| Area Forecast Discussion National Weather Service Tampa Bay Ruskin FL 306am EDT Fri Mar 13 2026 Issued at 301am EDT Fri Mar 13 2026 The front that pushed through the area yesterday remains stalled over south Florida and will likely linger over the weekend. Though drier air has begun to filter in over the northern portions of the forecast area, deep moisture will remain over the southern portion thanks to the stalled front. The deep moisture with diurnal heating could lead to scattered showers and isolated storms over SWFL. Though morning temperatures will feel a bit cooler, afternoon temperatures will reach into the mid to upper 80s. Rain chances will continue to increase for more of the forecast area as the stalled front shifts north and a warm front moves in from the south. A second cold front will move through Monday into Tuesday. Unlike the current front that brought little change in temperature, this next front will usher in much cooler air. Low temperatures will drop back into the 40s and 50s through the end of next week. Wednesday morning is currently forecasted to be the coldest morning with upper 30s expected for the northern most counties. Marine Issued at 301am EDT Fri Mar 13 2026 Marine conditions remain poor as winds and seas remain elevated. Winds will slowly begin to decrease throughout the day, followed by seas. Conditions once again deteriorate by the end of the weekend into early next week as a stronger cold front moves through. Likely reaching advisory levels following the cold front. Fire Weather Issued at 301am EDT Fri Mar 13 2026 Slightly drier air has begun to filter in behind the front. However, f ire weather concerns still remain low as RH values remain above critical levels. A second cold front moves through early next week and looks to usher in even cooler and drier air in its wake. Current forecast indicated RH values should be just above critical levels during this time. NOAA Tampa FL Office: Watches - Warnings - Advisories FL...None. Gulf waters...Small Craft Advisory until 8am EDT this morning for Coastal waters from Tarpon Springs to Suwannee River FL out 20 NM- Waters from Tarpon Springs to Suwannee River FL out 20 to 60 NM. |
