Here's Rodney Boyette of Annapolis: "As we approach that time of year when we hopefully will hear snow in the forecast, please explain the difference between 'snow showers' and 'snow flurries.'" Hopefully? You must be a teacher. The National Weather Service defines a snow flurry as an "intermittent snowfall of short duration" with no measureable accumulation. A snow shower is "a short duration of light to moderate snowfall." Accumulations are "possible." A heavy snow shower with sudden, strong winds is a snow "squall."
