Strong to Severe Storms Today Followed By Much Colder Weather

1. Severe Storms Expected Today


Thunderstorms have developed along and ahead of a cold front to the west of the area this morning. Some have already been severe in the FL Panhandle and Southeast AL. The front will cross the region from west to east today with the severe threat also spreading east. 
  • Main hazards: Damaging winds and isolated tornadoes with areas of tree and power line damage. Some structural damage possible in tornadoes. 
2. Turning Much Colder Beginning Tonight


Tonight will feature steadily falling temperatures with northwest winds around 10-15 MPH. The arrival of the Arctic air mass should produce a light freeze north and west of a Valdosta to Panama City line. Wind chills by daybreak Tuesday should range from around 15 degrees in Southeast AL to the lower 30s over the eastern Florida Big Bend. 


Although Tuesday should be sunny, it will be chilly, especially for November. High temperatures in the 40s are expected in most locations. The all time record for coldest high temp at Tallahassee on this date is 49, and the forecast calls for a high of 50. Continued winds will make wind chill readings even colder. 


High pressure settling into the area should create clear skies and light or calm winds on Tuesday Night. This should allow temperatures to plummet with a hard freeze watch now in effect across the entire area. Record lows will be possible, and most areas should spend over 10 hours below freezing.
