The score above is based on current snowfall, temperature, and wind data for the location you searched, weighted for your school type. Denver Public Schools (DPS) makes the actual closure call through a team decision, not a single administrator, and the storms that catch Denver off guard tend to work differently than the ones most people picture when they think of Rocky Mountain snow.
Why Denver's worst snow doesn't come from the mountains
Most Pacific storms lose their moisture crossing the Rockies and arrive in Denver already dried out. Denver's heaviest snow instead comes from upslope storms, a different setup entirely: a low-pressure system parked over southeastern Colorado spins counterclockwise, pulling moisture up from the Gulf of Mexico into the Front Range from the east. As that moist air rises over the terrain approaching Denver, it dumps its load right where the city sits, sometimes while the mountains 100 miles to the west stay completely clear.
The National Weather Service's Boulder office documented exactly this kind of split during the March 13-15, 2024 storm. Parts of south and west Denver picked up 14 to 22 inches, while Denver International Airport, in the northeast corner of the metro, logged only 5 to 10 inches from that same system, largely because rain there didn't switch over to snow until the following morning. It's not a new pattern. One of the most cited local examples is the October 1984 Monday Night Football game between the Broncos and Packers at Mile High Stadium, played in an upslope snowstorm while Aspen and Vail, roughly a hundred miles west, had clear skies that same day.
How Denver Public Schools actually decides
DPS uses a collaborative process spanning transportation, facilities, communications, and district leadership, weighing National Weather Service reports, real-time conditions, and how far along road crews are with plowing. The options on the table are running school as scheduled, delaying the start, cancelling entirely, or, least commonly, releasing early. Scott Pribble, DPS's director of external communication, described the district's actual standard to 9News this way: "That's the primary impetus behind any decision about weather: can we do that safely?" When snow spans multiple days, DPS reassesses each morning separately, so a Thursday closure doesn't automatically predict what happens Friday.
What goes into the Snow Day Score for Denver
Because upslope storms can produce such different totals within the same metro area, DIA and south Denver saw a roughly 10-inch gap during the March 2024 storm alone, the specific location you enter matters more in Denver than it would in a city with more evenly distributed snowfall. The calculator weighs snowfall, temperature, wind, and the timing of when precipitation is expected to switch from rain to snow, alongside your school type. That rain-to-snow transition point is worth paying attention to here specifically, since it's often the difference between a light dusting and a genuine closure-level storm on the same day. As with every SnowDayScore prediction, this is an estimate to help you plan, not DPS's own announcement.
Denver Snow Day Quick Reference
| Factor | What Denver Public Schools does |
|---|---|
| Who decides | A team spanning transportation, facilities, communications, and district leadership |
| Factors weighed | NWS reports, real-time conditions, road and plowing status, student and staff safety |
| Options | School as scheduled, delayed start, full cancellation, or, rarely, early release |
| Why storms are uneven | Upslope storms pull moisture from the east, so one part of metro Denver can get buried while another stays nearly dry |
| Multi-day storms | Each day is reassessed separately as conditions change |
Frequently asked questions
Why does it sometimes snow hard in Denver while the mountains nearby stay clear?
Denver's biggest storms are usually "upslope" events, where a low-pressure system pulls moisture from the Gulf of Mexico into the Front Range from the east rather than from the Pacific side, the opposite direction most Colorado storms travel from.
Does all of metro Denver get the same snow totals in a storm?
Not usually. During the March 2024 storm, south and west Denver suburbs picked up 14 to 22 inches while Denver International Airport, in the northeast metro, logged only 5 to 10 inches from that same system.
Who actually makes the closure decision at Denver Public Schools?
A team that includes transportation, facilities, communications, and district leadership, weighing weather reports, road conditions, and safety together, rather than one administrator deciding alone.
If Denver Public Schools closes Thursday, does that mean Friday is closed too?
Not automatically. DPS reassesses conditions fresh each morning during multi-day storms, so a Thursday closure doesn't guarantee the same call the next day.
