Areas affected...Eastern AL...Western GA
Concerning...Tornado Watch
498...
Valid 102054Z - 102230Z
The severe weather threat for Tornado Watch 498 continues.
SUMMARY...The threat for brief tornadoes will continue into the
early evening as convection spreads slowly eastward.
DISCUSSION...At 2045Z, a band of convection continues across eastern
AL into western GA. Weak rotation has occasionally been noted with
the stronger discrete cells. While instability remains weak across
the region (MLCAPE generally less than 500 J/kg), 0-1 km SRH of
200-400 m2/s2 will support a brief tornado threat with the stronger
convective elements, especially with any discrete elements in closer
proximity to the effective warm frontal zone, where low-level flow
remains backed. Some threat may spread slightly east of the watch
with time, as additional development occurs ahead of the main
convective band. Local watch extension may be needed at some point
depending on the intensity of any new development.
