This is the short range forecaster for The Weather Centre here to tell you some new inputs from the 18z model run.
*Showing heaviest snow in WI, North IL.
*Band of heavy snow in Upper MW.
*Other heavy snow in N. IL, WI, IA.
Below is HPC current thinking.
Accuweather is favoring 4-8 inches.
Based on all that info, I believe things are clearing up so that a SnowMap may be issued later on tonight.
