617 FXUS62 KMFL 290552 AFDMFL Area Forecast Discussion National Weather Service Miami FL 152 AM EDT Sat Jun 29 2024 ...New SHORT TERM, LONG TERM, AVIATION, MARINE... .SHORT TERM... (Today through Sunday) Issued at 147 AM EDT Sat Jun 29 2024 Today, easterly wind flow is expected to increase slightly across the region as the surface ridge axis approaches. While sea breeze and other mesoscale boundaries will continue to be the main drivers for shower and thunderstorm development, the enhanced easterly wind flow will shift the highest chances of convection towards the interior and west coast as the day progresses. Strong thunderstorm development remains limited due to a lack of mid to upper-level support. Forecast models consistently expand a ridge aloft over the region, which will deepen over the weekend. This will result in veering winds across South Florida, shifting to a more southeasterly flow by Sunday. Consequently, the bulk of convection is expected to develop along the western metro and eastern interior areas, with the possibility of extending further along the east coast, particularly if a westerly augmentation in the steering flow materializes. Localized flooding will be the primary hazard, although the recent days of relatively lower rainfall over the east coast may help mitigate the rainfall amounts required to cause flooding. High temperatures will reach the lower 90s across the east coast metro areas and the mid-90s in the interior portions of Southwest Florida. Heat index values will rise to 105 or higher, especially across the interior sections. Some locations may approach heat advisory criteria, so the issuance of heat advisories cannot be ruled out. && .LONG TERM... (Sunday night through Friday) Issued at 147 AM EDT Sat Jun 29 2024 The synoptic pattern of predominantly easterly flow is expected to continue into early next week, with daytime heating and sea breezes driving afternoon convection daily. The east to southeasterly boundary layer flow will focus most convection over the interior and Gulf Coast regions, though some sporadic convection may also affect the east coast. Isolated to scattered showers and thunderstorms are anticipated to develop over the East Coast Metro areas during the late morning and early afternoon, increasing in coverage and shifting west into the interior and Gulf Coast areas by late afternoon and early evening. Localized flooding remains a primary concern due to the weak flow pattern. Temperatures will remain around or slightly above normal, with afternoon highs in the upper 80s to low 90s and heat indices reaching triple digits. Overnight lows will be in the mid to upper 70s. && .AVIATION... (06Z TAFS) Issued at 147 AM EDT Sat Jun 29 2024 Generally VFR though showers and storms are expected to develop with the focus shifting from east to west through the day. Sub-VFR conditions are possible at terminals directly impacted by convection which could necessitate short-fused AMDs. && .MARINE... Issued at 147 AM EDT Sat Jun 29 2024 Winds will gradually shift out of the east through this weekend. Seas in the Atlantic and Gulf waters will remain at 2 feet or less through the weekend and into early next week. Scattered to numerous showers and thunderstorms are expected each day, with locally higher winds and waves in and around showers and storms. && .PRELIMINARY POINT TEMPS/POPS...
