Hail Events in the Front Range of the Rockies

Severe thunderstorms are fascinating, but can cause great damage, especially when large hail is produced by the storm. Hail is extremely prevalent in the Front Range of the Rocky Mountains, particularly in Colorado and the immediate vicinity. Although hail is frequently produced in non-severe thunderstorms across the country, it has been noted that the highest frequency of significant hail events occur along the Front Range, specifically in Colorado. The reason for the unusually high occurrence of hail isnít directly known. Hail events producing hailstones with a minimum diameter will be collected via Severe Plot. Information about storm location, the topography of the environment, and meteorological parameters such as Convective Available Potential Energy (CAPE), Lifting Condensation Level (LCL) will be studied from these hail events. Statistics will be used to determine whether various parameters are significant in the unusually high frequency of large hail events along the Front Range.
