A Winter Weather Advisory has been issued for parts of north-northwestern Colorado from 7 p.m. Sunday to noon Monday, the National Weather Service says.

The advisory has been issued for nearly all of Rocky Mountain National Park, the Medicine Bow-Routt National Forest, and the eastern edges of Garfield and Rio Blanco counties.

While not as serious as an Ice Storm Warning or a Winter Storm Warning, NWS says a Winter Weather Advisory is issued whenever freezing rain is expected or 2 - 4 inches of snow is in the forecast. The weather is expected to cause a significant inconvenience but isn't expected to be serious enough for a 'warning'.

Despite most places in Colorado experienced a mild December Sunday - with highs in the Denver area reaching 64 degrees - a cooldown is headed to the Rocky Mountain State Monday - with highs just tapping 40 and an overnight low of 19.

A quick burst of snow is expected in the mountains Sunday night into Monday morning, according to the National Weather Forecast. Up by the Wyoming border, nearly 8 inches is possible.

Wind gusts are also a concern heading into the overnight hours, with 30-50 mph gusts common throughout the mountains and foothills. The winds are expected to die down later in the day on Monday.
