I love cold weather - crisp, windy days when you can smell the pureness in the air. Cold, wet days can suck themselves into a drainpipe, however, as that means I can't go walking outside to enjoy the cold as I am wont to do normally - or go explore the woods, Larch Mountain, etc.
Also, I abhor heat, unless it is a fire being lit against the cold. Fire is lovely.
Oh, and lightning (i.e., real) storms make me happy - I miss them, and the not-freezing rain that one could run through and shout to the sky in time with the thunder claps.
