Mesoscale Discussion 1087 NWS Storm Prediction Center Norman OK 0759 PM CDT Thu May 30 2024 Areas affected...Southeast TX...Western LA Concerning...Severe Thunderstorm Watch 353...355...356... Valid 310059Z - 310230Z The severe weather threat for Severe Thunderstorm Watch 353, 355, 356 continues. SUMMARY...Locally damaging winds and marginally severe hail will be noted along the leading edge of southeast-moving MCS this evening. DISCUSSION...Long-lived MCS has matured into an expansive cluster of storms across much of East TX into western LA. Leading edge of this MCS is surging across the Sabine River over De Soto Parish, arcing southwest to near CLL. An MCV may be forming within the expanding precip shield, southeast of GGG. However, the leading QLCS is expected to advance across the remainder of Southeast TX, including the upper Coastal Plain, into southwest LA later this evening. Hail may approach 1 inch with this squall line, along with locally damaging winds. Some risk for larger hail continues with more isolated storms back into south-central TX. ..Darrow.. 05/31/2024 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...LCH...SHV...HGX...
