Colorado residents have one more day of record heat before a weekend cooldown into the 60s.

Thursday’s forecast high is 100 degrees, which would break a daily record for a second day in a row.

Denver reached 99 degrees Wednesday, breaking the previous record for the day of 95 degrees set in 2013. Greeley saw the highest temperature in the area, with a record-setting 100 degrees that broke the previous record from 2000.

A heat advisory is in effect for most of the plains and the Interstate 25 corridor as temperatures could reach 104 degrees in other areas. A Red Flag Warning is also in effect for most of the plains east of I-25 until 8 p.m. Thursday as wind gusts could reach 35 mph.

Residents should drink plenty of water, stay out of the sun as much as they can and check up on relatives and neighbors.

Try to limit strenuous activities to early morning or late evening, and take action if you see any symptoms of heat exhaustion and heat stroke.

An Ozone Action Day Alert is also still in effect for the Denver Metro area Thursday as smoky weather continues.

Ozone concentrations are expected to reach the unhealthy for sensitive groups level Thursday during the afternoons and evenings. Although the high level of ozone concentrations are possible throughout the northern Front Range on Wednesday, they
should be more limited to areas in and near the Denver metro area Thursday.

Additional air pollution in the region may directly worsen air quality or contribute to precursors which may also adversely affect air quality.

The smoky weather will also make visibility poor again Thursday.

In Denver, isolated showers and storms are possible after 5 p.m. and could bring some strong wind gusts to the metro area.

After that, on Friday, a major cooldown will keep Denver temperatures below 70 degrees, and Saturday will be even cooler.
