...NO THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Thunderstorms are not expected across the USA Sunday.

...Synopsis...
A low amplitude, mostly zonal, mid-level flow regime will persist
across the US Sunday, as weak ridging over the central states shifts
eastward. A shortwave trough, embedded within strong westerly flow
aloft, will eject into the central Plains as a second, weaker trough
approaches the West Coast early Monday. A lee low should steadily
deepen over the central Plains and Midwest ahead of the advancing
shortwave trough, while high pressure remains steady over the
Southeast.

Weak moisture return is expected across parts of the Plains and
ArkLaTex as the low deepens and moves east. However, low and
mid-level lapse rates will remain poor, with strong inhibition
negating thunderstorm potential.  Elsewhere, little to no buoyancy
is expected across the CONUS outside of the near coastal waters of
WA and OR. Given the poor lapse rates and weak inland moisture
advection, any low-topped thunderstorms that do develop are expected
to remain transient and offshore.
