There were some screenshots showing some environments that weren't snowy, and if you look at a Skyrim map you'll find a large part of it is in fact snowless.
Don't worry it'll be interesting enough, there are a ton of different environment types. Check one of the threads about the map of Skyrim that was shown in a GI video.

ufff...after seeing the Skyrim map...can't wait to begin exploring!
I don't know why people automatically think snow when they think of skyrim. I think of mountains. Sure, snowy mountains, but its going to be the first elder scrolls games where mountains are done right, judging by the screenshots.
