Valid 071200Z - 081200Z

....NO SEVERE THUNDERSTORM AREAS FORECAST...

....SUMMARY...
Severe weather is not expected across the U.S. on Wednesday.

....Discussion...
While a deep upper vortex remains over north-central Canada and a
stout ridge persists over the Gulf of Mexico, a western U.S. trough
-- embedded in the fast southwesterly flow field between the two
aforementioned features -- will cross the Four Corners/southern
Rockies on Wednesday.

As this occurs, a surface baroclinic zone -- initially stretching
from northern and western Texas northeastward to the central
Appalachians -- will shift eastward and southeastward across the
eastern and southeastern states, respectively.  Farther west, some
northward drift of the front into Oklahoma is expected overnight,
ahead of the advancing western upper system.

Showers and occasional thunderstorms are expected to occur, within
the general vicinity of the front.  However, instability is forecast
to be quite weak.  This factor, combined with a much of the
convection over the south-central region being north of the front
with a low-level warm-advection regime, suggests that risk for
stronger storms should remain minimal at best, through the period.

...Goss.. 12/06/2022
