TUESDAY WILL SHIFT N INTO WA WITH WARM FRONT OVERRUNNING. THE UPPER
RIDGE HOLDS COLD FRONT AT BAY UNTIL AFTER TUE NIGHT. LIKENS

PUSH ENERGY NORTH OF FORECAST AREA MID WEEK. IT MANAGES TO DELAY THE

TOWARD THE END OF THE WEEK AND HAVE LITTLE CONFIDENCE IN THEM. AT
THIS TIME WILL GO WITH CLIMATOLOGY UNTIL THERE IS SOME CONSISTENCY
BETWEEN THE MODELS..

BRING VERY BRIEF MVFR CIGS. CONDITIONS REMAIN VFR THIS
AFTERNOON...THOUGH WILL SEE INCREASING MVFR ALONG THE COAST AS WARM
