Valid 021200Z - 031200Z

....NO THUNDERSTORM AREAS FORECAST...

....SUMMARY...
The risk of thunderstorms appears negligible across the U.S.,
Thursday through Thursday night.

....Discussion...
An initially notable short wave trough, approaching the British
Columbia and Pacific Northwest coast by 12Z Thursday, appears likely
to continue inland during this period.  Considerable weakening of
this perturbation and its associated occluding surface cyclone/
trailing front are forecast, as it progresses through lingering
larger-scale mid-level ridging.  Models indicate little appreciable
destabilization, minimizing the risk for thunderstorm activity.

East of the Rockies, although temperatures may begin to moderate,
cold surface ridging is forecast to be maintained across the
northwestern Gulf coast, lower Mississippi Valley, and much of the
Southeast into the northwestern Atlantic.
