...NO THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Thunderstorms will not occur over the contiguous United States
through tonight.

...Synopsis...
A mid-level ridge building across the central and western US will
shunt strong westerlies northward toward the Canadian border as an
amplified trough departs the East Coast. At the surface, high
pressure will dominate much of the Lower 48. Dry and stable
conditions across much of the CONUS will prevent thunderstorm
development.
