Areas affected...Eastern Alabama into northwest Georgia

Concerning...Severe potential...Watch possible=20

Valid 032134Z - 032330Z

Probability of Watch Issuance...40 percent

SUMMARY...A squall line developing across northeast to central
Alabama may pose a damaging wind threat through the early evening
hours. Watch issuance is possible if convective trends continue to
increase.

DISCUSSION...An organized squall line continues to develop across
northeast to central AL as a cold front pushes into the region.
Earlier cloud cover across the warm sector has begun to erode over
the past hour or so, resulting in temperatures warming into the mid
to upper 70s with a corresponding reduction in inhibition and
increasing MLCAPE (upwards of 500-1000 J/kg per recent mesoanalysis
estimates). The improving thermodynamic environment, coupled with
35-40 knots of deep-layer shear per regional VWPs, is supporting an
overall uptick in convective intensity based on GOES IR imagery and
MRMS echo tops. Lingering clouds and gradually diminishing diurnal
insolation suggest that the thermodynamic environment is likely at
its zenith, so the overall convective intensity remains somewhat
uncertain heading into the late afternoon/early evening. Regardless,
based on current observations, this squall line and embedded
supercells should be sufficient to produce damaging gusts,
occasional large hail, and perhaps embedded circulations where line
segments can become meridionally oriented and more orthogonal to the southwesterly low-level shear vectors. Trends will continue to be
monitored for the need for a watch.
