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. ..Barnes.. 06/04/2024 ...Please see www.spc.noaa.gov for graphic product...
