After another spectacular weekend with sun and mild temps, we're heading into one more pullback toward winter conditions. 

Lake and McHenry counties are under a Winter Storm Warning from tonight through Tuesday morning. ~2" along the Cook County border to up to 6" along the Wisconsin border is the most likely scenario for now. But given that this is a strong but small and fast-moving storm, with lots of warm air at the ground, it wouldn't take much to alter this forecast. 

South of Lake/McHenry, DuPage, Cook and the city of Chicago are under an advisory for sleet and snow. Rain or mix tonight should transition to some freezing rain and eventually light snow tomorrow morning. Accumulations should be fairly light. Given how warm the ground is I would hope the roads will stay in decent shape, but some impact on the morning commute cannot be ruled out. 

The rest of the work week looks dry with below-average high temperatures in the 30s. The weekend will mark the beginning of a warm-up and it looks decent in its own right. And although we're still too far away to have much precision, the signals are in place for a major early-season warm spell beyond the weekend. The early to middle portion of next week (March 8-10) could well see temps in the 60s and 70s. As noted in one model below, even an 80 is not impossible, which would be a record for the date.
