...Light to Moderate Snow and Occasional Strong Winds Moving Into
the Mountains Tonight and Continuing Through the Weekend...
.A prolonged flow of Pacific moisture is forecast to move into
the Rocky Mountains of Colorado from later tonight through the
weekend. The moist airmass is being driven by strong westerly
winds aloft which will create an efficient snowfall producing
storm system. Once snow begins falling in the northern and central
Colorado mountains this afternoon or tonight, it is expected to
continue falling through Sunday afternoon. Snowfall rates will
vary from less than inch an hour up to one or two inches per hour
at times. Along with the snowfall, periods of gusty winds may also
develop which will create blowing and drifting snow with poor
visibilities. The initial period of moderate snowfall is expected
tonight and Friday morning with a possible decrease Friday
afternoon and evening. A second wave of moisture is then expected
to arrive by Saturday which will keep the snow machine running
into Sunday. Snowfall accumulations by Friday afternoon could be
12 to 18 inches. Additional accumulations over the weekend could
amount to another foot, or more.
Travel through the mountains will be difficult from Friday through
Sunday, especially during periods of moderate to heavy snow and
strong winds. If you are planning to travel through the mountains
Friday through Sunday, check cotrip.org often for the latest road
conditions and be prepared for extremely difficult travel
conditions.

* ADDITIONAL DETAILS...A lull in the storm is possible Friday
afternoon or evening, but it may be short-lived or may be masked
by periods of gusty winds that produce blowing and drifting of
freshly falling snow. Travelers into the mountains should be
prepared for very difficult travel conditions.
If you must travel, keep an extra flashlight, food, and water in
your vehicle in case of an emergency.
