896 FXUS62 KMFL 190533 AFDMFL Area Forecast Discussion National Weather Service Miami FL 133 AM EDT Sat Jul 19 2025 ...New SHORT TERM, LONG TERM, MARINE... .SHORT TERM... (Today through Sunday) Issued at 132 AM EDT Sat Jul 19 2025 The deep-layered high pressure will be situated over the Florida Peninsula for the weekend, along with a batch of drier air being filtered into the low to mid levels of the local atmosphere. PWATs will be as low as 1.2-1.3" and no higher than 1.6-1.7" which are both below climatological norms. Add in the subsidence provided by the high pressure, and we have a primarily dry forecast on the horizon this weekend. PoPs along the east coast are nearly non- existent at below 10% both today and Sunday, while the Gulf coast and interior are at a max of 10-20% on Saturday and 20-30% on Sunday. Therefore, no noteworthy impacts are expected as it relates to convection this weekend other than the chance for an isolated thunderstorm for the Gulf side to produce some gustier winds, but likely not to severe levels. Since the weather will be largely quiet this weekend, the main focus will stay on the hotter temperatures produced by less significant cloud cover and subsidence under the ridge. High temperatures both days are expected to reach the low to mid 90s for the east coast metro and mid to upper 90s for the Gulf coast and interior sections of South Florida. Heat indices are still expected to reach triple digits across the entire region, but during the day there is an expectation that some of that drier air aloft mixes down to the surface, which in return can lower dew points by a few degrees and thus the heat index. Additionally, winds are expected to be more due east the next couple days, resulting in a slightly cooler breeze off the Atlantic working inland. Therefore, the best potential for heat indices reaching advisory will criteria will be for the Gulf coast region and western interior locations, but the drier air mixing down is believed to be enough to prevent the issuance of a Heat Advisory today. A short-fused advisory could still be possible for today, but that is not expected at this time. For Sunday, it is unlikely at the moment that an advisory would be needed then as well since the center of the deep-layer high pressure will be shifting into the Gulf and we will see a slight shift to a NE flow in the low to mid levels. && .LONG TERM... (Sunday night through Friday) Issued at 132 AM EDT Sat Jul 19 2025 For the early to middle portion of next week, there continue to be indications that a surface low resultant from lee-side cyclogenesis near the Mid-Atlantic will advect SW across the north and central parts of Florida as well as a broad area of low pressure advecting westward towards the Peninsula from the western Atlantic just northeast of the Bahamas. Overall, details on the evolution of these features are still uncertain, but they will likely cause a disruption in the general easterly flow pattern and result in more widespread convection. However, at this current time the expectation is that while rain chances increase area-wide next week as the drier air filters out of the area and these disturbances start to have an impact on the local weather, the general pattern will still fit a more typical summertime pattern under a low level easterly flow. This means that the Gulf coast and interior are expected to see higher rain chances in the likely to numerous category while the east coast and metro areas see lower rain chances in the chance to likely categories. Temperatures will still remain hot, but likely trending a few degrees cooler in the early to middle portion of next week as rain chances begin to increase again. The end of the week next week has the potential to be drier again as the disturbance is likely to shift into the Gulf and brief ridging rebuilding once again, but the region could still be on the periphery of the low pressure area, thus rain chances don`t differ much from the mid-week period currently. && .AVIATION... (06Z TAFS) Issued at 110 AM EDT Sat Jul 19 2025 VFR expected through the period with mainly dry conditions. E winds at 5-10 kts overnight increase to about 10-12 kts after 14-15Z today. Only chance for isolated SHRA and a rogue TS will be near KAPF late in the day after 20Z, which likely forms as a result of the Gulf breeze moving inland. && .MARINE... Issued at 132 AM EDT Sat Jul 19 2025 Fairly benign conditions continue the next several days across the local waters. A gentle easterly flow is expected across the Atlantic waters as strong high pressure situates itself directly over the area. A more light and variable flow is expected for the Gulf waters. Seas are expected to be 2 feet or less for all local waters. Drier conditions are expected for the next several days as well under the high pressure, but a few isolated showers are still possible at times, mainly for the Gulf waters. && .PRELIMINARY POINT TEMPS/POPS...
