.DISCUSSION...

HIGH PRESSURE WILL REMAIN THE DOMINANT WEATHER FEATURE PRESENT OVER
THE BURN AREA THROUGH SATURDAY NIGHT. DESPITE MOSTLY CLEAR SKIES AND
VERY WARM EARLY OCTOBER TEMPERATURES...THE PROGRESSIVELY LOWER SUN
ANGLE WILL PREVENT LOW ELEVATIONS FROM REACHING THEIR MAXIMUM MIXING
POTENTIAL DURING SATURDAY AFTERNOON. ALSO...LIGHT WINDS WILL BE
PRESENT AND LOW ELEVATION SMOKE MAY BECOME TRAPPED IN THE ADJACENT
VALLEY. MIXING WILL INCREASE DURING SUNDAY...AS A PACIFIC STORM
SYSTEM APPROACHES THE NORTHERN ROCKIES. RH RECOVERY WILL BE SOMEWHAT
POOR AT HIGH ELEVATIONS OVERNIGHT SATURDAY DUE TO INCREASING WINDS
AT THE RIDGETOPS. THE SURFACE COLD FRONT IS ANTICIPATED TO PASS THE
BURN SUNDAY EVENING...WITH WETTING RAIN POTENTIAL INCREASING
SIGNIFICANTLY AFTER MIDNIGHT.
