.DISCUSSION...

Snow will likely impact the burn site today into tonight, with 3
to 6 inches forecast. The chance of seeing 8 or more inches has
decreased to 15 percent. Otherwise, gusty winds will continue to
impact the burn site today with gusts up to 30 mph this morning
before decreasing this afternoon and evening. Ridgetop winds look
to remain breezy tonight, so surface winds at the burn site will
likely remain out of the northwest, but periods of downslope winds
could develop (overall low chance). Wednesday will be a dry day.
