Hail is solid precipitation in the form of balls or pieces of ice known as hailstones.
How does hail form? Hail forms in thundercloud when drops of water are continuously taken up and down though the cloud by updraughts and downdraughts. When they go to the top of the cloud, it is very cold and they freeze. As the updraughts in thunderclouds are very big, they can keep
is actually buried in hail. A key factor in this event was the local topography. Ottery is situated by the River Otter which is aligned north-south. This moist southerly flow fed into the existing storm and was forced to rise over Woodbury Common. Reports suggest that the size of the hailstones

When we talk about precipitation, we are talking about water that is falling out of the sky, this could be rain, drizzle, snow, sleet, hail or something rarer! But most of the time in the UK it's rain, so if you hear someone using the word 'precipitation' it probably means that the weather is going
, they are propelled towards the top of the cloud by strong internal winds (updraughts) where they turn to ice. Some of the pieces of ice grow into hail, but others remain very small. Some of the hail that forms becomes too heavy to be propelled by the updraughts and so begin to fall back through the cloud
in the south reaching double figures whilst some parts of Scotland struggle to get above 5 °C or so. Saturday will see sunny intervals and showers, these wintry in the north, whilst in the south they could be heavy with the chance of thunder and hail. There is also the possibility of more prolonged
of air and they fall as hail. As hail moves within the cloud, it picks up a negative charge by rubbing against smaller positively charged ice crystals. A negative charge forms at the base of the cloud where the hail collects, while the lighter ice crystals remain near the top of the cloud and create
How does lightning form? As tiny water droplets form inside a storm cloud, they are propelled towards the top of the cloud by strong internal winds (updraughts) where they turn to ice. Some of the pieces of ice grow into hail, but others remain very small. Some of the hail that forms becomes too
in some other areas, also turning heavy and thundery in places with hail, and snow over hills, the maximum at Blencathra (Cumbria) struggling to 5.7 °C. The 5th started chilly, mostly sunny and dry, though showers in western areas soon spread eastwards to cover most parts, some of them wintry
