SPOT FORECAST FOR TA-4 RUMBLE HILL OAK...FT LEWIS FORESTRY
NATIONAL WEATHER SERVICE SEATTLE WA
1000 AM PDT THU JUL 7 2011

FORECAST IS BASED ON IGNITION TIME OF 1300 PDT ON JULY 07.
IF CONDITIONS BECOME UNREPRESENTATIVE...CONTACT THE NATIONAL WEATHER
SERVICE IN SEATTLE.

.DISCUSSION...A MODERATELY STRONG UPPER TROUGH WILL MOVE INTO THE
AREA TODAY WITH STRONG ONSHORE FLOW. THE HEAVY CLOUD COVER WILL
SLOWLY LIFT AND BREAK UP SOME THIS AFTERNOON. THERE IS AREAS OF
DRIZZLE WELL TO THE NORTH OF THE BURN AREA AND I CONTINUE TO EXPECT
THIS TO REMAIN TO THE NORTH. HOWEVER THERE IS A SMALL THREAT OF A
PASSING LIGHT SHOWER DURING THE AFTERNOON...MAINLY AFTER 2 PM.

THERE WILL BE A STEADY BREEZE THROUGH THE DAY WITH THE STRENGTHENING
ONSHORE FLOW. THE NISQUALLY VALLEY WILL LIKELY INFLUENCE THE
WIND DIRECTION SIGNIFICANTLY THIS MORNING WITH A MORE SOUTHERLY BEND
TO THE WIND...BUT WITH THE BURN AREA ON THE BENCH I WOULD EXPECT THE
WIND TO BECOME MORE WESTERLY THIS AFTERNOON WITH MORE MIXING.

 MINUTE AVERAGES REFLECTING RAWS WINDS.
