Hail is solid precipitation that forms when raindrops are carried upward by thunderstorm updrafts. When these drops move into extremely cold areas of the upper atmosphere, the water freezes. As these pellets move around they collide with liquid water drops that coat the pellets and freeze, and this can continue to happen until the weight of the pellet becomes too great to be supported by the thunderstorm’s updraft. Many coats of frozen layers can exist on one pellet, and of course the more layers, the larger the hailstone.
Wind-driven hail can be especially damaging – instead of falling straight down, it can pound the sides of buildings and break windows. Cars frequently are on the losing end of the battle with hail. Crops (and basically all plants) are susceptible to hail damage. In July of 2023, hundreds of birds were killed and/or injured in Oklahoma City by hail.
Oklahoma tends to get more hail than most states. Peak hail season is mid-April through mid-May, and hail has made the news this year in many locations and during many storms. In recent history, hail has not taken many lives, although a large enough hailstone bonking a person right on the noggin can do the trick. While not common, cattle and chickens can be killed by hail. The pellets are damaging, and the noise and confusion caused by severe storms can increase animal stress levels.
Thunderstorms can happen without hail, but hail happens with thunderstorms. To be safe, be weather aware. By cell phone, computer, radio, or television, keep tabs on the weather. Try NOT to be out and about in severe weather, and if you are, go to a place where you can take cover. Go to a saferoom, storm shelter, or most interior room of a dwelling. Do not be tempted to run out into a hail storm to pick up especially large or interesting hailstones. Snag these after the storm has passed. They will keep a long time in the freezer.
The largest hailstone on record is about the size of a bowling ball. Typically hail is no larger than a golf ball, which can still bruise flesh or slice the thin skin of a scalp.
Cheryl Cheadle Volunteer Coordinator
  Friends of Blue Thumb – The Friends of Blue Thumb (FBT) Board has room for three new members. If you have been through Blue Thumb training for new volunteers, please consider serving on the Board. When this nonprofit organization formed circa 2010, the goal was to protect wadeable streams by supporting the Blue Thumb volunteers who were stream monitors.
It isn’t easy for a state program supported by federal dollars to readily provide money for the volunteers. That gap left a place for FBT. Some of the ways volunteers have benefitted include:
- Purchases of waders and winter gloves
- Funds to help volunteers attend conferences and training sessions
- Exhibits to get information out to the public
- Help to cover education signage
When FBT first became an organization, Oklahoma’s conservation districts joined at a special rate of $75, when the lifetime membership fee was (and still is) $150. Many districts joined in the early days, with more coming aboard over the years. These conservation districts have turned to FBT for funds to help with local tours, natural resource days for children, educational tools, and more.
Since 2020, the birth year of the Yard by Yard Community Resiliency Project, FBT has been a big player in this project’s support by providing funds for signage and seed. Yard by Yard continues to grow throughout Oklahoma.
Friends of Blue Thumb has maintained an active Board since the beginning and has many new members. There is room for three additional Board members. We meet primarily by ZOOM every other month but will meet in person in OKC on July 16 at our summer retreat. If you want to learn more about what it means to be a member of the FBT board, contact the chairwoman Terrie Becerra.
Friends of Blue Thumb is accepting mini-grant proposals from active Blue Thumb volunteers and member conservation districts throughout June. You may complete the short application here. Please contact Cheryl if you have questions about mini-grants.

The North American Paddlefish is an aquatic 'living fossil' that has been around since the age of dinosaurs. This is a cartilaginous fish with a unique paddle-like snout, or rostrum, covered with electroreceptors that allow for adult paddlefish to detect and filter feed on zooplankton floating in the water column. In Oklahoma, paddlefish exist in various parts of the Arkansas and Red river basins, and successful conservation efforts have secured self-sustaining populations in many parts of their range.
This fish is considered a living fossil because fossil records of paddlefish date back to ~300 million years ago, meaning this fish’s ancestors survived the Great Dying which was the most severe extinction event in Earth’s history! The American paddlefish is the sole survivor of this group; its only other modern cousin, the Chinese Paddlefish, was declared extinct in 2020.
