Patchy, dense fog lingered Thursday morning in Pinellas, Hillsborough and Pasco counties, though no fog advisory was issued.
Sea fog also covered coastal areas and might stick around into the early afternoon.
The rest of the afternoon will be partly sunny, with temperatures in the 70s. Wind will keep coastal areas in the 60s.
"Like the past couple of afternoons, it's going to be pleasant," said Juli Marquez, Bay News 9 meteorologist.
Thursday night is expected to bring rain and thunderstorms that could last through Friday.
