.DISCUSSION...
Cooler today but warmer Wednesday. Lower humidity today and Wednesday.
Typical afternoon breezes each day with no high winds expected. Higher
mixing heights in the afternoons will loft smoke into the upper
atmosphere with few smoke impacts at the surface downwind
(southeast-wards) of the burn, but steeper valley inversions in the
morning and late evening will trap any smoke in the local burn area
produced during these times.
