Everything continues to be going as planned with regard to our light snow event that is expected across the northern half of Illinois later this evening and into Monday morning. Our shortwave will be moving across the Dakotas early this afternoon and will continue in our direction over the next 12 hours or so as it heads ESE into the Midwest by late tonight and early tomorrow morning, seen in the loop below.
Even though we are now into April, this will be a minor event for most areas with accumulations up to one inch expected, with isolated amounts slightly higher possible, favoring a little further south across central Illinois.
Snow is falling to our west and northwest across portions of the Midwest, including the Dakotas and making its way into Iowa and Minnesota.
This area of snow will continue eastward in our direction during the afternoon hours, before moving into western Illinois during the later afternoon and early evening. Just after, snow will begin to overspread all of northern Illinois during the mid-evening hours.
Snow will wind down tomorrow morning across the area with high pressure building into the Midwest and a return to quiet and below normal temperatures for a couple of days ahead of a big warm up.
Our latest thinking on snowfall amounts later this afternoon through tomorrow morning
