I observed and videotaped a thundersnow event in Santa Fe, NM, the afternon of March 19, 2010. This is the most intense thundersnow I have seen, in terms of the frequency, amount, and closeness of the lightning - When viewing the video, note that often the thunder comes just a split-second after the lightning. This storm dropped about an inch of snow in a half hour, starting out as mostly graupel (snow pellets) and ending as ordinary snow.
