Areas affected...Eastern Mississippi...Western Alabama

Concerning...Tornado Watch 335...337...

Valid 190348Z - 190545Z

The severe weather threat for Tornado Watch 335, 337 continues.

SUMMARY...A severe threat will likely continue over the next few
hours across eastern Mississippi and western Alabama. Tornadoes,
wind damage and isolated large hail will be possible.

DISCUSSION...High-resolution radar imagery from Jackson shows a
cluster of strong to severe storms located across central and
eastern Mississippi. The storms are located along the eastern edge
of a moderately unstable airmass, where surface dewpoints are in the
70s F and MLCAPE is estimated in the 2000 to 3000 J/kg range by the
RAP. Over the next couple of hours, the RAP moves a low-level jet
across eastern Mississippi and strengthens the jet to near 40 knots.
This will maintain strong low-level shear helping to continue the
tornado threat across eastern Mississippi. The threat should
gradually move eastward into western Alabama over the next couple of
hours. In addition, supercells will potentially be capable of
producing large hail and wind damage.
