Blizzard and Severe Storms Continue

December 20, 2012; 10:21 AM ET


1. The map below shows the snowfall from the HRRR model total snowfall through tonight. It does not take into account the lake-effect snow that will start tomorrow and last into Saturday.

2. Chicago is done with the bulk of the rain, but as the day progresses, the band west of Chicago should move in giving them a few inches of snow, especially north and west of the city.

3. Severe weather will remain across the Southeast today. I put an intense area across the Florida Panhandle and southern Alabama where a wedge of 60s to 70 dew point air has come north into that area. Most of the storms that I have seen this morning have had a weak rotation in them, but enough rotation to produce small, quick hitting tornadoes.

4. High winds will continue around the storm with gusts over 40 mph. Winds will calm down from southwest to northeast in the Plains today, but they will remain gusty across the Great Lakes Friday.

5. Lake snow and lake blizzards will get started by Friday morning off lakes Michigan and Superior, and by Friday night off lakes Erie and Ontario. Heavy bands of snow will even propagate into the Appalachians from Pennsylvania to West Virginia Friday into Saturday with amounts up to 6-10 inches.
