The Denver area’s hot, sunny weather turned stormy and cooled down by mid-afternoon Sunday, with winds picking up and thunderstorms rolling through.

The National Weather Service in Boulder said Sunday’s high temperature reached 91 before the rains started slightly before 3 p.m. The temperature dropped to the low- to mid-80s.

Meteorologist Bruno Rodriguez said the Denver area would likely see scattered showers and thunderstorms through the evening, mainly west of Interstate 25.

As of Sunday afternoon, rain amounts totaled a few hundredths of an inch to about 0.2 of an inch.

A  special statement by the weather service said the Denver area stretching from Commerce City to Castle Pines could get wind gusts of up to 50 mph.

Some of the storms over the mountains could be slow-moving and unleash enough rain to cause minor flooding in areas scarred by wildfires. A flash-flood warning was issued for the Cameron Peak burn area in Larimer and Jackson counties, but Rodriguez said there were no reports of flooding by afternoon.

The weather service said there will be a limited risk of flooding Monday in the East Troublesome burn area in Grand County and the Cameron Peak burn area.

There is a 10% chance of storms and showers will continue until around 9 p.m. Sunday, but the weather is expected to gradually clear. The Denver-area’s low temperature will be 61 degrees.

Labor Day’s forecast calls for sunny, breezy weather with a high of 91 degrees and a slight chance of showers and thunderstorms before 9 p.m.
