DENVER -- Dropping temperatures will turn rain into all snow overnight into Friday morning. The snow will be accompanied by a gusty north wind.
Temperatures are expected to dip below freezing early Friday that will cause roads to turn slick.
Additional accumulation is also expected overnight, with a couple of inches in Denver. There will be the potential for another 2-5 inches north and south of the city. And the foothills could easily add another foot.
Widespread rain fell across Denver throughout the day, with temperatures only climbing into the low 40s and some snow mixing in during the day west of Interstate 25 and south of the city.
Once the sun set Thursday night, the best chance for all snow kicked in for Denver along with the best chance of accumulation.
Downtown Denver will see 3 inches of accumulation from the storm as the rain-snow line wobbled throughout the day. Heavier amounts of snow fell farther west and north of the city.
The heaviest snow accumulations were above 6,000 feet, including parts of the foothills, and Continental and Palmer divides.
Driving conditions quickly deteriorated on Interstate 70 west of Denver above 6,500 feet, where heavy snow fell in the foothills and mountains Thursday.
The biggest bulk fell in the northern mountains at Estes Park (36 inches), Red Feather Lakes (40 inches) and Longs Peak (42 inches).
Southern Wyoming might get up to 1-2 feet of snow, which will make travel on Interstate 80 very difficult.
The central mountains will not be exempt, with 14 inches expected at Loveland Ski Area and 16 inches in Winter Park.
With trees leafed out, the chances for snapping branches are high.
There were reports of large tree branches broken up and down the Front Range. The heavy, wet snow also weighed down on power lines, likely leading to power outages.
Xcel Energy reported several outages in different locations. The Boulder County Sheriff's Office said about 5,500 customers in its jurisdiction were without power Thursday afternoon.
A winter storm warning was in effect until Friday afternoon for the southern foothills. A winter storm watch went into effect for the Denver metro area from Thursday afternoon to Friday morning.
Temperatures will plunge to near or just below freezing on Friday morning, making potted and sensitive planted outdoor plants vulnerable.
Precipitation will wind down Friday, with Saturday and Sunday looking mostly sunny and dry. Highs will be in the upper 50s on Saturday and the mid-60s on Sunday.
