Usually, I post here when I've written new Pathfinder rules over on my blog.
This latest post is a little different. I've tried to repost all of the relevant rules on cold-climates from the Core Rulebook, reformatted so that articles aren't referring to other articles, and regrouped into four sub-sections (ground conditions, snowfall, wind, and temperature) so that you can mix-and-match them to create various weather conditions. And, in a few places, I clean up areas where the rules are unclear or inconsistent.
