Areas affected...Southeast Texas into southwestern Louisiana

Concerning...Severe potential...Watch unlikely=20

Valid 102301Z - 110030Z

Probability of Watch Issuance...20 percent

SUMMARY...A couple instances of large hail and locally severe wind
gusts will be possible for the next few hours.

DISCUSSION...The latest surface observations show a
west/east-oriented low-level confluence zone extending from
southeast TX into southwestern LA -- where a few thunderstorms are
attempting to strengthen. The earlier 18Z LCH sounding sampled steep
midlevel lapse rates atop a warm/moist PBL -- contributing to around
2500 J/kg MLCAPE. This buoyancy and an elongated mid/upper-level hodograph/strong venting aloft -- evident by eastward expanding
anvils on visible satellite imagery -- will conditionally support a
couple organized storms including supercell structures. Any storms
that can mature/intensify will pose a risk of large hail and locally
severe wind gusts for the next few hours. However, current thinking
is that many of these storms will struggle to mature owing to
midlevel dry air entertainment and overall weak forcing for ascent.=20

A watch is not expected for this activity in the near term, though
severe storms to the northwest may eventually move into parts of
southeast TX tonight -- and this will be addressed as needed.
