Grand Junction, Colo. – Drivers across western Colorado should brace for late-day thunderstorms that could drop hail and bring dangerous travel conditions. Commuters on Interstate 70 and Highway 50 could face slick pavement and reduced visibility as storms roll through the valleys and nearby ranges.
According to the National Weather Service in Grand Junction, widespread showers and thunderstorms will develop Tuesday afternoon and evening, favoring the northern and central mountains before drifting toward the lower valleys. Gusty winds may exceed 40 mph, and brief heavy rainfall could create ponding on roads. Hail remains possible in the stronger cells.
Communities from Glenwood Springs to Montrose should expect scattered delays, particularly near mountain passes. Outdoor events face the risk of lightning, making caution essential for hikers and late-day travelers. Officials urge drivers to slow down, keep headlights on, and avoid flooded intersections.
Conditions will settle by Wednesday, with mostly sunny skies returning and highs near 86 degrees. Isolated storms may linger along the Divide into midweek, though coverage will be less widespread. Dry weather dominates later this week before another round of light showers arrives Saturday.
Storm activity remains a hallmark of Colorado’s transition into fall, with rapid changes in weather across mountain corridors. Residents should stay weather-aware and monitor NWS updates, as additional advisories could be issued if storm intensity increases.
