Littleton hail storm history
Arapahoe County·NOAA NCEI Storm Events Database·~75-day publication lag
Littleton, located in Arapahoe County, has recorded zero hail events of 1 inch or larger in the past 10 years according to NOAA data. The city's position on the Colorado Front Range exposes it to afternoon convective storms that track northeast from the Rocky Mountains, creating conditions where hail can develop during peak season.
Hail risk in Littleton is highest from May through July, with secondary activity occurring in April and August. Most significant hail events in this region occur between 2pm and 7pm MT, when afternoon heating strengthens thunderstorm development. The specific orientation of the Front Range near Littleton channels these storms in a northeast trajectory that can produce severe weather.

The absence of recorded 1-inch-or-larger events over the past decade may reflect both lower hail frequency in this specific area and incomplete historical capture in available databases.
