The Met Office has issued a rare ‘thundersnow’ warning today, which is set to impact parts of Northern Ireland.
There is also a chance of thundersnow in west Wales, and the east and south-west of England.

The unusual phenomenon occurs when the atmosphere is turbulent enough to form cumulonimbus clouds and typically happens around 10 times a year worldwide.
