NEAR TERM

(Tonight) Issued at 239 PM CDT Mon Sep 15 2025

Dry weather will continue this afternoon as an upper level ridge continues to try to shift eastward into our area. CAMs continue to hint at a very low chance of a stray shower or thunderstorm in the area this evening, however, confidence in this occurring remains low. Overnight, lows are forecast to drop into the low to mid 60s under mostly clear skies.

SHORT TERM

(Tuesday through Thursday) Issued at 1022 AM CDT Mon Sep 15 2025

Through the week, we will remain in a blocking pattern as low pressure lingers off the Southeast Coast coupled with a ridge continuing to stretch across the Great Lakes as low pressure in the northern Plains attempts to shift eastward. As this continues, conditions throughout the Tennessee Valley should remain mostly dry. Highs during this time are forecast to reach the mid 80s to low 90s, with a gradual warming pattern through the week. Overnight lows are forecast to drop into the low to mid 60s. While heat indices are forecast to remain in the upper 80s to mid 90s, action should still be taken to mitigate heat exhaustion. Be sure to stay hydrated, take frequent breaks if working outdoors, and never leave any pets or people in vehicles.

LONG TERM

(Thursday through Sunday) Issued at 929 PM CDT Sun Sep 14 2025

The blocking pattern will finally break down during the latter half of the work week as the Mid Atlantic low weakens and lifts northward. High pressure will keep conditions dry for Thursday, but low chances of showers and storms return on Friday and into the weekend as the other trough in the blocking pattern slides into the Plains. Its surface low will lift into the Midwest, with the associated cold front sliding into the Mid MS Valley. At this time, it doesn't look like the front will make it into the TN Valley but stay close enough to keep a low chance (20-30%) in the forecast through the weekend. Warmer than normal highs will linger into Saturday with temps in the upper 80s to lower 90s. They will cool a tad on Saturday, remaining below 90 degrees.

AVIATION

(18Z TAFS) Issued at 102 PM CDT Mon Sep 15 2025

Prevailing conditions at the HSV/MSL terminals will remain VFR throughout the upcoming forecast period, featuring few-sct high- based Cu (in the 5-10 kft layer) beneath a gradually increasing coverage of Ci and a lgt/vrbl-light SSE wind. Although rain and thunderstorms (which impacted MSL earlier this morning) have since spread southwestward, redevelopment of convection (associated with the same upper-lvl disturbance) may occur this afternoon/evening, but should be most concentrated west of the AL- MS border. Another similar disturbance aloft will travel in the northeasterly flow around an upper low over southeastern NC, and may initiate a few convective showers along the Cumberland Plateau later this afternoon, which could shift south-southwestward and may impact portions of northeast AL overnight. However, chances for TSRA will likely not begin to increase at the terminals again until Tue aftn, and for this reason we will not mention any precipitation in the TAFs attm.
