North American English needs a lot more terms for phases of seasons than it actually has. There’s “Indian summer” for a warm spell in late fall; but there’s no corresponding term for thaws in early spring, the ones where you never know until after the fact whether it’s the thaw, or whether at least one freeze and/or heavy snowfall is in the works.
I say this on account of we are having one of these spells right now, and I don’t know whether to tempt fate by going “yay spring is here!” or to hedge my bets, and having a single word or short phrase to do that in would be nice. So I’m going to dub this weather springoid. Right now we are in springoid, a collection of distinct though related spring-like objects. Maybe they’re all the same, and this is actual spring! Or maybe there will be one or more winter-like object intervening! Who knows?
At any rate, permanent or not, going outside no longer hurts the face, and there are signs and smells of life. This comma butterfly (Polygonia sp.; most likely an Eastern comma Polygonia comma) has most likely over-wintered as an adult, curled up in the bole of a tree or some human-made crevice:
