South Yorkshire residents woke up to a winter wonderland this morning after a blanket of snow fell across the county.
Much of Sheffield including the city centre, Hillsborough, Crosspool, Walkley, Woodseats and Parson Cross were covered.
Rotherham and Barnsley were also affected.
The flurries began at about 6pm and carried on well into the night.
High Storrs resident Graham Dyson, aged 31, said the snow caused chaos on the roads.
He said: “Motorists were just going crazy and the traffic was horrendous.
“The traffic was crawling along at five miles per hour.
“As soon as it starts snowing, everyone forgets how to drive. It was madness.”
Stannington Road and Wood Lane were gridlocked and angry residents said gritters had not been out, despite the snow alert.
More snow is expected today, the MET Office said, as temperatures continue to plunge.
Motorists have been warned to expect icy conditions, particularly in snow-covered areas and on lower ground where rain has fallen.
Despite the snowfall, this year looks set to be the warmest in Sheffield since rcords began, figures from the city’s weather station at Weston Park show.
The average temperature for 2014 to date is 11.1 degrees, the highest for more than 132 years.
It has been estimated 2014 will be the hottest year ever.
In Sheffield the hottest day this year was July 26, when thermometers reached a scorching 27 degrees, and the warmest nights in July were a balmy 16.6 degrees.
The city enjoyed a warm and sunny summer during events like the Tour de France and Tramlines festival, and even some days in December have seen highs of an unseasonably warm 12 degrees.
Alistair McLean, curator of natural science at Museums Sheffield, said: “As it stands this is the warmest year since our records began in 1882.
“If the temperatures for the rest of December are warmer than average then it is going to be a record breaking year.
“The average for December is about five or six degrees and it has been higher - as well as lower - than that this month.”
The warmest year in Sheffield so far was in 2011, when the average temperature was 11 degrees, and before that was 2006 and 1990, when the temperature was 10.9 degrees.
The coldest was in 1892, when the mean temperature was 7.8 degrees.
In 2014 May 17 was the brightest day, with more than 14.3 hours of sunshine, and a parched September was the driest month with just 14.3mm of rain.
It was also the hottest Halloween ever, in line with the national picture, and in October the highest temperature was 18.8 degrees.
Researchers believe man-made climate change is to blame for the country’s highest temperature in 250 years.
Alistair added: “If you look across our data most of the warmest years on record have been in the last 20 years or so.
“I’ll leave it to the experts to say what that means but it does seem to be getting a bit warmer.”
The weather station shares its data with Star readers every month and a final summary of 2014 will be available after January 5.
Data shows the coldest days were in March and January, when temperatures plunged to an icy minus 1.4 degrees.
The wettest day was in August when 26.3mm of rain fell during freak floods but the most rain-soaked month overall was January, when 124.2mm of rain fell.
