Areas affected...parts of southeastern Texas into central and
southwestern Louisiana
Concerning...Tornado Watch 634...
Valid 282221Z - 290015Z
The severe weather threat for Tornado Watch 634 continues.
SUMMARY...Scattered strong thunderstorms, including a couple of
supercells posing risk for severe hail and potential to produce a
tornado or two, will continue developing southeastward across the
region through 7-8 PM CDT, before diminishing.
DISCUSSION...The southeastward advancing cold front appears to be
rapidly overtaking the preceding narrow corridor of stronger
instability across the mid/upper Texas coastal plain into the Texas
Piney Woods. However, model output suggests that boundary-layer
moisture advection and southeastward spreading mid/upper forcing for
ascent will support sufficient destabilization to maintain vigorous
thunderstorm activity east-southeastward into and through much of
southwestern and portions of central Louisiana during the next few
hours.
This is likely to include continuing generally discrete thunderstorm
activity. Low-level hodographs are still rather modest to weak, but
strong deep-layer shear is more than sufficient for supercells
posing a risk for severe hail, with at least some potential to
produce a tornado or two into the 00-01Z time frame.
