FAST WESTERLY FLOW REMAINS OVER THE PACIFIC NORTHWEST COAST TODAY. 
WATER VAPOR IMAGERY SHOWS SERIES OF SHORTWAVE TROUGHS OFF THE
NORTHERN CA/ORE COAST THAT WILL AFFECT THE COASTAL AREAS THROUGH THE
FORECAST PERIOD.  FORECAST SOUNDINGS SHOW VERY MINIMAL INSTABILITY. 
THIS SUGGESTS THAT LIGHTNING ACTIVITY WILL BE VERY LIMITED IN
AREA/DURATION. HOWEVER...STRONG WIND FIELDS AND VERTICAL SHEAR MAY
RESULT IN LOCALLY DAMAGING WINDS IN STRONGEST CELLS AS THEY MOVE
ASHORE.

ELSEWHERE...NO THUNDERSTORMS ARE FORECAST ACROSS THE NATION TODAY.
