Hailstones

This morning the weather was 'reasonable' but its become colder, wetter and darker during the afternoon. I was doing the outside jobs and chasing a robin with the camera when these hailstones looked a possible blip.

From the internet:
Hail is a form of solid precipitation. It consists of balls or irregular lumps of ice, each of which is called a hailstone, hailstones consist mostly of water ice and measure between 5 millimetres and 15 centimetres in diameter. Hail is possible within most thunderstorms as it is produced by cumulonimbi and within a few miles of the parent storm. Hail formation requires environments of strong, upward motion of air with the parent thunderstorm (similar to tornadoes) and lowered heights of the freezing level.
