Concerning...Tornado Watch 61...

Valid 252324Z - 260130Z

The severe weather threat for Tornado Watch 61 continues.

SUMMARY...The severe threat across the lower Mississippi Valley is
expected to gradually increase over the next few hours. Wind damage,
tornadoes and isolated large hail will be possible. New weather
watch issuance will likely be needed to the east of the current
watch.

DISCUSSION...High-resolution radar imagery from Jackson, MS and Fort
Polk, LA currently show a line of strong thunderstorms located
across central and northeastern Louisiana. A weakly unstable, but
moist airmass is present ahead of the line across much of the lower
Mississippi Valley, where surface dewpoints in the mid to upper 60s
F. On a broader scale, water vapor imagery shows a 80 to 100 knot
mid-level jet moving through south-central Texas. As this feature
ejects northeastward this evening, the mass response should be
maintained or may increase across the lower Mississippi Valley.
This, combined with strong deep-layer shear will likely create an
environment supportive of severe storms. Recent trends suggest that
the line has become somewhat more organized over the last hour. The
threat for wind damage, tornadoes and isolated large hail will be
possible, especially with cells that are more likely surface-based
to the east of the ongoing line.
