| Area Forecast Discussion National Weather Service Tampa Bay Ruskin FL 250pm EDT Wednesday July 15 2026 Issued at 250pm EDT Wednesday July 15 2026 A rather dry northwest flow across the region this afternoon with limited convective coverage expected, and mainly over the interior. Later tonight into Thursday morning some additional moisture will move into the area leading to scattered showers and a few thunderstorms over the northeast gulf waters moving onshore into the Nature Coast and Tampa Bay area. This scattered convection will continue to develop and move southeast across the region Thursday afternoon and evening. For Friday through the weekend an upper level trough will deepen along the eastern U.S. seaboard into the eastern gulf with an area of low pressure potentially developing over the eastern gulf and moving across the region. No matter what though, this setup will bring increasing moisture and much higher rain chances to the area. This system moves away from Florida early next week with rain chances gradually diminishing by midweek. Marine Issued at 250pm EDT Wednesday July 15 2026 West to northwest flow will persist over the eastern Gulf waters through Friday, then shift to southwesterly over the weekend. Isolated to scattered showers and thunderstorms will continue through Thursday, then more numerous showers and thunderstorms are expected Friday through the weekend. The flow is forecast to increase late in the week through the weekend with Small Craft Advisory conditions possible Sunday and Sunday night. Fire Weather Issued at 250pm EDT Wednesday July 15 2026 Weak high pressure will remain over the region keeping the warm and humid summertime conditions in place with isolated to scattered showers and thunderstorms through Thursday. Deeper moisture and more numerous convection is expected for Friday through the weekend. Gusty erratic winds and frequent lightning possible with the thunderstorms.
