Unseasonable May Snow Hits Colorado Mountains Following Record-Warm Winter
Colorado’s high country experienced a dramatic return to winter conditions on May 1, 2026, as a powerful storm system dumped significant snowfall across the state’s mountain ranges. The event comes as a stark contrast to a winter season that was the warmest on record for the state, leaving residents and travelers grappling with hazardous road conditions and a reminder of the Rockies’ volatile spring weather.
- Heavy Accumulation: Some mountain peaks saw total potential accumulations reaching up to 22 inches, with the Pikes Peak summit forecast to reach as much as 35 inches over three days.
- Travel Disruptions: Winter Storm Warnings triggered severe conditions across the I-70 corridor, including Eisenhower Tunnel and Vail Pass.
- Drought Context: Despite the fresh snow, statewide snowpack remained at just 20 percent of the median as of May 1, 2026.
- Temperature Swing: The storm follows a winter where Colorado’s average temperature between December and February was 33.6 degrees, nearly 2 degrees warmer than the previous record.
Storm Totals and Regional Impact
The National Weather Service issued winter storm warnings across the Sangre de Cristo and Wet Mountains, warning of heavy snow and freezing temperatures. While urban areas on the Front Range saw a mix of rain and light snow, the mountains bore the brunt of the system.
According to reporting from Summit Daily, forecasters expected between 5 and 13 inches of snowfall, with the highest totals concentrated in the Mosquito Range and along the Front Range. In more extreme high-end scenarios, the Denver Gazette reported that some areas along the I-70 corridor east of the Eisenhower Tunnel could see 12 to 18 inches, while the hardest-hit peaks could reach 24 to 30 inches.
“The truth of the matter is that we’ve been so dry that it does feel wet right now, but it’s not going to be enough to move the needle because this is not a storm that has excessive amounts of water wrapped up in it.” Lucas Boyer, National Weather Service Meteorologist
Hazardous Travel and Road Conditions
The timing of the storm created treacherous conditions for motorists, particularly those who had already transitioned to spring tires. The Autoblog report highlighted severe ice and snow across the I-70 high country, with traction laws in effect between Silverthorne and Bakerville.
Specific impacts included:
- I-70 Corridor: Severe snow and ice reported from Eagle to Vail and through Vail Pass.
- Pikes Peak Region: Additional accumulations of 5 to 10 inches were expected on east-facing slopes of the Rampart Range.
- Mountain Passes: Raton Pass and the Eisenhower Tunnel were identified as high-danger zones during the overnight window of the storm.
A “Dry” Snowfall: The Drought Crisis
While the visual of a foot of May snow is striking, meteorologists warn that the event does little to alleviate a critical water shortage. Data from the USDA Colorado Snow Survey confirmed that as of 12:00 a.m. On May 1, statewide snowpack was only 20 percent of the median.
This deficiency is the result of a historically hot and dry winter. 9News Senior Meteorologist Chris Bianchi noted that the average winter temperature of 33.6 degrees—the warmest ever recorded for the state—led to a rapid snowmelt and record-low snowpack levels. Much of the Western Slope remains under extreme
(Level 3 of 4) or exceptional
(Level 4 of 4) drought conditions according to the U.S. Drought Monitor.
Looking Ahead: Super El Niño and Future Forecasts
The current unsettled pattern is expected to continue into the first week of May. Forecasters are tracking additional precipitation possibilities for Monday night and Tuesday. Looking further ahead, meteorologists are monitoring the potential for a super El Niño
later in 2026, a climate pattern that historically brings wetter winter conditions to Colorado and could provide much-needed relief to the state’s depleted reservoirs.
Frequently Asked Questions
Is it normal to have a foot of snow in Colorado in May?
While not common, measurable snowfall in April or May has occurred in Denver in each of the last 30 years. However, totals exceeding a foot are generally restricted to high-altitude mountain peaks and passes.
Will this storm end the drought in Colorado?
No. According to the National Weather Service, while the moisture is welcome, the current drought is so severe that this specific storm is not expected to significantly change the overall drought status.
Which roads are most affected by the May 1 storm?
The I-70 mountain corridor, including Vail Pass and Eisenhower Tunnel, as well as US-24 between Colorado Springs and Woodland Park, have seen the most significant impacts.
