Cold Blast for Colorado

29 Oct 2017, 7:06 pm

Sunny, warm and dry weather across Colorado on Sunday turns cold and snowy for the start of the week. Locations in Colorado, especially east of the Continental Divide, will see dramatically different conditions that could require a heavy coat and snow scraper Monday morning.


Denver Sunday Afternoon

 Late Sunday, expect colder air to push into the Four Corners dropping temperatures and also changing the prevailing wind direction.  Behind the cold front winds will shift northeast bringing an up slope flow to eastern Colorado.  

Drizzle or light rain is expected in Denver by 12am Monday changing over to snow by around 3am.  Snowfall amounts should be less than 1” in locations around the Denver Metro by noon on Monday. Freezing drizzle is a concern on roadways but with the very warm temperatures in Colorado on Sunday accumulation should be minimal or not a factor.

The cold air will inundate areas south of Denver a little later and Freezing drizzle could impact travel along I-25 over Monument hill early Monday.  Daytime highs Monday afternoon along the I-25 corridor are expected to make it to the freezing mark, for an almost 40° dip from Sunday.


A secondary wave of energy moves across western Colorado Monday evening with increasing chances of rain and snow for the central and southern mountains and southeastern Colorado.  

The National Weather Service has issued Winter Weather Advisories for the West Elk and Sawatch Ranges, as well as the San Juan Mountains, for Monday night and through much of the day Tuesday for elevations above 9,000 ft.

Above 9,000’ snowfall will range from 5 to 10 inches with locally higher amounts while lesser amounts of 2 to 5 inches will be possible below 9,000’.
