Tonight in Santa Fe, NM, where we are spending the Thanksgiving holiday weekend, I observed one of the most impressive thundersnow events I have ever seen. For a period of about 5-10 minutes, there was frequent lightning, one to two or more flashes per minute, and most of it very close - only a second or two between the lightning and the thunder. The thunder was not as loud as it normally would be from such close lightning; perhaps the snow muffled the sound somewhat. The lightning began suddenly (though we had seen a few distant flashes earlier in the evening) about 20-30 minutes after the snow began. The snow had become quite heavy before the lightning started, and became even heavier after the lightning stopped as suddenly as it had started. I think the burst of lightning may have been associated with an intensification of the storm. The heavy snow lasted about an hour, from 10:15 to 11:15 p.m., roughly, during which time we got about 3 inches of snow at our location.
