We’ll keep this short and sweet today with the main things to focus on for this forecast period. 

First and foremost, rain chances. We’re going to see spotty precipitation overnight with the bulk of the rain existing along the cold front in the northern portions of the state. Still expect to see another 1-3″ of rainfall through Thursday morning. 

Cold front should begin to move through Tuesday night/Wednesday morning which will bring the heaviest rain potential. The potential for icing exists (mainly between I-70 and Mt. Vernon) Wednesday morning and Wednesday night but plenty of mitigating factors working against icing accumulations (initially warm surface, high rainfall rates, warm rain). We’ll keep an eye on potential icing in a more now-casting scenario once we determine if icing can overcome the mitigating factors mentioned above.

Thursday-Saturday should bring another chance of rain, this round should be focused south of I-70 with the heaviest amounts focused south of Mt. Vernon. Expecting an additional 2-4″ from this event as well for storm total rainfall through Saturday equating to 4-6″ with locally higher amounts possible.
