Areas affected...Portions of the Upper TX Coast and vicinity

Concerning...Tornado Watch 32...

Valid 141433Z - 141500Z

The severe weather threat for Tornado Watch 32 continues.

SUMMARY...The most intense segment of a quasi-linear convective
system will move through locations near and south of the Houston
area through 16Z. Damaging winds and a few tornadoes are possible.

DISCUSSION...The most prominent rear-inflow surges and flanking
mesovortices attendant to a broader squall line crossing southeast
TX will move through areas near/south of the Houston area through
16Z. The HGX VAD wind profile indicates ample low-level SRH (around
250-300 m2/s2 in the 0-1-km layer), aided by veering winds with
height. Sufficient moisture influx ahead of the line (dewpoints in
the middle 60s) will support enough buoyancy for a continued
damaging wind risk, and line-embedded circulations may pose a
tornado risk with this most intense portion of the convective
system. This could affect the Houston area and locations to the
south.
