Areas affected...Parts of southeast Texas

Concerning...Severe Thunderstorm Watch 246...

Valid 270721Z - 270915Z

The severe weather threat for Severe Thunderstorm Watch 246
continues.

SUMMARY...Embedded strong to severe gusts remain possible with an
eastward-moving MCS. A downstream watch issuance is not expected.

DISCUSSION...The latest radar data from KHGX indicates an MCS
tracking eastward across southeast TX at around 30-35 kt. Given the
well-established cold pool, around 40 kt 0-6 km shear (per VWP
data), and moist inflow (lower 70s dewpoints) for this system,
strong to locally severe gusts (50-60 mph) will remain possible as
it continues eastward over the next couple hours. However, given the
orientation of the midlevel trough and accompanying midlevel flow,
weakening upper-level support and increasingly line-parallel
deep-layer shear should tend to limit convective intensity with
eastward extent -- especially given the lack of a stronger low-level
mass response. Therefore, a downstream watch is not expected.
