Thursday's jumps meeting at Market Rasen is subject to a precautionary inspection at 8am, joining Wincanton and Leicester in needing checks before racing.
Officials have called an early check in light of a forecast for light frost at the Lincolnshire venue, with the going good to soft, soft in places.
Raceday clerk of the course Robert Bellamy said: "The forecast is for a minus 2C frost, but a possible wind chill of minus 7C, the east side of the country is particularly cold.
"We are perfectly raceable, it's not like we've had frost after frost, but we wanted to be prudent and warn people in case the forecast is wrong when one isn't so bad and another is horrendous."
Thursday's meeting at Wincanton must also pass an 8am precautionary inspection, with overnight temperatures set to drop to minus 2C or possibly even lower.
Clerk of the course Barry Johnson said: "I'm very confident we'll be fine - we'll be OK with minus 2C - but some forecasts are predicting minus 4C. There's no frost in the ground now, but the ground is quite wet. It's very much a precautionary inspection."
Leicester also have an issue with frost, as temperatures set to drop to as low as minus 5C.
A maximum daytime temperature of 2C on Thursday has also been forecast.
Clerk of the course Jimmy Stevenson said on Wednesday morning: "There's no frost whatsoever this morning - we are perfectly raceable - but there is quite a severe frost forecast tonight.
"If we think we have a chance at 8am, we'll probably call another inspection later in the morning and then, possibly, look again. We've got to be patient."
