834 FXUS62 KTAE 200516 AFDTAE Area Forecast Discussion National Weather Service Tallahassee FL 116 AM EDT Sun Apr 20 2025 ...New AVIATION... .UPDATE... Issued at 825 PM EDT Sat Apr 19 2025 No significant changes to the previous forecast appear necessary. && .NEAR TERM... (Through Sunday) Issued at 345 PM EDT Sat Apr 19 2025 A strong 500 mb high is centered directly over the forecast area this afternoon, with 500 mb heights near an impressively high 5920 meters. The mid-level high will slowly move east over the next 24 hours, emerging off the coast of JAX late Sunday. This feature will keep a strong mid-level cap or lid on the atmosphere, readily preventing any convection. It will also keep temperatures well above normal. Southeast to southerly breezes will continue to reinforce a slightly muggy air mass, with dewpoints running in the upper 50s to mid 60s. && .SHORT TERM and LONG TERM... (Sunday night through next Saturday) Issued at 345 PM EDT Sat Apr 19 2025 The strong 500 mb high center east of JAX on Sunday night will gradually weaken and retreat southeastward toward the Bahamas through Wednesday. This will open the door for weak southwest flow aloft to develop, and a weakening surface cold front will enter northwest Alabama on Monday night and get into central Alabama on Tuesday, before dissipating around Tuesday night. Proximity of this feature will support 15-25 percent rain chances over southeast Alabama on Tuesday PM. Overall, recent guidance runs have been trending downward and drier with rain chances Tuesday, and we have now eliminated rain chances on Monday. Starting Wed night, a 500 mb ridge axis will start to rebuild from the Southwest Gulf to the coastal Carolinas. Flow aloft will weaken, and 500 mb heights will rise modestly. Surface high pressure will strengthen between New England and Bermuda on Thursday, bringing a renewed surge of easterlies or southeasterlies around Thursday night. All things considered, this will support a continuation or a reinvigoration of above normal temperatures, while keeping the atmosphere capped and rain-free. && .AVIATION... (06Z TAFS) Issued at 116 AM EDT Sun Apr 20 2025 VFR conditions are generally expected to prevail through the TAF period with a BKN to OVC cloud deck above 20k ft. Light southeasterly winds this morning increase and turn more southerly as the day progresses. There are some signals for fog near KECP and KDHN near the very end of the TAF period, but kept lower visibility out of this TAF package. && .MARINE... Issued at 345 PM EDT Sat Apr 19 2025 A strong high pressure ridge stretching from Bermuda to the coastal Carolinas will keep moderate to perhaps fresh southeast breezes over the waters through Tuesday morning. The high pressure ridge axis will push south closer to the waters on Tuesday and Wednesday, as a weakening cold front dissipates over the Southeast States. High pressure will strengthen off the Northeast U.S. coast around Thursday, bringing a restrengthening of east or southeast breezes over the northeast Gulf waters. && .FIRE WEATHER... Issued at 345 PM EDT Sat Apr 19 2025 Much above normal temperatures will continue for the next 7 days. No wetting rain is expected either, so that we will be nearing 3 weeks with no rain by the time we reach the last weekend of April. Strong upper level high pressure will remain parked near region through Monday night, then it will start to weaken and retreat southward on Tuesday. Otherwise, gentle or moderate southeast to south breezes will prevail through Monday, before weakening a little on Tuesday. && .HYDROLOGY... Issued at 345 PM EDT Sat Apr 19 2025 No flooding is expected through the at least the last weekend of April. && .SPOTTER INFORMATION STATEMENT... Spotter activation is not requested. However, spotters are always encouraged to safely report significant weather conditions when they occur by calling the office or tweeting us @NWSTallahassee. && .PRELIMINARY POINT TEMPS/POPS...
