About Tornadoes in Greeley

This overview was written July 29, 2026. The tornado counts and notable-event figures elsewhere on this page reflect the latest data and may differ from this summary.

Greeley sits on the high plains of Weld County, east of Colorado's Front Range, where spring and summer moisture pushing upslope into converging plains winds makes tornadoes a familiar part of the warm season, with activity clustering from May through July.

Some of those days have turned destructive. On May 22, 2008, an EF3 tornado tore a 38.69-mile path up to 1,760 yards wide through the area, killing one person, injuring 78, and causing $147 million in property damage. Decades earlier, an F3 struck on May 15, 1952, carving a 7.4-mile track and injuring five people, and an F2 on June 10, 1990 stayed on the ground for 23 miles. Strong tornadoes have appeared in recent years as well: an EF3 on June 5, 2015 cut a 6.71-mile path up to 440 yards wide, and an EF2 on June 7, 2021 tracked 7.5 miles and caused $530,500 in property damage.

Just as characteristic of Weld County are days when weaker tornadoes touch down in bunches — June 4, 1976 brought a string of them, including F2s, and EF0 tornadoes dropped repeatedly across the area on May 21, 2020. Nor is the season rigid: an EF0 touched down on March 23, 2019, and F1 tornadoes struck on October 4, 2004.
