754 FXUS62 KTBW 171856 AFDTBW Area Forecast Discussion National Weather Service Tampa Bay Ruskin FL 256 PM EDT Tue Jun 17 2025 ...New SHORT TERM, LONG TERM, MARINE, FIRE WEATHER... .SHORT TERM (TDY-WED)... Issued at 219 PM EDT Tue Jun 17 2025 Plenty of building Cu`s across across the Sunshine State. ACARs sounding showing just above an inch, which explains why we haven`t seen any shower activity as of yet. High pressure remains in control keeping southeasterly flow in place. Hi- Res models continue to bring pockets of higher moisture late this afternoon and evening. If there is enough instability available when this occurs we should see at least some convection develop, especially across SW portions of the peninsula. Afternoon highs are expected to be near to just above normal in the low to mid 90s with heat indices in the triple digits. On Wednesday, similar conditions are anticipated with PWs increasing later in the day as dry air caps storm coverage. && .LONG TERM (THU-MON)... Issued at 219 PM EDT Tue Jun 17 2025 During the long term, moisture gradually increases as approaching upper level disturbance attempts to push persistent ridge east. Slightly higher rain chances should be supported with increase in moisture, ample instability and the sea breeze. A more easterly flow sets up continuing to support showers across the area and with more coverage. && .AVIATION... (18Z TAFS) Issued at 101 PM EDT Tue Jun 17 2025 Prevailing VFR conditions are anticipated through most of the period. Confidence has increased slightly in storms potentially reaching TPA/PIE/SRQ this evening and PROB30 line has been added to reflect this. Southeasterly winds remain in place with before shifting onshore behind the sea breeze. Lower ceiling and visibilities will be possible if storms develop, otherwise VFR conditions are expected the rest of the period. Temperatures in the low to mid 90s remain in place and very humid...typical uncomfortable conditions during this time. && .MARINE... Issued at 219 PM EDT Tue Jun 17 2025 High pressure continue to dominate across the area. Winds will continue out of the southeast through the period mainly between 5 to 10 knots. The only exception to this will be this afternoon in the offshore waters where winds could get to 10 to 15 knots. Southeasterly flow will bring the best chance for thunderstorms in the evening and overnight hours as storms get pushed off the coast. && .FIRE WEATHER... Issued at 219 PM EDT Tue Jun 17 2025 Drier air remains in place across the region keeping lower rain chances across fire districts today and Wednesday. Moisture gradually increases towards the end of the week, which should support more storm coverage. Southeasterly winds prevail and under this flow showers and storms develop later in the afternoon and evening. Humidity remains above critical values. && .PRELIMINARY POINT TEMPS/POPS...
