Area Forecast Discussion National Weather Service Miami FL 247 PM EDT Wed Apr 26 2023 ...New SHORT TERM, LONG TERM, AVIATION, MARINE, BEACHES... .SHORT TERM... (Rest of today through Thursday) Issued at 239 PM EDT Wed Apr 26 2023 A sunny morning and early afternoon with temperatures in the mid to upper 80s and 90s over the interior. The atmosphere continues to become more unstable with cooling temperatures aloft as well. The special 18z sounding shows 500mb temps have cooled to -13C and effective bulk shear values around 45 knots. Scattered to numerous thunderstorms will develop with a few strong to severe storms possible. Main impacts will be strong to damaging wind gust, hail and heavy rainfall. There is a chance for large hail up to golf ball size across South Florida today. While highly conditional, there is a chance along storm boundary interactions or storms interacting with the sea breeze that funnel clouds or a brief tornado is possible. Therefore, the Storm Prediction Center has issued a Severe Thunderstorm watch for most of South Florida through 9 PM EDT. Heavy rainfall will be possible in the strongest convection with efficient rainfall rates. This may result in localized flooding, particularly over areas that have seen heavy rainfall in recent days. Therefore, the Weather Prediction Center has placed the region under a Marginal risk of excessive rainfall. Convection will diminish later this evening after sunset as activity will eventually push offshore. Skies will begin to clear with light winds. Overnight lows in the mid to upper 60s with low 70s along the east coast. For Thursday, mid-level ridging will build across the region, with southeasterly winds across the region. Convection will be mainly sea- breeze driven with overall lower coverage compared to today. Mid- levels will also be warming with less potential for deep convection, with general thunderstorms over the interior. Afternoon high temperatures tomorrow will be in the mid/upper 80s with 90s over the interior. && .LONG TERM... (Thursday night through next Tuesday) Issued at 239 PM EDT Wed Apr 26 2023 Thursday Night through Tuesday: A short-wave trough and attendant surface cyclone will transverse the southeastern United States, with the low centered over the Mid-Atlantic states. South Florida will continue to be in the warm sector far south of this feature, where abundant moisture is prevalent. This will allow for more afternoon convective chances especially as minor H500 impulses progress through the area aloft. A weak and brief mid-to-upper level ridge looks to develop over the area Thursday into Thursday night, which will force the surface boundary further north while allowing it to weaken and subsequently will lower the possibilities of showers and thunderstorms for Friday and Saturday. That said, a few showers and an isolated storm are still possible both days particularly near the lake region. Heading into the latter half of the weekend, a low looks to strengthen leeward of the Rocky mountains and eventually moves through the Gulf of Mexico with its associated frontal boundary arriving mid-weekend. This would allow for increased southerly flow as well as scattered showers and thunderstorms on Sunday into Sunday night, but the timing of the frontal passage still has some uncertainty with it. Behind the front, drier air should filter in with quieter weather to close out the long term period into early next week. Temperatures will be hot and oppressive through the weekend, with maximum temperatures generally in the upper 80s to around 90 degrees. Winds will gradually veer out of the southwest/west and northwest by early next week, allowing for afternoon high temperatures to drop to the low/mid 80s. && .AVIATION... (18Z TAFS) Issued at 239 PM EDT Wed Apr 26 2023 Scattered to numerous showers and thunderstorms this afternoon with TEMPOs for TSRA with MVFR conditions. Short fuse amendments may be possible this afternoon as convection develops for IFR and variable wind gust. Generally SE wind flow except for KAPF with the Gulf breeze. Convection diminishes later this evening with L/V winds overnight. SE wind flow tomorrow. && .MARINE... Issued at 239 PM EDT Wed Apr 26 2023 Scattered to numerous showers and thunderstorms this afternoon and evening. A few storms may be strong to severe. Scattered thunderstorms will be possible the remainder of the week over the local waters. Outside of convection, fairly benign marine conditions the remainder of the week. && .BEACHES... Issued at 239 PM EDT Wed Apr 26 2023 A moderate risk of rip currents at the Palm Beach beaches this afternoon and evening with a north-northeasterly swell. An elevated risk of rip currents will remain at Palm Beach beaches through the end of the week. && .PRELIMINARY POINT TEMPS/POPS...
