    Snow will continue to fall on a large part of Colorado and the central Rockies and result in travel delays into Monday evening.

    Those with travel plans along interstates 25, 70 and 80 in Colorado and Wyoming should anticipate slower commute times, drastically changing weather conditions and snow-covered roads to start out the week.

    A storm is pushing through the Rockies along the leading edge of cold Canadian air pressing southward through the Rockies and northern Plains, according to AccuWeather Senior Meteorologist Jack Boston.

    The combination of the cold and the storm will lead to accumulating snowfall across the region.

    Several inches of snow first accumulated across the northern Rockies on Sunday night, leading to times of slick travel along portions of Interstate 90 in Montana.

    The Colorado Department of Transportation reported that snow tires and chains are now required for all vehicles using the Loveland Pass as of 10:00 p.m. local time on Sunday.

    The snow and cold then swept southeastward through Wyoming and Colorado - Denver received their first accumulating snow late Sunday night.

    A general 3 to 6 inches of snow is expected along the I-25 corridor from Denver on north into Wyoming. The foothills of the Rockies and Palmer Divide will see amounts on the higher end of that range. Snow totals across the higher terrain will reach a foot or more.

    Temperatures will drastically plunge from the 60s and 70s F on Sunday to the 30s on Monday.

    Roadways will turn from wet to slushy and snow-covered in a short amount of time. Motorists will need to slow down to avoid spin outs and multiple car pileups.

    Gusty winds may cause whiteout conditions at times, causing further hazards to travelers.

    The snow could weigh heavily enough on trees that have not shed their leaves to break branches. Trees that fall on power lines could trigger sporadic power outages.

    Even though the storm will depart Monday night, some hazardous conditions will linger.

    A fresh snow cover, clearing skies and calming winds on Monday night will lead to a hard freeze. Temperatures will drop into the 10s and 20s.

    Quieter and milder conditions are in store across the region for the remainder of the second week of October.

    Motorists and pedestrians should watch for ice on roadways and sidewalks as untreated surfaces made wet by natural melting during the day freeze during the overnight and early morning hours.
