...NO THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Thunderstorms are not expected across the continental United States
this evening and tonight.

...DISCUSSION...
An upper-level trough will move from the Eastern Seaboard into the
western Atlantic this evening as an upper-level ridge moves into the
High Plains. At the surface, a dry and cool airmass will be in place
from the Rockies eastward to the Eastern Seaboard. As a result,
instability will be minimized across much of the nation, and
thunderstorms are not expected this evening and tonight across the
continental United States.
