SPOT FORECAST FOR BULLHOG CHIP RX
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
449 AM MDT THU OCT 8 2009

.DISCUSSION...AN UPPER LEVEL TROUGH IS BEING CARVED OUT ACROSS THE
NORTHERN ROCKIES TODAY. THE ASSOCIATED WEAK COLD FRONT WILL MOVE
ACROSS THE PRESCRIBED BURN AREA ABOUT 0800 TO 1000 THIS MORNING.
THIS FRONT IS RATHER DIFFUSED BUT WINDS ALOFT BECOME SLIGHTLY
STRONGER THIS AFTERNOON SO THE SURFACE WINDS SHOULD PICK UP AS
WELL. MOISTURE IS LIMITED WITH THIS FRONT AND SHOULD STAY MAINLY
ALONG THE WASATCH FRONT AND POINTS FARTHER NORTH. HOWEVER...THERE
IS A 20 PERCENT CHANCE THAT A BROKEN DECK OF CLOUDS AT BETWEEN
2000 AND 4000 FEET COULD FORM BETWEEN 16Z AND 22Z. WINDS COULD
GUST AS HIGH AS 10-15 MPH BETWEEN 17Z AND 22Z BEFORE RELAXING. THE
WINDS ALOFT WILL BE NORTHWEST TO NORTH AT 10-15 MPH TODAY
RESULTING IN GOOD HORIZONTAL TRANSPORT. A SUBSIDENCE INVERSION AT
13000 FT MSL WILL LIMIT THE VERTICAL MIXING BUT STILL SUFFICIENT
TO ACHIEVE A CLEARING INDEX ABOVE 700.

NOTE: FORECAST IS FOR THE LAT/LON GIVEN ON THE SPOT WHICH IS OUT
IN THE RUSH VALLEY. THE LAT LON FOR THE BULLHOG CHIP RX IS 5
MILES EAST OF THE SCLFO MICRO.
