Another day of record-breaking heat hit Colorado’s Front Range and Eastern Plains on Sunday, with temperatures climbing above 100 degrees, according to the National Weather Service.

Temperatures in Denver reached 103 degrees Sunday afternoon, weather service meteorologists announced shortly before 4:45 p.m. The heat broke Denver’s previous July 26 record of 100 degrees, set in 1910, according to weather service records.

“We expect similar records to be confirmed across the Front Range for today,” weather service officials wrote in the announcement.

The heat is expected to remain in the triple digits in Denver until 6 p.m. and drop back below 90 degrees after 8 p.m., according to hourly forecasts from the weather service.

An overnight low of 72 degrees is expected in Denver, more than 10 degrees above normal for this time of year, according to the weather service.

“Hottest day of the year,” weather service forecasters wrote on social media. “Take it easy and stay well by seeking shade, avoiding strenuous activities, staying hydrated, and checking on those without AC, including pets and livestock. Seek immediate medical aid if you fall ill due to heat.”

The weather service’s Boulder office issued a heat advisory on Sunday, which will be in effect until 9 p.m. The advisory covers Adams, Arapahoe, Boulder, Broomfield, Denver, Douglas, Jefferson, Larimer and Weld counties.

Triple-digit heat will also affect valleys in western Colorado, according to the weather service’s Grand Junction office. A separate heat advisory that covers the Grand Junction area and northwestern corner of Colorado, as well as parts of eastern Utah, will be in effect until 6 a.m. Tuesday.
