444 FXUS62 KMFL 240530 AFDMFL Area Forecast Discussion National Weather Service Miami FL 130 AM EDT Mon Aug 24 2026 ...New SHORT TERM, LONG TERM, AVIATION, MARINE... .KEY MESSAGES... Updated at 123 AM EDT Mon Aug 24 2026 - Smoke from wildfires in the area could produce lower visibilities and unhealthy air quality over portions of the Everglades and western suburbs. - Scattered showers and thunderstorms expected to develop in the afternoon and evening again today. An isolated marginally severe storm or two is possible. && .SHORT TERM... (Today through Tuesday) Issued at 123 AM EDT Mon Aug 24 2026 The deep trough draped across most of the eastern US and associated low pressure center over the Great Lakes will start to lift more northeast early this week. Additionally, another Saharan Air Layer (SAL) looks to advect into the area today. The thickness of this SAL is expected to be much less than the previous one, but it is still expected to create a drier local atmosphere that produces less widespread rain today. Light flow across the region will create a setup where most of the rain showers and thunderstorms that do form will be observed over interior areas of South Florida where the sea breezes collide. However, some activity can drift towards the coasts as additional convection develops along outflow boundaries. An isolated severe thunderstorm or two once again cannot be ruled out in the form of downburst winds because the SAL helps to steepen low level lapse rates. Strongest storms are are most likely to occur again with a storm formed by converging boundaries or cell mergers. Primary impacts to monitor for will be periods of heavy rain that could lead to localized flooding, frequent cloud-to-ground lightning, and strong wind gusts. The SAL will start to filter out on Tuesday, allowing for the deep moisture environment (PWATs ~1.7-2.0") to be utilized for widespread convection during the peak heating time of day in the afternoon and evening. High end PoPs rise to 50-70% over the interior on Tuesday which is up from 30-40% today. PoPs near the coasts will also be about 20% higher tomorrow when compared to today. Even with the increased rain chances Tuesday, QPF is still not too impressive at generally 0.5-1.0" across the region. Guidance also indicates potential for a mid-level low to form off the coast of Cuba and advect northwards late Tuesday into Tuesday night that could provide some extra upper level support for convection if the feature forms as modeled. However, uncertainty is high with this as it`s not clearly defined across many of the ensemble members suite. High temperatures early this week will continue to be in the low to mid 90s. Maximum heat index values will primarily be in the 100-105F range, but some areas will experience brief periods where indices could reach into the 105-110F range. && .LONG TERM... (Tuesday night through Sunday) Issued at 123 AM EDT Mon Aug 24 2026 For the middle to end of this week and into next weekend, surface and low level high pressure centered over the western Atlantic will begin to expand back over the region and cause winds to shift back to an easterly or east-southeast direction. This easterly to east- southeast regime will produce a pattern that is common in the summertime across South Florida with convection being driven by the sea breeze circulations and being steered towards the Gulf coast areas. At the same time, the weak SAL will dissipate by mid-week and allow for the deeper moisture to be utilized for widespread shower and thunderstorm development. At the same time, we will be monitoring for some weak disturbances and vorticity maxima forming off the Caribbean islands as much of the guidance is showing potential for these weak lows to form, mainly in the mid-levels and advect close to the region. Nevertheless, abundant moisture (PWATs 1.8-2.0+") will be present for Wed-Fri and into the weekend for any vorticity and diurnal heating instability to take advantage of. Highest rain chances (60-80%) each day will be across interior and Southwest Florida as the easterly to east- southeast wind regime favors these areas receiving the most widespread rain. High temperatures are projected to remain in the low to mid 90s each day. Overnight lows range from the low 70s across the interior and lake regions to the upper 70s and low 80s along the coastal metros. && .AVIATION... (06Z TAFS) Issued at 123 AM EDT Mon Aug 24 2026 Winds remain light and variable across all terminals overnight before increasing out of the SE after 16z to around 10 kts across the east coast terminals. At KAPF, winds will increase out of the SW after 16z Monday as a Gulf breeze pushes inland. Scattered SHRA/TSRA expected to develop mostly inland and away from terminals, but VCTS in place after 16Z with monitoring for short- fused AMDs. && .MARINE... Issued at 123 AM EDT Mon Aug 24 2026 Light to gentle west-southwest winds are expected across the Gulf waters early this week with southeasterly winds across the Atlantic. Seas will remain at 1-2 feet or less each day across all of the local waters. Scattered showers and thunderstorms are possible late each day and in the late night hours over the waters, which may result in locally hazardous winds and seas. && .PRELIMINARY POINT TEMPS/POPS...
