Issued at 638 AM CDT Sat Sep 26 2026 - A dry weather pattern will persist into early next week with high temperatures mainly in the 80s. - Rain shower chances return as early as Wednesday, with high temperatures in the upper 80s to low 90s next week. && .DISCUSSION... (Tonight through next Friday) Issued at 1121 PM CDT Fri Sep 25 2026 The 00Z upper-air analysis showed an upper-level low located off the Mid-Atlantic Coast, an upper-level trough off the West Coast, with an upper-level ridge present in between these two features across the Lower Mississippi Valley. This ridge resulted in dry and pleasant conditions across the Mid-South with late evening temperatures in the 70s. Confidence remains high for dry weather through early next week and lower confidence in timing of rain chances towards the latter half of next week. This upper-level ridge will remain in place through early next week, bringing a continuation of dry weather to the area. Highs this weekend will be mostly in the 80s with a few locations in east Arkansas and northwest Mississippi approaching 90 degrees. Temperatures will fall back into the 50s and 60s at night. Lower dewpoint air will mitigate overnight fog development and result in comfortable afternoons despite the warm temperatures. Latest ensemble and deterministic model runs indicate the upper- level ridge will gradually break down towards the middle of next week as a cutoff upper-level low develops near California and the future remnants of Hurricane Polo consolidate and move towards the Southern Plains and portions of the Lower Mississippi Valley. NBM rain chances have decreased slightly as the ECMWF has been trending a bit slower than the GFS and Canadian solutions. A large spread in GEFS mid-level heights exists with subsequent rain chances needing additional adjustments depending on the eventual track of this low. && .AVIATION... (12Z TAFS) Issued at 638 AM CDT Sat Sep 26 2026 High confidence in VFR conditions across all terminals through the next 30 hours. A strong and persistent upper-level high- pressure system will maintain light northeast winds and dry conditions across the region. AC3 && .FIRE WEATHER... Issued at 1121 PM CDT Fri Sep 25 2026 An upper-level ridge located over the Lower Mississippi Valley will continue to bring dry and warm conditions through the weekend. Afternoon minimum relative humidity (RH) values will hover between 35 to 45 percent on Saturday and as low as 25 to 30 percent on Sunday. However, light 20-foot surface winds under 10 mph, will mitigate any critical fire-spread conditions. Fog potential will be light and localized, primarily restricted to early morning patchy fog along low-lying river basins and lakes. && .MEG WATCHES/WARNINGS/ADVISORIES... AR...None. MO...None.
