Denver can expect mostly sunny conditions Wednesday and a high near 78, with temperatures near 51 Wednesday night. The pleasant stretch continues Thursday and Friday, but the forecast takes a decidedly fall-like turn Saturday as rain chances rise and temperatures drop nearly 25 degrees.

Warm Weather Holds Through Friday

Wednesday afternoon should stay dry with light south and southeast winds, while Thursday brings partly sunny skies and a high near 77. Friday is expected to reach about 80 under mostly sunny skies, though winds could become breezier across parts of the region.

The National Weather Service in Denver/Boulder says lower elevations will remain warm and mostly dry through Friday, with cooler and more unsettled weather arriving this weekend. No watches, warnings or advisories are posted for the Denver area.

Weekend Brings Showers And A Sharp Cooldown

Saturday tops out near 58 with a chance of rain showers, followed by a colder, cloudier night near 39. Sunday stays cool around 58 with another chance of showers, while Monday brings a slight chance of showers and partly sunny skies.

Friday looks like the easiest day for outdoor plans, while Saturday and Sunday call for a light jacket and a backup plan. The forecast turns milder again Tuesday, when mostly sunny skies and a high near 62 are expected.
