From the Dark Forest to the northern plains is six hundred miles south to north, similar to the distance from, say, Montreal to Norfolk. From Hightown to Erventon is four hundred miles. This is all temperate region. The Leather Road gets snow perhaps two months out of the year, from mid-December to mid-February. Further north there is more snow, and in the Deep Forest the things that live there grow unchecked year round without the cleansing effects of winter except for once every ten years or so, and that does not last.
Crosspoint, on the bay, receives little snow during the winter months, but may occasionally receive some. Watertown, a mere sixty miles north, generally receives snow once or twice a year, and sleet a little more often.
Northward, in Stone Goblin, the Long Lakes, and Erventon, snow can arrive as early as late October, with occasional last gasps in early April. Usually, it will snow sometime in late November or early to mid December and partially melt in late February. In the Long Lakes, the weather is often more unpredictable due to the effect of the lakes.
