As an upper disturbance continues pushing east, moisture from the Gulf of Mexico and cold air from the north are mixing to make Tuesday a nasty day.
Some wrap-around moisture on the west side of the upper low is the only chance for some frozen precipitation in the form of sleet. It's possible, but not very likely, in the northern Florida parishes late . Temperatures will remain in the 40's throughout the day and a cold night tonight.
Behind the upper disturbance, a deepening upper trough out of Canada is bringing the coldest air of the season thus far toward the Gulf coast!
Wednesday morning lows should drop into the low 30's north and west. A hard freeze is expected Thanksgiving morning on the North shore as temperatures reach the low and mid 20's. A light freeze is expected for the south shore.
