It is best to Google the park headquarters. But they cannot predict either.
I suggest that you visit the Great Basin NPS site online. The park currently lists the road closure as an alert. Currently it reads: "The Wheeler Peak Scenic Drive is closed at Mather Point due to snow and ice." When the road fully opens, this alert will be gone.
Sorry, but no. Live in Oregon and not following the weather. But if you call the visitors center, I'm sure they can tell you.
