Hard Freezes, Heavy Snow and Power Outages Targeting Colorado and Wyoming Including Denver, Front Range and I-25 Corridor Tuesday Night Through Wednesday With 20s and Teens Thursday Morning
COLORADO — A significant and impactful storm system is spreading rain and snow southward across Colorado and Wyoming on Tuesday, May 5, 2026, with precipitation increasing and sliding south throughout the day. Rain changes over to wet snow tonight across most areas below 6,000 feet, with hard freezes arriving Wednesday and Thursday mornings bringing widespread 20s and 30s east of the Continental Divide. Downed power lines, power outages, and broken tree branches are all expected across the mountains, foothills, and potentially the Front Range and I-25 corridor.
Rain and Snow Spreading South Through Tuesday With Changeover to Wet Snow Tonight
Widespread steady precipitation is currently focused north of I-70, with scattered activity south of the interstate through Tuesday morning. Rain and snow will continue spreading southward throughout the day across Wyoming, the Nebraska Panhandle, and Northern Colorado.
By late tonight, most areas below 6,000 feet outside of the far eastern plains and far southeast Colorado should flip to wet snow. By Wednesday morning, snow will be falling across most of the region along and east of the Continental Divide.
Power Outages and Downed Lines Likely in Mountains and Foothills Through Wednesday
The highest accumulation potential sits across the mountains and foothills, where heavy wet snow loading on trees and power lines will create significant infrastructure impacts. Downed power lines, outages, and broken tree branches are expected across these elevated zones through Wednesday.
That same threat extends down to the Front Range and I-25 corridor if the rain to snow changeover happens early enough for accumulation to build on vegetation and surfaces.
Hard Freezes Expected Wednesday and Thursday Mornings With Widespread 20s and Teens
Wednesday morning will bring widespread temperatures in the 20s and 30s east of the Divide, with colder readings in the mountains. Thursday morning delivers a widespread hard freeze with 20s and teens east of the Continental Divide and low to mid 30s on the western slope.
Precipitation exits by late Wednesday night with temperatures recovering into the 60s and 70s by Thursday afternoon. Stay with NapervilleLocal.com for the latest weather updates and local forecast coverage.
