| Area Forecast Discussion National Weather Service Melbourne FL 651am EDT Sat May 2 2026 Issued at 419am EDT Sat May 2 2026 Today...A cold front extending from the northern Gulf across north FL this morning is forecast to push into Lake/Volusia counties later this afternoon and across the remainder of EC FL tonight. Ahead of this front, strong and gusty SW winds will produce a windy day. Despite considerable high cloud cover across northern sections, it will not take much heating to mix down 30 knot winds located just above the sfc. So a Wind Advisory has been issued for Brevard/Osceola northward for frequent gusts near 35 mph peaking during the early to mid afternoon. Max temps across Lake/Volusia counties may hold in the upper 80s due to the cloud cover and incoming convection later this afternoon assocd with the front. Southern sections (south of Orlando) will have additional concerns. While also breezy/gusty, better heating will produce hotter temps reaching the mid 90s even at the coast due to lack of any sea breeze due to the offshore (SW) flow. This will produce near record highs at MLB/VRB/FPR. In addition, deep mixing will produce lowest RH values across the south. Low RH combined with the gusty SW winds and already dry conditions has prompted a Red Flag Warning from Osceola/south Brevard to Okeechobee and Treasure coast. Important to note that today will be a very fire sensitive day across all of EC FL but Red Flag criteria are most likely to be met across the south. Any new or existing fires will be capable of spreading rapidly. Increased moisture (PWAT (Precipitable Water) 1.70-2.00") along the frontal zone will combine with cool mid levels (-10 to -11C at 500mb), sufficient instability (MUCAPE ~1000 J/kg) and most notably strong upper level shear 50-65 knots to produce a risk of strong to severe storms this afternoon and eve focused along and north of I 4 but extends across Orlando metro and Brevard/Osceola counties. There are some mitigating factors though, including a warm layer near 700 mb as well as deep mixing which will produce high LCLs. So the tornado threat looks quite low. The primary threat will be strong to damaging wind gusts (5-15% chance). Large hail would be more likely in discrete individual supercells but the shear may be too strong too allow for this. Convection is forecast to weaken by late this eve as the front pushes southward into Okeechobee/ Treasure coast. Any lightning strikes may spark brush fires that smolder for a day or two before flaring up. Sunday...The front will be across south FL but a ripple of energy riding along the front will keep clouds and rain chances across southern sections, with highest rain chances (70%) focused on Martin county. Drier air filtering in from the north will producing increasing sunshine across the north. North to northeast wind flow will produce breezy conditions along the coast at 20-25 mph and noticeably cooler temps in the mid to upper 70s, lower 80s Lake county. Mon-Fri...Zonal flow aloft will continue the first half of the week with a ridge nosing in from the SW Gulf mid week. This ridge will get flattened by a long wave trough rotating across the eastern CONUS late week. At the surface, elongated high pressure will extend from the Gulf Coast States across the Southeast U.S, shifting southward mid-week ahead of the next front pushing into the deep South. The front is forecast to push across the area around Friday but moisture looks rather meager so rain chances are currently low. There will be a quick warm-up with afternoon highs reaching into the low to mid 90s by Wed/Thu. Marine Issued at 419am EDT Sat May 2 2026 Southwest winds will increase today ahead of a frontal boundary draped across north FL. Winds 15-20 knots will be prevalent over the offshore waters especially south of Sebastian Inlet. A period of 20 knots winds (advisory criteria) is forecast this afternoon but will handle with a Caution as duration looks brief. The front will push into the northern waters late today with a wind shift out of the W/NW over the Volusia waters and an increase of 15-20 knots. The front is forecast to continue southward reaching south FL by early Sat. Winds will turn N behind the front at 15-20 knots tonight and N/NE Sunday. Seas build 4-5 FT nearshore and 6 FT in the Gulf Stream behind the front. Do not anticipate need for an SCA (Small Craft Advisory) so will handle with a Caution. Nonetheless, boating conditions will be poor on Sunday. Scattered to numerous showers and embedded storms will accompany the front and linger across the southern waters Sunday. Elongated high pressure to the north builds over the area Mon-Tue with winds gradually becoming more East by Tuesday and speeds 10-15 knots. Winds become SE Wednesday as the trailing ridge axis settles southward toward the area. Seas fall below 6 FT in the Gulf Stream late Monday with 3-4 FT Tuesday and 3 FT Wednesday areawide. Fire Weather Issued at 419am EDT Sat May 2 2026 Strong and gusty southwest to west winds today will increase 15-25 mph with gusts 30-35 mph by early afternoon and produce a fire weather sensitive day across all of east central FL. Hottest temps and lowest RH values will occur south of Orlando where mid 90s and critical RH values are forecast. Thus, a Red Flag Warning has been issued for Osceola, Okeechobee, Martin, Saint Lucie, Indian River and south Brevard counties this afternoon. Dispersion values will be Excellent all areas. Such conditions will support rapid spread of any new or existing fires. An cold front will push into Lake and Volusia counties late today and reach south Florida early Sunday. Scattered showers and lightning storms will accompany the front beginning late this afternoon across the north, spreading southward tonight. Cooler on Sunday behind the front with lingering showers and storms across southern sections. Any lightning strikes will be a concern for new fire starts. Unfortunately, the rainfall this weekend is forecast to bring only limited drought relief.
