Areas affected...Upper TX Coast into southwest LA

Concerning...Severe Thunderstorm Watch 359...

Valid 311357Z - 311530Z

The severe weather threat for Severe Thunderstorm Watch 359
continues.

SUMMARY...An isolated damaging-wind threat could spread into parts
of extreme southwest Louisiana later this morning.

DISCUSSION...The northern portion of a long-lived QLCS is moving
slowly eastward near the upper TX coast this morning, with the
stronger portion of the QLCS currently moving offshore farther
southwest. The 12Z LCH sounding depicted moderate MUCAPE, but also
near-surface stability and only modest low-level flow. Somewhat
warmer and more unstable conditions are noted downstream near the
immediate coast, where some increasing cumulus has been noted. In
areas where continued modest pre-storm heating can occur, some
damaging-wind threat could persist through mid morning, though the
environment is expected to remain only marginally favorable for
organized convection.=20

With the short-term threat expected to remain relatively confined to near-coastal areas of southwest LA, new watch issuance is currently
considered unlikely.
