Areas affected...Southeast Texas into southwest Louisiana

Concerning...Severe potential...Watch likely=20

Valid 051506Z - 051730Z

Probability of Watch Issuance...80 percent

SUMMARY...The severe weather threat is increasing across southeast
Texas this morning and will continue to increase into southwest
Louisiana by this afternoon.

DISCUSSION...A moist, uncapped airmass is in place across east Texas
and Louisiana ahead of a strong frontal boundary. Extensive
stratocumulus is in place this morning south of the front, but it is
expected to thin through the morning with strong surface heating and
destabilization expected by mid-day. As this occurs, more robust
convective development is expected along the front in east Texas.
Strong deep-layer shear and this strong instability should support
the potential for supercells with a threat for all severe hazards
including strong tornadoes. Despite the uncapped warm-sector, expect
open warm sector storm development to be minimal given the warm
800-650mb temperatures sampled by the SHV and LCH 12Z RAOBs with
primary storm development along and near the front where forcing is
maximized. Deep layer flow parallel to this front may result in a
messy storm mode, but the environment should support embedded
supercells capable of large hail, severe wind gusts, and tornadoes
(some which could be strong).
