This Hazardous Weather Outlook is for Western and Central Wyoming.

.DAY ONE...Today and Tonight.

Light snow showers linger east of the Continental Divide through the
morning, but little additional accumulation will occur. Daytime highs
will be well below normal in the single digits and teens. Breezy
north wind across mainly northern portions of the Bighorn Basin and
Johnson County will lead to sub-zero wind chill values at times
Saturday afternoon and evening.

.DAYS TWO THROUGH SEVEN...Sunday through Friday.

Sunday and Monday...Dangerously cold temperatures are forecast
starting Sunday morning. Brief clearing in cloud cover during the
early morning hours will lead to morning lows well below zero and
15 below to 20 below zero in some locations. Sunday highs remain in
the single digits and lower teens. Even colder temperatures are
forecast for Monday and Tuesday morning. Current forecasts are
showing morning lows on these days ranging from the 10 below to as
much as 25 below zero. Some locations could see even colder values if
the right conditions are met. After a very cold start, Monday high
temperatures struggle to get above zero across much of the state.

Tuesday...Gusty southwest wind allows for daytime highs to climb into
the teens and 20s. The wind could lead to areas of blowing snow
across central Wyoming, mainly Natrona County.

Wednesday through Friday...An active and unsettled weather pattern
returns for the second half of the week. Light snow would be favored
across the northwest and northern mountains in this pattern.
Temperatures remain below normal.

.SPOTTER INFORMATION STATEMENT...

Weather spotters are encouraged to report significant weather
conditions according to Standard Operating Procedures.
