Over the next 24 hours, our emphasis will be on two different types of weather: severe storms (possible Tuesday afternoon) and a winter storm (possible Wednesday). A third threat will be from torrential rain…the first of which could happen with a bout of thunderstorms late Monday night. The model range for rainfall is between 1.32″ and 2.85″. With the ground frozen, we may have some flooding issues, especially in rural areas where rain will pool in low-lying areas and fields. Click here to read more on our severe threat.
While there is disagreement in the models on when and if the rain will change to snow Tuesday night, a few models have locked onto a very snowy solution late Tuesday night through midday Wednesday. Very possible we could be tracking severe storms Tuesday evening with a blinding snowstorm occurring before the sun comes up Wednesday. 
Our Futuretrack model (shown here) is putting down more than a half foot Tuesday night into Wednesday.
Having said that, if the models continue to advertise snowfall potential for Wednesday, we may have Severe Thunderstorm/Tornado Watches at the same time as Winter Storm Watches for a time on Tuesday!
Bottom line: saying this weather is a roller coaster would be an understatement. Please have a way to receive weather watches and warnings, and check back on the blog as we update frequently! -Eric
