Watch issuance appears unlikely at this time. DISCUSSION...Isolated thunderstorms are ongoing across west-central Alabama and southern Georgia as of 1800 UTC, with additional development expected along a remnant outflow boundary and within pockets of modestly enhanced surface convergence across the region through the afternoon. High PW (1.75-2.0+ inches) and steepening low-level lapse rates will foster at least an isolated risk for damaging wind gusts with water-loaded downbursts; however, marginally cooler temperatures (low 90s F) and modestly weaker low-to-mid level flow (less than 15-20 kts per area VWPs) suggest the coverage and magnitude of the severe risk may be somewhat more limited compared to areas farther west. Given this, the need for a Severe Thunderstorm Watch is more uncertain but appears unlikely at this time. Trends will continue to be monitored, and a watch could be considered should a corridor of greater damaging wind gust potential become evident. ..Chalmers/Smith.. 08/21/2026 ...Please see www.spc.noaa.gov for graphic product...
