.DISCUSSION... Issued at 142 PM CDT Thu Sep 11 2025
Tonight and Friday: Warmer than normal temperatures and dry weather will continue through Friday. Our CWA will remain on the eastern periphery of a large 594dam ridge that was part of the omega block centered over the CONUS. Surface analysis had a 1019mb ridge oriented northeast to southwest across our CWA. This ridge will change very little through Friday. The combined ridging surface and aloft will help maintain the warmer than normal temperatures across our region with highs Friday topping out in the low to mid 90s. Our normal highs run in the upper 80s. Lows Friday morning will be in the upper 60s to near 70F. Our normal lows run in the mid 60s. /22/
Friday Night through Thursday...
Weather conditions will remain generally quiet across the southeast CONUS this weekend through early next week as global guidance continues to show the omega block pattern with ridging over the central CONUS. HREF guidance is starting to show low probabilities (around 5-10%) of patchy fog development across portions of southeast MS by early Sunday morning. Confidence is too low to introduce any fog graphics at this time, however shallow fog will be possible around dawn. Dry conditions will continue across our forecast area heading into early next week as sfc ridging from the northeast will continue over our forecast area. This will contribute to a warming trend the extended period with afternoon highs peaking out in the mid to upper 90s. The latest U.S. Drought Monitor continues to show abnormally dry to moderate drought conditions across our northern zones. Expect conditions to worsen through the mid-week given the lack of rainfall in the forecast along with hot temperatures. /CR/
