Denver is starting Tuesday clear and around 61 degrees, with a west-southwest breeze already moving through the area. Skies will turn mostly sunny as temperatures climb to about 87 degrees this afternoon, making for an easy outdoor day before a hotter stretch settles in.

The National Weather Service Denver/Boulder office expects warmer and drier conditions from Tuesday through Friday. Any storm development should be limited, with the best chances over the higher terrain and only a slight possibility across the plains.

The Heat Builds Through Friday

Wednesday will be sunny with a high near 91, followed by a hotter Thursday topping out around 93 degrees. Friday stays sunny and warm near 92, while overnight lows remain relatively comfortable in the low 60s.

Winds should generally stay light, though Wednesday could bring gusts up to 17 mph and Thursday may see breezier conditions during the day. For anyone planning errands, patio time or a late-summer hike, the morning hours will offer the mildest temperatures before the afternoon heat peaks.

Weekend Storm Chances Creep Back In

Saturday remains mostly sunny and warm near 92 degrees, but moisture begins returning to the region. Sunday brings a 30% chance of showers and thunderstorms after noon, with a similar setup expected on Labor Day Monday as highs reach about 91.

No weather watches, warnings or advisories are listed for the Denver area in the current forecast. Outdoor plans can still go forward, but weekend events should keep an eye on the sky after lunchtime, when storm chances are highest.
