Late July 2026 saw a persistent extreme‑heat event across Colorado and Wyoming. On July 24, the National Weather Service warned of triple‑digit temperatures in Kiowa County, Colorado, with highs near 103 °F, and issued a severe‑weather outlook for Cheyenne, Wyoming, highlighting isolated tornadoes, large hail and damaging winds. Two days later, the heat wave continued, with Cheyenne Wells, Colorado, also expected to hit 103 °F and southeast Wyoming experiencing 100‑plus‑degree conditions across the High Plains. Heat advisories remained in effect, but forecasters anticipated a brief cooling as thunderstorms and monsoon moisture moved in, bringing rain chances that rose through the week. Residents were repeatedly advised to stay weather‑aware for both heat‑related health risks and the lingering threat of severe storms.
