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

Lone Tree is located in Douglas County on the Front Range corridor, where afternoon convective storms tracking northeast from the Rocky Mountains create regular hail risk during spring and early summer. The city's elevation and proximity to mountain weather systems expose it to significant hail events that can affect residential roofs and property across the community.

Type of damage

How urgent?

Hail risk in Lone Tree peaks from May through July, with secondary activity occurring in April and August. Most significant events develop between 2 p.m. and 7 p.m. Mountain Time, when afternoon heating destabilizes the atmosphere and storms move northeast off the high country. This seasonal window concentrates the majority of damaging hail activity into a predictable summer period.
