...The West...
Day 3...

A pair of upper level troughs; one in the central Rockies and
another approaching the Pacific Northwest, will produce some high
elevation mountain snow in parts of these regions mountain ranges
Thursday night. The most notable ranges expecting moderate-to-
heavy snowfall include the Olympics, Cascade Range, Blue Mountains,
the Absaroka, Tetons, Wind River, and Colorado Rockies. Elevations
most likely to see the heaviest totals would be >6,000ft in the
Olympics and Cascade Range, >7,000ft in the Blue Mountains, and
>9,000ft in the Absaroka, Tetons, Wind River, and Colorado Rockies.
WPC PWPF generally shows low chances (10-30%) for >6" of snowfall
at or above those listed elevations. Look for additional mountain
snow to take shape during the day on Friday. Little in the way of
snowfall in the valleys of the Intermountain West are expected.


The probability of significant icing is less than 10 percent.
