Still! Even after the latest patch. I'm seeing winter snow throughout Texas (including Loredo and Tucson), as far south as Houston. All thru the deep south, including New Orleans. Just not right!

More weather tweaking needed IMO. There really needs to be a "no snow" line set in this game, south of which it will not occur. Convert to mud instead.
