Colorado Weather: Cold fronts with lower temperatures, and the possibility of rain and snow

DENVER — An active weather pattern could bring Denver’s first measurable snow of the winter, and possibly send some flakes flying just in time for Halloween.

Denver’s first snowfall of the season is increasingly likely this weekend. Although it won’t be a huge storm, computer models are coming to a better agreement that at least some snow will fall in the Front Range, including Denver.

The system will also bring cooler temperatures to Colorado. Temperatures will drop into the 20s, maybe even teens on Sunday, Monday and Tuesday mornings (and maybe even beyond).

A sharp cold front will move through Colorado late Thursday, bringing with it an extremely cold air mass. Temperatures will drop from highs in the mid-70s on Wednesday to a high of only about 50 degrees on Friday.

But this is just the beginning.

Computer models are still figuring out the timing of this week’s storm, but at this point, it looks like snow could start as early as late Saturday. Snow is likely across the Front Range, including the Denver area, by Sunday. That could continue into Monday, but again, computer forecast models are still pinpointing the exact timing and impacts of this weekend’s storm.

At this time, there doesn’t appear to be much snowfall at lower elevations like Denver. There may be an inch or two of leaves on hand for most people, although details won’t come into focus until later in the week.

The biggest impact of this weekend and next week’s weather will likely be cold. Lows could drop to as low as the upper teens in the metro area (again, there is a lot of uncertainty around this), making a hard freeze almost certain and possibly enough to damage sprinklers.

Winterize your home this week if you can.

Even if there is only a little snow, the Broncos’ game Sunday against the Chiefs will likely have significant weather impacts this weekend. Increasing snow is likely during Sunday’s game, with very cold temperatures as well. Highs will likely only peak in the low to mid 30s in Denver on Sunday, with clouds and light snow.

There probably won’t be much (if any) accumulation of snow on Sunday, but we’ll have more details as the game approaches. But if you’re heading to the game, definitely plan on wearing a thick orange and blue jacket.

Given the uncertainty surrounding the storm and the fact that we are still more than a week away from Halloween, an accurate Halloween forecast for the Denver area remains a major challenge.

However, it sure looks cool. Depending on the timing of the storm system this weekend, it will be in the 20s or 30s on Halloween night.

It looks dry, though. However, you may want to have a warm Halloween costume – or a winter coat underneath!
