FOR TEXAS BIG BEND INTO PECOS VALLEY\n\n\n\n\n    Mesoscale Discussion 0810\n    NWS Storm Prediction Center Norman OK\n    0635 PM CDT Wed May 20 2026\n\n    Areas affected...Texas Big Bend into Pecos Valley\n\n    Concerning...Severe Thunderstorm Watch 237...\n\n    Valid 202335Z - 210130Z\n\n    The severe weather threat for Severe Thunderstorm Watch 237\n    continues.\n\n    SUMMARY...A small cluster of storms continues to pose some risk for\n    severe hail and wind, but this potential probably will diminish\n    while spreading toward the San Angelo vicinity through 8-9 PM CDT.\n\n    DISCUSSION...Strongest storms have been maintained on the\n    northeastern flank of convective outflow slowly propagating off the\n    higher terrain, in the presence of strongly sheared (due to veering\n    of winds with height) but weak southwesterly deep-layer mean flow on\n    the order of 15-20 kt.  This is where northeasterly surface winds to\n    the cool side of a weakening surface front may be enhancing\n    convergence along the outflow, and low-level warm advection above\n    the front may be still maximized.  However, latest guidance suggests\n    that this forcing may begin to weaken within the next couple of\n    hours, resulting in diminishing convective intensities, if an influx\n    of less unstable updraft does not weaken convection sooner.\n\n    ..Kerr.. 05/20/2026\n\n    ...Please see www.spc.noaa.gov for graphic product...\n\n    ATTN...WFO...SJT...MAF...\n\n    LAT...LON   30620214 31030196 31090081 30320167 30030245 30620214\n\n    MOST PROBABLE PEAK TORNADO INTENSITY...UP TO 90 MPH\n    MOST PROBABLE PEAK WIND GUST...UP TO 60 MPH\n    MOST PROBABLE PEAK HAIL SIZE...1.50-2.50 IN\n\n\n\nRead more",
