GEN TSTMS ARE FCST TO THE RIGHT OF A LINE FROM 25 N BLI SEA EUG 35
ENE 4BK 30 WSW CEC.

...NO SVR TSTM AREAS FORECAST...

...PACIFIC NORTHWEST COAST...
CONVECTIVE BAND FOCUSED ON LEADING EDGE OF STRONGER MID-LEVEL
COOLING ASSOCIATED WITH APPROACHING SHORT WAVE TROUGH IS CURRENTLY
PROGRESSING INLAND.  TO THIS POINT...THUNDERSTORM ACTIVITY HAS
GENERALLY BEEN CONFINED TO AREAS OFF THE OREGON COAST...WHERE
LOW-LEVEL WARM ADVECTION AHEAD OF FRONTAL ZONE WAS MAXIMIZED THIS
AFTERNOON.  HOWEVER...LOW-LEVEL WARMING/MOISTENING INLAND OF PACIFIC
COASTAL AREAS LATER THIS EVENING...IN RESPONSE TO INCREASING ONSHORE
COMPONENT TO FLOW AS UPPER TROUGH PROGRESSES INLAND...STILL APPEARS
LIKELY TO CONTRIBUTE TO WEAK DESTABILIZATION.  THIS MAY BECOME
SUFFICIENT FOR SCATTERED WEAK THUNDERSTORM ACTIVITY...POSSIBLY AS
EARLY AS THE 02-03Z TIME FRAME...WHICH COULD PERSIST THROUGH THE
NIGHT.

...EAST OF THE ROCKIES...
THOUGH CENTER OF BROAD SURFACE RIDGE WILL CONTINUE TO RETREAT INTO
THE EASTERN STATES OVERNIGHT...RIDGING IS PROGGED TO PERSIST ACROSS
WESTERN GULF COASTAL AREAS.  THIS WILL IMPEDE RETURN FLOW OF
MOISTURE FROM SLOWLY MODIFYING BOUNDARY LAYER OVER THE WESTERN GULF
OF MEXICO...AND SHOULD PRECLUDE RISK FOR THUNDERSTORMS IN
STRENGTHENING LOW-LEVEL WARM ADVECTION REGIME ACROSS THE CENTRAL/
SOUTHERN PLAINS.
