Areas affected...east-central Alabama into west-central Georgia

Concerning...Severe potential...Watch unlikely 

Valid 240839Z - 241115Z

Probability of Watch Issuance...20 percent

SUMMARY...An isolated damaging wind gust or brief tornado cannot be
ruled out over the next few hours.

DISCUSSION...A line of shallow thunderstorms with overall decreasing
lightning trends continues to push east along a cold front from
eastern AL into western GA. Surface analysis shows a narrow plume of
upper 60s F dewpoints ahead of the front, and also west of an
established stationary wedge front over GA. Two-hour pressure falls
were also in excess of 2 mb, indicative of strong southwesterly
low-level flow which may allow for some northeastward advancement of
the marginally unstable air.  Overall, the environment will become
less favorable for severe storms as they cross into the cooler air.
Until then, low-level shear and sufficient instability may support
periodic strong wind gusts or even a brief QLCS tornado along the
cold front.
