Areas affected…southeast LA…far southern MS/AL

Concerning…Tornado Watch 2…

Valid 090103Z – 090300Z

The severe weather threat for Tornado Watch 2 continues.

SUMMARY…All severe hazards remain possible across Tornado Watch 2.
An additional isolated hail and wind risk may extend just outside of
the watch across parts of southern Mississippi/Alabama in the short
term.

DISCUSSION…Warm advection storms continue to shift northeast
across parts of southeast LA into southern MS/AL. This convection is
elevated and to the cool side of a warm front draped across southern
LA, and extending just offshore from MS/AL. Strong vertical shear,
as evident in very large and curved hodographs in regional VWP data,
will allow for some maintenance and organization of stronger
updrafts despite weakening instability with northward extent. These
stronger cells will pose some risk for hail given modest midlevel
lapse rates and favorable shear, as well as an isolated risk for
strong gusts.

A cold front and associated line of convection is currently oriented
from northeast to southwest LA, and will continue to shift east
overnight. A narrow warm sector currently confined to far southern
LA will continue to support tornado potential with any convection
that may develop ahead of the eastward advancing line of convection,
or within the line itself with any QLCS/mesovortex circulations. The
warm front will gradually lift northward overnight as a surface low
deepens as lifts northeast across the Lower MS/TN Valley. This will
allow higher-quality Gulf moisture moving into far southern MS/AL
and eventually the western FL Panhandle. Portions of WW 2, which
expires at 03z, may need to be included in a new tornado watch,
which would extend downstream into southern MS/AL and the western FL
Panhandle.
