035 FXUS64 KJAN 210859 AFDJAN Area Forecast Discussion National Weather Service Jackson MS 359 AM CDT Sat Sep 21 2024 ...New DISCUSSION... .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 thorugh 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...
