Wednesday's meeting at Catterick has been abandoned.
Clerk of the course Fiona Needham reports the weather to have been slightly warmer over the weekend, but with snow on the track, there is no prospect of racing.
She said: "It's not actually been that cold over the weekend but it's snowing again as we speak and it's not going to improve. Our next meeting is February 1 so let's hope things have improved by then."
Exeter's card on the same day still has "a glimmer of hope" after clerk of the course Barry Johnson called an 8am inspection for Tuesday.
The track currently has a covering of snow but a new front is forecast to move in tonight which could bring either rain, sleet or snow. If it falls as rain, the meeting could still go ahead.
Johnson said: "We've got a glimmer of hope. We're not too sure what's going to fall overnight, it could easily be snow which would give us no chance, but it may be rain or sleet which would help shift the snow. We'll know by 8am."
Prospects at Ayr have taken a turn for the worse with snow now forecast.
The British Horseracing Authority put on an extra fixture at the Scottish track on Wednesday as it was thought it would escape the worst of the weather. Until the last 24 hours there were no problems reported, but the meeting is now somewhat in the balance.
Clerk of the course Emma Marley said on Monday: "We are perfectly raceable at present. We were 1C overnight and 2C yesterday. However, the forecast is for light snow tonight and into tomorrow morning, one to two centimetres.
"We'll have a better idea of our chances in the morning, but the forecast is slightly problematic. All we can do is wait and see as it is coming in from the east coast and it is quite heavy over there."
