Snow, ice and potentially severe weather are slated to hit parts of the Midwest this week, but there will likely be a sharp cut-off line for snow when the system hits.

The winter weather advisory takes effect at 6 a.m. Thursday. Forecasters say 2-4 inches of snow could fall, with some sleet mixed in at the outset of the storm.

A storm system will bring a period of light snow to Central Illinois Thursday night and Friday morning. While accumulations are expected to be on the light side, there should be enough snow to impact the Friday morning commute.
