Denver, Colorado – Dangerously hot and dry conditions will dominate eastern Colorado through Thursday, with highs in the Denver metro and surrounding plains expected to reach 103°F by midweek.
According to the National Weather Service in Boulder, urban areas along the I-25 corridor—including Denver, Aurora, Fort Collins, and Colorado Springs—will see daily highs between 100°F and 103°F from Tuesday through Thursday. Mountain and valley regions will remain cooler but could experience isolated late-day thunderstorms on Wednesday and Thursday.
The prolonged heat poses risks for heat-related illness, especially for vulnerable populations. Officials advise limiting outdoor activity during peak afternoon hours, staying hydrated, and checking on neighbors without air conditioning.
In the mountains, afternoon lightning and brief downpours may disrupt hikers and outdoor plans, particularly west of the Continental Divide. Campers and travelers should monitor radar and be prepared to seek shelter quickly.
This high-pressure pattern is expected to hold through the end of the week, with no significant cooldown in sight. More heat alerts may be issued if temperatures continue trending upward.
