During this timeframe we could easily see some bands set up that dump over an inch per hour. Some light snow could hang around through lunchtime on Saturday. The graphic to the left is from the GFS model and it's estimating approximately 0.25-0.30" of liquid to fall between midnight and noon Saturday. The snow to liquid ratio could be 15:1 or even as high as 20:1 due to the cold conditions in the atmosphere, which means the snow should fluff up quite efficiently.Original Post = The Winter Storm Watch that was previously out for northern Illinois was upgraded this morning to a Winter Storm Warning. This means that the potentially heavy snow situation is looking quite likely. It will run from this evening through Saturday afternoon. The Milwaukee National Weather Service office hasn't decided yet on what it wants to do with the watch for southern Wisconsin. It could be upgraded to a warning or downgraded to an advisory. The 3-6" snow slot should still cover the majority of the Stateline viewing area. The lower end of the spectrum appears to align in the counties of Green, Rock, and Walworth. The higher end of that spectrum could cover a large chunk of northern Illinois. There is still even the possibility that a narrow band of slightly heavier snow could form somewhere near I-88.
I will have further analysis when the midday models come out between 10-11am. -ADAM

i know people that need to make a trip to Peoria tomorrow morning (early) what will the possible conditions be?
I have to work at 7am tomorrow morning, based on these forecasts, I am guessing I will probably be driving in some pretty heavy snow. Am I right adam. Plus do you think the snow will be starting at 9pm, or will it be after that.
Road conditions will be pretty rough in the morning. The people heading to Peoria can at least take heart in the fact that the interstates are the first roads plowed in any snow storm and will be best options to take.
Based on that model you just put up, would the 6+ area be moved up to us or is it still likely to be in the I-88 corridor.
how far south will this snow be falling? will they be driving out of it? maybe 39 is the best bet to do for the most part. thank you very much and i will be watching your forcasts.
Uh oh. Looks like eric bumped us up a little bit. Cant wait.
Did anyone notice anything wierd about the 12-hr precip gif that Adam posted Friday morning?
Call me nuts, but doesn't that precip pattern in the middle of the country look kind of like the silhouette (sp?) of South America? If you squint just the right way, the precip off to the right almost looks like stylized silhouettes of Africa and Europe and to the left almost like the coast of China.
Okay, maybe I've fallen off the deep end...
Oh my! You've got a good eye. I see it as well. I may have to save this one for posterity's sake. :)
