| Area Forecast Discussion National Weather Service Miami FL 250am EDT Thu September 12 2024 ...New SHORT TERM, LONG TERM, Marine EACHES... .SHORT TERM... (Today through Friday) Issued at 247am EDT Thu September 12 2024 Today will be the start of a slight drying trend as former Hurricane Francine pushes north through the Mississippi Valley, with mid-level ridging rebuilding over the southeast Gulf of Mexico. In response, a stalled frontal boundary over Central Florida will finally start to push northward. The associated plume of deep abundant moisture that has been parked over South FL this week will start to also lift north, with PWAT (Precipitable Water) values slightly falling to around 2.0-2.3 inches for today and Friday. Low-level flow will be weak and primarily sea-breeze driven, with mid-level flow out of the W-NW. This setup will support scattered to numerous showers and thunderstorms each day, with overall less coverage compared to what we saw for the first half of this week. Convection will develop from late morning into the afternoon along sea-breeze boundaries, before tapering off after sunset. While the plume of highest moisture will be moving north of the area, there will still be some localized flooding concerns from heavy rain, primarily over the East Coast metro, as well as any areas that have been hit hard in recent days. Heat will be a concern today and Friday, with high temperatures in the low to mid 90s, and peak heat indices ranging from 107-112 degrees each day across South Florida. A Heat Advisory is in effect for the entire area from 10AM to 6PM today, with another round of advisories expected on Friday. Showers and storms will be the only relief from the heat, as very light winds will only exacerbate how hot and humid the conditions feel. Long Term (Friday night through Wednesday) Issued at 247am EDT Thu September 12 2024 Over the weekend, mid-level troughing associated with the remnants of Francine will gradually spread across the Southeast US, flattening the ridge over the southeast Gulf of Mexico. As the troughing slides down over the Florida Peninsula, the W-NW mid-level flow will bring a drier than normal airmass over South FL. PWAT (Precipitable Water) values will drop from 2.0-2.2 inches on Saturday, to 1.8-2.0 inches on Sunday. This will bring rain chances down, with isolated to scattered showers and thunderstorms (30-50% PoPs) each afternoon, developing along sea breeze boundaries and favoring the interior and East Coast metro areas. Conditions will not change much through the early to middle portions of next week as the mid-level troughing gets blocked in place over the Southeast US. Hot and humid conditions will still be in place to start the weekend, with potential heat advisories needed from heat indices in the 105-110 degrees range. From Sunday into the early portions of next week, the mid-level troughing will bring in a slightly cooler airmass, with high temperatures in the upper 80s to low 90s, and peak heat indices around 100-105. Marine Issued at 247am EDT Thu September 12 2024 Light south to southeasterly winds will prevail across the local waters through the end of the week. Seas across the Atlantic waters will remain at 3 feet or less. Across the Gulf waters, seas will range from 2-4 feet today due to increased swell from the distant Francine, but will subside to 3 feet or less on Friday. Scattered to numerous showers and thunderstorms will be possible each day. Winds and seas could be locally higher in and around showers and storms. Beaches Issued at 247am EDT Thu September 12 2024 Light onshore flow and lingering northerly swell will result in a moderate risk of rip currents along Palm Beach County beaches through the end of the week, with a low risk for the rest of the Atlantic Coast beaches. Swell associated with distant Hurricane Francine will lead to elevated rip current risks for the Gulf beaches today. NOAA Miami FL Office: Watches - Warnings - Advisories FL...
