...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
A few thunderstorms are possible along a portion of the coastal
Pacific Northwest tonight.

...Discussion...
A progressive flow regime will reside across the contiguous United
States today to the north of a low-latitude, mid-level low over
northwestern Mexico. In the Pacific Northwest, a series of
lower-amplitude shortwave impulses should progress eastward through
early morning Monday. A plume of steepening mid-level lapse rates
is forecast to overspread the Pacific Northwest coast tonight. As a
result, low-topped convection moving ashore may intermittently be
capable of lightning flashes on an isolated basis near the coast.
Elsewhere, quiescent conditions for thunderstorms will prevail
across the remainder of the CONUS.
