A powerful blizzard is likely to strike parts of New England and the Mid-Atlantic beginning Friday and lasting into the weekend, with snow totals that are likely to be measured in feet.
The big picture: The joining of weather systems embedded in both the polar, or northern branch, of the jet stream and the southern branch is projected to create a bomb cyclone. Such storms undergo a process known as bombogenesis, with their minimum central air pressure readings plunging at least 24 millibars in 24 hours.
