Increasing clouds with areas of snow developing in the afternoon and evening

SITUATION
Skies were mostly clear again today. Temperatures rose into the 20s and 30s. Winds were from the west at 10 to 20 miles per hour.

Sunshine and warm temperatures during the day continue to form crusts. Clear skies and cold night time temperatures continue to promote surface hoar growth and faceting in the shallowest areas of the snowpack.



FORECAST FOR Friday, November 16, 2018
It will remain dry overnight; however cloud cover will increase steadily through the evening as the next weather system approaches. This system will move in from the north to the south. Snowfall is expected to develop Friday night. It will be a fast moving system that should bring several inches of snow to the mountains by noon on Saturday. Temperatures in the mountains will be in the teens and 20s on Friday and Saturday. Westerly winds will increase ahead of this approaching system.

The general avalanche will continue to be LOW above an elevation of 8,500 feet. Insufficient snow depths exist for avalanche hazards below that elevation.

TREND FOR Saturday, November 17, 2018 AND Sunday, November 18, 2018
Colder air will move into the region and dry conditions will prevail. The new snow may slightly elevate the avalanche hazard. The longer term prognosis points to a favorable pattern change around Thanksgiving.
