Severe thunderstorms are possible on Friday from the lower Mississippi Valley into parts of the Mid-South and Southeast. ...Lower MS Valley into parts of the Southeast and TN/OH Valleys... In the wake of a negative-tilt shortwave trough and related surface low departing the Great Lakes region, a front will extend from the surface low southwestward along the lower/middle OH Valley into the Arklatex through the first half of the period. During this time, broad low-level warm advection amid a relatively moist air mass ahead of the front will support training thunderstorms beneath a belt of strong, front-parallel midlevel southwesterly flow. Despite poor deep-layer lapse rates and limited buoyancy, around 50 kt of effective shear may promote a couple strong to severe storms capable of damaging winds, isolated severe hail, and possibly a brief tornado into the afternoon hours. In the 21-03Z time frame, midlevel height falls accompanying a broad upstream trough will impinge on the frontal zone over the Mid-South vicinity. In response, a frontal wave will evolve into a surface low while tracking east-northeastward across the TN Valley during the overnight hours. Strengthening low-level warm-advection amid a plume of moist/uncapped air (middle/upper 60s dewpoints) will yield a quick uptick in thunderstorm coverage across the lower MS and TN Valleys. Around 50-60 kt of effective shear and enlarging low-level hodographs ahead of the low will conditionally favor a mix of organized clusters and semi-discrete supercell structures -- posing a risk of damaging winds and possibly a couple tornadoes. However, weak buoyancy and the potential for many storm interactions increase the overall conditionality of the tornado risk. ..Weinman.. 01/07/2026 $$ |
