JACKSONVILLE, Fla. – A strong cold front is moving west to east from the lower Mississippi Valley and will reach our area on Sunday. Our area has been placed in a risk level 2 out of 5 for seeing severe weather during the day.
Ahead of the front, Sunday will start off windy and with unusually warm conditions during the day. South winds will run 15–25 mph, with gusts up to 35-45 mph. As a result, a Wind Advisory has been issued for areas along and west of the St. Johns River.
By early to mid-afternoon, beginning after 3 p.m., a main line of storms is expected to move into western areas and push east through the evening. Some scattered storms could pop up ahead of the main line.
As the storms organize, a few could produce damaging wind gusts (60-70mph), and there’s a small chance of an isolated tornado, especially from inland Northeast Florida into inland Southeast Georgia. This could bring down trees and powerlines.
Frequent lightning will be possible in any storm. Factoring in how dry it has been, this could ignite additional fires.
The threat for flooding remains low due to the fast movement of the front.
The main squall line will weaken as it moves east Sunday night. While a severe storm can’t be ruled out early in the evening, the threat should decrease after about 8–9 p.m. as the atmosphere stabilizes and the cold front pushes through.
Rain chances will drop off overnight, and cooler air will filter in behind the front, with lows falling into the 50s.
