Denver woke up to clear skies and a mild 59°F Monday morning, May 25, and the city is headed for a toasty afternoon. Temperatures are expected to climb into the mid-80s with a high near 86°F, with mostly sunny skies to start before a chance of showers and thunderstorms pops up after about 3 p.m. The evening will cool back into the mid-50s, with a few lingering clouds hanging around overnight.
Afternoon Storms Could Bring Strong Gusts
Scattered, mostly high-based showers and a few thunderstorms are most likely in the mid to late afternoon and early evening, with the best odds across the eastern plains and near the foothills. Any stronger storm could deliver a quick, heavy downpour and strong outflow winds that jump well above the usual afternoon breeze. The forecast discussion from the National Weather Service Denver/Boulder warns that these high-based cells may produce gusts of 40 to 50 mph.
Plan For Races And Outdoor Events
Morning races and ceremonies, including the BOLDERBoulder in Boulder, should enjoy plenty of early sunshine. By the time finishers are rolling in and afternoon crowds gather, though, spotty showers or a passing thunderstorm could move through. If you are heading to a parade, park party, or campsite, it is worth having a quick shelter plan for lightning and sudden gusts, and you may want to shift activities earlier in the day.

What To Expect This Week
Forecasters expect the warm pattern to stick around through the week, with daily afternoon and evening chances for showers and a few thunderstorms. Tuesday looks windier on the plains, with the potential for elevated fire weather where areas stay dry, and Wednesday may bring the most widespread storms. That outlook comes from the National Weather Service Denver/Boulder forecast discussion. If you have outdoor plans later in the week, keep an eye on updates and secure loose patio furniture before those breezy afternoons kick up.
Bottom line: enjoy the sunshine this morning, but be ready for a pop-up storm this afternoon, move plans earlier if you can, and keep a weather app or radio handy for fast updates. If you are driving, slow down in heavy rain and give emergency and race-control vehicles plenty of space during closures and crowded exits.
