084 FXUS62 KMFL 281855 AFDMFL Area Forecast Discussion National Weather Service Miami FL 255 PM EDT Fri Jun 28 2024 ...New LONG TERM... .SHORT TERM... (Rest of today through Saturday) Issued at 1223 PM EDT Fri Jun 28 2024 Mid level ridging will continue to build over the Florida Peninsula throughout the rest of today and heading into Saturday. At the surface, high pressure in the western Atlantic will push closer to the region during this time frame. This will help to shift the winds from a south southeasterly direction today to a more easterly direction heading into Saturday. With mid level ridging building across the area, the main driver for shower and thunderstorm development will be the sea breezes as they push inland. With a rather light south to southeasterly wind flow today, showers and thunderstorms will be slow moving throughout the day. With the potential for convection to develop over portions of the east coast metro areas this afternoon, localized flooding will be possible due to the slow motion of the showers and thunderstorms. With a lack of mid to upper level support, chances for strong thunderstorm development will remain rather limited this afternoon. High temperatures today will rise into the lower to mid 90s across most areas. Heat index values will be even hotter as they will range between 105 and 110 through the afternoon hours. Heading into Saturday, easterly wind flow may increase a little bit across the region as the surface ridge axis pushes closer to the region. Sea breeze and other mesoscale boundaries will still be the main driver for shower and thunderstorm development, however, with a bit more of an easterly wind flow in place, the highest chances of convection will push over the interior and west coast as the day progresses. Strong thunderstorm development will still remain rather limited due to lack of mid to upper level support. High temperatures will rise into the lower 90s across the east coast metro areas, and into the mid 90s across the interior portions of Southwest Florida. Heat index values will once again rise to 105 or higher especially across the interior sections. && .LONG TERM... (Saturday night through next Thursday) Issued at 254 PM EDT Fri Jun 28 2024 Models remain consistent in expanding a ridge aloft over the region, which will become deeper during the weekend. This will bring veering winds across SoFlo to a more SE flow by Sunday. Meanwhile, expect the current summer pattern to continue into early next week with daytime heating and sea breezes acting as the main drivers of afternoon convection each day. Isolated to scattered showers and thunderstorms should develop over the East Coast Metro areas during the late morning/early afternoon hours, then increasing in coverage and shifting west into interior and Gulf Coast areas during the late afternoon/early evening hours. Localized flooding remains a primary concern due to the weak flow pattern. Temperatures should remain around or slightly warmer than normals, with afternoon highs in the upper 80s to low 90s, and heat indices reaching triple digits. Overnight lows should remain in the mid to upper 70s. && .AVIATION... (18Z TAFS) Issued at 1223 PM EDT Fri Jun 28 2024 Mainly VFR conditions will prevail throughout the forecast period. Winds will increase out of the SE this afternoon across the east coast terminals as the sea breeze pushes inland. Scattered to numerous showers and storms will develop this afternoon near the terminals creating periods of sub-VFR conditions. At KAPF, winds will increase out of the WSW this afternoon as a Gulf breeze develops. Most of the convection will gradually diminsh this evening as winds become light and variable. && .MARINE... Issued at 1223 PM EDT Fri Jun 28 2024 A gentle to moderate south to southeasterly wind flow this afternoon across the local waters will gradually become more easterly heading into the upcoming weekend. Seas across 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 will be possible each day. Winds and waves could be locally higher in and around showers and storms. && .PRELIMINARY POINT TEMPS/POPS...
