Ken Hilton, the Southport secretary, said he was 'very confident' that the match would be played.
Speaking to mansfieldtown.net at 9.25am this morning, Mr Hilton said: "I was on the pitch at 7.55am today and there was no snow on the pitch, it was soft on foot. I'm very confident the match will go ahead.
"We do have light snow now [as we speak] but that should clear by mid-day.
"We've had no frost in the last two nights and if we were playing today the match would be on," he added.
Temperatures are expected to dip over night, however, and as a precaution, Southport have called an 8.30am pitch inspection before the Stags' team coach sets off tomorrow morning.
