Freak weather conditions led to parts of Huddersfield being bombarded with hailstones.
The hailstones then turned to snow causing chaos on some roads late Saturday afternoon and into the evening – including the M62.
Two weather fronts had clashed to cause the problem.
Huddersfield weather expert Paul Stevens said a dry and cold north-easterly wind had run into a north westerly wind which had more moisture in it over parts of Kirklees.
This result meant the air was forced upwards with hailstones being formed high in the atmosphere at around 30,000ft.
Paul said: “They were very dry when they fell which means they were exceptionally cold from being formed so high up in temperatures as low as about -30˚C. It was a spectacular hailstorm complete with thunder and lightning but very localised.
"While some places really suffered from the hailstones and then snow there was nothing at all in other parts of Huddersfield. Within around a quarter-of-a-mile you could go from green fields to blizzard conditions.”
The area near to where Paul lives in Salendine Nook was particularly hard hit with traffic forced down to 30mph for a while on the M62 and New High Road at Outlane became iced up, causing traffic tailbacks.
Round Ings Road up to Scapegoat Hill – a notorious accident blackspot especially in bad weather – became gridlocked for a while after a car skidded off the road and ploughed into a wall. No-one was hurt. A Land Rover was used to pull some of the cars up the steep hill.
Some of the hailstones were measured at 0.5cms.
Temperatures had plummeted to -2˚C on Saturday night making it one of the coldest nights of the winter.
The cold front is due to drift south tomorrow and then things will settle down as high pressure takes over ... but only for a few days.
Paul said: “In the sun it will feel warmer but there will be some chilly nights up to around Thursday. But as we head towards next weekend the high pressure drifts towards Greenland so we will have some unusually cold air coming towards us with some night frosts and even the risk of snow showers down to low levels.
“There’s no sign of a spring let-up in the weather yet.”
