Denver is starting Wednesday, August 26, with clear skies and temperatures in the low 60s, but the quiet morning is not the whole story. The city should warm into the upper 80s before showers and thunderstorms become possible after 3 p.m., setting up a day of sunshine, heat, and a potentially noisy evening.

Storms Could Bring Hail And Strong Winds

The National Weather Service Denver/Boulder office says scattered afternoon and evening storms are expected across the I-25 corridor and nearby plains. A few could turn severe, with hail and strong outflow winds; areas south of Interstate 76 face a better chance of storms producing hail up to 1.5 inches and gusts of 60 to 65 mph.

Storm chances rise from about 3 p.m. through the early evening, when temperatures should ease from the mid-80s. The strongest storms could bring brief heavy rain and an isolated flooding risk, while storm activity is expected to move out of the area by around 10 or 11 p.m.

Thursday Warms Up Before Weekend Heat

Thursday looks mostly sunny with a high near 90 and only a slight chance of a late-day shower or thunderstorm. Friday and Saturday are forecast to reach about 95 degrees, with mostly sunny skies Friday and a chance of afternoon storms returning Saturday.

Sunday brings the best rain chance in the extended forecast, with showers and thunderstorms likely after noon and a high near 89. Monday stays warm near 88 with another afternoon storm chance, while Tuesday rebounds toward 90.

What To Know Before Heading Out

Outdoor plans should be easiest this morning and around midday, before storm chances build. If thunder develops, move indoors; during the strongest cells, be ready for sudden wind, hail, and brief heavy rain, especially across the I-25 corridor and plains.
