Grand Junction, Colo. – Scattered thunderstorms are expected to fire up across western Colorado this afternoon, especially over high terrain, bringing gusty winds and lightning threats through the evening hours.
According to the National Weather Service in Grand Junction, a weak disturbance is sliding down the Continental Divide, sparking increased storm activity compared to Tuesday. Most showers will target the mountains, but a few could drift into lower valleys, including areas near Montrose and Delta, later in the day.
The biggest risks include strong, erratic wind gusts and frequent lightning strikes, particularly in the afternoon and early evening. Drivers on I-70 through Glenwood Canyon and U.S. 550 near Ouray should be alert for rapidly changing conditions. Outdoor recreation in higher elevations could also be disrupted.
Daytime temperatures will stay well above average, with parts of the Western Slope flirting with the 90s by the weekend. Residents are encouraged to secure loose outdoor items and delay high-elevation hikes until storms clear.
Storm chances taper off by late tonight, but warm, summer-like conditions will return into the weekend. Another round of mountain storms is possible by early next week.
