This afternoon's meeting at Fairyhouse has been cancelled after the country awoke to widespread snow and frost while Newbury is the only turf meeting to be given the go-ahead this afternoon.
Heavy snowfalls left the track unraceable yesterday, with a sharp overnight frost meaning the Irish venue was unfit for racing today.
"The combination of the frost and snow has meant the meeting has had to be cancelled," said Irish Turf Club spokesman Cliff Noone.
"However, the meeting is not necessarily abandoned because there could be the possibility Fairyhouse rearrange it for a later date."
Haydock's meeting has been abandoned due to snow, while Kelso were forced to admit defeat early this morning.
Officials at the Scottish venue were left with no alternative other than to call off the seven-race card after overnight temperatures fell to minus-five degrees - with a two-inch layer of snow on the track exacerbating the issue.
"As the week progressed you could see this coming," said Kelso head groundsman Brian Meikle.
"We were fine all week, but it went to minus seven on Thursday night and there was no way the frost was coming out of the ground after that.
At Haydock, clerk of the course Kirkland Tellwright was forced to draw stumps on the seven-race card following an 8am inspection.
Intense snow showers yesterday evening were compounded by overnight temperatures also dipping to minus-five degrees.
"We had a lot of snow between 5.30pm and 6.15pm yesterday and it is too overcast today for the situation to improve," explained Tellwright.
However, the news was far better at Newbury, who passed a 7.30am precautionary inspection and go ahead as scheduled.
Despite overnight temperatures falling to minus-five degrees, officials at the Berkshire venue were able to give the meeting the green light because of the implementation of their innovative course cover.
Clerk of the course Richard Osgood and his team, which included trainer Nicky Henderson, shrouded the entire track in a fleece blanket after racing yesterday afternoon.
And their tireless efforts have had the desired effect as the track, which features the Vodafone Gold Cup, has been passed fit for racing following an early-morning check.
"It has been a great team effort and things are warming up nicely," reported Newbury managing director Mark Kershaw. We are expecting the temperature to rise to around plus-four degrees by midday and plus six by the time we start racing.
"It took around two hours to cover the course and we had help from the likes of Nicky Henderson, Mick Fitzgerald, Hughie Morrison and all the office girls here. This shows that the course-cover idea is workable and we are all obviously delighted."
No anticipated problems are envisaged on the all-weather at Lingfield and Wolverhampton - although the latter's clerk of the course Fergus Cameron is "monitoring the situation" after overnight temperatures dropped to a baltic minus-eight degrees.
"We have no planned inspections but around one centimetre of snow has fallen on the track this morning," said Cameron.
Sunday's fixture list is also in danger of decimation as Huntingdon and Bangor have called afternoon inspections at 1pm and 4pm respectively.
Bangor escaped any further snow showers last night and officials are hoping to see further improvement as the day progresses.
"We initially called a 1pm inspection but moving it back gives us a full day to assess the situation," said Bangor general manager Jeannie Chantler. "We fell to around minus-seven degrees overnight and more frost is forecast tonight. There was no snow last night though which was a plus."
Frost is the main problem at Huntingdon, however, as overnight temperatures fell to minus-five degrees.
"Because of the sun, the frost came out of the ground a lot better yesterday and things are not looking quite so negative today," said clerk of the course Fiona Needham.
