....NO THUNDERSTORM AREAS FORECAST...

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

....Discussion...
After emerging from a strong jet nosing across the southern
mid-latitude Pacific, a short wave trough, approaching the British
Columbia/Pacific Northwest coast by 12Z Thursday, is forecast to
continue inland through the period.  As it progresses through the
crest of lingering larger-scale mid-level ridging along the North
American Pacific coast, models indicate that an associated surface
cyclone and trailing front will continue to occlude and rapidly
weaken while advancing onshore.  Little appreciable destabilization
is forecast, with thermodynamic profiles largely remaining
unsupportive of convection capable of producing lightning.

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.
