...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Severe thunderstorms will not occur over the contiguous United
States tonight.

...Synopsis...
Water-vapor imagery this evening shows a mid-level low slowly moving
eastward towards northern Baja California.  This feature is forecast
to reach the mouth of the CO River by early Thursday morning. 
Increased large-scale ascent associated with the disturbance and
gradual mid-level moistening will lead to widely scattered showers
developing tonight over the Sonoran Desert.  Relatively cold
temperatures aloft (reference -20 dec C at 500 mb sampled by the 00z
San Diego, CA raob) may support a few weak thunderstorms with this
activity.
