NWS Storm Prediction Center Norman OK
1124 PM CST Sun Nov 27 2022
Valid 281200Z - 291200Z
...NO THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Organized thunderstorms are not expected today.
...Synopsis...
A mid-level trough will deepen across the Interior West while a
surface low begins to develop across the Plains states today. Very
cold mid-level temperatures (-30C to -40C at 500 mb) will overspread
portions of the Pacific Northwest into northern parts of the Great
Basin through the period. While buoyancy should remain scant across
the Interior West, the very cold temperatures aloft may promote a
lightning flash or two if any above-freezing parcels can be lifted
to their LFC, introducing both liquid and ice species in the
cloud-bearing layer. Gulf of Mexico moisture should gradually advect
northward in response to surface lee troughing across portions of
the Southern Plains into the Lower MS Valley, particularly towards
the later half of the period. However, negligible upper support and
lack of buoyancy should limit organized thunderstorm potential up to
12Z Tuesday.
