Areas affected...southern Mississippi...southwest Alabama...western
Florida Panhandle...parts of southeastern Louisiana
Concerning...Tornado Watch 472...
Valid 291504Z - 291900Z
The severe weather threat for Tornado Watch 472 continues.
SUMMARY...Tornadoes will remain possible with the stronger cells
within outer convective bands.
DISCUSSION...An initial band of storms continues to move northward
across southern MS, southern AL, and the western FL Panhandle. The
strongest cells continues to be across southern AL and into FL where
there is access to more favorable boundary-layer theta-e. Farther
northwest into MS and curling southwest across the LA state line, a
region of cooler air exists which may be reducing tornado potential temporarily.
With time, higher theta-e is expected to shift westward across
southern MS and much of southeastern LA, along with increasing SRH.
Additional bands of convection are expected to develop into the
area, most likely emanating from the instability axis currently near
and south of the AL/FL Panhandles where more robust bands of
convection are currently situated.
