A powerful winter storm is expected to move across Utah into
western Colorado Thursday night and Friday. This major winter
storm could bring significant snowfall to the mountain and valleys
throughout eastern Utah and western Colorado. The brunt of this
storm hits the region on Friday, but will last into Friday night.
The storm intensity will diminish on Saturday, but a chance of
snow showers will linger.

This is a dangerous and potentially life threatening winter storm
if caught unprepared. Factors that make this winter storm
particularly dangerous. Significant snow accumulations...moderate to heavy snowfall is expected on Friday as the winter storms hits the region. The potential exists for 1 to 2 feet of fine powdery snow across the high country. Snow is expected to be widespread and will impact travel with accumulating snow in the valleys...this includes the
interstate 70 corridor from eastern Utah to Vail pass.

Considerable blowing and drifting snow...the fine powdery snow
will be easy to blow and drift around. Combined with strong winds
on Thursday night and Friday morning...with some gusts to 60 mph
over the mountain passes of southwest Colorado and the Grand
Mesa...whiteout conditions will be possible. Gusty winds will
persist into Friday afternoon and night that will form deep snow
drifts.

Plunging temperatures...relatively mild conditions may exist
before the brunt of the winter storm hits. Temperatures will
plunge as the snow increases. Mountain readings in the 20s will
drop to the single digits by nightfall. Subzero temperatures will
be common by Saturday morning. Hypothermia and frostbite can occur quickly if caught outdoors cold and wet. Other risks include car
accidents and carbon monoxide poisoning.

If planning travel or outdoor activities across eastern Utah and
western Colorado later this week...be prepared for severe winter
weather conditions. Given the unique combination of plunging cold
temperatures...gusty winds and potentially heavy snowfall...expect
adverse winter weather conditions. remember...this next storm may
evolve into a dangerous winter storm.

This hazardous weather outlook is for eastern Utah and western
Colorado.

Day one...today and tonight

A chance of snow will persist over the northern Colorado mountains
through early this afternoon. Any accumulations will be very
light.

Days two through seven...Wednesday through Monday.

A powerful winter storm will be arriving on Thursday night and
continue into Friday. Snow will be widespread with significant
accumulations expected. at this time...the heaviest snow amounts is
expected over the northern and central mountains of western Colorado with upwards to 2 feet of snow above 9000 feet. The snow is expected to taper off on Saturday...but snow showers will persist in the high country.

Saturday through Monday...temperatures will become very cold once
again. Subzero temperatures at night will be common...with the
coldest of mountain valleys approaching 20 below zero and
possibly colder. High temperatures will be well below normal.
