Major Midwest Blizzard Underway

A large winter storm has hit the Midwest with 26" of snow (Winona, MN) and wind gusts up to 62 mph (Grand Island, NE). At Rochester, MN, 15" of snow broke the record of 5.5" set in 1893 for December 11th, and the record for daily snowfall for December. The old record was 10.3" on December 25th, 1955. The snow even collapsed the Minneapolis Metrodome. The storm total reported at Minneapolis/St Paul international Airport was 17.1".

Last night, blizzard warnings (red) went from Nebraska and South Dakota to Michigan:
Winter storm warnings are in pink, winter weather advisories in purple, and wind chill advisories in light blue. Because of arctic air surging southward behind this storm, the current map again has hard freeze warnings (dark blue) along the Gulf Coast, freeze warnings (light blue) for southern Texas and New Orleans, wind chill advisories for central Florida, and wind chill watches for southern Florida.
In Florida, 6Z GFS MOS has low temperatures for Tuesday morning at 18 for Gainesville, 24 for Daytona Beach, 37 for Miami, and 53 for Key West.
