Tampa’s Friday forecast starts with clear skies and temperatures around 75 degrees, followed by a high near 90. Scattered showers and thunderstorms become possible after 2 p.m.

The National Weather Service Tampa Bay Ruskin office puts Friday’s rain chance at 40%, with showers and thunderstorms possible south of Interstate 4. Lightning and brief downpours could still disrupt late-day outdoor plans.

Saturday should remain mostly sunny through the morning, with storms possible after 2 p.m., a high near 90 and a 70% rain chance. That matches the 70% Saturday outlook in Thursday's Hoodline forecast, but the weekend pattern could become wetter Saturday night.

Sunday Brings Unsettled Weather

Sunday looks unsettled, with numerous to widespread thunderstorms and a high near 90. The unsettled pattern is forecast to continue into early next week, with storms possible Monday, while the outlook for Tuesday through Thursday remains unspecified.

Flooding and Heat Safety

Heavy rain can create localized flooding in addition to short-lived travel disruptions. According to the City of Tampa, localized flooding caused by rainy-season thunderstorms and tropical storms is the city’s most frequent type of flooding. The city recommends using FEMA Flood Insurance Rate Maps, which illustrate flood hazards and help assess a property’s flood risk. Hillsborough County defines a heat advisory as a heat index of 108 degrees or greater and advises residents during heat advisories to stay indoors, stay hydrated and check on vulnerable neighbors and loved ones.

No land-based watches, warnings or advisories are listed for Tampa, but a Small Craft Advisory is in effect for Tampa Bay and nearby Gulf waters through 2 a.m. Friday. People heading outside Friday or over the weekend should keep an indoor backup available, particularly during afternoon storms, when lightning, sudden downpours and locally gusty winds can develop quickly.
