Day 1 Convective Outlook 
NWS Storm Prediction Center Norman OK
1134 PM CDT Wed Aug 31 2022

Valid 011200Z - 021200Z

...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Organized severe thunderstorms are not forecast across the
contiguous United States through tonight.

...Synopsis...
A mid-level anticyclone will be centered over the Great Basin with a
ridge extending north through the Pacific Northwest.  Farther east,
a weakness in the ridge over KS/OK will evolve into a weak mid-level
trough over the western Ozark Plateau by daybreak Friday.  A
seasonably deep upper trough initially over New England will move
northeastward away from the region through the day.

Generally weak deep-layer flow/shear will tend to limit the threat
of organized convection through the period.  Northerly midlevel flow
across parts of the central/southern High Plains may support
sufficient deep-layer shear for some modest, transitory updraft
organization yielding perhaps a stronger storm or two.  However, the
coverage and expected intensity preclude low-severe probabilities.
Elsewhere, high-based convection could produce locally gusty winds
across parts of the northern Plains and also across Arizona.
Scattered to numerous thunderstorms will be possible across parts of
central/north TX into southern OK, and also across parts of the
Southeast, but these storms are expected to remain relatively
disorganized.
