Denver weather: Not as hot in the Front Range, but smoke and rain return – The Denver Post

Denver won’t be quite as hot Thursday. The changing weather pattern will add some moisture back into the mix this weekend, but first, another day with poor air quality is here.

According to the National Weather Service in Boulder, Denver will hit a high of 89 degrees Thursday with the sun pushing through areas of smoke.

The Colorado Department of Public Health and Environment issued a warning for multiple pollutants in the air. Ozone and fine particulate concentrations from wildfire smoke are expected to be unhealthy for sensitive groups, meaning an increased likelihood of respiratory symptoms in sensitive individuals. It is the 40th straight day the metro area has had an air quality alert. IQAir forecasts Denver’s air could be healthy for all Friday, which would buck the near six-week trend.

Thursday begins a new weather pattern with monsoonal moisture re-entering the fray, NWS says. The systems that bring heavy afternoon rains could dominate the forecast by early next week. For Thursday, there will be a 10% chance of thunderstorms before midnight, with 17 mph wind gusts and a low temperature of 62 degrees.

The threat of burn scar flash floods restarts on Friday and lasts through the weekend. Downtown Denver will push to 88 degrees under sunny skies. Thunderstorms have a 50% chance of developing after lunchtime, with the threat lasting until midnight. The overnight low is forecasted at 60 degrees.

A high of 90 is forecasted for Saturday, with a 20% chance of afternoon showers. The skies will clear in the evening with a low of 62 degrees.
