The Next 4 Days...

Short Term: All is quiet across northern Illinois this afternoon but attention is to our west and southwest as a storm system is slowly organizing with widespread precipitation already ongoing across the plains an into portions of the Midwest. As broad warm air advection and insentropic lift get going later tonight, expect a gradual increase in snow from west to east near or after the midnight hour. Light snow should continue into tomorrow morning and afternoon with amounts of 1-2" possible from this first wave of snow. Beyond tomorrow evening, model guidance differs somewhat on the amount of warm air aloft that is advected in on the eastern side of the deepening upper level low. For that reason, differences remain on if we stay all snow throughout this event or see a period of mixed precipitation or plain rain on Friday. If we do, expect precipitation to go back over to all snow Friday evening and this looks to be our best chance for better snow accumulations, potentially in the 1-3" range from Friday evening into Saturday morning making for a long drawn out storm total of 2-5". Now, with marginal surface temperatures and mostly lighter snow rates, it is entirely possible that roadways aren't affected much at all and the accumulations will be seen on grassy and elevated surfaces. Could roadways become partially snow covered? Yes, but this is not going to be like last Friday night when we got all over or snow in a short amount of time with heavy snowfall rates.

Beyond 4 Days...

Long Term: Beyond this system, high pressure will build into the region on the backside of the departing area of low pressure and make a for a quiet end of the weekend on Sunday with slightly above normal temperatures. Expect this to then continue into at least Tuesday morning before we could be in store for another storm system to impact our area. Much like this current incoming system, the one next week will be working with marginally cold air both at the surface and aloft so we it entirely possible this is a system that produces rain and mixed precipitation for us Tuesday night and much of Wednesday as it slowly moves through our region.
