COMMUNITY AND OTHER PARTNERS.

EMAIL TOPIC...WINTER WEATHER SYSTEM THIS WEEKEND

...REASONING IN EMAIL...

Overview: A storm system currently in the North Pacific will track
into the Western US early this weekend then move north through the
Northern Rockies and Montana. Rain and mountain snow is likely to
develop and spread northeast across the region Saturday night and
Sunday with snow levels initially around 6000 feet, lowering to the
plains and valley floors Sunday.

Impacts: Wet snow is expected over the mountains Saturday night and
Sunday with 3 to 8 inches of accumulation possible. Roadways over
mountains passes could become slushy and/or snow-covered and icy by
Sunday morning along with low visibilities. Snow accumulation is
also possible at lower elevations Sunday as cooler air moves into
the region, however temperatures at lower elevations will be near or
just above freezing, limiting the likelihood of snow accumulation on
roadways there.

Confidence: There is still some uncertainty in the track and
strength of this weather system, leading to lower confidence in the
specific location of highest precipitation amounts and snow
accumulations. Cold air associated with this system is also only
marginally supportive of snow at lower elevations where confidence
in snow amounts are lowest. However, a change from dry and mild to
much cooler and wetter conditions is likely this weekend with
specific details likely to become clearer by the end of this week.
