682 FXUS62 KMFL 301132 AFDMFL Area Forecast Discussion National Weather Service Miami FL 732 AM EDT Sun Aug 30 2026 ...New AVIATION... .KEY MESSAGES... Updated at 727 AM EDT Sun Aug 30 2026 - An active weather pattern will continue through the rest of the work week with high chances of showers and thunderstorms. - The stronger thunderstorms could contain strong gusty winds as well as downpours with high rainfall rates that could lead to localized flooding in urban and poor drainage areas. - High temperatures will continue to peak in the low to mid 90s each afternoon through the next several days. && .SHORT TERM... (Today through Monday) Issued at 403 AM EDT Sun Aug 30 2026 Model guidance remains consistent in depicting a rather wet pattern prevailing across SoFlo through the next several days. U/L high pressure is expected to remain over the SE CONUS, slowly migrating eastward. Meanwhile, the W Atl sfc ridge will remain just north of the state, allowing for a deep easterly wind regime to remain in place. This will keep supporting tropical moisture across the area, with afternoon sea breezes acting as focal points for deeper convection. 00Z MFL and model sounding data shows PWATs remaining in the 1.9- 2.3" range, while short-range model instability variables show CAPE/MUCAPE in the 2-3K J/kg range. At the same time, synoptic analyses depicts a Tropical Upper tropospheric Trough (TUTT) feature gradually lifting north from the Florida Keys through the rest of the peninsula today. Therefore, the combination of these key parameters plus the aforementioned moisture advection (along with dew points in the upper 70s to around 80F) will result in max POPs of 70-80% each day. Potential for strong to severe storms is also anticipated, with wide-spread sea-breeze convection shifting inland through the evening hours. Main hazards will be frequent lightning, damaging wind gusts, and heavy rain. Localized flooding will become a key concern, especially over urban areas prone to flooding. The NWS Weather Prediction Center (WPC) has placed the entire Florida peninsula under a Marginal Risk (at least 5% chance) of Excessive rainfall through Monday. High temperatures today will hit the low-mid 90s across most areas. Peak heat index values will be highly dependent on rain and thunderstorm activity, along with cloud cover. Areas experiencing less cloud cover could have heat index values in the 105F and 110F range. && .LONG TERM... (Monday night through Saturday) Issued at 403 AM EDT Sun Aug 30 2026 Models push a TUTT feature over the state further eastward, while a sfc frontal boundary moves across the SE CONUS. Meanwhile, the W Atl ridge axis will linger just north of the state through the rest of the week, keeping a generally E/SE flow in place across SoFlo. Moisture advection will persist during the long term and keeping tropical moisture in place, with model PWATs remaining above seasonal normals around or above 2" through the work week. This will continue to support scattered to numerous showers and storms each afternoon, with convection initiating along the East coast sea breeze boundary, then pushing inland during the late afternoon hours. Hazards will include gusty winds, heavy rainfall and frequent lightning. Through mid week, models show the aforementioned trough and front progressing eastward, with the two flanking ridges over the CONUS and western Atlantic starting to merge, extending across the entire region. Afternoon showers and thunderstorms will remain likely each afternoon, with coverage maximized across the interior and southwest FL thanks to the continuing easterly flow. The wet pattern should extend through the end of the work week with abundant moisture remaining in place. Temperatures through the period will remain seasonably hot, with highs in the low to mid 90s each afternoon and overnight lows in the low 80s across the coastlines, and mid 70s over the interior. && .AVIATION... (12Z TAFS) Issued at 727 AM EDT Sun Aug 30 2026 VFR conditions should prevail through the majority of the period. Have included VCTS this morning for all eastern terminals for any showers and storms that move onshore from the Atlantic through the afternoon. An easterly to southeasterly breeze will be common through the region, except for KAPF, where a gulf breeze will shift winds west. Scattered storms this afternoon may bring brief periods of gusty or erratic winds and visibility and ceiling restrictions && .MARINE... Issued at 403 AM EDT Sun Aug 30 2026 A gentle to moderate east southeasterly breeze will continue across most of the local waters through the first half of the week. The exception to this will be across the Gulf waters, where winds may become more southwesterly each afternoon as a Gulf breeze develops. Scattered to numerous showers and thunderstorms will develop over the local waters each day. Gusty and erratic winds will be possible in and around thunderstorms. && .PRELIMINARY POINT TEMPS/POPS...
