Grand Junction, Colorado – A sizzling weekend is on tap across western Colorado as a stretch of triple-digit temperatures grips Grand Junction and surrounding areas through early next week.
According to the National Weather Service in Grand Junction, widespread haze will return Saturday afternoon as highs climb to 99°F. Sunday and Monday will likely reach 100°F, with light but shifting winds increasing fire danger across Mesa County. The heat is expected to linger through Tuesday, July 2.
Residents are urged to avoid prolonged outdoor exposure between 2 and 6 p.m., when UV levels and ozone concentration peak. Vulnerable groups — including the elderly, outdoor workers, and pets — should take extra precautions. Keep cool by staying indoors, hydrating frequently, and limiting strenuous activity. The hot, dry conditions could also affect visibility and air quality along U.S. Highway 50, especially during the afternoon haze.
This marks Grand Junction’s first run of 100°F days this summer, a full week ahead of Independence Day. While no storms are forecast this weekend, a slight chance of thunderstorms returns Tuesday night, offering potential relief but also sparking wildfire concerns.
More updates are expected Monday as conditions evolve. Heat advisories may be issued if temperatures climb further.
