This hazardous weather outlook is for northeast and north central
Colorado.

.DAY ONE...Today and Tonight

The Park Range and the northern Front Range mountains will see
steady light to moderate snowfall throughout the day today and
tonight. Snowfall rates will be between 0.5 to 1 inch per hour for
much of the day with rates up to 2 inches per hour possible.
Total snowfall amounts through the day on Monday will be between 8
to 18 inches. Expect snow-covered roads and hazardous travel
conditions. Across the I-70 mountain corridor, flurries and light
snow showers are expected today with minimal impact to travel
beyond the snow that is already on the roads. Light snow, with
accumulations generally around an inch, will fall late this
afternoon and through the evening across the I-25 corridor and
eastern plains.

Very cold temperatures will persist today with highs in the single
digits across the plains. Lows tonight will drop below 0 F across
the I-25 corridor and plains with some spots reaching as cold as
-10 F. Wind chills may reach -20 F so a Wind Chill Advisory will
be in effect from 7pm tonight through 9am Monday.

.DAYS TWO THROUGH SEVEN...Monday through Saturday

An arctic airmass will continue east of the mountains with a
chance of light snow over the plains. Wind chill values will drop
near -25 Monday morning and will likely remain below zero during
the day Monday.

In the mountains, snow will continue over the mountains and will
be heavy at times over the northern areas. Accumulations over the
I-25 mountain corridor will be lighter.

Temperatures will begin to moderate by the middle of the week.

.SPOTTER INFORMATION STATEMENT...

Snowfall reports from spotters are appreciated.
