FORECAST IS BASED ON REQUEST TIME OF 1527 PDT ON OCTOBER 08.
IF CONDITIONS BECOME UNREPRESENTATIVE...CONTACT THE NATIONAL WEATHER
SERVICE IN SEATTLE.

.DISCUSSION...HIGH PRESSURE WILL CONTINUE TO BE THE PREVALENT
WEATHER FEATURE OVER THE FIRE SITE THROUGH WEDNESDAY. THIS WILL
ALLOW FOR LIGHTER...MORE TERRAIN DRIVEN WINDS...AS WELL AS THE
SLOW DEVELOPMENT OF A MORE ONSHORE FLOW. WHILE THIS WESTERLY SHIFT
IN FLOW WILL ALLOW FOR SOME INCREASE IN RELATIVE HUMIDITY VALUES
IN AREAS...IT WILL BE OFFSET BY THE CONTINUED DRY CONDITIONS AND
POSSIBILITY OF LOW-LEVEL SUBSIDENCE INVERSIONS SETTING UP DUE TO
THE LENGTH OF TIME THE HIGH HAS BEEN OVERHEAD. THESE INVERSIONS
MAY IMPACT OVERNIGHT HUMIDITY RECOVERIES. HIGH PRESSURE WILL
EVENTUALLY BREAK DOWN THURSDAY...RESULTING IN AN INCREASE IN
CLOUDS AND A CHANCE FOR PRECIPITATION FOR THE WEEKEND.
