...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Severe thunderstorms are not expected on Sunday.

...Synopsis...
A deep upper trough will depart the East Coast Saturday night, with
a surface high settling over the Southeast on Sunday. To the west, a
shortwave trough will move east out of MT and toward the upper MS
Valley by Monday morning. A cold front in association with this
trough will quickly push across the northern and central Plains,
with a pre-frontal trough roughly from MN into MO and southwestward
into OK.

Given the southeastern surface high, moisture return will be limited
ahead of the Plains feature. However, cooling aloft and steepening
of lapse rates, as well as lift will allow for elevated instability
to develop into the upper MS Valley and Great Lakes, supporting
isolated to scattered thunderstorms overnight. Weak instability
should preclude any severe threat.
