MD 0782 CONCERNING SEVERE THUNDERSTORM WATCH 216…217…221… FOR WEST-CENTRAL/NORTH-CENTRAL TX
Mesoscale Discussion 0782
NWS Storm Prediction Center Norman OK
0837 PM CDT Fri May 12 2023
Areas affected...West-central/north-central TX
Concerning...Severe Thunderstorm Watch 216...217...221...
Valid 130137Z - 130330Z
The severe weather threat for Severe Thunderstorm Watch 216, 217,
221 continues.
SUMMARY...Slow-moving squall line will propagate southeast this
evening. Hail/wind remain possible.
DISCUSSION...Convection that developed along the dryline has
congealed into a larger MCS that extends from west-central into
northwestern TX. Expanding area of precipitation trails the leading
squall line that is beginning to surge a bit from SPS-ABI-north of
SJT. A reservoir of very strong instability (4000+ J/kg SBCAPE)
resides immediately downstream per FWD and OUN soundings. While a
weak cap was evident on 00z FWD sounding, this inhibition should not
preclude ongoing activity propagating into north-central TX later
this evening. Hail/wind remain possible.
