| Area Forecast Discussion National Weather Service Miami FL 758am EDT Monday May 11 2026 .SHORT TERM... (Today through Tuesday) Issued at 102am EDT Monday May 11 2026 Upper level trough will swing through the SE US today while a surface front will also slide across the southeast. Locally, high pressure will remain in control for one more day. Light southerly flow will continue to pump humid air into the region, with PWAT (Precipitable Water) values this afternoon ranging from 1.8-2 inches. While some mid level dry air will remain in place today, convection will eventually get going mid to late afternoon, with the highest chance Probability of Precipitation around the lake region and over interior locations, with some convection drifting towards the metro late in the day. While dynamics are not very impressive today, a few strong to marginally severe wind gusts can't be ruled out later today, especially around the lake region and over towards the Palm Beach county coast. Temperatures will remain above normal, with high temps ranging from the upper 80s to lower 90s across the metro, and low to mid 90s over the interior. When combined with the high humidity, heat indices will be over 100 this afternoon, so heat precautions will need to be made if you have outdoor plans. Temps will remain mild overnight only falling into the 70s. On Tuesday the frontal boundary will slowly start sliding south across the state, reaching roughly the lake region by late in the day. At the same time, the short wave trough axis will be to our west over the Gulf. Forecast soundings show deep moisture throughout the column with PWAT (Precipitable Water) values around 2 inches and 500 mb temps cooling slightly to -8 to -10C. Scattered showers and thunderstorms are expected to start developing by late morning into the early afternoon, with numerous storms across the area by mid to late afternoon, especially over the metro and interior locations. Lowest PoPs will be along the Gulf coast, but even folks over there may see a few thunderstorms. While not currently outlooked for severe wx, wouldn't be surprised if a few storms approach severe wind limits. Urban flooding may be a threat as well, considering expected slow storm motions and high rainfall rates. High temps on Tuesday will range from the upper 80s to lower 90s. Long Term (Tuesday night through Sunday) Issued at 102am EDT Monday May 11 2026 South FL weather will remain unsettled through mid week as the frontal boundary slides south of the area and settles along the Straits, however the mid/upper level trough will remain over the region until late in the week before finally moving off to the east along with a backdoor front sliding across the state. Upper level ridging will start to build back in for the weekend. Highest Probability of Precipitation will be on Wednesday and Thursday and then gradual drying is expected for the end of the work week and at least first part of the weekend. Temperatures during the extended period will remain above normal, with highs generally ranging from the upper 80s to lower 90s across the metro regions, and low to mid 90s over the interior. Low temps each night will be in the 60s/70s. Marine Issued at 102am EDT Monday May 11 2026 Scattered thunderstorms are expected over the area waters each day this week, which may result in locally hazardous winds and seas. Outside of convection, fairly benign conditions expected with light southerly winds today. Seas generally 2 ft or less in the Atlantic and a foot or less in the Gulf.
