| Area Forecast Discussion National Weather Service Miami FL 638am EST Thu Nov 27 2025 .SHORT TERM... (Today through Friday) Issued at 1229am EST Thu Nov 27 2025 South FL remains unseasonably warm and mild early this morning as southerly flow continues. Patchy to areas of fog expected early this morning over SW FL, especially near the Collier/Lee line. Will need to monitor closely to see if any products are needed. A cold front currently over central FL associated with a system in the eastern US will push through the area later today as a longwave trough digs into the eastern half of the country. Ahead of the front today, plenty of moisture will be in place with PWAT (Precipitable Water) values roughly 1.3-1.6 inches across the area. The deeper moisture combined with sufficient instability will result in additional showers and thunderstorms through early this evening. Afternoon high temps will be in the low to middle 80s. The front should clear the peninsula early this evening, and behind the front much cooler and drier air will filter into the region. Dewpoints will crash into the 20s west of the lake and across SW FL, and into the 40s across the east coast metro. Low temps tonight will be in the upper 40s around the lake to lower 60s over SE FL. A brisk northerly wind is expected on Friday with afternoon wind gusts of 25- 30 mph. Plenty of sunshine during the day however temps will be well below normal with highs only making it into the upper 60s around the lake to mid 70s over SE FL. Long Term (Friday night through Wednesday) Issued at 1229am EST Thu Nov 27 2025 The cooler weather will be short lived as surface high pressure shifts eastward to the middle Atlantic region on Saturday. This will turn our winds back to an easterly direction which will increase temps and dewpoints across South FL. The frontal boundary which clears the area on Friday will lift back north across FL late in the weekend which will increase the chance of showers again for Sunday. As the front lifts into northern FL early next week drier conditions will return however SE low level flow will result in above normal temps through at least Tuesday. The next frontal boundary will approach South FL the middle of next week however at this point looks like it will have very little precipitation associated with it. Marine Issued at 1229am EST Thu Nov 27 2025 Cold front will cross South FL later today and after it's passage hazardous winds and seas are expected beginning tonight and likely lasting through at least Saturday. Waves build to 2-4 ft by tonight and then increase to 5-8 ft in the Gulf and 6-10 in the Atlantic on Friday. Northerly winds behind the front will result in winds of 20- 25 kts and gusts around 30 kts for all local waters. Beaches Issued at 1229am EST Thu Nov 27 2025 Increasing swell beginning Friday will likely result in a high risk of rip currents for the Atlantic Beaches. The risk will continue through the weekend as a strong easterly flow develops. NOAA Miami FL Office: Watches - Warnings - Advisories FL...High Rip Current Risk from Friday morning through Saturday evening for FLZ168-172-173. AM...Small Craft Advisory from 7pm this evening to 7pm EST Friday for AMZ610. Small Craft Advisory from 1am Friday to 7pm EST Saturday for AMZ630.
