Grand Junction, CO – Intense July heat grips western Colorado Sunday as Grand Junction braces for a string of triple-digit days starting today.
According to the National Weather Service in Grand Junction, temperatures will soar to 98°F Sunday, then rise steadily, peaking near 103°F by Wednesday. A high-pressure ridge will dominate the region, keeping skies mostly clear and rain chances low through Thursday.
Mesa County residents, especially those traveling along I-70, should prepare for heat-related impacts including vehicle overheating, dehydration, and increased wildfire risk. Limit outdoor activity to early morning or late evening hours, and make sure pets and livestock have access to shade and water.
