What is the weather like in the Adirondack Mountains in late September/early October?

The average temperatures tend to be in the high 40s, with a normal range between 40 and 55. So heavier, Cosby-esq sweaters are advised.  (See below for details.) 

Also, bring a rain jacket. While greater New England falls are crisp, they are not particularly dry. We have between a 30 and 60% chance of seeing at least some rain during the day. (See below for details.) 

Fortunately, there won't be any snow.
