323 FXUS64 KJAN 220534 AAB AFDJAN Area Forecast Discussion...UPDATED National Weather Service Jackson MS 1234 AM CDT Fri Aug 22 2025 ...New AVIATION... .DISCUSSION... Issued at 250 PM CDT Thu Aug 21 2025 Afternoon update: The weather has been less impactful today with relatively reduced heat and convective rainfall coverage, and no significant adjustments are being made to the prior forecast reasoning. We may need to eventually monitor for fire weather concerns, but that would be looking ahead to next week and beyond as discussed below. /EC/ For tonight, temps in the 60s are expected over much of the northern half of the area. Friday will be similar to today, except the front will be slightly farther south, so areas south of I-20 will begin to experience less muggy conditions during the day tomorrow. There will still be sufficient moisture and convergence along the front for scattered diurnal convection across central LA and south/southeast MS. By Saturday morning, lows in the 60s can`t be ruled out at some cooler spots even into south MS. Saturday through Wednesday: A similar pattern will continue into this weekend, though the original front will begin to wash out near the Gulf Coast. Conditions will be seasonably warm in most areas, but more tolerable due to lower humidity. Isolated to scattered diurnal convection will primarily be limited to south/east MS. Mornings will also be more pleasant and slightly cooler. As we go later into next week and the weather remains dry, we may need to monitor for an increase in fire weather concerns, even with the recent rainfall. A reinforcing front will arrive early next week bringing a more substantial push of drier air southward into the area, and this may result in stronger mixing and critically low RH values. Long term indices we used to monitor fire danger suggest it will not take a lot of rainfall deficit to cause problems. By Tuesday, high temps below 90 will become more common, and most areas will have morning lows in the 60s. A few cooler spots in north MS could even touch the upper 50s by Thursday morning. Rain chances will be limited, though isolated showers could return by midweek. /DL/EC/ && .AVIATION... (06Z TAFS) Issued at 1234 AM CDT Fri Aug 22 2025 Patchy fog or low stratus are possible through shortly after sunrise, mainly across south and east MS. Then scattered SHRA and TS are possible mainly across south MS during the afternoon and early evening. Otherwise, VFR conditions will prevail through the TAF period with generally light wind. /DL/ && .PRELIMINARY POINT TEMPS/POPS...
