701 FXUS64 KJAN 211742 AAC AFDJAN Area Forecast Discussion...UPDATED National Weather Service Jackson MS 1242 PM CDT Sat Sep 21 2024 ...New AVIATION... .DISCUSSION... Issued at 359 AM CDT Sat Sep 21 2024 Today and Tonight: Ridging aloft will remain wedged into the Lower Mississippi River Valley from the southwest, as high pressure at the surface remains over the southeast United States. This will continue to result in quiet weather across the forecast area today into tonight. Humid conditions will exist with dew points only mixing into the upper 60s to around 70. Highs will be above normal as they top out in the mid 90s under mostly sunny skies. Lows tonight will also remain above normal as they range from the upper 60s to lower 70s. /19/ Sunday through Friday: We will be monitoring the tropics, more specifically the northwest Caribbean to Gulf of Mexico region, for potential tropical development during the longer ranges of the forecast. Until a distinct system forms, there will be a considerable amount of uncertainty and ensemble spread in the global models. Confidence is growing however with the synoptic features that could help steer a "potential" system into at least southern portions of the Gulf of Mexico late in the week. Otherwise, the upper level ridge will remain the primary weather influence as we finish up the weekend and begin the new week, and this will keep warm and dry conditions with above normal temperatures over the forecast area. As we go through mid to late week, considerable troughing over the western and central CONUS will impinge on the ridge, and the increased influence from the westerlies will bring greater rain chances and slightly cooler temperatures. /EC/ && .AVIATION... (18Z TAFS) Issued at 1239 PM CDT Sat Sep 21 2024 Few to scattered daytime cumulus field has developed around the forecast area to start the period, with VFR conditions expected to prevail at the TAF sites through the period. Some patchy BR cannot be ruled out near some sites around 12Z Sunday, but confidence in any impacts was too low to mention at this time. /NF/ && .PRELIMINARY POINT TEMPS/POPS...
