Mesoscale Discussion 0741 NWS Storm Prediction Center Norman OK 1000 PM CDT Thu May 09 2024 Areas affected...portions of far eastern Texas into central Louisiana and western Mississippi Concerning...Severe Thunderstorm Watch 225... Valid 100300Z - 100430Z The severe weather threat for Severe Thunderstorm Watch 225 continues. SUMMARY...The severe threat continues across Severe Thunderstorm Watch 225. Severe wind and hail should be the main threats over the next few hours. However, upscale growth into one or more MCSs is possible tonight, with severe winds becoming the primary threat. DISCUSSION...Multiple semi-discrete supercells and multicellular clusters persist across eastern TX into central MS amid a very unstable and highly sheared troposphere. As such, any storms that remain discrete will have the potential to continue producing severe hail in addition to damaging gusts. There is also some potential for upscale growth into one or more progressive, cold-pool-driven MCSs, as indicated by the 01Z run of both the HRRR and Warn-on-Forecast ensemble. Should this occur, focused corridors of severe winds could accompany these MCSs. At the moment, the best potential for upscale growth appear to be with the convective clusters in far eastern TX and perhaps with rapidly intensifying storms in north-central LA. ..Squitieri.. 05/10/2024 ...Please see www.spc.noaa.gov for graphic product...
