.DISCUSSION...Smoke dispersal the next few afternoons will be very
temperature dependent so any observations will be helpful. For now
went with an optimistic forecast for good dispersal the next few
afternoons even with inversions strengthening aloft. Winds will
be mainly out of the West/Northwest in the afternoons and slightly
stronger tomorrow. Winds aloft are strong enough that mixing should
tap into them and help overall dispersal.
