An Air Quality Warning remains in effect for all of northern Colorado.

A combination of smoke particles from western wildfires and moderate to high levels of surface ozone will continue to make conditions unhealthy for sensitive groups.

Some of the smoke is from Colorado fires, but much more is from the bigger fires to the west of our state. The heavier smoke will actually make any outdoor activities a concern, even for people without any underlying medical conditions. Heavy outdoor exercise is not recommended through Sunday!

In recent days, Denver has consistently ranked as one of the the worst cities in the world for air quality, according to a real-time air quality information platform on IQAir's website.

Hot and dry weather will continue across the majority of Colorado for the next five days. Highs temperatures will climb into the 90s each day this week, with 80s in the mountains. Wednesday may even hit 100 degrees in Denver! The record high for August 11th is 97 degrees, set last year and in previous years.

A few gusty thunderstorms are possible each day, mainly over the mountains and foothills. These storms will produce little rain, but instead cause lightning and gusty winds.

By Friday and through next weekend a weak monsoon flow will return to Colorado, cooling temperatures slightly and bringing a better chance for thunderstorms with locally heavy rainfall.
