Castle Rock hail storm history
Douglas County·NOAA NCEI Storm Events Database·~75-day publication lag
Castle Rock sits in Douglas County on Colorado's Front Range, where afternoon thunderstorms tracking northeast from the Rocky Mountains create regular hail risk during spring and early summer. The city's elevated terrain and proximity to mountain moisture convergence zones make it a corridor for convective hail events that can produce significant damage to residential property.

Most significant storms occur in the afternoon hours between 2 p.m. and 7 p.m. Mountain Time, when solar heating and upper-level wind shear align to fuel supercell development. Winter months see minimal hail activity, and fall events are rare.
