Adams County·NOAA NCEI Storm Events Database·~75-day publication lag
Commerce City, located in Adams County, has recorded zero hail events of 1 inch or larger over the past 10 years according to available NOAA data. The city sits on the Front Range of Colorado, a geography that can channel afternoon convective storms tracking northeast from the Rocky Mountains, though Commerce City itself remains in a zone with lower historical hail frequency than areas directly along the foothills.
When hail does occur in the Commerce City area, it is most likely between May and July, with secondary risk in April and August. Storms typically develop in the afternoon, between 2 p.m. and 7 p.m. Mountain Time, as warm air rises from the plains and collides with moisture-laden air moving northeast from the mountains.

No hail events recorded in the NOAA Storm Events Database for Adams County.
This may reflect limited spotter coverage, not absence of hail activity.
NOAA maintains lower reporting density for Adams County compared to other Colorado Front Range counties, which may mean smaller hail events are underrepresented in the historical record. Homeowners in Commerce City should not assume that the zero recorded 1-inch events reflects complete absence of hail risk, particularly during the May through July peak season.
