If you thought you heard thunder in Vancouver last night, you weren’t imagining it. However, it was not just any ordinary thunderstorm.
According to The Weather Network’s Digital Meteorologist Tyler Hamilton, it was a rare thunder snow.
How rare?
“Thundersnow is so rare, we don’t have a proper icon for it,” he tweeted. “But it made the observation at YVR.”

An observation report from Vancouver Airport confirmed the weather incident, describing it as a “thunderstorm with light snow.”
Thunder snow mostly occurs in the Great Lakes region, according to the Farmers’ Almanac.
It happens when “cold air blows across the relatively mild water of the Great Lakes, forcing the air upwards rapidly enough that the instability causes lightning and thunder in conjunction with heavy snow.”
One Burnaby resident caught it on video, which shows snow falling as a flash of lightning lights up the scene.
