This hazardous weather outlook is for northeast and north central
Colorado.
.DAY ONE...Today and Tonight
Strong winds will develop in/near the Front Range Mountains and
Foothills late tonight with peak gusts of 55-65 mph, and
localized gusts up to 75 mph in/immediately adjacent to the
foothills of Boulder County.
Snow will move into the mountains this evening, and then shift
mainly to areas north of the I-70 Mountain Corridor and Summit
County late tonight. Travel will become slick and hazardous in
the mountains later this evening as temperatures fall and roads
become snow covered. Only isolated to scattered light showers will
occur on the plains, most of these closer to the Wyoming border.
.DAYS TWO THROUGH SEVEN...Monday through Saturday
Snow and areas of blowing snow will continue Monday, mainly in
the mountains north of the I-70 Corridor and Summit County. Storm
total accumulations by the time snow winds down late Monday will
be 4 to 10 inches in the mountains from Rabbit Ears Pass
northward. The northern Front Range mountains should see anywhere
from 2-6 inches, with lighter amounts of 1-3 inches in the
mountains of Summit County (most of that falling mid to late
this evening). The strong and gusty winds along the Front Range
and northern border area will gradually decrease Monday afternoon
and evening.
Temperatures will turn cooler early next week and hold near or
below normal through the remainder of this outlook. There will be
another chance of rain and snow Thursday into Friday, but
considerable uncertainty exists regarding the track and intensity
of this potential storm system.

A brief round of heavy wind driven snow will impact the
Continental Divide mountains late this afternoon through tonight.
