KEY MESSAGES

Updated at 1015 PM CDT Sun Oct 18 2026

- Cool temperatures will persist tonight before a slight warming trend takes shape from early to midweek.

NEAR TERM

(Today) Issued at 310 AM CDT Mon Oct 19 2026

No major changes were made from the previous discussion. Temperatures remain on track to rise into the upper 60s to lower 70s this afternoon under clear skies with light, variable winds.

Previous Discussion: The Tennessee Valley will continue to be under the influence of subsidence from surface high pressure and upper ridging centered over the southern Plains. Although, a cutoff low looks to remain fairly stationary off the coast of Virginia and North Carolina. Overall, the dry, cool weather will persist overnight tonight and through the day on Monday. Clear skies will help aid temperatures to fall into the lower to mid 40s late tonight into Monday morning. Fog is not anticipated due to large dew point depressions. Make sure to grab at least a light jacket on your way out the door!

Even with dew points dropping into the 30s (and perhaps even lower if some Hi-Res guidance is correct), winds are expected to be light. Thus, while these dry conditions warrant at least caution when burning, there are no elevated fire weather concerns at this time. Otherwise, highs will top out in the upper 60s to lower 70s. Enjoy the pleasant weather!

SHORT TERM

(Monday Night through Wednesday) Issued at 1015 PM CDT Sun Oct 18 2026

Upper ridging will continue to dominate the central portion of the country through midweek. Even with the aforementioned low off the eastern seaboard, this feature looks to remain generally stationary. This will continue to let subsidence win out thanks to surface high pressure over much of the eastern CONUS and the upper ridging. This will result in continued dry weather (no rain) but also a slight warming trend through Wednesday. Expect lows generally in the mid 40s by Tuesday night and highs reaching the mid to upper 70s by Wednesday. This temperature trend looks to then extend into the long term as well (see below).

LONG TERM

(Wednesday Night through Sunday) Issued at 1015 PM CDT Sun Oct 18 2026

The upper ridge centered just to our west appears to become better amplified toward the later half of the week keeping above normal temperatures in place across the Great Plains and much of the Southeast. High pressure and large scale subsidence will continue to promote dry weather so much so that even cloud cover will be hard to come by until at least late in the weekend. Highs will reach the mid to upper 70s each afternoon, perhaps even reaching the 80 degree mark in some locations. Clear skies and calm overnight conditions will allow for good diurnal cooling, with lows in the 40s each night. Long term guidance becomes a bit more unclear regarding the upper level pattern toward the end of the weekend, so we will continue to focus on the above-normal daytime temperatures while we monitor trends for any potential fronts early next week.
