Wedding

Can you tell me the weather for Hunter Mountsin 10/13/18. It’s for a wedding. Thank you

Hunter Mountain

We are predicting “a few showers, cool,” for Oct 7 to 13, followed by several days of sunny, mild weather.

Dec 15 and 22

Have a Christmas Party Dec 15 or Dec 22, which day is better?

Dec 15 or 22?

Both are within rainy, mild periods, but Dec 22 is the day of the Full Cold Moon and the first official full day of winter. If that doesn’t help you to decide, toss a coin … until you get the one you want.
