雷打雪(英语：thundersnow）中国又称雷打冬，是指某个区域降雪过程中伴随着打雷或者在冬天打雷的天气现象。这种天气现象非常罕见。

当某个区域冬季的气温偏暖的时候，暖湿空气相对旺盛，如果在这种情况下暖湿空气与另外一个区域的强冷空气相遇，剧烈的温差会使暖湿气流会迅速抬升，气流加剧，造成强烈的对流天气，这样便给“冬天打雷”提供了机会。同时湿度较大的空气在冬季会造成雨雪天气，所以人们常说“冬天打雷雷打雪”。

Thundersnow, also known as a winter thunderstorm or a thunder snowstorm, is an unusual kind of thunderstorm with snow falling as the primary precipitation instead of rain. It typically falls in regions of strong upward motion within the cold sector of an extratropical cyclone. Thermodynamically, it is not different from any other type of thunderstorms, but the top of the cumulonimbus is usually quite low. In addition to snow, graupel or hail falls.
