No, Maine weather is not so frigid that it snows in August, but since this will be our first winter in New England, I'm trying to get ready now. Down in Virginia if it snows once during the winter then it is a hard one, so I've been stocking up on gloves and turtlenecks.
You can find some great deals at Goodwill during the summer such as LL Bean gloves for $2, thick socks for $1, and I found a pair of classic duck boots for $25 (normally retailing for $89). Every year I pair up all our outerwear in a big basket, but by February many of the mittens are orphans and there aren't enough hats to go around. I figure that phenomenon is going to happen at twice the rate with actual snow and below zero temps so I better have many more than the usual number of each to start the season.
