A more widespread heavy rainfall event will unfold Tuesday afternoon through Wednesday ahead of a cold front, with an extended period of heavy rainfall expected across inland SE Georgia and the Suwannee River Valley of NE Florida. There is also the potential for a few strong to severe storms during this period.
Rainfall will gradually diminish west to east Wednesday night trailing a cold frontal passage. Cooler and drier conditions are expected by Thursday, Christmas day.
Rainfall:
At this time, widespread flooding is not a major concern given that it has almost been a month since significant rainfall fell across most locations. Waves of heavy rainfall are expected during two distinct periods. The first wave of moderate rainfall will continue to lift northward today, with a break in persistent widespread rainfall tonight and early Tuesday morning. The second wave of moderate to heavy rainfall is expected late Tuesday through Wednesday ahead of cold front.
A few strong to severe storms are possible Tuesday afternoon through Wednesday across northeast Florida. A few strong storms may impact southeast Georgia Tuesday Night, but instability will be more limited over this area. There will be a variety of strong to severe storms hazards including gusty winds of 40-60 mph, hail, and the potential for brief tornadoes, especially across the Suwannee River Valley Tuesday night and early Wednesday.
