February 1983 North American blizzard

A blizzard in February 1983, nicknamed the "Megalopolitan Blizzard", impacted the Mid-Atlantic, Northeast, and New England regions of the United States. First developing as a low-pressure area on February 9 while a El Niño event ensued, the low then moved eastward across the Gulf of Mexico. While the low progressed across the Gulf, several tornadoes associated with the system touched down across Texas, Louisiana, and Florida, ultimately resulting in ten injuries. The low then emerged over the Atlantic Ocean near the Georgia–South Carolina border, later developing and intensifying into a cyclone as it moved parallel along the East Coast of the United States. The cyclone then moved northward while producing blizzard conditions and heavy snowfall across portions of the Mid-Atlantic on February 11, including across Maryland and northern Virginia. Continuing to intensify and moving northward, the cyclone then brought heavy snow and blizzard conditions to parts of the Northeast and New England. Overall, the blizzard caused 46 deaths and set multiple weather records in terms of snowfall.
