.DISCUSSION...

Winds from the west-southwest at 10 to 15 mph will shift to the
northwest as a cold front drops into the area during the early
afternoon. At this point, it seems that cold frontal passage at
the burn site will be sometime during the 1 PM to 3 PM time frame.
Winds will shift to the northwest then north at 15 mph.
Temperatures will top out in the next few hours then begin to
drop as the cold front moves through, with relative humidity
values bottoming out in the early afternoon then slowly rising as
temperatures come down. Mixing heights will also reach their peak
in the next few hours at near 7000 ft then start to come down
later this afternoon. Tonight, winds will shift to a more
northeasterly direction and there will be a chance for some
precipitation behind the cold front.
