Used in Weather Elemental effects routine.  Credit goes to Dokurider for finding it for me. Credit to Talcall for finding the snowy weather flag.

No Parameters 

Returns r2 = 0x00 if 0x800b6698 has flag 0x02 ON (ignore weather ? Inside of building ?)
        r2 = Weather value
        r2 = Weather value + 0x03 if it snows (0x800b6698 has flag 0x01 ON)
