Less than a week after Denver's first snowstorm of the season, another storm is set to bury the city again Tuesday night into Wednesday., put folks in Colorado on notice for the possibility of another snowstorm last week.

If two snowstorms in one week weren't enough, there is even the potential for third storm to follow this weekend.

Storm Setup and Accumulations in the Northern Rockies

Monday's sunshine and mild 70-degree temperatures will be replaced with several inches of snow, brisk winds, clouds and lows in the 20s Tuesday night.

A strong disturbance will carve its way southeastward from the Pacific Northwest into the central Rockies Tuesday.

In response, snow will break out throughout the day Tuesday across south-central Montana, much of Wyoming and northern parts of the Wasatch Range in Utah.

By Tuesday evening, heavy snow will be falling in such cities as Cheyenne, Lander and Laramie, Wyo., while snow begins to break out in Denver.

The heaviest snow for the Denver Metropolitan area is expected Tuesday night through early Wednesday morning, when snowfall rates can exceed an inch or two per hour.

Snow totals in the Denver metro area are expected to reach 4 to 8 inches with this quick-hitting storm. Up to 16 inches is forecast for the foothills, while the high country picks up even greater amounts.

Snow totals in Cheyenne, Lander and Laramie will likely be similar to Denver with 4 to 8 inches of accumulation.

Temperatures throughout this storm will be 5 to 10 degrees colder than last week's storm. The lower temperatures could lead to more in the way of accumulations and impacts on area roadways. Travel could quickly become hazardous in some of these areas Tuesday and Tuesday night.

Commuters can expect delays along the major I-25, I-70, I-80 and I-225 corridors and should allow extra time if travel is necessary. Travel will become treacherous through the mountains and foothills with road closures a strong possibility.

Airport delays are likely to develop at airports from Lander to Denver International with ripple effects across the country.

The snow will threaten to cause power outages again. Trees across the Denver area still have leaves on them, if they weren't damaged during the last snowstorm. The snow will cling to and weigh down branches as the temperature dips.

Another Snowstorm This Weekend??

Residents of Denver shouldn't get all that excited about the milder temperatures forecast after this first snow Thursday and Friday, as another storm could bring accumulating snow for many over the weekend.

A shot of cold air is set to spread into the western part of the country beginning Thursday. Along with that, snow levels will be falling below pass level in the Washington and Oregon Cascades.

Similar conditions will be found all the way into the Sierra Nevada range by Thursday night.

As this feature tracks through the Intermountain West, it could send another round of snow into Denver, Cheyenne and Laramie by Saturday.

Although the storms are still a few days away, meteorologists will continue to monitor this double snowstorm potential for Denver and surrounding areas.
