Mesoscale Discussion 0985 NWS Storm Prediction Center Norman OK 1143 PM CDT Sun May 25 2025 Areas affected...Parts of central/south AL into west-central GA Concerning...Severe Thunderstorm Watch 328... Valid 260443Z - 260615Z The severe weather threat for Severe Thunderstorm Watch 328 continues. SUMMARY...Wind-damage potential may persist into the early morning. DISCUSSION...A rather long-lived and extensive QLCS continues to move across parts of central AL late this evening. An earlier bowing segment across northern AL has weakened, and both the northernmost and southernmost portions of the QLCS are tending to sag southeastward with time, with the gust front advancing ahead of the deeper convection. The most vigorous part of the QLCS at the moment is across west-central AL, where the line has taken on a more north-south orientation and is currently surging eastward. Favorable low-level moisture and moderate downstream buoyancy may help to sustain this portion of the line and the attendant wind-damage threat in the short term. The longevity of the organized severe threat with this QLCS is uncertain, with low-level flow and deep-layer shear expected to remain modest at best. However, if the eastward-surging line segment can keep pace with the outflow, then some wind-damage threat could spread into east-central/southeast AL and west-central/southwest GA with time. Cells developing ahead of the line in the vicinity of the remnant outflow could also be strong to marginally severe into the early morning. Potential for any downstream watch issuance will depend on trends regarding QLCS organization and the downstream environment over the next 1-2 hours. ..Dean/Mosier.. 05/26/2025 ...Please see www.spc.noaa.gov for graphic product...
