Snow in Sand Dune in Tottori?

Hi! My partner and I are planning to do a daytrip from Osaka to Tottori for the Sand Dunes and other nearby sightseeing spots we can go to. It will be a 3 hour bus ride if ever and the earliest we can arrive there is 9:52 or 10:52 and the latest we can leave there is either 6:40PM or 8PM. The main reason we want to go there is to see the sand dune covered in snow. Our tentative date for this is on January 27, does anyone have an idea if there will be already snowfall on the area at this time? If not, we might forego it. Thank you!
