MD 1202 CONCERNING TORNADO WATCH 355… FOR EASTERN PORTIONS OF THE TEXAS SOUTH PLAINS
Mesoscale Discussion 1202 NWS Storm Prediction Center Norman OK 0919 PM CDT Wed Jun 21 2023 Areas affected...eastern portions of the Texas South Plains Concerning...Tornado Watch 355... Valid 220219Z - 220415Z The severe weather threat for Tornado Watch 355 continues. SUMMARY...Risk for large hail and damaging wind gusts, and possibly a tornado, will likely continue for the next couple of hours. DISCUSSION...Latest radar loop shows a cluster of severe storms moving southward across the eastern half of the South Plains region of Texas -- within central portions of Tornado Watch 355. The lead supercell is in the process of merging with what was a second cell, and while a bit disorganized at present, may reorganize into one large, rotating storm. This cluster of storms is moving within the axis of greatest instability (4500 J/kg mixed-layer CAPE), suggesting potential for storms to shift south-southeastward out of the bounds of WW 355 in the next hour and a half or so. With that said, CAMs continue to suggest diurnal weakening will commence over the next couple of hours, so it remains uncertain how much risk will extend south/southeast of the existing watch. Still, we will continue to monitor convective evolution, and potential that a new, small watch may be required across areas south of WW 355 and north of San Angelo. ..Goss.. 06/22/2023 ...Please see www.spc.noaa.gov for graphic product...
