Area Forecast Discussion...UPDATED National Weather Service Miami FL 818 AM EDT Tue Sep 23 2025 ...New UPDATE, AVIATION... .UPDATE... Issued at 816 AM EDT Tue Sep 23 2025 Plenty of moisture remains over South Florida this morning, with GOES-based Total Precipitable Water (TPW) values over 2 inches. Surprisingly, the last couple of HRRR model runs have decreased the amount and coverage of precipitation across the area today, but with the copious moisture and enough filtered morning sunshine leading to surface instability, showers and thunderstorms should once again develop along the seabreezes in the 11 AM to Noon time frame. Adjusted PoPs slightly to concentrate the highest chances over the interior/Everglades, and slightly lower over the east and west coast metro areas. With light low level wind flow and weak forcing aloft, the movement of showers and thunderstorms will be largely outflow-dominant and slightly favor a NE to SW motion towards the western portion of the peninsula during the early and mid afternoon. Outflows will also be able to spread back to the east and possibly affect east coast metro areas again late in the afternoon. Main threats will be the usual gusty winds with the stronger thunderstorms, occasional to frequent lightning strikes, and locally higher rain amounts which could exceed 3 inches in isolated spots. Favored areas of the highest rain amounts will likely be over the interior, but one or two metro locations could also get these higher values which could lead to localized flooding. && .SHORT TERM... (Today through Wednesday) Issued at 104 AM EDT Tue Sep 23 2025 Unsettled weather will continue today and Wednesday as what's left of a lingering frontal boundary dissipates today. At the surface, weak high pressure is over the northeast Gulf and western Atlantic. Convection today and tomorrow will be sea-breeze driven during the afternoon and early evening hours, with the highest PoPs focused over interior and SW FL, although with the easterly flow fairly weak, portions of the east coast metro will be in play early to mid afternoon before the focus shifts into the interior late afternoon into the early. With the weak steering flows in place, can't count out an isolated urban flood risk across the metro. Overall dry conditions are expected overnight with just a few coastal showers or isolated thunderstorms possible. Temperatures will be about a degree or so above normal with highs today and tomorrow ranging from the upper 80s to lower 90s, and low temps from the middle to upper 70s. && .LONG TERM... (Wednesday night through Monday) Issued at 104 AM EDT Tue Sep 23 2025 Seasonal conditions are expected Thursday and Friday with convection both days generally sea-breeze driven during the afternoon and early evening hours. Things get more interesting this weekend as a trough dives into the Gulf and a frontal boundary approaches the area and likely stalls in the vicinity of Lake Okeechobee. At the same time, a disturbance currently east of the Leeward Island has a medium chance of development over the next 7 days. While the surface front and upper level trough should steer any potential development away from South FL, some peripheral impacts could be possible if there is any development, so this system is worth watching as the week progresses. Regardless, the frontal boundary stalling in the vicinity of Lake Okeechobee will allow the atmosphere locally to remain fairly saturated which is what forecast soundings show, with PWAT values generally 2.1-2.3 inches. Expect the unsettled weather to continue through the remainder of the extended forecast period. Temperatures will remain slightly above normal through the extended period with highs each day in the upper 80s to lower 90s. Low temps will generally range from the lower 70s around the lake, to mid and upper 70s over the rest of South FL. && .AVIATION... (12Z TAFS) Issued at 816 AM EDT Tue Sep 23 2025 VFR conditions through 16z-18z, then scattered SHRA/TSRA developing along Atlantic and Gulf seabreezes and spreading over the interior of the South FL peninsula through 00z. Best chances of lower ceilings/vsby with TSRA and gusty wind at terminals will be from 18z- 22z, with lingering chances likely through 00z-02z. Light land breeze through 16z, then seabreezes 8-12 knots from 16z-00z before returning to land breeze after 00z. && .MARINE... Issued at 104 AM EDT Tue Sep 23 2025 Gentle easterly winds expected over the area waters through mid week, with brief west to southwesterly winds during the afternoon over the near shore Gulf waters. Seas in the Atlantic generally 2-3 ft and a foot or less in the Gulf. Scattered thunderstorms today and Wednesday may result in locally hazardous winds and seas. && .BEACHES... Issued at 104 AM EDT Tue Sep 23 2025 Lingering NE swell will result in an elevated risk of rip currents through mid week for the Palm Beaches. && .PRELIMINARY POINT TEMPS/POPS...
