.DISCUSSION...

Breezy southwest winds that were over the fire this evening
will weaken between 2030-2200 to speeds near 5 mph.  Winds will
swing around to the south then northeast between 2300-0300 with
light speeds.  There are mid clouds streaming through the region
which at times, produced a few sprinkles upstream.  Any sprinkles
could lead to brief erratic winds from the southwest near 10-13 mph
for all elevations before 2200 then mainly on the ridgetops as inversions
strengthen.  Humidity recoveries will be poor overnight. General winds
will be out of the northeast Sunday morning then variable to terrain
driven in the afternoon.  Midlevel clouds will continue to move over
the fires Sunday into Sunday night with a 5-15% chance for sprinkles
and 5% chance for a dry thunderstorm.
