Snow grains are a form of
precipitation. Snow grains are characterized as very small (<1 mm), white, opaque grains of ice that are fairly flat or elongated. Unlike
snow pellets, snow grains do not bounce or break up on impact. Usually, very small amounts fall, mostly from
stratus clouds or
fog, and never fall in the form of a shower.
METAR code for snow grains is SG.
