FXUS62 KMFL 061704 AFDMFL Area Forecast Discussion National Weather Service Miami FL 104 PM EDT Wed May 6 2026 ...New KEY MESSAGES UPDATE, AVIATION... .KEY MESSAGES... Updated at 101 PM EDT Wed May 6 2026 - Above average temperatures return today and will continue through the weekend. Probabilities of heat- related impacts across urban areas during this time frame continue to increase. - There is a moderate risk of rip currents for all beaches of Palm Beach county. - Next chance for rain arrives this weekend as a frontal boundary approaches the region. && .SHORT TERM... (Today through Thursday) Issued at 1229 AM EDT Wed May 6 2026 With a lack of significant synoptic forcing, benign and mostly sunny conditions should prevail through the short term period. Sea breezes should dominate the local surface wind flow with east-southeast winds prevailing across the east coast each afternoon and west- southwest winds across Southwest Florida. Upper level ridging slides eastward across the Gulf which should provide enough subsidence to prevent significant convective development and kick off the beginning of another warming trend. Highs today and Thursday should reach the upper 80s along the coasts to the low (maybe even mid) 90s for interior locations with heat index values topping out in the mid 90s. && .LONG TERM... (Thursday night through Tuesday) Issued at 1229 AM EDT Wed May 6 2026 The aforementioned 500mb ridge persists across South Florida to open the long term period and the most noticeable impact will be felt on afternoon high temperatures. Highs across the region are forecast to reach the low to mid 90s with the exception of ocean cooled coastal areas which will max out in the mid to upper 80s. While the mixing down of drier air to the surface will keep apparent temperature and ambient temperature differences lower in separation compared to our standard summer heat, apparent temperatures values in the upper 90s to low 100s are still possible. NWS Prototype Probabilistic HeatRisk depicts a 50-70% probability of Major HeatRisk (Level 3 of 4) on Friday across the east coast metro and increasing to 70-80% on Saturday, Sunday and Monday with some pockets of extreme HeatRisk along the east coast cannot be ruled out. While these probabilistic values may fluctuate as we remain several days out in time, major to extreme HeatRisk can be impactful to anyone without adequate cooling/hydration. Be sure to keep up with the latest forecast updates over the next several days. Aside from the heat, an upper level trough will propagate eastward across the Great Lakes region at the end of the work-week as a developing surface low drags its attendant boundary towards the Florida peninsula. This feature will likely remain just north of our forecast area but could still lead to a slight increase in POPs for Saturday and Sunday as a plume of moisture makes its way northward across the area. At this time, POPs remain around 20-30% Saturday and Sunday and a slight increase to 40-50% on Monday on Tuesday as the boundary sags South. Holding steady for now as it's a bit too early to nail down too many details, as it will all be dependent on the exact progression of the front. && .AVIATION... (18Z TAFS) Issued at 102 PM EDT Wed May 6 2026 VFR expected to continue during the next 24 hours at all terminals. Light to moderate easterly winds will persist through the rest of today, except for a Gulf breeze at APF this afternoon. Winds will again become light and variable tonight. && .MARINE... Issued at 1229 AM EDT Wed May 6 2026 Generally benign marine conditions today with east-southeast winds prevailing across local Atlantic waters. Across local Gulf waters, winds will be east-southeast during the morning hours, but flip to a more west-southwest during the afternoon hours. Wave heights remain 1-3 feet over the next few days. && .PRELIMINARY POINT TEMPS/POPS...
