400pm EDT Wednesday May 5 2021

High pressure ridging west from the Atlantic Ocean across south Florida will maintain the warm and humid conditions through Thursday with southwest to west winds persisting. A cool front will approach from the northwest Thursday and move across the region Thursday night and early Friday. A few showers and thunderstorms will be possible late tonight near the coast from the Tampa Bay area northward as the remains of the current convection off the Florida panhandle move toward our area. Then during Thursday and Thursday night the westerly flow will take the best chance of convection east into the eastern half of the Florida peninsula, but a few showers and thunderstorms will remain possible in our area, especially along and just ahead of the boundary. For Friday and Saturday, high pressure will build in from the northwest ushering in a refreshingly cooler and much drier airmass. Early next week the high will slide east out into the Atlantic Ocean with a more southeast to south flow returning along with the heat and humidity and isolated to scattered afternoon convection over mainly the interior each day.

High pressure will slide south ahead of an approaching cold front that will push into the waters Thursday and Thursday night, with showers and storms possible. Winds will increase to near exercise caution levels behind the front Thursday night and Friday, before high pressure builds back into the waters during the weekend.

Fire Weather
Relative humidity values will remain above critical levels through Thursday, then much drier air will overspread the region Friday and Saturday with several hours of relative humidity below 35 percent possible, especially away from the gulf coast. It will also be rather breezy each afternoon through Friday with northwest winds Friday afternoon increasing to around 15 mph. Therefore, no red flag conditions are anticipated through Thursday, but could be close on Friday afternoon.
