Mesoscale Discussion 0388 NWS Storm Prediction Center Norman OK 0727 PM CDT Mon Apr 08 2024 Areas affected...portions of northwest Texas Concerning...Severe Thunderstorm Watch 91... Valid 090027Z - 090200Z The severe weather threat for Severe Thunderstorm Watch 91 continues. SUMMARY...The threat for large hail will increase through the evening. DISCUSSION...Storms have formed and moved north of a frontal zone across Northwest Texas. The long, straight hodograph, evident on the LBB VWP) supports splitting supercells, with a few already evident in that region. In fact, the only hail report thus far (1.75") came from a left-moving supercell. Expect this cluster of supercells to continue northeast and gradually intensify through the evening as instability increases with northwestward moisture advection. Limited instability to the north of this cluster should limit the longevity of left-movers, with the hail threat remaining mostly south of the Red River. Watch 91 will be cleared in the wake of this cluster of supercells. An additional threat for large hail is expected overnight as stronger ascent overspreads the southern Plains, but this will be handled with a separate watch, if necessary. ..Bentley/Hart.. 04/09/2024 ...Please see www.spc.noaa.gov for graphic product...
