Area Forecast Discussion
National Weather Service Tampa Bay Ruskin FL
242pm EDT Tuesday August 11 2026

Issued at 225pm EDT Tuesday August 11 2026

Little, isolated showers are beginning to Probability of Precipitation up on the radar this afternoon, mainly north of I4. Showers will likely be few and far between today as drier air aloft lingers. Heat will continue to be the main story over the next couple of days. Rain chances remain low through most of the week. Rain chances increase Friday before dropping again over the weekend.

Previous discussion...Currently at the surface, the sub- tropical ridge of high pressure extends from the western Atlantic across the Florida Peninsula and will largely hold in place through early next week. In the mid\upper levels, ridging over Florida will gradually build into the southeastern US by late in the week. This pattern will favor broad subsidence that will result in above normal temperatures and unseasonably limited rain chances each day this week. Although the model consensus has backed off the extreme low Probability of Precipitation that were in the forecast from 24 hours ago, rain coverage is still forecast to generally range from 10-40 percent each day through Thursday, with 7-day Quantitative Precipitation Forecasts of around 0.10 to 1.00 inches.

Otherwise, temperatures will run above normal, with afternoon highs in the mid 90s over the interior and low 90s along the coast. With typical summer humidity and minimal rain to cool things off, heat index values will max out each day from around 103-109. As a result, a heat advisory has been issued for most of west central and southwest Florida for this afternoon, with the exception of coastal portions of the counties north of the Tampa Bay.
