Denver, Colorado – Sunshine and rising temperatures will return to much of Colorado on Tuesday, with highs approaching 99°F in Denver and across the northeast plains, while scattered thunderstorms could bring afternoon and evening disruptions.
According to the National Weather Service in Boulder, the day will start clear, but scattered storms are likely to develop in the Front Range mountains after noon, spreading eastward by late afternoon. Forecasters warn of a chance for lightning, gusty winds, and brief downpours, especially for communities along I-25, including Fort Collins, Loveland, and Boulder.
In Denver, afternoon temperatures will climb rapidly into the upper 90s, with heat indices possibly exceeding 100°F. Cities like Sterling, Akron, and Burlington are also expected to reach the high 90s. Travelers should be alert for sudden storm development, especially on US-36, I-70, and rural roads across Weld and Morgan counties.
Residents are urged to limit outdoor activities during peak heat, stay hydrated, and monitor for updated storm alerts if planning travel late in the day. If thunder roars, move indoors promptly to avoid lightning danger.
Scattered storm chances remain into Tuesday night, especially for the northeast plains. More advisories may be issued if conditions worsen.
