Jefferson County·NOAA NCEI Storm Events Database·~75-day publication lag
Arvada, located in Jefferson County on Colorado's Front Range, sits in a corridor where afternoon convective storms tracking northeast from the Rocky Mountains create recurring hail risk. The city's elevation and position along the foothills make it susceptible to the atmospheric conditions that produce hailstorms during the warm season.
