Denver started Saturday, July 25, on a deceptively pleasant note, with clear skies and a mild morning reading of about 73°F at the KBJC observation. That comfortable start will be short-lived. Forecasters expect highs to rocket into the upper 90s on Saturday and flirt with 100°F on Sunday, July 26, with warm nights offering little relief. While scattered afternoon and evening storms are on the table, most neighborhoods will be battling the heat more than the rain, and outdoor plans could quickly turn from fun to risky.
Heat Advisory And Storm Chances
The National Weather Service has issued a Heat Advisory for the I-25 corridor and the Denver metro from 11 a.m. to 9 p.m. MDT on both Saturday, July 25, and Sunday, July 26, according to the National Weather Service. Daytime highs are expected to climb into the upper 90s to around 100°F, and the forecast discussion notes that local records could be tied or even broken if the hottest numbers verify.
Each afternoon, there is a modest shot at showers and thunderstorms, most likely after midday near the foothills and along I-25. These storms should be hit-and-run events, but they can still pack a punch with gusty outflow winds and brief, heavy downpours. Early next week, the pattern shifts as monsoonal moisture returns, raising the chances for slower, deeper storms and locally heavier rain.
Where To Cool Off
To help residents ride out the heat, the City is opening recreation centers and libraries as daytime cooling sites while the advisory is in place. A current list of locations and hours is available from Denver7. Anyone without reliable air conditioning is urged to plan a visit to a cooling site, carry water, and avoid strenuous work from late morning through early evening. Officials also remind residents to check on neighbors and pets, and to never leave children or animals unattended in a parked car.
