.DISCUSSION...Cooler and drier conditions will exist over the burn area
through the day on Wednesday under mostly clear skies. A few
afternoon cloud build-ups are expected over the high terrain
features. Winds are expected to be generally light and terrain
driven, with southerly aspects and higher exposure areas expected
to see wind gusts of up to 15 mph out of the south.

Moisture increases over the area by Friday, bringing at least a
slight chance for showers and an isolated thunderstorm during the
afternoon hours. Passing showers are expected to bring little, if
any, precipitation over the burn area. Winds maintain a diurnally
driven flow pattern through the day on Friday, with a chance for
gusty and erratic outflow winds with passing showers.

Cooler temperatures and a fair shot of precipitation is expected
over the weekend, however, chances for wetting rains remain low.
A trend featuring warming temperatures and drying conditions is
expected to spread over the area into early next week. Good to
excellent clearing is anticipated through the next 7 days.
