Areas affected...Portions of central AL
Concerning...Tornado Watch 149...
Valid 042310Z - 050015Z
The severe weather threat for Tornado Watch 149 continues.
SUMMARY...The greatest damaging wind and isolated tornado threat
should focus across a small part of central Alabama in the short
DISCUSSION...Recent radar imagery from KBMX and KMXX show enhanced
velocities associated with a small segment of the larger bowing
complex across southern/central AL. This area will likely have the
greatest potential for severe/damaging wind gusts in the next hour
or two. An outflow boundary is also evident extending southeastward
from the most intense portion of the bow across southeastern AL. Any
isolated tornado threat may focus near this outflow boundary, as
low-level flow is backed to east-northeasterly, locally enhancing
0-1 km SRH.
