927 ACUS11 KWNS 310413 SWOMCD SPC MCD 310413 MSZ000-LAZ000-310545- Mesoscale Discussion 1088 NWS Storm Prediction Center Norman OK 1113 PM CDT Thu May 30 2024 Areas affected...Lower Mississippi Valley Concerning...Severe Thunderstorm Watch 357... Valid 310413Z - 310545Z The severe weather threat for Severe Thunderstorm Watch 357 continues. SUMMARY...Gusty winds and marginally severe hail will be noted with a squall line as it progresses across the lower Mississippi Valley. DISCUSSION...Long-lived MCS that developed over the southern Plains of TX has matured and advanced across most of LA late this evening. Latest diagnostic data suggests a weak short-wave trough has progressed into AR/LA and this feature appears partly responsible for the expansive nature/organization of the complex. Over the next few hours the leading squall line will shift east of the primary instability axis and gradual weakening is expected. Until then, gusty winds are the main risk. ..Darrow.. 05/31/2024 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...JAN...LIX...LCH...SHV...
