Light Snow Friday Evening

Light snow will kick off the start of the weekend, but any accumulating snow for the Stateline looks to remain low.  Low pressure moving in from the west Friday will lift into the Upper Midwest Friday afternoon and evening.  Accumulating snow will develop ahead of the low during the afternoon, impacting mostly northern Iowa, Minnesota and Wisconsin.  The best chance for snow in the Stateline will occur north of Highway 20 during the late afternoon and evening.

The snow won't be much and shouldn't cause many issues heading into Friday night or Saturday morning.  A stronger low pressure system will develop over the southern Plains Saturday afternoon and evening, moving south of Illinois during the day Sunday.  An abundance of moisture will bring heavy rain and thunderstorms along the southern states, but snow stretching from parts of the Plains into central Illinois.  Looks like most of northern Illinois and southern Wisconsin will be on the northern edge of the snow Sunday, with only a few light snow showers likely - especially south of Rockford.

Following the low an extremely cold air mass (for the beginning of March) will settle south into much of the country.  This will push temperatures nearly 20-25 degrees below average for the start of the week.
