| Area Forecast Discussion National Weather Service Miami FL 729am EDT Fri August 14 2026 Synopsis Issued at 246am EDT Fri August 14 2026 Mid/upper ridging across the central and southern CONUS will continue amplifying over the next few days. This is in response to the amplification of the eastern US longwave and the eastward propagation of the Pacific longwave. At the surface, and across the Southeast, the low-level ridges in the Gulf and Atlantic will consolidate as the eastern US longwave shifts a bit further east. The net result will be increasing heigheights and prevailing ESE flow across south Florida. In addition, waves of SAL (Saharan Air Layer) air will also bring anomalously warm low-level temperatures over the region. Through next week, there's enough of a consensus in the global ensembles to say that the eastern CONUS trough will lift north while the Pacific longwave will deepen and remain stalled over the extreme western US for much of the period. This will have the effect of amplifying the western reach of the central CONUS ridge and shifting its axis a bit further west. At the surface, this will likely weaken the ridge and separate it once again into a Gulf ridge and a subtropical Atlantic ridge. It also looks as though the SAL (Saharan Air Layer) will be sticking around with a prolonged period of hot and dry low-level air. .SHORT TERM... (Today through Saturday) Issued at 246am EDT Fri August 14 2026 A narrow band of dry SAL (Saharan Air Layer) air can be seen on satellite imagery this morning stretching from the Straits through the Bahamas. This will advect over south Florida during the day today. The rough timing of the dry air should limit convection this afternoon over the eastern half of south Florida, but there may still be enough moisture present across SWFL to initiate scattered seabreeze storms as the easterly flow converges on the Gulf breeze. In the aforementioned easterly low-level flow regime, a weak tropical wave will pass through south Florida and the Straits tonight into Saturday. The consensus regarding the timing of this feature would bring scattered light showers to the east coast in the early to mid morning hours, and then possibly a little more rain (and thunderstorm activity) to the west coast later in the afternoon. While widespread heavy rainfall is not anticipated, it's not out of the question that a storm or two across SWFL could produce 2-4" on Saturday. Temperatures and apparent temperatures will be the primary hazard to end the week and start the weekend. The building ridge and the combination of waves of SAL (Saharan Air Layer) air will keep the combo of high heigheights and warm low-levels in place. Days where drier air mixes to the surface will feature higher actual temperatures than days where dewpoints will be higher, but either way, advisory level heat should be expected each day. Long Term (Saturday night through Thursday) Issued at 246am EDT Fri August 14 2026 Heat, heat, and more heat. Even though the upper ridge will weaken/advect westward, the SAL (Saharan Air Layer) will take a firmer hold of the region and stick around for much of the period. This will create a period of unseasonable high temperatures, lower than usual thunderstorm coverage, and advisory level heat indices. While the breakdown of the ridge pattern may allow for mid/upper level moisture intrusion, it'll still be battling the SAL. Thus, only a gradual increase in Probability of Precipitation is expected through the week. Marine Issued at 246am EDT Fri August 14 2026 Moderate easterly winds are expected today and Saturday as a tropical wave moves across the local waters. Daily wind increases to around 10-15 knots are expected in the seabreeze zone, as well as a light chop. Rain chances will be highest tonight over the Atlantic and late tomorrow over the Gulf with the passage of the tropical wave. Then dry conditions are expected to end the weekend.
