A combination of an upper level storm system and the subtropical jet stream moving straight over the top of Colorado is resulting in a winter storm -- with several different components.
The main impact is on the mountain peaks and passes above 9,000 feet. Snow there will continue to be heavy, and steady until just after midnight Saturday.
Most of the totals will end up in the 6 to 12 inch range, but favorable slopes could get more than 16 inches.
The mountain towns between 7,500 and 9,000 feet will continue to deal with warm temperatures and down-sloping winds, so they will not get big snow totals, mostly between 2 and 4 inches. Most of that accumulation will happen later Friday night after the passage of the main cold front. Some of the higher towns, like Leadville will get more snow, likely between 4 and 8 inches.
The metro areas along Interstate 25 will have to wait until the cold front arrives to get any noticeable precipitation. There have been a few spillovers from the mountains, but those showers have quickly dried up.
The cold front will move through the metro area Friday evening between 6 p.m. and 11 p.m.
Expect a mix of precipitation at that time, although computer models are not showing much moisture at all. The Elbert County section of the Palmer Divide could get a little bit of snow accumulation, maybe an inch or so.
Snow accumulation is not likely in Denver.
Winds will continue to be a nuisance for the entire region -- not strong enough for an advisory to be issued though. They'll mainly be between 15 and 30 mph.
The cold air will press into the air overnight into Saturday morning. Metro areas and the eastern plains will wake up to temperatures below freezing. The mountains wil experience temperatures in the 20's and 30's.
Saturday will be clear, and dry, with lots of sunshine, but with that cold air still moving down from the north, high temperatures will struggle to reach 50 degrees for most of us.
