A bomb cyclone is essentially a winter storm. Collision between two air masses, one warm and one cold, and that sets up currents of air that develop into sort of a rotating storm-like pattern. The air pressure drops really fast. That’s why it’s called a bomb cyclone, is because it develops rather quickly. Meteorologists refer to it as explosive deepening of pressure. By definition, it means that the barometer of the atmospheric pressure drops something like 24 millibars in 24 hours, which is a really, really quickly developing storm. Bomb cyclones are often thought of as winter hurricanes. They’re really different from hurricanes, though, in that a hurricane starts, obviously, much farther south. Bomb cyclone develops much closer to the United States. It also doesn’t have the opportunity to gain as much strength as a hurricane. A bomb cyclone will not develop wind speeds like that at all. So you could have blizzard conditions. You could have whiteout conditions of, you know, 50 mile-an-hour winds and a lot of heavy snow — kind of a bad, a bad winter storm. But that doesn’t always happen. It’s not going to be the worst blizzard you’ve ever experienced, but be prepared for it.
