Mesoscale Discussion 0217 NWS Storm Prediction Center Norman OK 0900 PM CDT Sat Mar 15 2025 Areas affected...much of central Alabama Concerning...Tornado Watch 49... Valid 160200Z - 160400Z The severe weather threat for Tornado Watch 49 continues. SUMMARY...The risk of strong tornadoes persists over watch area, especially over central Alabama. DISCUSSION...In the wake of tornadic storms which went across the BMX radar, a residual region of outflow remains across parts of Shelby, Talladega, Chilton and Coosa counties. Meanwhile, a very large complex of storms is coming up from the southwest. Very strong inflow winds exist ahead of this complex, which will continue to feed these storms and possibly enhance lift along the residual outflow from the earlier storms. Given over 400 m2/s2 0-1 SRH, it is possible that any interaction with the boundary could result in a strong tornado. The environment remains favorable extending farther south as well, where a north-south confluence line is noted ahead of the primary cold front, and including the Wilcox County cell. ..Jewell.. 03/16/2025
