on a cloudy, windy night

"Since the heaviest snow usually falls during the month of February, Native American tribes of the north and east most often called this month’s full moon the Full Snow Moon. Some tribes also referred to it as the Full Hunger Moon or Little Famine Moon, since harsh weather conditions in their areas made hunting very difficult. Forced to gnaw on bones and sip bone marrow soup for sustenance, the Cherokee named it the Full Bony Moon.

Around the globe, the Celts called February’s moon the Moon of Ice, while the more optimistic Chinese named it the Budding Moon in anticipation of spring."
