AccuWeather's Ariella Scalese explains the different types of precipitation that occur during the winter season - and how they form - from freezing rain and sleet to graupel.

Breakdown
  • Three key temperature factors—surface, warm layer above ground, and cloud temperature—determine winter precipitation type. 16s
  • Surface temperatures at or below freezing allow for snow, freezing rain, and sleet; above freezing, rain or wet snow may occur. 23s
  • A warm air layer above the surface can melt falling snow into rain or a mix, and if it refreezes near the ground, it can become sleet or freezing rain. 38s
  • Cloud temperature and depth affect precipitation type and intensity; colder, deeper clouds favor snow and heavier precipitation. 57s
  • Graupel forms when supercooled water droplets freeze onto snowflakes, creating rounded pellets often mistaken for hail. 1m 40s
