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.
