CORRECTED FOR DISCUSSION TEXT

The severe weather threat for Tornado Watch 573, 574, 575 continues.

SUMMARY...Severe/tornado risk continues across portions of WW
573/574/575.

DISCUSSION...Widespread thunderstorms continue across the Mid South
and central Gulf Coast states.  The bulk of the ongoing
severe/tornado risk persists mainly across the central third or so
of Mississippi into west-central Alabama.=20=20

Across this region, a moist *airmass* persists, ahead of the
advancing cold front that is now crossing Arkansas/East Texas.=20
Meanwhile, low-level shear has increased a bit over the past hour or
so, as flow in the 1 to 2km layer gradually strengthens.

While storms have decreased a bit with respect to organization in
general over the past hour -- likely due to modest after-dark
stabilization, some increase is noted within streamers of showery
convective cells south of the main convection -- i.e. across
southeastern Louisiana and southern Mississippi -- including hints
of weak rotation. This may be reflective of the aforementioned
increase in low-level shear, which overall suggests that the
potential for tornadoes continues across the area.
