DISCUSSION
GUSTY WEST TO NORTHWEST WIND PERSISTS FOR THE NEXT SEVERAL DAYS.
THE OVERALL WEATHER PATTERN FAVORS PREVAILING SPEEDS OF 20 TO 35 MPH
WITH OCCASIONAL HIGHER GUSTS. THE IMMEDIATE HIGHER TERRAIN TO THE
WEST OF THE BURN SITE ALONG WITH THE KITTY CREEK DRAINAGE
TOPOGRAPHY MAY CREATE DIFFERING WIND SPEEDS AND DIRECTIONS AT TIMES.
HOWEVER, THE PERSISTENT WIND WILL BE WESTERLY 20 TO 35 MPH.
ONGOING PRECIPITATION SLOWS LATE TODAY AND A BREAK IN THE
PRECIPITATION PREVAILS OVERNIGHT AS THE STORM TRACK SHIFTS NORTH
INTO MONTANA. THE ARRIVAL OF ANOTHER WEATHER SYSTEM IN NORTHWEST

THURSDAY AFTERNOON. TEMPERATURES REMAIN MILD FOR THIS TIME OF YEAR.
