Mesoscale Discussion 1239 NWS Storm Prediction Center Norman OK 1012 PM CDT Wed Jul 15 2020 Areas affected...Northeast NM...OK/TX Panhandle Region Concerning...Severe Thunderstorm Watch 377... Valid 160312Z - 160515Z The severe weather threat for Severe Thunderstorm Watch 377 continues. SUMMARY...Gusty winds and marginally severe hail will accompany convection across portions of the southern High Plains the next several hours. DISCUSSION...Convection that developed off the higher terrain of NM and southern CO has progressed about 100 miles downstream where some organization is currently observed. MCS has evolved along the NM/TX border with the leading squall line advancing northeast at roughly 20 kt. This activity has struggled to produce more than isolated severe wind gusts over the last few hours, possibly due to outflow racing up to 15 miles ahead of the precip shield. Even so, strengthening LLJ across the TX South Plains should allow this activity to begin turning more east along the instability axis, characterized by MLCAPE of 1500-2000 J/kg. Gusty winds remain the primary threat. ..Darrow.. 07/16/2020 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...AMA...ABQ...
