In the last hour, we've gotten another 25 mm of snow, with more on the way:
The initial stages of snowfall will come in bands this morning (check weather radar pic above) – moving from southwest to northeast. A few locations are observing a mix of snow and sleet and this will continue on and off for the next couple hours, but the precipitation will change over to all snow and increase in intensity late morning and afternoon. Homewood in Cook County reported an inch of snow in an hour with a mix of sleet. Below is the 9AM CST visibility map depicting the variability of snowfall across the Chicago area.
A band of light to moderate snow is moving though the area this morning and could drop a quick inch of snow in many locations. This band will end and there will be a break before the main area of heavy snow arrives later this morning. Winter storm warnings are in effect and snowfall totals of 100-200 mm are expected before the system moves out this evening.
The original prediction called for just 25-50 mm; apparently the snow got excited.
Meteorological winter ends in just 11 days. Actual winter may last longer.
