The severe weather threat for Tornado Watch 32 continues.
SUMMARY...The risk of damaging winds and a couple mesovortex
tornadoes should increase during the next few hours.
DISCUSSION...Latest radar data from KPOE shows an organizing
north-south-oriented line segment tracking east-northeastward at
around 50 mph over far southwest MS into southeast LA. Lower/middle
60s dewpoints should continue to yield surface-based inflow for this
line, while 50+ kt of midlevel flow oriented oblique to the
leading-edge gust front should favor a continued organized/linear
mode. Additional upscale growth/storm mergers downstream along with
a strengthening pre-frontal low-level jet should support an
increasing risk of damaging gusts. 50-70 mph gusts (some locally
higher) are possible with any bowing/forward-propagating segments in
the line. In addition, favorably curved low-level hodographs (per
DGX VWP data) could also support a couple mesovortex tornadoes --
especially in parts of the line that become oriented more SSE-NNW.
