Mount Rainier Recreational Forecast
National Weather Service Seattle WA
444 AM PST Mon Dec 18 2017

.SYNOPSIS...A cold front will turn up stationary near Mount
Rainier this afternoon. A strengthening low center will track
across Northwest Washington on Tuesday, with a sharp cold front
trailing the low and passing the mountain on Tuesday afternoon.
This will bring heavy mountain snow and windy weather on Tuesday.
A few lingering snow showers will continue Tuesday night and
Wednesday morning. A cold and dry air mass will end the showers on
Wednesday afternoon. Around Thursday night, a wave diving
southeast through B.C. will increase clouds with a low chance of
light snow. Cool and dry weather expected under high pressure
from later Friday through next weekend.

&&

.IMPACTS...Stormy weather will create difficult backcountry
skiing and mountaineering conditions across much of the alpine
terrain of Mt. Rainier, including the Muir snowfield. Blizzard-
like conditions with strong winds and near zero visibility are
likely. A high level of skill and experience in alpine terrain,
including use of GPS, is recommended for navigation and camping in
these conditions.
