Hail Alley – that is the nickname some have given to Colorado’s front range where the great plains of the American west rush into the Rocky Mountains. “Hail Alley” actually stretches from the state of Wyoming down to Texas and covers parts of Kansas, Nebraska, and Oklahoma. Some researchers may include areas of Illinois, Iowa, and Missouri.
Thunderstorms are the main cause of trouble. Severe weather can create damaging hailstones that are over one–inch in diameter. Since Colorado is in hail alley we can usually expect 7-to–9 hailstorms a year. The type of hail that will damage your home (1.0 inch to 1.75+ inch in diameter) could slam into your roof at 25 to 40 MPH.
FYI:
the biggest hailstone ever recorded in Colorado was 4.83 inches in diameter. It fell in Yuma County, Colorado on August 8, 2023.
