.DISCUSSION...
Skies will continue to clear at the burn site over the next hour, with clear
skies thereafter. The temperature and humidity forecast remains a bit tricky
given this area is right on the cusp of the clearing, but temperatures are still
expected to warm with humidity dropping. Winds will remain quite light and
variable through the remainder of the afternoon. Smoke dispersal will be poor
given the light transport winds. Quiet weather is expected tonight.
