An area of heavy, wet snow is expected to fall across portions of northwest and central Illinois, and portions of west central Indiana today. he snow will result in travel impacts, and create difficult conditions for plowing and shoveling. The northern gradient in snowfall will be very narrow, with snowfall amounts differing by several inches over as little as 20 miles. In addition to the snow, easterly winds will gust to 35 mph late tonight through Saturday. This wind will allow the wet snow to accumulate efficiently on elevated surfaces, possibly resulting in broken tree limbs and isolated power outages. Snow will end from north to south late this afternoon and early this evening.
Winter weather tonight and Saturday will give way to temperatures more typical for late March by early next week. With the warmer weather will come periods of rain and possibly a few thunderstorms.
