544 FXUS62 KTBW 280011 AFDTBW Area Forecast Discussion National Weather Service Tampa Bay Ruskin FL 811 PM EDT Sun Jul 27 2025 ...New UPDATE, AVIATION... .FOR THE EVENING UPDATE... Issued at 804 PM EDT Sun Jul 27 2025 Record heat this afternoon with Tampa recording its first ever triple digit reading of 100...and now a few strong/severe thunderstorms are pushing down Tampa Bay and across southern Pinellas. The showers/storms will push offshore and end by midnight, with skies becoming mostly clear overnight. The strong U/L ridge will hold over the forecast area tomorrow with another day of record heat and extremely high apparent temperatures...which will likely end again with scattered strong thunderstorms during the late afternoon and evening hours. && .DISCUSSION... Issued at 300 PM EDT Sun Jul 27 2025 High pressure over the southeast U.S. at the surface and aloft will continue to slowly drift west over the next few days, but remain close enough through Monday to keep the rather hot and dry conditions across the area. Enough moisture, precipitable water 1.6 to 1.7 inches, has returned though to allow for isolated to scattered convection to develop later this afternoon and evening and again during Monday afternoon and evening. By midweek deeper moisture will return allowing for higher rain chances, but then the low level ridge axis will have sunk to across south Florida with a southwesterly flow (Regime 4) setting up. Therefore, the highest rain chances during the second half of the week will shift to the interior. Temperatures will continue to climb to near record values again on Monday and Tuesday with heat indices climbing to around 112. A few isolated locations could see heat indices a little higher like today, but not expected to be widespread enough for an Excessive Heat Warning. For now have issued another Heat Advisory for Monday, and may end up needing another one for Tuesday. && .AVIATION... (00Z TAFS) Issued at 804 PM EDT Sun Jul 27 2025 Scattered evening showers and thunderstorms mainly vcnty SRQ/TPA with LCL MVFR CIGs and IFR VSBYs ending by midnight. Skies will become mostly clear at all terminals after midnight with VFR conditions expected into Monday. && .MARINE... Issued at 300 PM EDT Sun Jul 27 2025 Hot and dry weather continues into the work week as strong high pressure remains in control. There could be some isolated to scattered thunderstorms around the Tampa Bay area late this afternoon, pushing offshore this evening. A similar setup will take place each evening before greater rain chances return later in the work week. Outside of thunderstorms, winds will remain below 15 knots with seas of around 2 feet or less. && .FIRE WEATHER... Issued at 300 PM EDT Sun Jul 27 2025 The hot and rather dry pattern will continue early this week with moisture gradually increasing during midweek. Relative humidities will remain above critical levels with winds generally less than 10 mph, so no fire weather concerns are expected. Winds however could be gusty and erratic in the vicinity of any showers and thunderstorms. && .CLIMATE... Issued at 300 PM EDT Sun Jul 27 2025 Tampa has reached 99 degrees today setting a new daily and monthly record for July.
