Enjoy the warm, sunny autumn week ahead, Colorado. Next weekend will remind us thatwinter's on the way, according to forecasters.

After Denver moves into striking range for record high temperatures at midweek, temperatures are expected to plummet to near freezing with a slight chance of snow next weekend, forecasters said Sunday.

The National Weather Service expects the city to reach 64 degrees Monday. After a forecast high of 72 on Election Day in Denver, Wednesday could hit 74, which is 4 degrees short of the record high for the date set in 1999.

Forecasters expect Thursday to top out at 67, followed by 65 Friday. Saturday, however, could reach only 41 degrees with a slight chance of snow, then just 33 on Sunday. (The city's coldest high temperature on record for Nov. 11 is 19 degrees in 1916.)

Western Colorado's weatherwill ride the same arc as Denver's with warm, sunny days this week giving way to chilly temperatures and snow as a cold front approaches from the northwest.

Steamboat Springs will have highs in the 50s this week, then could reach just 36 on Saturday and 26 Sunday. Aspen is expected to be in the 40s this week, but could reach a high of just 24 Saturday and 16 Sunday. Durango will be warmer, with high temperatures in the 60s through Friday, then around 40 degrees each day next weekend.

The system could bring much-needed snow to the high country, as thestate's snowpackcontinues to lag behind for a second year in a row. Statewide snowpack Friday was just 55 percent of its 30-year average for this time of year, and jut 59 percent in the ski resort-heavy Colorado River basin.

Denver, however, received 5.5 inches of snow during October, which was 1.5 inches above the average of 4 inches.

After March, November is Denver's second-snowiest month, averaging 8.7 inches annually since 1981, according to the National Weather Service.

"November also has the capability to produce big snowstorms," the agency stated in its monthly weather outlook. "The biggest snowstorm Denver received during the month of November was a powerful three-day event that dropped 30.4 inches of snow from November 2nd through the 4th of 1946. The second heaviest snowfall event for November occurred in 1983. That four-day event gave the city 22.4 inches from the 26th through the 29th."
