Months of summer-like weather in Colorado will end this weekend with feet of snow in the forecast, along with rain and cooler, autumn-like temperatures.

A slow-moving storm system will bring chances of accumulating snow back into Colorado this weekend, especially over the high mountain passes in the southwest part of the sate.

A Winter Storm Warning is in effect from 6 a.m. Friday to Sunday at 12 p.m. for the San Juan Mountains. Heavy snow is possible with total snow accumulations of 1 to 2 feet possible above 9,000 feet. Winds could gust as high as 40 mph.

Additionally, eastern portions of the San Juan Mountains, as well as portions of the Sangre de Cristos, are under Winter Weather Advisories for up to a foot of new snowfall.

The National Weather Service said travel in southwest Colorado could be very difficult to impossible as roads, and especially bridges and overpasses, will likely become slick and hazardous.

The 9NEWS Weather Impact team is also tracking rain showers and colder temperatures along the Front Range, eastern plains and Denver metro area on Friday and Saturday.

The system is forecast to bring rain showers to the Denver metro area with high temperatures in the low 60s on Friday and low 50s on Saturday in Denver. The high temperature on Saturday may not break 50 degrees on Saturday.

Rain showers will gradually spread across the Front Range Friday afternoon, with the bulk of the widespread rain showers likely beginning Friday evening or Friday night and lasting into the day on Saturday.

Expect a cold and dreary day on Saturday with lows in the middle 30’s. The first freeze is not in the forecast for Denver, but it may come very close. Snow accumulation also remains very unlikely in Denver.

Temperatures start to rebound, Sunday, with Denver highs returning to the lower 60s. Precipitation will start to move out, clearing out of Colorado by the overnight hours.

As we start the next workweek, sunny and mild conditions return. We’ll see the return or dry, sunny skies and highs in the lower to middle 70s.
