February 12–14, 2017 North American Blizzard
The February 12–14, 2017 North American blizzard was a strong and historic nor'easter that affected the Northeastern United States and Eastern Canada from February 12–14. It impacted the Northeastern United States less than a week after the February 9–11, 2017 North American blizzard. This blizzard was more localized and less widespread than the previous storm, but snow totals were higher in some areas, including portions of Maine and Vermont. The system caused 2 fatalities and is estimated to have caused over $3.9 million (2017 USD) in damages. It was unofficially named ''Winter Storm Orson'' by The Weather Channel. Meteorological history The system originated as a weak low-pressure area (meteorology), low-pressure system over the Great Lakes region early on February 12, which quickly began to strengthen due to abundant moisture. It quickly moved eastwards into the Mid-Atlantic (United States), Mid-Atlantic states by 18:00 Coordinated Universal Time, UTC, with precipitatio ...

Extratropical Cyclone
Extratropical cyclones, sometimes called mid-latitude cyclones or wave cyclones, are low-pressure areas which, along with the anticyclones of high-pressure areas, drive the weather over much of the Earth. Extratropical cyclones are capable of producing anything from cloudiness and mild rain, showers to severe hail, thunderstorms, blizzards, and tornadoes. These types of cyclones are defined as Synoptic scale meteorology, large scale (synoptic) Low-pressure area, low pressure weather systems that occur in the middle latitudes of the Earth. In contrast with tropical cyclones, extratropical cyclones produce rapid changes in temperature and dew point along broad lines, called weather fronts, about the center of the cyclone. Terminology The term "cyclone" applies to numerous types of low pressure areas, one of which is the extratropical cyclone. The descriptor ''extratropical'' signifies that this type of cyclone generally occurs outside the tropics and in the middle latitudes of Ea ...
