I mean it sort of doesn't make a lot of sense here in Australia (curious to know if any new lines for Junkrat and Roadhog reflect this), though if the weather keeps flipping on its head here... it might even be prophetic. At any rate, Blizzard has released its "Winter Wonderland" update for Overwatch, which features a number of additions to the game.

Here's the official snowball:
