LOL I agree he doesn't look happy!
We usually get about 2-4 inches at most when it snows here, and we get about 3-4 snows a year in that range, otherwise just dustings. Usually doesn't stick around long either.
My daughter's yearling loved the snow last year... can you tell? lol
Like everyone said, try to help keep out drafts, dry bedding, lots of hay on cold days/nights, make sure the water doesn't freeze, if it does don't fill the buckets up too full, just a little and try to check it often. If buckets are frozen, we safe milk jugs that we've cleaned out, fill them with warm/hot water, and pour those to break the buckets. As it melts the ice, it also cools the hot water a bit, so that they enjoy it
You can keep an old sweater on hand that you can cut the sleeves off of about half way up in the event you need to help anyone stay warm such as in times if a goat is feeling under the weather, etc.
