Big Daddy Category: 3

I don’t have a lot of changes to what I mentioned yesterday. The thrust of the heavy snow will be into two areas. One area in the Midwest and the area from the Ohio Valley into the Mid-Atlantic. Both areas should see 4-6 inches with maybe some local 8 inch amounts.

The models still continue to show a split in the precipitation with the convective thrust into the Ohio Valley and Mid-Atlantic. While that area will see convective snowfall and may see rates of 1-3 inches per hour for a few hours, the snow will change quickly over to a mix of snow, sleet and freezing rain then maybe just rain. So the excitement of heavy snow only occurs Wednesday afternoon and evening for a few hours.  Roads during rush hour(s) will probably be messy.

Midwest gets most of the tonight and Wednesday morning prior to the storm splitting.

Overall this is a big storm in regards to the coverage of the snow. I posted the various snow maps below and I am still leaning toward the ICON model as my model of choice.

Above is the HRRR model of the surface and radar pattern through Wednesday Midday.
