Mesoscale Discussion 1160 NWS Storm Prediction Center Norman OK 0349 AM CDT Tue Jun 04 2024 Areas affected...Southeast OK...northeast TX...and far southwest AR Concerning...Severe Thunderstorm Watch 388... Valid 040849Z - 041015Z The severe weather threat for Severe Thunderstorm Watch 388 continues. SUMMARY...Strong to locally severe wind gusts remain possible with a short linear cluster moving southeast in southeast Oklahoma. Spatiotemporal uncertainty exists regarding this threat downstream for an additional severe thunderstorm watch. DISCUSSION...A short linear cluster has surged southeastward into southeast OK as advertised by the consensus of 00Z CAM guidance. Despite riding along the MLCAPE gradient with a feed of ample buoyancy amid a 50-kt southwesterly low-level jet per FWS/SRX VWP data, measured surface wind gusts have held in the 35-55 mph range across several OK-Mesonet and ASOS/AWOS sites. Indeed, the surface cold pool has been relatively weak at 4-6 F of cooling in the wake of the cluster. Still, an embedded swath or two of lower-end severe gusts may occur, especially near the apex of the cluster across the rest of southeast OK. Confidence is lower on the degree of wind damage threat into northeast TX given overall cloud top warming and lack of stronger winds measured in OK thus far. At least a localized damaging wind threat should exist outside of WW 388 through sunrise. ..Grams/Thompson.. 06/04/2024 ...Please see www.spc.noaa.gov for graphic product...
