Area forecast discussion, Jul 15, 2:53 PM EDT, 28 minutes before
Area Forecast Discussion National Weather Service Tampa Bay Ruskin FL 253 PM EDT Wed Jul 15 2020 .DISCUSSION... Much heralded return to more typical summer rainy season pattern over the state with increased showers and thunderstorms underway this afternoon as high pressure gradually shifts north across the peninsula with easterly flow setting up for the duration of the forecast period. Troughing aloft is finally exiting the eastern CONUS allowing high pressure to build across the central and eastern CONUS, favoring development of deep easterly flow over the state as surface ridging lifts north of the region. Pattern shift is evident this afternoon as convective activity has blossomed across the interior and Nature Coast. Outflow emanating from the interior convection will propagate westward and interact with the west coast sea breeze triggering additional shower/storm development at locations further west throughout the afternoon and into the evening before pushing offshore/dissipating later this evening and overnight. Expect a similar evolution to play out tomorrow although a bit drier air (PW values below 1.5 inches) working its way westward across the state will likely limit overall convective coverage. Deeper moisture (PW around 2 inches) returns Friday and remains in place through the remainder of the forecast period which, coupled with deeper east to southeast flow, will favor scattered to numerous showers and thunderstorms developing each afternoon in association with sea breeze and convective outflow collisions. Temperatures will hover in the upper 80s to around 90 degrees across coastal locations while reaching into the low/mid 90s just inland, although no advisory criteria is expected to be met. Winds remain out of the east throughout the forecast period with the primary threat remaining thunderstorm activity capable of gusty winds and localized flooding of low-lying and susceptible areas with rainfall associated with the heaviest showers and thunderstorms. && .AVIATION... Mainly VFR expected through period although MVFR/local IFR briefly possible with with afternoon TSRA/SHRA affecting terminals. Winds remain mostly around 10 knots or less across terminals, decreasing to light/variable after 01Z, increasing out of the east after 15Z, again shifting out of the west/northwest during the afternoon. && .MARINE... Surface ridge axis continues drifting north across the waters today with light winds this afternoon, onshore near the coast with isolated to scattered showers and thunderstorms possible. Ridge axis shifts north of the area Thursday with easterly flow setting up and scattered to numerous showers and thunderstorms most likely during the late afternoon and evening hours. Showers and thunderstorms will be capable of producing frequent lightning, locally gusty winds, and rough seas. && .FIRE WEATHER... Sufficient low level moisture expected in place through the forecast period which will keep minimum relative humidity values above critical levels into next week with no Red Flag conditions expected. && .Preliminary Point Temps/PoPs...
