wintry

adj. resembling winter (i.e. cold, rainy, snowy, stormy, etc.); gloomy, cheerless

Winter is one of the four seasons of temperate zones. Almost all English-language calendars, going by astronomy, state that winter begins on the winter solstice, and ends on the spring equinox. Calculated more by the weather, it begins and ends earlier and is the season with the shortest days and the lowest temperatures. Either way, it generally has cold weather and, especially in the higher latitudes, snow and ice.
