(Ok i found out what a scud is) Scud cloud - Low ragged and wind-torn appearing cloud fragments, usually not attached to the thunderstorm base, often seen in association with, and behind gust fronts. Scud clouds DO NOT produce severe weather. Scud clouds are often mistaken for wall clouds and tornadoes, especially when attached to the thunderstorm base. A way to differentiate scud clouds from wall clouds is to watch their relative position with respect to the rain area: scud clouds move away from the rain area while wall clouds maintain the same relative distance
