821 FXUS62 KKEY 301526 AFDKEY Area Forecast Discussion National Weather Service Key West FL 1126 AM EDT Thu May 30 2024 ...New DISCUSSION, MARINE, AVIATION... .DISCUSSION... Issued at 1120 AM EDT Thu May 30 2024 Yet another morning of brief scattered shower and thunderstorm activity over the Florida Bay and portions of the Upper Keys. This activity has slowly decayed over the past hour. Outside of that activity, skies are mostly sunny across the Florida Keys island chain and the adjacent nearshore and offshore coastal waters. With the exception of any rain-cooled spots, temperatures are already reaching the upper 80s at many communities. Coupled with dew points in the mid 70s, heat indices are in the upper 90s at many locations. For this afternoon, light and variable winds coupled with daytime heating will likely promote the formation of a broken cumulus cloud line over portions of the Lower and Middle Keys. In addition, a weak shortwave pushing across Florida will likely enhance diurnally- favored convection over the South Florida Mainland that may then dive outflow boundaries southward towards the Keys this evening. These convective evolutions and trends will be monitored. Given the uncertainty, the relatively dry air sampled in the 12z sounding at KEY, and the largely mesoscale nature of these convective sources, slight rain and thunder chances seem appropriate for now. No changes proposed to the inherited forecast at this time. && .MARINE... Issued at 1120 AM EDT Thu May 30 2024 Light to gentle, occasionally variable breezes are expected this afternoon. High pressure currently over south- central Canada will emerge off the Mid-Atlantic coast by the end of the work week. This will result in fresh northeast to east breezes beginning as early as Friday night, lasting through early next week. A Small Craft Advisory may be required for portions or all of the Florida Keys beginning as early as Friday night, continuing through Sunday. && .AVIATION... (15Z TAFS) Issued at 1120 AM EDT Thu May 30 2024 VFR conditions will prevail at both island terminals through the TAF period. Near surface winds are light and variable but will become 5 to 10 knots and easterly early this evening. && .CLIMATE... On this day in Keys Weather History, a waterspout moved onshore as an F0 tornado along the north end of Duval Street in 1999. No damage was reported from this tornado. && .PRELIMINARY POINT TEMPS/POPS... Key West 92 81 91 81 / 10 20 20 20 Marathon 90 82 89 81 / 20 20 20 20 && .KEY WATCHES/WARNINGS/ADVISORIES... FL...None.
