As hail season approaches in Colorado, it’s essential to understand this fascinating yet potentially destructive weather phenomenon. Hailstorms can cause significant damage to property, vehicles, and even pose risks to people and animals. In this blog, we’ll explore what hail is, how it forms, how it falls, and its potential impact. We’ll also answer some frequently asked questions about hail and provide tips on how to protect yourself and your property.
What is Hail?
Hail is a form of precipitation made of solid ice that forms inside thunderstorm updrafts. Unlike snow or sleet, hailstones are solid chunks of ice that can vary in size, from tiny pellets to golf ball-sized or even larger. Hail can cause severe damage to homes, vehicles, and aircraft, and it can be deadly to livestock and people.
How Does Hail Form?
Hailstones form when raindrops are carried upward by strong thunderstorm updrafts into extremely cold areas of the atmosphere. At these high altitudes, the temperature can drop below -40°F, causing the water droplets to freeze into ice.
Once frozen, hailstones grow by colliding with supercooled liquid water droplets that freeze upon contact. The process can create layers of clear and cloudy ice, depending on how quickly the water freezes:
- Cloudy Ice: Forms when water freezes instantly, trapping air bubbles.
- Clear Ice: Forms when water freezes slowly, allowing air bubbles to escape.
Hailstones continue to grow as they are carried up and down within the thunderstorm by the updraft. Eventually, when the hailstone becomes too heavy for the updraft to support, it falls to the ground.
How Does Hail Fall to the Ground?
Hail falls when it becomes heavy enough to overcome the strength of the thunderstorm’s updraft. Gravity pulls the hailstone toward the ground, but its path can be influenced by local wind conditions:
- Smaller Hailstones: These can be blown away from the updraft by horizontal winds, causing them to fall farther from the storm’s center.
- Larger Hailstones: These typically fall closer to the updraft because they are less affected by horizontal winds.
In some cases, strong surface winds can cause hail to fall at an angle or even nearly sideways. Wind-driven hail can cause extensive damage, tearing up siding on houses, breaking windows, and even injuring people and animals.
How Fast Does Hail Fall?
The speed at which hail falls depends on its size, shape, and the degree of melting as it descends. Early research assumed that hailstones fell like solid ice spheres, but recent studies have shown that natural hailstones fall more slowly due to their irregular shapes and air friction.
For small hailstones (less than 1 inch in diameter), fall speeds are relatively low. However, larger hailstones can reach speeds of up to 100 mph, making them capable of causing severe damage to property and injuries to people and animals.
The Impact of Hail
Hailstorms can cause significant damage, especially in areas like Colorado, where hail is common during the spring and summer months. Some of the most common impacts include:
- Property Damage: Hail can break windows, damage roofs, and tear siding off houses.
- Vehicle Damage: Hail can dent car exteriors, break windshields, and cause other costly repairs.
- Agricultural Damage: Hail can destroy crops, leading to significant financial losses for farmers.
- Injury and Fatalities: Large hailstones can cause severe injuries or even death to people and animals caught outside during a storm.

FAQs About Hail
1. What is the largest hailstone ever recorded?
The largest hailstone ever recorded in the United States fell in Vivian, South Dakota, in 2010. It measured 8 inches in diameter and weighed nearly 2 pounds.
2. When is hail season in Colorado?
Hail season in Colorado typically runs from April through September, with the peak occurring in May and June.
3. How can I protect my property from hail damage?
- Install impact-resistant roofing materials.
- Park vehicles in a garage or under a carport during storms.
- Use hail-resistant window coverings or shutters.
4. Can hailstorms be predicted?
Meteorologists can predict the likelihood of hailstorms by analyzing weather patterns, but the exact size and location of hailstones are difficult to forecast.
5. Why does Colorado experience so much hail?
Colorado’s high elevation and frequent thunderstorms create ideal conditions for hail formation. The cold air at high altitudes allows hailstones to form and grow before falling to the ground.
