638 PM PDT WED AUG 8 2012

FORECAST IS BASED ON REQUEST TIME OF 1734 PDT ON AUGUST 08.
IF CONDITIONS BECOME UNREPRESENTATIVE...CONTACT THE NATIONAL WEATHER
SERVICE.

.DISCUSSION...MAIN CONCERNS WILL BE HOW MUCH OF A HUMIDITY
RECOVERY OCCURS. ANOTHER ONSHORE PUSH OF MARINE AIR IS EXPECTED
TONIGHT INTO THURSDAY MORNING...BUT SHOULD BE SHALLOWER THAN THAT
SEEN TODAY. BECAUSE OF THIS...HUMIDITY RECOVERY SHOULD STILL BE
MODERATE...THOUGH LIKELY NOT AS MUCH OF A RECOVERY AS SEEN THIS
MORNING. THE INCIDENT AT 3000 FT MAY ACTUALLY BE ABOVE THE
SHALLOWER MARINE LAYER...SO CLOUDS THAT DO COME IN MAY NOT
COMPLETELY FILL IN. IF CLOUDS DO COME IN...EXPECT LOW LEVEL
INVERSION TO BEGIN BREAKING AROUND 0900-1000 WITH RAPID CLEARING
AGAIN. BECAUSE OF THE SHALLOWER MARINE LAYER AND WARMER AIR MASS
BUILDING IN...EXPECT WARMER AND DRIER CONDITIONS THURSDAY.
OBSERVATIONS FROM THIS AFTERNOON INDICATED UPSLOPE AND UPVALLEY
FLOW DOMINATED. EXPECT THAT POTENTIAL DOES EXIST THURSDAY
AFTERNOON...BUT THE PREVAILING WIND FLOW FROM THE NW MAY BE A BIT
STRONGER TO COUNTER THE UPSLOPE AND UPVALLEY WINDS.

THE MODERATE HAINES VALUES ARE DUE TO THE VERY DRY AIR ALOFT ABOVE THE
INVERSION...THOUGH INSTABILITY WILL AGAIN REMAIN EAST OF THE
CASCADE CREST.
