General Discussion: The weekend is shaping up to be very nice for hanging out in the mountains.

Long-term: The next significant weather event is expected to hit the mountains early Monday morning. This will bring rising freezing levels, heavy precipitation and winds to the PNW for the Thanksgiving week.

A cold front is expected on Tuesday with another round of heavy snow. Early precipitation water equivalent storm totals are +3” by Thanksgiving day.
