Dangerous Weekend Heat Building Into the 90s to Near 100 Degrees Across Colorado Including Denver Front Range Western Slope and Eastern Plains Saturday and Sunday
COLORADO AND SURROUNDING REGION — A strengthening ridge of high pressure is building across the western United States Friday June 5th, sending temperatures surging through the weekend with Saturday and Sunday shaping up as the hottest days of the stretch. The western slope will see valley temperatures well into the 90s with a few lower desert locations potentially flirting with 100 degrees.
Along the Front Range, I-25 corridor, and lower foothills, temperatures will climb into the 90s this weekend with a few locations potentially challenging record highs.
Western Slope Roasts Into the 90s With Desert Locations Approaching 100 Degrees
The western slope enters the hottest stretch of the year so far this weekend, with valley locations running well into the 90s under hot, dry, and breezy conditions. A few lower desert communities could approach 100 degrees by Saturday and Sunday as the ridge amplifies overhead.
Friday alone brings western slope valley highs into the 90s, with conditions described as hot, dry, and breezy. Fire danger is elevated and will increase further through the weekend across this zone.
Front Range Hits Mid 80s to Low 90s Friday Before Near-Record Heat Arrives
The Foothills and Front Range I-25 corridor reach the mid 80s to low 90s Friday, warm to hot conditions that are just a preview of what arrives through the weekend. Saturday and Sunday bring mid 90s possible across many lower elevations with near-record heat possible at some locations.
Humidity remains low across the region, keeping conditions as a dry heat rather than an oppressive humid heat, but prolonged exposure during peak afternoon hours still poses serious health risks.
Eastern Plains Reach Upper 80s to Mid 90s Friday With Widespread 90s and Upper 90s Sunday
The eastern plains into western Nebraska and western Kansas reach upper 80s to mid 90s Friday with isolated storm chances. By Sunday, widespread 90s are expected across the plains with a few upper 90s possible as the heat peaks for the stretch.
Residents across all zones are urged to stay hydrated, never leave children or pets in vehicles, and limit outdoor activity during peak afternoon hours this weekend. Stay with NapervilleLocal.com for the latest weather updates and local forecast coverage.
