DENVER — The skies over Colorado are filled with haze and smoke from wildfires in Colorado and across much of the western United States.

An Air Quality Alert is in effect through at least 4 p.m. Tuesday. Ozone concentrations are expected to reach the Unhealthy for Sensitive Groups category.

On Tuesday, for the All-Star Game in Denver, the skies will remain milky white instead of our familiar brilliant blue. There will be sunshine filtering through the smoke and haze and there is a slight chance for a few gusty thunderstorms. Expect highs in the low 90s before the start of the game, with 80s closer to sunset.

Cooler weather will arrive Wednesday and Thursday as a weak cold front slips across the state. This front will bring higher humidity and a better chance for showers and thunderstorms and drop highs back to the mid-to upper 80s.

Air quality should improve a little with the increase in shower activity, but skies will still be rather hazy. The ozone concerns should lessen along the Front Range.

Hotter and drier weather will return starting Friday and continued through next weekend. Rain chance will be lower, and highs will rise into the 90s once again. Unfortunately, the smoke and haze will return to our skies once again and low level ozone will increase.
