On average at this time of year, temperatures in the city hover around 87 degrees, but the heat is still six degrees away from beating Denver’s hottest June 25 ever, according to NWS data. The current record is 105 degrees, set in 2012.

Out east in the plains, temperatures will hit 100 degrees again Tuesday, especially around Fort Morgan and Sterling, NWS forecasters said.

Isolated thunderstorms and rain showers will start in the Denver area after 3 p.m., bringing the threat of up to 40-mph wind gusts, forecasters said in a hazardous weather outlook.

“Moisture is expected to increase Wednesday and Thursday, bringing better chances for showers and thunderstorms, some of which could be strong to severe and produce large hail and heavy rain,” the outlook stated.

Heat advisories will continue across the metro area until 9 p.m. Tuesday, according to NWS forecasters. The hot temperatures could cause heat-related illnesses.

“Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors. If you must be outdoors, take frequent breaks from work or activities,” forecasters said in the heat advisory.

The Colorado Department of Public Health and Environment also issued an Ozone Action Day Alert for the Front Range Urban Corridor, including Douglas, Jefferson, Denver, Arapahoe, Adams, Broomfield, Boulder, Larimer and Weld counties.

Increased ozone concentrations and hot, stagnant weather could create unhealthy air quality conditions Tuesday afternoon and early evening, the alert stated.

State officials said people in the affected counties should limit driving gas and diesel-powered vehicles until 4 p.m. Tuesday. The highest ozone concentrations are expected to be in and near the Denver metro area.

Tuesday should be the peak of the heat, and a gradual cooling trend is forecasted through the rest of the week, NWS forecasters said. Temperatures are expected to dip down to a high in the mid-80s Saturday before jumping back up into the 90s Sunday and Monday.
