Threat for Damaging Winds & a Brief Tornado Remains Possible Ahead of the Front
Here is the latest from the SPC’s Mesoscale Discussion:
SUMMARY… Storms moving out of Tennessee and Alabama may continue to pose a damaging wind and brief tornado threat.
DISCUSSION… A long-lived line of storms currently extends from far eastern TN into northeast AL, with QLCS structures observed on radar with a brief tornado possibly occurring in DeKalb County, AL.
Surface analysis shows mid 60s F dewpoints have spread into the Atlanta area, with low 60s F approaching western NC. This is resulting in sufficient SBCAPE to sustain a damaging wind and tornado risk, as shear remains strong. 0-1 SRH of 250-300 m2/s2 currently resides ahead of the line of storms, and strongly favors low-level rotation. As such, the QLCS tornado and wind risk is expected to continue eastward, and a new watch may be necessary soon.
