A big concern is that the Ashburton Showgrounds are likely to turn on a typical Canterbury wet-weather day, which will be to Wanganui's detriment, with their speed and attacking prowess.
The MetService forecasts light rain and a temperature of 8C, with an easterly breeze around the 2.30pm kick-off , despite being four degrees warmer and dry in the early hours of the morning.
Wanganui have struggled in muddy games, as highlighted by their 17-17 draw with King Country on September 19 at Cooks Gardens.
Nine of this team were also in the Wanganui side that lost 30-14 in similar drizzling conditions down in Ashburton last September, although of the current starting backline, only halfback Lindsay Horrocks retains his original place. Wanganui were outscored just two tries to one that day, but the goalkicking of Murray Williams and Mid Canterbury's ability to capitalise on mistakes and grind their opposition down were the determining factors.
Today also is the last chance for Wanganui players to press for selection in the New Zealand Heartland XV, before the team is announced on Wednesday.
The Heartland XV will play NZ Marist on November 7, before November 10 and 13 games against the Australian Barbarians - a team chosen from players in the National Rugby Championship who do not have Super Rugby contracts.

1. Mark Andrew; 2. Jackson Donlan; 3. Tama Tuirirangi; 4. Eric Duff; 5. Adam Ross; 6. Tevita Ula; 7. Seta Koroitamana; 8. Jon Dampney (c); 9. Will Mackenzie; 10. Murray Williams; 11. Gideon Lambrechts; 12. Nete Caucau; 13. Matt Thatcher; 14. Ashton Tuck; 15. Andrew Letham.
