8:00pm Update: Still seeing plenty of snow on the radar. You'll notice the heaviest snow runs from the Rockford area into Walworth County. There's a reason for that.


Winds are turning out of the north and east, which means lake effect snow that is pushing into the area. While this won't add major amounts of snow onto our current totals, it will keep things messy as long as winds keep up through the night.


7:00pm Update: Snow showers are slowly starting to lighten, especially to the west of Rockford. Snow will continue through this evening before ending after midnight.

Our Winter Storm Warning has been dropped for Jo Daviess, Stephenson, Carroll, and Whiteside counties. The rest of the viewing area will continue to be under the Warning through this evening due to some lingering snow and winds that will cause blowing, drifting, and limited visibilities.


Here's your impact forecast heading into the morning. Snow will end first (after midnight), followed by gusty winds, but a few messy spots will be possible in the morning as slushy spots freeze overnight.

4:00pm Update: Snow continues to fall across the Stateline. The latest radar still shows pockets of moderate snow from Rockford down into DeKalb, with lighter snow to our west. Snow will slowly lighten through the evening, but increasing winds will cause blowing, drifting, and limited visibilities. A Winter Storm Warning continues through this evening for the entire Stateline due to the snow and wind.





 1:30 pm Update: Back edge of the heaviest snow extends from the Quad Cities northwest to Dubuque, IA with a few light snow showers back in central Iowa.  As low pressure and an inverted trough shift south and east there may be a few rounds of heavier snow that develop across north-central and northeast Illinois until ending by tonight.  So far, snow totals between 5"-7" have fallen and we'll likely pick up another 2"-3" before all said and done.  Winds are already beginning to shift around to the north and will eventually turn north/northwest this evening and increase some in intensity.  Still looks like we could see some blowing and drifting snow through tonight.


Winter Storm Warnings remain in effect through Tuesday night.  Moderate to heavy snow will continue through the remainder of the morning and afternoon.  Within the heavier snow bands snowfall rates of half an inch to one inch per hour are possible.  So far, snow totals between 3"-4" have been reported with overall snow amounts expected to remain between 6"-10".  Winds are also going to increase late this afternoon and evening from the north and northwest which will cause blowing and drifting snow by this evening.
