SPOT FORECAST FOR SOUTH POINT...USFS GIFFORD PINCHOT
NATIONAL WEATHER SERVICE SEATTLE WA
345 PM PDT TUE OCT 2 2012

FORECAST IS BASED ON REQUEST TIME OF 1517 PDT ON OCTOBER 02.
IF CONDITIONS BECOME UNREPRESENTATIVE...CONTACT THE NATIONAL WEATHER
SERVICE IN SEATTLE.

.DISCUSSION...THE STRONG UPPER LEVEL RIDGE BUILDING OFFSHORE WILL
DOMINATE THE WEATHER PATTERN THROUGH NEXT WEEKEND...PRODUCING A
PROLONGED PERIOD OF VERY DRY WEATHER AND AN EAST WIND PATTERN. THE
FIRE SITE APPEARS TO BE A LITTLE SHELTERED FROM DIRECT EAST WINDS
SO THE WIND DIRECTION WAS SHIFTED TO MORE NORTH TO NORTHEAST TO
FOLLOW THE GENERAL CONFIGURATION OF THE COWLITZ RIVER VALLEY.

SURFACE HIGH PRESSURE BUILDING OVER SOUTHERN BRITISH COLUMBIA THIS
AFTERNOON IS MOVING A VERY DRY AIR MASS SOUTHWARD OVER EASTERN
WASHINGTON AND THE CASCADES. AS THE HIGH SLIDES SOUTHEAST OVER THE
ROCKIES TONIGHT...EASTERLY WINDS WILL BEGIN DEVELOPING ACROSS
WESTERN WASHINGTON. THE COMBINATION OF THE ALREADY DRY AIR AND THE
EASTERLY FLOW WILL CAUSE RELATIVE HUMIDITIES TO DROP INTO THE 20 TO
35 PERCENT RANGE THE NEXT FEW DAYS WITH POOR TO MARGINAL HUMIDITY
RECOVERY AT NIGHT.

THE STRONG RIDGE WILL REMAIN ANCHORED OFFSHORE INTO EARLY NEXT WEEK
PUTTING WESTERN WASHINGTON IN A PROLONGED PERIOD OF DRY EASTERLY
WINDS. THE WINDS WILL REMAIN PREDOMINANTLY LIGHT...BUT THERE COULD
BE SHORT PERIODS OF LOCALIZED MODERATE EAST WINDS THROUGH FRIDAY.
