Ready for more snow and cold?
After two rounds of snowfall so far this month, another – and perhaps a second midweek – round of accumulating snow looks like it’s on the way this weekend for Denver and the Front Range.
A sharp cold front will dive south out of Canada this weekend, bringing yet another reinforcing shot of winter-like area to Colorado on Sunday. There will be enough moisture with the system that a round of snow looks likely Sunday, perhaps lingering into early Monday.
As of now, accumulations are expected to be light, and it should be over well before Monday morning’s commute. Unlike Wednesday night’s storm, though, temperatures will be colder, with . That likely means that any snow that does fall will stick to roadways, and that could impact travel on Sunday.
Temperatures through the rest of October should remain extremely cold, and there will be another chance for light snow on Tuesday into Wednesday.
A dominating – and persistent – ridge of high pressure across the northeastern Pacific Ocean is helping steer colder air across much of the continental United States this week.
Just an impressive Pacific Rossby wave train seen in the upcoming 15-day aggregate with Greenland Blocking. The big ridge over the Northeast Pacific will keep the cold air flowing across the Rockies and Plains, with volatile conditions over the East.

Beyond this weekend’s snow event, and perhaps more significantly, there are hints that this Halloween may be one of Denver’s coldest on record, according to one forecast model. But there’s high uncertainty in the forecast at this point.
In any case, you might want to hand out hand warmers instead of candy this year.
Still a full week out, but coldest Halloween on record in Denver could be in play.
Coldest Halloween max high: 17°, 2002
Coldest Halloween low: 10°, 1991Current Euro forecast: 21°, with a low of -5° (could be Fri. AM, but would likely break it either way).
