Sunday's meeting at Kempton will have to pass a 9am inspection if it is to go ahead.
Saturday's fixture was staged as planned, but two morning checks were required before it could be given the thumbs-up and with another cold night in prospect, officials have decided to assess conditions in the morning.
The track tweeted: "We are holding a 9am inspection on Sunday morning ahead of the afternoon fixture. Seven races, first race 1.55pm"
Sunday's meeting at Fairyhouse has been abandoned following an inspection on Saturday afternoon. Officials were due to check the track at 2pm, but they took an early decision with parts of the course found to be unfit for racing due to waterlogging.
Catterick's National Hunt meeting on Wednesday is already in serious doubt after an inspection was called for 9am on Monday.
The North Yorkshire circuit remains covered in snow after a further three inches fell on Friday night and with the turf underneath frozen, clerk of the course Fiona Needham admits the fixture has little chance of beating the weather.
She said: "We have three inches of snow on the track and the ground was frozen before that fell, so we need a minor miracle. Looking at the forecast the temperatures aren't due to rise at all for the next couple of days, so we're looking a bit forlorn."
Leicester's National Hunt meeting on Tuesday has been abandoned due to snow.
Clerk of the course Jimmy Stevenson initially called an inspection for 9am on Sunday, but after a further four inches of snow fell at the course on Friday night, that inspection was brought forward to 10.30am on Saturday and he made the inevitable decision to call off the fixture.
Stevenson said: "It was an easy decision. We have between four and five inches of snow on the track at present and there is no outlook of temperatures rising above freezing for the next four or five days. Underneath the snow the course is frozen in places, so there is no chance of racing on Tuesday."
