While I don't know much about the mysteries of snow—Witches make it, right?—I do know that the best music to accompany the bad weather we've been having is something emo, and preferably Scottish.
Thankfully we're in luck with the Twilight Sad who fulfill both prerequisites while adding their very own sense of impending doom to each and every song they deliver; hence titles like "Here, it Never Snowed. Afterwards it Did." The Scots do sadness quite well—that would explain why I cry every time I hear Nazareth's "Love Hurts"—but not even Belle & Sebastian can touch the misery of the Twilight Sad. Perhaps the two bands should conduct a sad-off? I volunteer my services as a judge.
