Areas affected...parts of south central Mississippi and adjacent
portions of western Alabama

Concerning...Tornado Watch 2...

Valid 100804Z - 101000Z

The severe weather threat for Tornado Watch 2 continues.

SUMMARY...The evolution of a supercell or two with increasing
potential for tornadoes, perhaps a strong one, east of Jackson
toward the Meridian MS vicinity through 3-5 AM CST. A new tornado
will probably be needed within the next hour or two.

DISCUSSION...There has been at least some recent increase in
thunderstorm development within the moist warm sector, near/north of
the McComb vicinity, where surface dew points near 70F appear to be
supporting moderate boundary-layer based CAPE as high as 1500 J/kg.=20
This appears to be occurring as a weak surface low migrates eastward
into west central Mississippi near Jackson.=20=20

During the next few hours, models suggest that strengthening
southwesterly flow around the 850 mb level (to around 40 kt) may
contribute to enlarging low-level hodographs along a remnant surface
baroclinic zone southeast of Jackson into areas near/south of
Meridian, coincident with boundary-layer destabilization associated
with a slow northward advection of the warmer and more moist warm
sector air. It appears this environment could become conducive to
substantive further thunderstorm intensification and organization,
including the evolution of a supercell or two accompanied by
increasing potential for tornadoes, perhaps a strong one.
