982 FXUS62 KKEY 101447 AFDKEY Area Forecast Discussion National Weather Service Key West FL 1047 AM EDT Fri May 10 2024 ...New DISCUSSION, MARINE, AVIATION... .DISCUSSION... Issued at 1047 AM EDT Fri May 10 2024 It has been a very quiet, warm morning across the Florida Keys, with temperatures already nearing the mid 80s and dew points in the mid 70s. Meanwhile across the Panhandle of Florida, severe weather has been assaulting communities, with multiple tornado and severe thunderstorm warnings issued. This severe weather has been taking place ahead of a cold front draped across the Southeast and into the Gulf. Surface analysis shows high pressure in the central North Atlantic still weakly influencing the winds across the Florida Keys, despite being shoved further offshore by the trough associated with the aforementioned frontal boundary. Surface winds are currently from the south, which is generally a very unfavorable direction for moisture advection for the Keys. An already very dry airmass was sampled by this morning`s sounding, and we may actually dry out even more by this afternoon thanks to this southerly flow. Winds will begin to weaken as the pressure field becomes weakly chaotic this afternoon. Due to the very dry airmass in place across the forecast area, showers are out of the question for today. No changes were needed to the current forecast. && .MARINE... Issued at 1047 AM EDT Fri May 10 2024 There are no watches, warnings, or advisories in effect for the Florida Keys coastal waters. From synopsis, moderate southeast to south breezes late this morning will slacken and veer to the southwest this afternoon, as high pressure over the western Atlantic moves further offshore. Winds will continue to veer around the compass during the weekend as a weak frontal boundary moves down the Florida peninsula. The front will dissipate near the Keys waters on Sunday, then gentle to moderate southeast breezes will resume early next week as another high pressure area moves over the western Atlantic. && .AVIATION... (15Z TAFS) Issued at 1047 AM EDT Fri May 10 2024 VFR conditions will prevail at both EYW and MTH island terminals through the TAF period, with nil rain and thunder chances. Near surface winds out of the south 7 to 10 knots will veer to the southwest this afternoon, before becoming light and variable overnight. && .CLIMATE... On this day in 1963, the daily record low temperature of 61F was recorded in Marathon. This is the coldest temperature ever recorded in May in the Marathon area. Temperature records date back to 1951 for May. && .PRELIMINARY POINT TEMPS/POPS... Key West 87 78 88 78 / 0 0 0 0 Marathon 87 78 88 79 / 0 10 0 10 && .KEY WATCHES/WARNINGS/ADVISORIES... FL...None.
