Denver is starting Sunday clear and calm near 66 degrees, but the easy morning will give way to another hot afternoon and a round of thunderstorms. Highs should reach about 93 degrees before temperatures slide into the mid-80s as storms move across the area.

Storm Chances Rise After 2 P.M.

Mostly sunny skies are expected through the first part of the day, with showers and thunderstorms becoming more likely after 2 p.m. The National Weather Service Denver/Boulder office puts the overall rain chance at 40%, with brief heavy downpours possible from the stronger cells.

A few storms across the plains could become severe, producing isolated damaging wind gusts and hail. The greatest concern is expected east of the Denver urban corridor, but metro-area residents should still be ready for quickly shifting winds and a sudden temperature drop. No watches, warnings, or advisories are currently posted, according to the National Weather Service.

Stormy Pattern Lingers Into Midweek

Monday looks much like Sunday, with mostly sunny skies, a high near 92 degrees, and another 40% chance of afternoon and evening thunderstorms beginning after 4 p.m. Tuesday and Wednesday turn slightly cooler, with highs near 89 and 88 degrees, but both days still carry afternoon storm chances.

The unsettled stretch follows several recent rounds of Denver-area heat and thunderstorms, including earlier Hoodline coverage of the region's storm cycle. For outdoor plans, Sunday morning and early afternoon offer the clearest window; keep an eye on the sky later in the day and bring in lightweight patio items before winds pick up.

Hotter And Drier By The Weekend

Storm chances ease Thursday, when Denver is forecast to reach about 91 degrees with only a slight chance of an afternoon thunderstorm. Friday and Saturday rebound to highs near 93, with mostly sunny skies and lower rain chances — a warmer, drier finish after the midweek storm threat.
