being aware of any lifting mechanism in lower Michigan, I’m a bit mystified what it is that has been firing off the storms. The RUC soundings for 20Zand prior shows weak CAPE in the neighborhood of 200 J/kg with light winds at all levels. With surface temps peaking at 52 degrees, maybe that minimal instability has been enough to support some modest updrafts.

Whatever the case, it has been nice to get these late-season popcorn cells. They’re dying off now that daytime heating is dwindling, but they’ve made for a bit of serendipitous fun throughout the afternoon. And now I suppose we return to our regularly scheduled program of November drabness. I’m looking forward to watching Storm Chasers tonight and reliving the wild drama of May 22 in South Dakota.
