Thundersnow has been reported in several parts of Missouri during a winter storm that continues to hit Missouri. This video of it was recorded at the Missourinet in Jefferson City, Mo. at Learfield Communications. The lightening flash can be seen at about 15 seconds into the video, and the rumble of thunder was audible for more than a minute after the flash.
Thundersnow is a rare weather occurrence that happens when snow falls instead of rain in a strong upward motion within a cold sector of a front. A unique aspect of thundersnow is that the snowfall acts as an acoustic suppressor of the thunder, meaning it can be heard many miles away. Weather experts say thundersnow often produces snowfall rates in the range of 2 to 4 inches per hour.
