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

....SUMMARY...
Widely scattered, generally weak thunderstorm activity is possible
across parts of central California into the Great Basin, and across
parts of the central Great Plains, Sunday through Sunday night.

....Synopsis and Discussion...
An amplified upper trough will move east across the West Coast on
Sunday, with a strong backside speed max digging into the Four
Corners states into Monday morning. Minimal elevated instability is
forecast to develop primarily from southern NV into northern AZ and
southern UT, supporting isolated weak thunderstorms late.

To the east, a compact shortwave trough/upper low is forecast to
move quickly into the central Plains, with low pressure developing
over eastern CO into western KS. Given dry surface trajectories due
to a surface high to the east, minimal low-level moisture return
will occur. However, steep lapse rates especially during the late
afternoon and cool temperatures aloft will support scattered
thunderstorms, most prominent near the surface low over KS.
Therefore despite strong shear profiles with this otherwise
synoptically favorable system, severe weather is not expected.
