Weld County·NOAA NCEI Storm Events Database·~75-day publication lag

Greeley sits in Weld County on Colorado's Front Range, where afternoon convective storms tracking northeast from the Rocky Mountains create a corridor of elevated hail risk. The city's position along this weather pattern means residents face recurring hail events capable of significant property damage.

Type of damage

How urgent?

Hail risk in Greeley peaks from May through July, when afternoon storms between 2 p.m. and 7 p.m. MT are most likely to produce large hail. April and August see secondary risk as spring and late-summer storm systems move through the region. Most significant hail events that cause functional roof damage occur during the May-to-July window.
