A potent late-season spring storm is bringing heavy, wet snow to the Colorado Front Range and parts of Wyoming.
The storm creates significant hazards for travel and infrastructure, as a sudden temperature drop risks a hard freeze for regional vegetation and agriculture.
The National Weather Service issued a Winter Storm Warning, while the 9NEWS Weather Impact Team issued a Weather Impact Alert [1]. The system is driven by a powerful cold front moving south from Canada, which dropped temperatures from the 70s to below freezing [4, 5].
Snowfall totals vary significantly by elevation. The Denver metro area is forecasted to receive between four and eight inches [2]. However, other locations in Colorado could see up to 24 inches [3], while some parts of Colorado and Wyoming may receive as much as 30 inches [4].
The timing of the storm's impact has seen some variation in reporting. The Winter Storm Warning covers the period from Tuesday evening through Wednesday afternoon [1]. Other reports indicate travel impacts will persist through Wednesday, with some forecasts extending the effects into Thursday [3, 6].
The heavy nature of the snow, combined with the rapid temperature shift, increases the risk of downed power lines and tree damage in the foothills. Local authorities said they continue to monitor the Front Range as the storm progresses through the week.

This event represents a volatile weather swing common to the Rocky Mountain region, but the timing is particularly disruptive. A sudden shift from spring temperatures in the 70s to below-freezing levels can cause significant crop loss and stress urban infrastructure not prepared for heavy, wet snow in May.
