.DISCUSSION... (Tonight through next Saturday) Issued at 1105 PM CDT Sat Sep 6 2025
A quiet and clear night is underway across the Mid-South. Temperatures are running 5 to 10 degrees cooler than 24 hours ago as of 9:30 PM. Clear skies, saturated surfaces, and calm winds is a nice radiational fog setup. Patchy to locally dense fog is expected across West Tennessee, near the Tennessee River, and into extreme north Mississippi.
An area of high pressure will continue to sink south and eventually encompass the entire region in the coming days. This will be responsible for unseasonably cool nights and mornings, but pleasant fall-like conditions during the day with highs in the low to mid 80s. Monday morning will be the coolest morning with lows dipping below 50 degrees for areas near the Kentucky and Missouri borders. This area of high pressure will bring plentiful dry air suppressing rain chances and keeping humidity at bay.
By Tuesday, the ridge will heighten and build for the rest of the work week. This will bring our temperatures back into the upper 80s and lower 90s. Long term deterministic and ensemble solutions continue to keep this ridge over the area late into next week. The long presence of strong ridging will keep temperatures elevated and continue to keep rain chances at a minimum. This is not good news for ongoing drought conditions and heightens dangerous wildland fire conditions.
