.DISCUSSION...
Warmer with lower humidity today and Tuesday. Average afternoon
breezes each day with no high winds expected for the next week.
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.
