High Wind & Winter Storm Warning, Expanded Winter Storm Watch December 30, 2021 was created by MountainTownAlerts
Chief Meteorologist Steve Hamilton My Mountain Town Weather: UPDATE
High Wind Warning is in effect until 5:00 p.m. today (ugly green area on map).
Wind gusting at 25 to 40 mph, with occasional gusts to 80 mph in the wind-prone areas.
This includes Jefferson and West Douglas Counties Above 6000 Feet, Gilpin, Clear Creek, and Northeast Park Counties Below 9000 Feet, Larimer County Below 6000 feet, Northwest Weld County and Boulder, and Jefferson Counties Below 6000 Feet as well as western Broomfield County.
Damage to power lines, leading to power outages possible.
Difficult travel especially for high-profile vehicles.
Winter Storm Watch...
The National Weather Service in Boulder has issued a Winter Storm Watch (green highlight on map), in effect from late Thursday night through Saturday morning.
Snow is possible, with some areas of heavy snowfall. Accumulation of 5 to 12 inches possible.
This includes the Northern Front Range Foothills, The Southern Front Range Foothills, Fort Collins, and Boulder and the western suburbs of Denver.
Local forecast:
Cold Arctic air will race down the eastern side of the Rockies and arrive here Friday night, and New Year's Day. And, a Pacific storm system will move in by Thursday night, bringing us a decent chance of accumulating snow for the Front Range. The best window for accumulating snow will be Friday and Friday night, generally between 5 to 12". Higher amounts for Fairplay, Alma, Jefferson and Como, where a Winter Storm Warning is in effect until 5:00 a.m. Saturday. More good news for the mountains, where we could see up to 20" of fresh snow. Road conditions are likely to be icy and snow packed New Years Eve and early New Year's Day. Also, gusty wind will cause blowing snow and poor visibility, and the temperatures will get very cold. If you're going to be out and about Friday night, be prepared for hazardous winter driving conditions.
