Valid 120457Z - 120700Z The severe weather threat for Tornado Watch 48, 49 continues. SUMMARY...An organized line of storms will overspread the region through 2-4 AM EDT, with some further increase in potential for tornadoes still possible. DISCUSSION...Although there has been a general warming of colder cloud tops associated with the convective system, a few embedded supercell structures persist, with occasional strengthening mesovortices along the eastward progressing convective outflow. Boundary-layer cooling with the loss of daytime heating has slowed in advance of the line, and low-level moistening continues in a narrow corridor across southwestern into central Alabama, including surface dew points increasing through the upper 60s to near 70F across and northeast of Selma. Likely in association with a broader weak migrating surface wave, the latest Rapid Refresh forecasts further strengthening of flow around 850 mb in excess of 40 kt across southern/eastern Alabama through 06-08Z. Given continuing inflow of air characterized by at least weak CAPE, additional enlargement of clockwise curved low-level hodographs could still support increasing potential for tornadoes during the next few hours. ..Kerr.. 03/12/2026 ...Please see www.spc.noaa.gov for graphic product...
