381 FXUS64 KJAN 301826 AFDJAN Area Forecast Discussion National Weather Service Jackson MS 126 PM CDT Sat Aug 30 2025 ...New DISCUSSION, AVIATION... .DISCUSSION... Issued at 108 PM CDT Sat Aug 30 2025 A weak low-level vorticity center can be seen in a swirl of low- level clouds over southeast Mississippi this afternoon, but prevailing northerly flow over the region will reinforce drier air over our forecast area through the remainder of the weekend. The flow aloft should amplify quickly as an upperl-evel ridge over the Rockies elongates and deep troughing digs over the eastern half of the CONUS. Upper-level heights in the core of this trough will be about 2-4 standard deviations below normal for this time of year - resulting in suppressed early September temperatures running about 5 degrees below normal. And PWAT values falling below 1.5 inches should bring the Gulf Coast atmosphere to a little drier than average for early September. The broad trough over the eastern half of the country still means disturbances could bring some chance for showers or storms to the region, and Tuesday into Thursday currently looks to be the best time range for that to occur. Timing and strength of the wave details could adjust this window for rainfall. /NF/ && .AVIATION... (18Z TAFS) Issued at 108 PM CDT Sat Aug 30 2025 Ceiling and visibilities are improving as earlier fog has dissipated through the morning, bringing majority of sites to VFR/MVFR flight conditions. Cloud cover will gradually clear out of the area, leaving clear skies with northerly winds near 10 kts. VFR flight conditions are expected through the rest of the period. /SW/ && .PRELIMINARY POINT TEMPS/POPS...
