I was just filming my daughter and Bullmastiff playing in the snow. At about the 22 second mark I suddenly heard what sounded like thunder and it lasted for more than 30 seconds but I thought you couldn’t have thunder during a snowstorm. It obviously startled my dog as well! Evidently thunder snow is a rare phenomenon that occurs in 0.07% of snowstorms! Thanks for entertaining my family with your clips over the years! 😊
