The snow from Tuesday night came to an end early Wednesday morning with roughly 1-4 inches falling across far northern Illinois, centered along the Highway 20 corridor and into southern Wisconsin. Areas to the south experienced little to no snow accumulation.
While there is a little break in the wintry weather Wednesday afternoon, snow showers will soon return during the evening with the first of two, Arctic cold fronts that are forecast to sweep across the Midwest and Great Lakes. Light snow has been falling out west over Iowa and Minnesota ahead of a strong cold front that'll move across northern Illinois and southern Wisconsin later this evening. As it moves towards the Mississippi River, we should start to see the beginning of the light snow move in from west to east around 5pm, exiting the viewing area around 9pm.
The snow won't be much, generally around a half an inch to an inch, but an increasing west wind behind the front will cause what snow is coming down, and whatever snow is already on the ground, to blow and drift. In open and rural areas, the blowing and drifting will become rather significant with wind gusts near 45 mph in some locations.
In anticipation of the incoming snow and wind a WINTER WEATHER ADVISORY has been issued for the following counties beginning at 5pm: Jo Daviess, Stephenson, and Carroll in northwest Illinois and Green in southwest Wisconsin. While an advisory has not been issued area-wide, blowing and drifting snow will be an issue all across northern Illinois and southern Wisconsin, even in locations that didn't receive much snow from Tuesday night.
This will cause hazardous travel through the late evening, with some of those impacts lasting into Thursday morning - even though the winds won't be as strong. North/south roads will be impacted the greatest with the blowing and drifting due to the west wind. Please travel with caution later this evening as road conditions will deteriorate once the snow moves in and winds pick up.
