Areas affected...Parts of southeast Texas



Concerning...Severe Thunderstorm Watch 631...



Valid 250816Z - 251015Z



The severe weather threat for Severe Thunderstorm Watch 631

continues.



SUMMARY...Damaging wind gusts and a brief/embedded tornado or two

remain possible in Severe Thunderstorm Watch 631 -- especially in a

west-east corridor extending from parts of Harris County to

Jefferson County through around 11Z.



DISCUSSION...The latest radar data from KHGX and especially TIAH

show several embedded/transient mesovortex structures within the

convective line moving across southeast TX. As the line continues

eastward, the combination of lower 70s dewpoints and enhanced

low-level hodograph curvature (around 200 m2/s2 0-1km SRH per VWP

data) will continue to support these transient/enhanced embedded

circulations -- posing a risk of damaging gusts and possibly a brief

tornado or two. The most favorable corridor appears to extend from

parts of Harris County eastward to Jefferson County through around

11Z.
