The 2/6/2007 storm was mentioned in the storm thread so I thought I'd post more here. That is one of my favorite moderate sized snow events mainly due to how cold it was. It was like 5 degrees here when the snow started and we had a few hour period of heavy snow with temps hovering either side of 10 degrees. Very few times I have seen it snow that hard at those temps. There was a very sharp thermal gradient with that event...IIRC St. Louis got into the 40's.

Surface plot from 17z that day:

Feb 11 2003. A very impressive and fast moving band of heavy thundersnow along a cold front swept all across Iowa and slammed northern and central Illinois. This line almost resembled a line of severe thunderstorms along a cold front in the summer. I remember watching it roll in. There was even a gust front along the leading edge, with a thick bank of low clouds. The heavy snow rolled in like a wall of white. I remember the visibility dropped from a perfect 10 miles down to near zero in less than a minute. Northwest winds gusted close to 60mph as well. It was a truly amazing event, and I've never seen anything like it before or since.

The heaviest snow only lasted about 5 minutes, but it turned the ground white in that short amount of time. IIRC we picked up over a half inch in a little over 5 minutes. One can only imagine how much snow would have piled up if a snow rate like that were to continue for any length of time.

The NWS in Lincoln Illinois actually issued severe thunderstorm warnings for this snow squall.

I remember this very well. I used to have the text for those warnings but not sure I have it anymore.

That is some serious snow bands. Some sort of convection played a role there; 3-4" per hour would seem to justify that. It would be interesting to see what the forecast in 1982 was like.

The forecast for that storm was 3-5" or around there. As it turned out, there was around a 5 hour period of thundersnow at Lambert. My father, who had happened to be out in that storm, said there was plenty of thunder and lightning with the storm, somewhat akin to what you would expect with a springtime thunderstorm, as well as ridiculous snowfall rates.

Here's a link to a paper by the late Dr. Moore on the storm:

Dec. 2000.....:wub: Only one of two times that I remember being under a blizzard warning the other of course being Jan 99. I'm pretty sure I got around 15 inches in that event.

Does anyone know the details regarding this storm? It's one of my fondest childhood winter memories however I really have no idea what the setup was like or anything except that it was pretty amazing imby.

I loved that storm 15 inches down where I was at in Roseville.

Btw I love how we all of a sudden have a bunch of SEMI posters :)

Thanks, I will give that a look. I love Dr. Moore, he was a great meteorologist. Sad he passed away too early.

Yeah I remember looking at Bufkit soundings a couple days beforehand and it showing like 20" or something crazy.

There was a 6z run of the GFS about 3 days out that dropped about a foot here. Of course I stupidly started to get a little excited against my better judgement. Ended up with nothing.

We were under a watch 2, and plus had like a foot of snow on the ground already. I was so excited, thought we would have 2 feet of snow, yeah right.. .. BUT hey, snow does not like to fall on top of snow for some reason, at least around S/E Mi. LOL.. Unlike the Mid Atlantic last year. GEE.
