SPOT FORECAST FOR LRB ORCHARD...BIA
NATIONAL WEATHER SERVICE GAYLORD MI
1034 AM EDT THU APR 23 2009

FORECAST IS BASED ON IGNITION TIME OF 1200 EDT ON APRIL 23.
IF CONDITIONS BECOME UNREPRESENTATIVE...CONTACT THE NATIONAL WEATHER
SERVICE.

.DISCUSSION...MAIN CONCERN FOR THE BURN WILL BE THE WINDS AND
THEIR RELATION TO THE RELATIVE HUMIDITY. EXPECTATIONS ARE FOR THE
WINDS AT ABOUT 1000 FEET TO MIX DOWN DURING THE AFTERNOON AND KEEP
THE LAKE BREEZE FROM FORMING AND MOVING INTO THE BURN AREA. THIS
WILL KEEP THE SURFACE WINDS OUT OF THE SOUTH AND THE RELATIVE
HUMIDITY BETWEEN 20 AND 25 PERCENT. IF THE WINDS TURN TO THE
SOUTHWEST...THEN THE RELATIVE HUMIDITY WILL CLIMB TO AROUND
40 PERCENT.
