.DISCUSSION...Sunny skies with minimal fire weather
concerns as conditions will remain mild, and similar to Thursday.
Ample mixing today with periods of north-northeasterly winds -
especially in the afternoon as a weak thermal trough shifts
inland. On Saturday, a cold front will slowly move into the area
bringing with it breezy westerly to northwesterly winds and
increasing chances for precipitation. Orographic lift over the
burn area may increase chances for rainfall, but most looks to
fall well to the north. Winds will be higher on the north side of
the burn area within the valley, but winds will experience little
change through the day.
