Grand Junction, Colo. – Record-breaking heat continues across western Colorado Friday with temperatures soaring into the upper 90s and even triple digits in some valleys, while storm chances rise through the afternoon. The National Weather Service in Grand Junction warns that lightning, gusty winds, and isolated downpours will develop mainly over the higher terrain, including the San Juan Mountains and Continental Divide.
According to forecasters, the San Juans carry the best chance for rainfall, though showers may spill into nearby valleys late Friday. Afternoon highs will push 100 degrees in Grand Junction, Montrose, and Moab, with little relief until evening. The mix of extreme heat and dry ground raises the risk of fire starts from lightning strikes, while sudden downpours could cause slick mountain roads.
Travelers along U.S. 550 and I-70 should watch for reduced visibility, wet pavement, and strong wind gusts near storms. Residents are urged to limit outdoor activity during peak heat, hydrate frequently, and remain indoors during lightning activity.
Conditions begin to shift late Friday night into Saturday as cooler air and broader rain coverage move in, setting up a wetter pattern by Sunday.
