The William Hill Lincoln meeting at Doncaster Racecourse, which heralds the start of the flat racing season, has been abandoned today because of snow. Up to three inches of snow has fallen on the track overnight. The meeting has been rescheduled for next Saturday.
Wide-spread disruption across the UK, due to snow and flooding, has led forecasters to predict this month will be the coldest March in 50 years.
John Lee, forecaster with MeteoGroup, the weather division of the Press Association, said the average temperature expected for central England at this time of year is 6C (42.8F), but so far this month the average is 2.2 degrees below that - at 3.8C (38.8F).
That is significantly colder than last March, when averages were 8.3C (46.9F) - 2.3 degrees above the expected average.
"Comparing it to similar winters, it's provisionally going to be the coldest March in 50 years, although that can't be confirmed until we reach the end of the month," Mr Lee said.
He referred to 1962 - when average temperatures were even colder, at 2.8C (37F), adding: "That will take some beating.
"But the way we are going it looks like we are heading towards being the coldest March since then."
More snow is forecast for many areas, he said, but gradually, by the end of Saturday and the end of Sunday, it will be mostly dry.
More snow and biting winds will again hit parts of northern England today, continuing a bleak week for Britain.
North-east England will see scattered snow storms throughout the day add a further five centimetres of the white stuff in higher ground and up to two cms in lower ground.
Coastal areas across England, Wales and Scotland will feel the worst of bitterly cold winds of up to 50mph, which will force temperatures down by around eight degrees.
The worst of the snow storms will hit the north-east of England from Northumberland down to Norfolk, and will be heavier over higher ground in places like the North Yorkshire Moors and Lincolnshire Wolds.
Heavy snow brought traffic chaos to parts of South Yorkshire and North Derbyshire this morning with many roads around Sheffield gridlocked during rush hour. Scores of bus services were cancelled, trains were delayed and ten schools were closed. David Hirst reports.
Snow is making driving conditions more difficult in North Yorkshire this afternoon. This was the A169 between Pickering and Whitby.
Buses heading for Whitby are also terminating at Thornton-le-Dale, because the road is blocked by snow.
Drivers and commuters had a difficult journey to work in South Yorkshire and north Derbyshire this morning as several inches came down in the early hours, affecting rush hour. Lincolnshire and other parts of Yorkshire were also hit with lighter snow showers. Here's a round up from across the region
26 gritters as well as tractor ploughs, JCBs and other vehicles are out trying to clear the roads of snow in Sheffield.
Our operations are continuing and will do so until the snow is clear. Roads will be cleared in priority order. We are also doing all that we can to keep the pavements clear. We have been clearing snow from pavements on key city centre routes, around hospitals and around key shopping centres. This work has been ongoing since early morning and we have around 300 staff involved in this.
Lincolnshire Police say they've dealt with around 25 road traffic collisions overnight as a result of the bad weather. Officers say there have been 15 incidents since 7am this morning, although there have been no serious injuries. There have been fewer incidents in the south of the county.
