MD 0256 CONCERNING SEVERE THUNDERSTORM WATCH 51… FOR EAST-CENTRAL MS INTO CENTRAL/NORTHEAST AL AND NORTHWEST GA
Mesoscale Discussion 0256
NWS Storm Prediction Center Norman OK
0745 AM CDT Fri Mar 15 2024
Areas affected…East-central MS into central/northeast AL and
northwest GA
Concerning…Severe Thunderstorm Watch 51…
Valid 151245Z – 151415Z
The severe weather threat for Severe Thunderstorm Watch 51
continues.
SUMMARY…A localized damaging-wind threat may persist through the
morning.
DISCUSSION…A long-lived QLCS is gradually moving eastward across
parts of MS/AL into northwest GA this morning. Within the larger
QLCS, shorter line segments have occasionally taken on a north-south
orientation through the early morning, accompanied by some increase
in organization and damaging-wind potential. This general trend may
persist into mid morning, with an isolated damaging-wind threat
accompanying the stronger line segments that do not get undercut by
outflow.
Some threat may spread outside of WW 51 into northwest GA, though
the need for downstream watch issuance is uncertain, due to weaker
instability with northeastward extent (as noted in the 12Z FFC
sounding and objective mesoanalyses). Farther southwest, some uptick
remains possible from east-central MS into central AL, where MLCAPE
of 500-1000 J/kg and favorable deep-layer shear remain in place this
morning. Local watch extension may need to be considered for parts
of MS/AL, depending on short-term convective trends.
