You may have heard talk of a “bomb cyclone” snowstorm that could impact Massachusetts this weekend. A bomb cyclone is a storm that undergoes “bombogenesis,” meaning it rapidly intensifies within a 24-hour period, according to the National Weather Service. Bombogenesis often occurs when a cold air mass collides with a warm air mass, according to the weather service. Is a bomb cyclone coming to Mass.? If this were to happen, the bomb cyclone could wreak havoc on more of the state.
