For the people reading this who are unfamiliar with snow squalls, they are simply the winter’s version of thunderstorms. You could leave your house in one town with sunny conditions and then by time you reach the next town over, you are experiencing blinding, heavy snow. Snow squalls are one of the most dangerous weather phenomenon’s for this exact reason. It is imperative that you keep a close eye on the radar tomorrow.
