Mesoscale Discussion 1147

Areas affected...much of western into northwestern
Alabama...southern Middle Tennessee

Concerning...Severe potential...Watch unlikely=20

Valid 181133Z - 181330Z

Probability of Watch Issuance...20 percent

SUMMARY...A few strong wind gusts will be possible as a broken line
of storms moves eastward into the area, but a watch is not expected.

DISCUSSION...Numerous storms persist this morning over much of MS
and extending northward into western TN, with much of the activity
associated with a long-lived area of outflow. Instability remains
strongest over MS, but a moderately unstable air mass does exist
into western/southwestern AL where surface temperatures are warmer.

The primary risk with these storms will be strong to locally
damaging gusts, owing to the continuous storm regeneration along the
leading outflow. Given the moderate instability and moist air mass,
the larger clusters of storms may produce localized wind damage. The
hail threat should remain low with most of these storms owing to the
multicellular storm mode. Given the isolated nature of the expected
severe gusts, a watch is not currently expected.
