It will be fine. I had sprouts coming up and then we got 6 inches of snow on April 1st. The snow now is all melted and each has about 10-15 sprouts (2nd year) coming up.
The snow would actual help insult them from frost, but you can cover them at night with a sheet to protect them if possible. Here in NH, I don't consider threat of frost to pass until at least Mother's Day.
