From the beginning of this week, a surface low pressure system is expected to form on the leeward side of the Rockies, over the Great Plains. Upper air winds will direct the surface system to the Southeast US on Tuesday, clipping the Gulf of Mexico before pushing Northeast towards the Atlantic on Wednesday. The central/northern Florida region will be on the northeast side of the low, likely along the warm front. Thunderstorm capability along the front will be fairly high, with CAPE values expected over 1000 J/kg during Wednesday afternoon. In fact, the NWS Storm Prediction Center has the area within a marginal chance for severe weather for both Tuesday and Wednesday, as seen in the maps below.
For the weekend, a low pressure system centered over the Great Lakes will have a cold front extending southward into the Southeast US, though it will be weaker than the front passing through mid-week. The front will bring warmer overnight temperatures as winds shift to the South/Southwest along with another slight chance for scattered showers during the afternoon.
