533 FXUS62 KTBW 281259 AFDTBW Area Forecast Discussion National Weather Service Tampa Bay Ruskin FL 859 AM EDT Sun Apr 28 2024 ...New UPDATE, AVIATION... .UPDATE... Comfortably warm, dry and occasionally breezy springtime conditions to end the weekend with ridging aloft to the surface. Ridging features to weaken late today, tonight and into Monday with lighter winds and the seabreeze returning Monday afternoon. Latest grids and forecasts on track. Only wx concern is for mariners as the gusty easterly winds continue to produce choppy elevated seas away from the immediate coast. && .AVIATION... (12Z TAFS) VFR conditions continue with another day of diurnal SCT lcl BKN050-060 cumulus clouds and cirrus aloft with gusty easterly winds through the evening surge. Winds decrease overnight and clouds fade as the gradient is expected to weaken Monday with the afternoon seabreeze returning near the coast. && .DISCUSSION... Issued at 430 AM EDT Sun Apr 28 2024 Ridging aloft and at the surface remain over the state this morning leading to another primarily dry and occasionally breezy day across the area. Given the brisk easterly low-level flow, a stray shower cannot completely be ruled out this afternoon as Atlantic moisture moves across the peninsula, however, PoPs remain below 10 percent with no measurable precip expected. Afternoon highs likely to remain within a few degrees of climatology, in the mid to upper 80s. Ridging gradually weakens and shifts east on Mon-Tue as a shortwave pushes across the E U.S., allowing the gradient over the area to relax while the E-SE flow diminishes a bit, enabling sea breeze development during the afternoons. A slight uptick in shower chances is likely on Tue-Wed afternoons as moisture briefly increases over the area, before high pressure again builds over the E U.S./Seaboard over the latter half of the week. Temps increase a few degrees with lows in the mid to upper 60s, while highs range from the mid 80s coastal due to the sea breeze, to the upper 80s/lower 90s away from the coast. PoPs remain generally around 10 percent or less, with perhaps a stray shower possible mainly interior and south. && .MARINE... Issued at 430 AM EDT Sun Apr 28 2024 High pressure with a tight pressure gradient remains over the waters today with advisory conditions diminishing to cautionary levels this morning. Winds diminish further this afternoon before another round of cautionary level conditions likely with the easterly surge this evening and overnight, before diminishing below cautionary levels on Monday and remaining there through the remainder of the week. The sea breeze likely returns early-mid week with winds turning onshore during the afternoons along the coast. && .FIRE WEATHER... Issued at 430 AM EDT Sun Apr 28 2024 High pressure remains the primary influence over the area through the week with minimum RH values in the 30s-40s to approaching critical thresholds for a few hours in the afternoons. Gusty easterly winds possible today during the afternoon into evening hours with high dispersions in some areas. Fire weather risk remains somewhat elevated with these conditions, however, fuels expected to remain moist enough to preclude additional concerns. && .PRELIMINARY POINT TEMPS/POPS...
