Some of you are probably wondering where this crazy weather is coming from. Hurricane-force winds blew across the plains on March 13th 2019, generating a massive winter storm. That’s Bombogenesis, or a Bomb Cyclone. If the same storm had formed over water, it would have been called a hurricane, and the effects of it covered […]
