MD 1165 CONCERNING SEVERE THUNDERSTORM WATCH 391... FOR SOUTHERN LOUISIANA AND SOUTHERN MISSISSIPPI

Mesoscale Discussion 1165
NWS Storm Prediction Center Norman OK
0455 PM CDT Tue Jun 04 2024

Areas affected...Southern Louisiana and southern Mississippi

Concerning...Severe Thunderstorm Watch 391...

Valid 042155Z - 042330Z

The severe weather threat for Severe Thunderstorm Watch 391
continues.

SUMMARY...A few damaging wind gusts up to 60-65 mph and localized
instances of marginally severe hail near 0.75-1.25" in diameter may
continue to accompany a linear complex of thunderstorms through this
evening.

DISCUSSION...Latest radar and satellite imagery show an MCS
progressing east-southeastward across portions of southern LA and
southern MS. A moderately unstable air mass remains in place ahead
of this system, where diurnal heating has resulted in surface
temperatures climbing into the upper 80s and 90s, with dewpoints
generally in the mid 70s. Recent trends from the POE VAD profiler
indicate westerly 0-3 km shear has increased to around 50 kt over
the past 30 minutes behind the system. This may support an
increasing opportunity for bowing segments, and damaging wind gusts,
oriented north-south on the eastern flank of the complex, and a
general eastward progression into south-central/southeastern MS over
the next 1-2 hours. In addition, brief instances of marginally
severe hail will be possible within any of the more robust updrafts.
