552 FXUS64 KJAN 131723 AAC AFDJAN Area Forecast Discussion...UPDATED National Weather Service Jackson MS 1223 PM CDT Mon Oct 13 2025 ...New AVIATION... .KEY MESSAGES... - Dry weather, warm afternoons, and cool mornings prevail through the work week. - Chances for showers and storms return to the forecast area on Saturday. && .MESOSCALE UPDATE... Issued at 936 AM CDT Mon Oct 13 2025 Rest of Today...High pressure at the surface remains wedged into the forecast area from the northeast, while ridging aloft continues to increase its presence across the region today. This will result in continued warm temperatures this afternoon, with less humid conditions as dew points mix into the 50s. Under sunny skies, highs this afternoon will top out in the mid to upper 80s with north winds between 5-8 mph. The ongoing forecast is in good shape. Other than some minor adjustments to hourly elements of the forecast based on current trends, no major changes will be made on this morning`s forecast update. /19/ && .DISCUSSION... Issued at 1252 AM CDT Mon Oct 13 2025 High pressure will remain in control this week as an omega block pattern takes shape across the CONUS. As such, dry conditions will promote greater diurnal ranges, with above normal high temperatures persisting through the week, and cooler than normal lows. Fire risk is non zero, though marginal, with RH generally in the 28-35 range. Winds are light, but will continue to monitor conditions and will post a graphic if necessary. Later in the week, as southern trajectories become established, moisture will begin to increase ahead of a low pressure system and attendant surface cold front. At this time, guidance is in good agreement that the ridge holds strong for the lead wave, deflecting to the north. It is the second wave that looks to be a weather maker for us, reflected by an increase in rain/storm chances (30-50%). There is, however, some uncertainty in the evolution exists at this time. In the wake of this system, dry weather returns with weak ridging taking hold again. A wavier pattern appears evident going forward and should supply intermittent rain chances. /SAS/ && .AVIATION... (18Z TAFS) Issued at 1222 PM CDT Mon Oct 13 2025 VFR flight categories will persist at area TAF sites over the next 24 hours. Winds will be from the north around 5 knots this afternoon. These will subside this evening to calm to light from the north around 3 knots. /19/ && .PRELIMINARY POINT TEMPS/POPS...
