.DISCUSSION...
APPROACHING TROUGH WILL GENERATE SOUTHWESTERLY RIDGETOP WINDS OVER
THE FIRE AND THIS WILL ENHANCE WINDS IN PROPERLY ALIGNED CANYONS.
LOWER ELEVATIONS MAY EXPERIENCE A MORE WESTERLY WIND IN THROUGH
DEER CREEK CANYON THIS AFTERNOON WHILE THE UPPER ELEVATIONS MAY
HAVE SOUTHERLY WINDS FUNNELED INTO N-S SECONDARY CANYON. DRYING
NORTHEAST WINDS HAVE CREATED POOR RH RECOVERY. BUT WITH TROUGH
APPROACHING, MIN RH THIS AFTERNOON WILL NOT BE AS LOW AS MONDAY
AND RECOVERY WILL BE MUCH BETTER TONIGHT INTO WEDNESDAY.
