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

.DAY ONE...Today and Tonight

Strong winds and mountain snowfall will be the significant weather
features of the day. Snow will be heavy at times in the mountains
this afternoon, and then gradually decrease this evening. Travel
will be hazardous due to snow covered roads and poor visibility
in blowing snow and heavy snow showers. Total accumulations of 3
to 6 inches can be expected, with up to 8 inches under the heavier
snow bands.

Across the Front Range Foothills, I-25 Corridor, and adjacent
plains, it will become very windy. Peak gusts will reach 50 to 60
mph in most locations, with gusts in excess of 75 mph possible
across wind prone areas in and near the foothills. Travelers of
high profile vehicles should consider avoiding travel until winds
subside late tonight or Saturday. Areas of blowing dust may also
reduce visibility, so if traveling, be prepared to slow down when
encountering areas of blowing dust.

.DAYS TWO THROUGH SEVEN...Saturday through Thursday

Dry conditions and decreasing winds can be expected during the
morning hours Saturday with areas of blowing snow persisting
through the day over higher mountain passes and exposed areas. Dry
conditions and mild temperatures are expected for Sunday through
Wednesday ahead of the potential for colder and wintry weather
for the high country and lower elevations for late Wednesday into
Thursday.

.SPOTTER INFORMATION STATEMENT...

Spotter activation will not be needed today or tonight.
