Snow in Tunisia?

[76mm]

I'm sure this sounds strange, but I'm thinking about making a campaign involving a fictional country which would use East Front (German, Sov) units but the Tunisia map (basically using Tunisia to create a mini-Russia). Using the East Front OOBs and graphics seems easy enough, as well as changing the town names, but there might be one major problem...

The problem is snow...can't have an East Front game without snow, but I presume that the Tunisia game would not include snow weather effects like the East Front games, but I don't have the game to check--could someone please confirm?

If the game doesn't include snow as part of the game, is it possible to use the parameters file or something else to get snow effects?
