A SHORTWAVE TROUGH AND ASSOCIATED BAROCLINIC LEAF IS CURRENTLY
EVIDENT ON WATER VAPOR IMAGERY ALONG THE WEST COAST. AS THIS FEATURE
MOVES INLAND THIS AFTERNOON...FOCUSED ASCENT WITH THE TROUGH AND
WEAK INSTABILITY SHOULD BE ENOUGH TO CONTINUE THE POSSIBILITY FOR
ISOLATED CONVECTION. THE GREATEST CHANCE FOR ISOLATED THUNDERSTORM
ACTIVITY SHOULD BE ALONG THE ORE AND WA COAST AS THE LEFT FRONT
QUADRANT OF AN APPROACHING 80 KT MID-LEVEL JET STREAK PASSES
OVERHEAD LATE THIS AFTERNOON. THE SHORTWAVE TROUGH AND ASSOCIATED
MID-LEVEL JET WILL DRIFT EWD INTO THE PACIFIC NW OVERNIGHT ALLOWING
THE THUNDERSTORM POTENTIAL ALONG THE COAST TO GRADUALLY DECREASE.

ELSEWHERE...THUNDERSTORM ACTIVITY IS NOT EXPECTED ACROSS THE CONUS.
