858 FXUS62 KTBW 172323 AFDTBW Area Forecast Discussion National Weather Service Tampa Bay Ruskin FL 723 PM EDT Thu Jul 17 2025 ...New UPDATE, AVIATION... .UPDATE... Issued at 722 PM EDT Thu Jul 17 2025 A few thunderstorms continue across the region this evening as boundary collisions continue to take place. Overall, though, the combination of waning daytime heating, ample cloud cover, and drier air advecting into the region are limiting the coverage of storms. Things should continue to wind down over the next couple hours, with quieter weather returning through tomorrow afternoon. The forecast remains on track. .AVIATION... (00Z TAFS) Issued at 722 PM EDT Thu Jul 17 2025 As boundaries continue to linger in the vicinity of TPA, PIE, and LAL, thunderstorms will continue to remain possible for another couple hours. Elsewhere, the potential for thunderstorms is decreasing across the area. There will be another window late tomorrow afternoon for thunderstorms, but the overall probabilities are lower than the past few days. Similarly low probabilities for thunderstorms will linger through the weekend as a drier and more stable air remains across the region. && .DISCUSSION... High pressure is building back in over the area this afternoon, with a southeast low-level flow continuing today. Showers and storms have already begun to pop up and will continue to increase in coverage through the rest of the afternoon and evening, especially closer to the coast. For Friday and through the weekend, ridging aloft will build directly over the state, with increased subsidence and relatively drier air keeping rain chances below normal each day. This will allow high temperatures to climb and heat indices to approach criteria as well. The ridge will then shift westward early next week, with moisture returning to the region along with rain chances going back up. Flow looks to be more onshore for these days, which would keep the highest rain chances inland. && .MARINE... Southeast to south winds will continue over the waters through the next few days, turning onshore with the sea breeze in the afternoon. Conditions are expected to remain below headlines, but daily showers and storms are expected, with locally higher winds and seas. && .FIRE WEATHER... No fire weather concerns as relative humidity values will remain above critical levels. Warm and humid summertime conditions will continue, with scattered showers and thunderstorms each day. && .PRELIMINARY POINT TEMPS/POPS...
