896 ACUS11 KWNS 032336 SWOMCD SPC MCD 032336 LAZ000-ARZ000-TXZ000-040130- Mesoscale Discussion 1155 NWS Storm Prediction Center Norman OK 0636 PM CDT Mon Jun 03 2024 Areas affected...Northeast Texas...Northern Louisiana...Southern Arkansas Concerning...Severe Thunderstorm Watch 385... Valid 032336Z - 040130Z The severe weather threat for Severe Thunderstorm Watch 385 continues. SUMMARY...An isolated wind-damage and hail threat will be possible with the stronger cells embedded in and ahead of a line segment from northeast Texas into southern Arkansas and northern Louisiana. Additional weather watch issuance remains uncertain. DISCUSSION...The latest mosaic radar imagery shows a linear MCS that is moving southeast at about 35 knots across the Ark-La-Tex. A pocket of strong instability is present ahead of the line, where surface dewpoints are in the 70s F and MLCAPE is estimated in the 2500 to 3500 J/kg range. The instability, along with strong large-scale ascent associated with a vorticity maxima and low-level convergence, will support the linear MCS for several more hours as it moves southeastward into the lower Mississippi Valley. The WSR-88D VWP at Shreveport has 0-6 km shear near 40 knots with directional shear in the lowest 2 km. This environment will continue to support an isolated wind-damage threat with the stronger segments along the leading edge of the line. Cells that form ahead of the line could also have a hail threat. ..Broyles.. 06/03/2024 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...JAN...LZK...SHV...HGX...FWD...
