Hailstones fall in London as Arctic blast sends temperatures tumbling [Video]

Hail fell in London on Thursday afternoon as an Arctic blast sent temperatures plummeting across the UK.

One Londoner captured video showing hailstones falling outside their window in Osterley, Hounslow, on Wednesday afternoon.

Elsewhere, social media users reported the weather changing between “warm sunshine, major hail [and] warm sunshine” in the space of an hour.

The Met Office predicted possible lows of 6C in London overnight on Wednesday, and daytime highs of just 15C on Thursday.

The forecaster said the temperature would fall to 6C again in the early hours of Friday, which was set to be another cold but sunny day with highs of 17C.
