Denver is heading into another unseasonably warm October weekend, with clear skies and a high near 86 degrees Friday. The sunshine sticks around through Monday, while the first real cooldown of the week arrives Tuesday and brings a chance of showers by Tuesday night.

Denver Reaches The Mid-80s Again

Friday will be sunny, dry and warm, with south winds running 5 to 9 mph and a high near 86 degrees. Temperatures will ease only slightly Friday afternoon, and the overnight low will settle near 58 under mostly clear skies.

The National Weather Service in Denver and Boulder describes the stretch through the weekend as unseasonably warm, with mainly dry conditions across the lower elevations.

Weekend Plans Get A Sunny Forecast

Saturday will be mostly sunny with a high near 84 and southwest winds around 7 mph. Saturday night turns mostly cloudy but remains mild, with a low near 58.

Sunday brings partly sunny skies and another warm afternoon near 82 degrees, followed by a mostly clear night near 56. Monday stays sunny with a high around 81, making this a particularly friendly forecast for outdoor plans across the Denver area.

Dry Air And Breezes Raise Fire Concerns

The warm pattern comes with very dry air, and southwest breezes are expected to strengthen at times, especially Saturday. The National Weather Service says elevated to locally critical fire-weather conditions are possible in parts of the broader region, particularly across the eastern plains, although no watches or warnings are posted for Denver.

Residents heading outdoors should use extra care with anything that could spark a grass or brush fire. Even a light breeze can help a small fire spread quickly in these dry conditions.

Cooler Temperatures Arrive Tuesday

Tuesday marks the shift, with sunny skies but a cooler high near 75 degrees. Rain chances increase Tuesday night, when showers are possible under mostly cloudy skies and temperatures dip to around 49.

Wednesday brings a chance of rain showers, partly sunny skies and a high near 70. A smaller shower chance lingers Thursday, with mostly sunny conditions and a cooler high near 67.
