This is a brief explanation as to what happens to create some of the weather events that we encounter. This will help you understand what to look for when the threat of a storm is in our targeted areas. As well as what sizes and situations to watch out for.
Hail is caused by strong thunderstorms with intense updrafts, high moisture content, and a freezing layer in the atmosphere. Here’s how it forms:
-
Strong updrafts in a thunderstorm carry raindrops upward into extremely cold areas of the atmosphere.
-
In these upper parts of the storm cloud (cumulonimbus), the temperatures are below freezing, so the raindrops freeze into small ice pellets.
-
These ice pellets are kept aloft by the updrafts and collect more layers of supercooled water (liquid water below freezing temperature).
-
As the pellets are repeatedly lifted and dropped within the cloud, they gain more layers of ice and grow larger.
-
Once the hailstones become too heavy for the updraft to support, they fall to the ground as hail.
- Damage can very based on the size of the hail and wind speeds.
The stronger the updraft, the larger the hail can grow before falling.
Hail is classified by most experts by a standing size comparison.
1/4″ = Pea Size
1/2″ = Mothball Size
3/4″ = Penny Size
1″ = Quarter Size
1.5″ = Ping Pong Ball Size
1.75″ = Golf Ball Size
2″ = Chicken Egg Size
2.5″ = Tennis Ball Size
2.75″ = Baseball Size
3″ = Large Apple Size
4″ = Baseball Size
4.5″ = Grapefruit Size
4.75″-5″ = CD/DVD Size
The size of hail determines the damage done to homes but can also have a higher affect with high wind speeds (60 MPH or greater)
