This week’s beautiful weather will last into Memorial Day weekend — but it might not last very long.

Colorado’s western mountain region is expected to see highs in the 70s and lows in the 30s from Saturday into Monday. The highest reaches of the state, like Breckenridge, will see highs top out around 65 degrees, but areas with lower valleys, like those in Garfield County, will reach past 80 degrees — which is warmer than what Colorado typically experiences around Memorial Day weekend.

“Temperature-wise, we’re running about 5-10 degrees above normal, which isn’t outrageous,” National Weather Forecaster Brianna Bealo said. “We’re not talking record-setting weather, but it’s a little bit unusually warm for Memorial Day weekend.”

While the first half of the weekend will boast clear skies and sun, forecasters with the National Weather Service office say some of the region’s higher elevations could see rain showers with a 40-60% chance of precipitation on Sunday afternoon. Thunderstorms and lightning are possible. 

The National Weather Service posted a Hazardous Weather Outlook on Friday warning of hot, dry and windy conditions — the ideal conditions for fires to spread quickly.

“Definitely be smart about any sort of outdoor burning,” Bealo said. “With bonfires, barbecues, that kind of thing, be very aware of straight sparks and windy conditions that could blow embers off of any of those.”

The western half of Colorado saw critical fire weather conditions for most of the day on Friday, with several counties announcing a Red Flag Warning and asking people not to light fires outdoors. Winds reached up to 40 mph around the region.

Dry and windy conditions into the 30 mph range are expected to continue through Saturday. Fire weather watches will be in place for western Colorado on Saturday afternoon, thanks to high winds and low relative humidities.

The chances of showers and thunderstorms will pick up slightly on Saturday afternoon over northwest Colorado, though Bealo said the majority of the region likely won’t see rain until Sunday.

Rain will remain in the forecast in the afternoons for most of next week, Bealo said.
