Light snow refers to a steady snow that is lightenough in intensity to keep the visibility above 1/2 mile (as defined by the National Weather Service, therefore this may be different outside the USA). Accumulations will range from nothing to a couple inches at most in a 24 hour period.

Snow showers are defined by their "off and on" nature and varying intensity, and therefore there is no intensity connotation in the term. A more dynamic atmosphere is conducive to snow showers, which are typically associated with lifting mechanisms such as orography or convection from the Great Lakes (lake effect snow), for example. Accumulations can range from nothing with a brief shower to over a foot in intense and persistent lake effect bands and favored regions in the mountains.
