This Hazardous Weather Outlook is for the western two thirds of
Utah and southwest Wyoming.

.DAY ONE...Today and Tonight

Increasing south winds ahead of a cold front could become locally
strong across portions of west-central through southwest Utah

A strong cold front will slowly cross northern and western Utah
through tonight. Northern and western Utah valleys will see
measurable snow from this event which will impact travel this
evening and overnight. Significant accumulations will be possible
in the northern mountains and southwest Wyoming as well.

.DAYS TWO THROUGH SEVEN...Saturday through Thursday

The cold front is expected to stall across central Utah for a
time on Saturday, so central and southwest Utah valleys will end
up with the greatest valley snow totals. Most mountain sites will
likely see greater than a foot of new snow with the storm.
Locally heavy snow showers will continue through Saturday night
with accumulations also possible across the higher valleys of
eastern Utah.

Persons planning travel through Sunday should be prepared for
winter driving conditions in snow, and allow for plenty of extra
time to reach their destinations. Those traveling should also
consider the possibilities of closed roadways, and be prepared
with winter survival kits.

There is also a potential for some additional light snow across
the northern outlook area Monday.


Weather spotters are encouraged to report significant weather
conditions according to standard operating procedures.
