.DISCUSSION...A VERY DEEP MARINE LAYER HAS PUSHED INTO THE
CASCADES OVERNIGHT AND WILL PERSIST IN LARGE PART THROUGH FRIDAY.
UPPER AIR OBSERVATIONS FROM SALEM SUGGEST THE MARINE LAYER IS OVER
7000 FEET DEEP. THIS IS ALLOWING THE MARINE LAYER TO SPILL OVER
THE CASCADE CREST...WHICH WILL LIKELY KEEP IT RATHER WINDY NEAR
THE FIRE THROUGH FRIDAY. HOWEVER HUMIDITY WILL BE HIGH AND
TEMPERATURES COOL. ALSO SOME MOISTURE AND INSTABILITY ALOFT
CONTINUES TO CAUSE SCATTERED THUNDERSTORMS TO DEVELOP ALONG AND
JUST EAST OF THE CREST TODAY...BUT MOST OF THE LIGHTNING WILL BE
EAST OF THE FIRE.
