A heavy, wet May snowstorm buried parts of Colorado and Wyoming this week, piling more than 20 inches of snow across higher elevations of the Rockies and shutting down schools in Denver, all after the driest winter on record left the region parched and desperate for moisture.
Boulder, Colorado, took the brunt of it. More than 10 inches fell there by early Wednesday, weighing down trees and turning roads slick. FOX Weather reported that the storm marked Boulder's biggest May snowfall since 2013. Denver International Airport tallied 4.7 inches by mid-morning Wednesday, with 1 to 3 more inches still in the forecast.
Winter Storm Watches and Warnings stretched along the Interstate 25 corridor from Cheyenne, Wyoming, south through Denver and down to Colorado Springs. Whiteout driving conditions remained possible along the I-70 corridor. The system was expected to peak Wednesday afternoon and exit by Thursday.
The storm's timing tells a story that Colorado residents already know too well. Denver typically sees just 1.4 inches of snow in May. Its April average is 6.2 inches. FOX Weather Meteorologist Marissa Torres said this could be Denver's biggest May snowstorm since 2003, when a system dropped 7 inches on the city.
But the real context is what came before: almost nothing. Kenley Bonner, a meteorologist in the National Weather Service's Denver office, put it plainly.
"We just had our driest winter on record. We were kind of joking earlier in the season that winter's not going to come until spring, and it did exactly that."
That quote, reported by the AP, captures the bitter irony facing the Front Range. A region that needed snow all winter long got it in May, when it does the least good for long-term water supply.
Colorado State University recently reported that the state's snowpack sits at just 38 percent of its 1991, 2020 average in drinkable water content. One late storm, however dramatic, cannot fix that deficit. The snowpack feeds rivers, reservoirs, and irrigation systems across the West. At 38 percent, ranchers, farmers, and municipal water managers face a summer of hard choices.
Colorado has braced for this rare May snowfall since forecasters flagged the system earlier in the week, but the scale still caught attention.
Denver Public Schools and other major districts and colleges canceled Wednesday classes because of the storm. The heavy, wet snow, driven by dense cold air behind a massive cold front combining with Pacific moisture, posed risks well beyond slippery commutes.
Meteorologists warned the wet snow could snap tree branches and cause power outages. The Washington Times reported that Xcel Energy placed 165 employees on standby to respond to potential outages. That kind of preparation signals how seriously utilities took the threat, wet May snow on fully leafed-out trees is a recipe for downed limbs and broken power lines.
FOX Weather Correspondent Robert Ray reported from Boulder early Wednesday, describing snow weighing down trees and slick conditions across the city. He also noted that Arapahoe Basin ski resort, which had already closed for the season, planned to reopen this weekend through May 10 to take advantage of the fresh powder.
That detail, a ski area reversing its seasonal closure, underscores just how unusual this storm is. May skiing in Colorado is not unheard of, but reopening after shutting down for the year speaks to the volume of snow that fell.
The storm swept from the Rocky Mountains into the High Plains, hammering northern Colorado and southeastern Wyoming hardest. Forecasts called for Boulder to receive more than a foot of snow total, with Denver seeing up to 8 inches through Wednesday.
Whiteout conditions along the I-70 corridor posed serious danger to drivers. Colorado's mountain highways are no strangers to weather-related disasters. A seventy-vehicle pileup on a snowy Colorado interstate earlier demonstrated how quickly conditions can turn deadly on these roads.
The I-25 corridor, stretching from Cheyenne to Colorado Springs, remained under warnings as well. That stretch of highway has seen its own share of catastrophic weather events, including a fatal multi-vehicle pileup near Pueblo during high winds.
Images from the storm told the story in visual terms. Snow fell on Grant Street in Denver on Tuesday, May 5, 2026. In Castle Rock, south of Denver, accumulation piled up the same day. By Wednesday morning, Boulder looked like mid-January.
For a region suffering through historic drought, any moisture helps. But the math does not add up to relief. Colorado's snowpack at 38 percent of average means the state enters summer with a massive water deficit. Late-season snow melts fast in May warmth. Much of it runs off quickly rather than soaking into the ground or building the high-country snowpack that feeds rivers through July and August.
The broader pattern across the Plains and Mountain West this spring has been one of weather extremes. While Colorado dealt with snow, states to the south and east have faced severe weather outbreaks with damaging hail and tornadoes, a reminder that the atmosphere has been volatile across the region.
Denver's average May snowfall of 1.4 inches puts this storm in rare company. If the final totals approach 7 or 8 inches, it would rival or exceed the 2003 event Torres referenced. For a city that barely saw flurries all winter, the sudden dump of snow feels less like a gift and more like a taunt.
The system was expected to clear out by Thursday, returning the Front Range to something closer to normal spring weather. But the damage to trees, the disruption to schools and travel, and the broader drought picture will linger long after the snow melts.
One dramatic snowstorm makes for good television and reopened ski resorts. It does not refill reservoirs. It does not restore a snowpack that should have been building since November. And it does not change the fact that Colorado just endured its driest winter on record, a record that stands regardless of what fell this week.
Water policy in the West is a slow-motion crisis that no single storm can address. The 38-percent snowpack figure from Colorado State University should alarm anyone who depends on Colorado River water, Front Range municipal supplies, or agricultural irrigation. That number represents a structural shortfall, not a bad week.
For residents digging out Wednesday, the storm was an inconvenience and a hazard. For water managers looking at the summer ahead, it was a drop in a very large, very empty bucket.
Nature has a way of reminding people that weather is not policy, and that one late blizzard does not erase a season of failure by the climate to cooperate with anyone's plans.
