Area Forecast Discussion National Weather Service Tampa Bay Ruskin FL 129 PM EDT Fri Aug 2 2019 ...HEAVY RAINFALL POSSIBLE THROUGH THE WEEKEND... .DISCUSSION... Late start locally to todays expected thunderstorm activity as SE Gulf convective complex is adding additional mid level heat over the FL Peninsula that is combined with subsidence side of surface trough and additional cloud cover producing slightly lower temps all limiting factors. Regional radar remains very active, so large scale environment remains primed for additional storms once inhibition features move or dissipate later this afternoon or tonight. Upper low spinning over the N Central Gulf to lift but leave deep troughiness through the C Gulf region with SW flow over the E Gulf and FL through the weekend. Once the surface inverted trough moves out of the area tonight, high pressure ridge axis to remain S of the area through the weekend. These features to combine in a moist and unstable environment for numerous showers and thunderstorms with activity developing overnight in the E Gulf and moving ashore in the morning hours before heading inland in the afternoons. Main threat with this activity will be heavy rainfall and possible training or slow movement of cells to produce flooding over already saturated ground. Will continue to monitored the situation for flood watch potential daily. Next week, upper trough to remain over the eastern U.S. into the Gulf while W Atlantic surface ridge axis slowly moves northward over the FL Peninsula mid week. These features will combine with diurnal heating and seabreezes to keep high end summertime PoPs over the area with normal to slightly above average temps. && .AVIATION... Continue to expect SCT-NMRS SHRA/TSRA to keep VCTS in terminals this afternoon into evening hours with areas of MVFR CIGS and LCL IFR vsbys. Flight conditions expected to improve to VFR all sites tonight then E Gulf convection to move ashore towards Saturday morning. && .MARINE...High pressure to sink south and become established with SW-W flow over the area this weekend. Overnight and morning thunderstorms to move inland during the afternoons and as always winds and seas higher in or near any showers and thunderstorms. High pressure ridge to slowly move back north to over the waters next week. && .FIRE WEATHER... No fire weather concerns as relative humidity values will remain above critical levels. No significant fog is expected. && .Preliminary Point Temps/PoPs...
