Weekend Low Still Trending North

Morning and afternoon runs continued to show a more northerly track with our weekend low passing through northern Illinois Saturday afternoon and into Michigan by Saturday night.  If this trend continues, the chances of a significant snow across the Stateline would likely be reduced as warm air would keep a mix going early Saturday before changing to snow by Saturday evening.  The top image on the left shows the probability for at least four inches of snow while the bottom is for eight.  With this more northerly track, if this were to actually pan out, the heavy snow would be shifted through Wisconsin.  A slight deviation further to the south, however, would bring that heavy snow band down.  Winter Storm Watches have basically been issued for the entire state of Wisconsin, northern Iowa and southern Minnesota in anticipation for this more northerly track.  If the next couple model runs continue to come in with this northerly track, we'll trend down our snowfall totals and increase the chance of rain at the onset Saturday afternoon.
