Meso low developing along and S of I-10 just W of Harris County moving E. Folks along and S of I-10 need to watch for some increasing threat of a quick tornado spin up across Central, Southern Harris, Ft Bent, Brazos and Galveston Counties on East.

Mesoscale Discussion 0180
NWS Storm Prediction Center Norman OK
0833 AM CST Tue Feb 14 2017

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.

Update from Jeff:

Powerful supercell moving ENE through central Fort Bend County showing strong rotation couplet at US 59/HWY 99. Large area of 60-80mph winds extends south across nearly all of Fort Bend County. Damage has been reported in both Wharton and Boling, and Pleak from this storm.

This cell will be moving over Sugar Land and then into SW/S Harris County. This is a serious supercell capable of producing damaging tornadoes.

Take immediate tornado precautions if under a tornado warning.
