Colorado faces midweek snow and rain

Colorado is getting the classic spring fake-out. It was warm over the weekend, but now a colder system is moving in and dragging rain, wet snow, and mountain travel problems behind it. The big story is timing — Tuesday into Wednesday looks like the window when the Front Range cools enough for a rain-snow mix, while the high country picks up more meaningful snow. That matters because early-May storms hit differently in Colorado: people are thinking spring, but roads can still turn winter fast. ### Where is the snow actually going? The deepest snow looks more likely in the mountains and foothills, not downtown Denver getting buried. The National Weather Service office in Boulder flagged widespread precipitation from Monday through Wednesday, with increasing confidence in moderate to heavy mountain snow and travel impacts there. Local forecasts. ### What does that mean for Denver? For Denver, this is less “big blizzard” and more “messy, cold, and changeable.” The city starts with rain or a rain-snow mix, then some areas can flip to accumulating wet snow as colder air settles in. The current Denver forecast page shows a Winter Storm Watch from Tuesday evening, May 5, through Wednesday afternoon, May 6, which tells you forecasters think impactful snow is plausible even on the plains. ### Why is this storm a bigger deal in the mountains? Elevation does the work. A storm that is mostly rain in Denver can be a solid snow event along the I-70 corridor and over the passes. The forecast discussion specifically calls out significant travel impacts in the mountains, and Colorado’s transportation agency keeps warning that the I-70 mountain corridor can go from dry pavement to white-knuckle driving. ### What should drivers watch for? The first problem is slick roads during the transition period — when rain turns to wet snow and temperatures hover near freezing. The second is visibility, especially in foothill and mountain bands where snowfall rates can pick up fast. CDOT says drivers should check COtrip before heading out, and traction or chain laws can be activated when conditions warrant. Those rules stay in Colorado’s toolkit through May 31. ### Is this unusual for May? Not really — but it still catches people off guard. Colorado regularly gets spring storms after warm stretches, and this setup is exactly why. The same forecast cycle that had above-average warmth for Sunday also had unsettled weather returning Monday night through Wednesday, with snow possible on the plains and a 60% chance of significant mountain accumulations. Spring here is basically winter and summer arguing in public. ### What should outdoor plans account for? Cold rain on the plains and fresh snow in the high country can change hiking, camping, and road-trip plans fast. Trails can turn muddy or slushy, and higher elevations may feel much more wintry than lower-elevation forecasts suggest. If you are heading into the mountains, assume conditions will be worse than they look from the city and build in extra time. ### When does it improve? The rough patch looks centered on Tuesday and Wednesday. After that, forecasts point to improving conditions and a return to drier, milder weather later in the week. So this is probably a short, sharp reminder that Colorado’s snow season is not done just because the calendar says May. If you are staying in town, expect a gray, colder couple of days and the chance of slushy commutes. If you are driving into the mountains, treat this like a winter trip, not a spring one.
