FORECAST IS BASED ON REQUEST TIME OF 0926 PDT ON JULY 31.
IF CONDITIONS BECOME UNREPRESENTATIVE...CONTACT THE NATIONAL WEATHER
SERVICE IN SEATTLE.

.DISCUSSION...THE GRAND PARK FIRE WILL STAY WELL ABOVE THE
INFLUENCE OF THE MARINE PUSH WHICH ARRIVED IN THE LOWLANDS LAST
NIGHT. THEREFORE...THE FIRE WILL REMAIN IN A WARM...DRY AND
UNSTABLE ENVIRONMENT THROUGH SATURDAY WITH POOR HUMIDITY RECOVERY
TONIGHT. FROM THE FIRE...CUMULUS BUILDUPS MIGHT BE SEEN THIS
AFTERNOON TO THE EAST BUT SHOULD NOT BUILD SIGNIFICANTLY OVER THE
FIRE ITSELF. WIND DIRECTIONS WILL BE HARD TO PIN DOWN BUT WILL
CERTAINLY BE INFLUENCED BY DIURNAL TERRAIN EFFECTS. HOWEVER...WIND
SPEEDS SHOULD NOT BE REMARKABLE.
