Magic is going to try. C’mon Sugarbush! Make snow!
Historically speaking, Sugarbush is not one of the resorts that plays the "resurfacing via snowmaking" game after a thaw/freeze event. They rely on grooming to fix the surfaces. Their snowmaking strategy is to make the amount of snow they need on each trail to get through the season in 1 main shot (with the exception of going back to add depth to the spring trails once primary snowmaking is completed on all other trails).
I'm not going to say they've never made snow this late to resurface some key areas...just it is very unlikely and not their SOP so don't get your hopes up.
