It is Denver’s snowiest month of the year, after all.
After highs in the 60s on both Tuesday and Wednesday of this week, a burst of snow will usher in some meteorological whiplash to the Front Range on Friday night. While snowfall amounts are expected to be light for most – or at least compared with last week’s impressive spring storm – there still could be some impacts to metro area roads on Friday night and into Saturday morning.
As of Thursday night, the National Weather Service in Boulder was calling for 1-3 inches of snow across most of the Denver metro area for Friday night. Winter weather advisories were only in place for the northern mountains, mainly covering Rocky Mountain National Park and parts of the Larimer and Boulder County foothills.

Clouds and mostly light rain will be in place for most of Friday, before the switch to a heavy, wet snow around dusk on Friday evening. The exact timing of the changeover will impact amounts, with the Palmer Divide and the western foothills favored to end up with the highest totals. Here, 3-6″ of snow could fall, mostly after dark on Friday and above 7,000 feet in elevation.

There is still, however, uncertainty in regards to the timing of Friday’s change from rain to snow, and where the bands of heaviest snowfall might set up. There’s a chance a higher-end scenario could produce 2-4″ of snow in Denver, although a lighter solution (1-3″) appears more likely.
“These type of systems, over the years, have been notorious for creating surprises and have been tricky to forecast,” the National Weather Service wrote in its forecast discussion on Thursday night.
