Areas affected...central and southern Alabama

Concerning...Tornado Watch 89...

Valid 270531Z - 270600Z

The severe weather threat for Tornado Watch 89 continues.

SUMMARY...Severe risk has decreased recently, and may remain
sufficiently limited so as to not require new WW issuance beyond the
currently scheduled 27/06Z expiration time of WW 89.

DISCUSSION...Latest radar loop shows storms continuing across much
of central and parts of southern Alabama.  More nearly surface-based
storms are ongoing along the roughly west-to-east outflow/front,
while farther north, more decidedly elevated storms continue to
develop over east-central Mississippi, spreading repeatedly into
west-central/central Alabama.

Assessment of the current environment indicates ample CAPE
(most-unstable values 1000 to 2000 J/kg across the WW area), and
shear sufficient for organized updrafts with occasional mid-level
rotation.  However, with low-level flow largely veered, tornado
threat appears likely to remain limited/local over the next several
hours.  While marginal severe risk will linger with
stronger/longer-lived updrafts, overall risk appears sufficiently
limited so as to not require new WW issuance.
