...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Severe thunderstorms are not expected through tonight.

...Discussion...
A progressive low-amplitude flow regime will persist over the CONUS,
with split flow along the West Coast including a southern-stream
upper low off the coast of California. Semi-steep mid-level lapse
rates exist in proximity to the upper low near the north-central
California coast, with related isolated thunderstorm potential
mainly early today. However, this thermodynamically conducive
environment will trend less favorable over time. Additionally, a few
lightning flashes may occur today across the central Rockies in
association with an eastward-moving shortwave trough.
