Denver is starting Saturday, August 8, with clear skies and temperatures in the upper 60s, but that pleasant morning is only a brief prelude to a triple-digit afternoon. A Heat Advisory will cover the metro as the city heads toward 101°F, with smoke lingering overhead and only a slim chance of a shower.
Smoke Hangs Around As Temperatures Surge
The advisory runs from 11 a.m. Saturday, August 8, through 8 p.m. Sunday, August 9, for Denver, the western suburbs, Boulder and other parts of the Urban Corridor. The National Weather Service says temperatures could range from 98 to 102°F, a stretch that may cause heat illness. Saturday will be mostly sunny, though readings may ease into the upper 90s late in the afternoon.
Smoke is expected across Denver before 2 p.m., then a slight chance of rain showers arrives during the afternoon. The chance of measurable rain is just 20%, and the very dry air could cause some showers to evaporate before reaching the ground. Outdoor plans near the foothills and higher terrain could also encounter gusty outflow winds.
Sunday Stays Hot Before The Pattern Shifts
Saturday night stays warm, with a low near 69°F and smoke still possible. Sunday, August 9, brings another mostly sunny day with a high near 99°F, smoke before noon and a 20% chance of afternoon showers or thunderstorms, with gusts up to 18 mph. Drink water, take breaks in shade or air conditioning, and move strenuous activities to early morning or evening.
Cooler, Stormier Weather Arrives Later
Monday, August 10, and Tuesday, August 11, remain hot near 97°F with slight afternoon chances for showers and thunderstorms. Wednesday, August 12, cools to around 91°F as storm chances increase, with thunderstorms likely Wednesday night. By Thursday, August 13, and Friday, August 14, highs fall to around 80°F and 77°F, while showers and thunderstorms become much more likely.
For Denver residents, the weekend forecast is a reminder that the early-morning air can be deceptive: comfortable conditions give way to dangerous heat within hours. The most substantial relief arrives late next week, when clouds, rain chances and cooler temperatures finally push the triple-digit stretch out of the spotlight.
