Areas affected...east Texas into Louisiana

Concerning...Tornado Watch 6...

Valid 110606Z - 110800Z

The severe weather threat for Tornado Watch 6 continues.

SUMMARY...The severe threat continues across eastern portions of
WW0006 with a downstream watch likely needed in the next hour.
Tornadoes and damaging winds will remain the severe threats.

DISCUSSION...A squall line stretching from the Ozarks to almost
Corpus Christi, TX continues to move eastward along a surface cold
front and leading edge of a strong upper-level trough. Strong flow
exists through the vertical profile, but much of the instability
resides above 700 mb with inversions present between 900-700 mb per
CRP and LCH soundings. Storms that have tried to develop ahead of
the line have struggled to intensify. However, the potential for
damaging winds remain possible given the ongoing squall line, strong
deep layer flow, including 50+ knots above 925 mb, and better
instability aloft. Additionally, tornadoes also remain possible
embedded within the line owing to favorable strong low-level veering
flow. Cell motion will remain northeastward with the overall line
propagation moving eastward. The line will likely continue into the
morning as it moves eastward.
