The December 25–28, 2012 North American blizzard was a winter storm that impacted the Great Lakes region, northeast United States, and the province of Quebec. The system also spawned a tornado outbreak that impacted areas of the South. At least 16 people died as a result of the storm, and thousands were without power.
An area of upper-level energy that was over the Rocky Mountains on December 24 moved to the Central Gulf Coast, causing an area of low pressure to deepen on December 25. In the early hours of December 25, a mix of rain and snow began to develop as the upper-level trough began to interact with low-level moisture from the Gulf of Mexico. The system intensified as it moved across the southern plains and into the Mississippi Valley on Christmas Day. The system was able to pull in cold arctic air, causing snow and freezing rain in the south (leading to a rare "White Christmas" event for that portion of the country). As the system moved through the Tennessee Valley overnight into December 26, it produced heavy snow, ice, and tornadoes. Thunderstorms formed across the southeast United States, and heavy snow continued in the Ohio Valley. A number areas in the Ohio Valley region, including Dayton, Ohio and Miamisburg, Ohio, and other locations, like Arkansas, also experienced thundersnow. As the day progressed, the system brought snow into the Great Lakes region, and a new low pressure center began to develop in North Carolina. Environment Canada also reported that the system began impacting Ontario that day, bringing heavy snow to the province. The system moved into the Northeast early December 27, with the upper-level trough moving just off the coast of the Delmarva Peninsula. At this point, the storm reached its lowest reported central pressure of 987 mb (29.15 inHg). As the day progressed, the system began to weaken, with the pressure rising, as it continued to move to the northeast, impacting New England, as the system tracked toward the Canadian Maritimes overnight into December 28. That same day, Environment Canada reported heavy and blowing snow over Montreal, Quebec. Early on December 28, the system moved through Nova Scotia, bringing heavy rain and snow before it moved out over the Atlantic Ocean.
Over 200 flights were cancelled at Toronto Pearson International Airport. Several pedestrian and car accidents were reported. A record setting 18 in (45 cm) of snow fell over the Montreal-Laval, Quebec area. The previous record snowfall occurred 41 years earlier in March 1971 when 42 cm had fallen. Numerous road accidents were reported throughout the province, including a 15-vehicle pileup near Saint-Cuthbert, Quebec.
A tornado touched down in Mobile on December 25 with homes and buildings damaged. Almost 300,000 people were left without power. In Arkansas, two people were killed in a highway accident as a result of sleet on the roads. A Louisiana man was killed when high winds knocked over a tree onto a house. On December 25, more than 6 inches of snow fell in Oklahoma and the Texas Panhandle. Freezing rain was blamed for a 21-car pileup on Interstate 35 near Oklahoma City. 40 Oklahoma National Guard soldiers were deployed throughout the state to assist motorists on roads. Two people were killed in separate weather-related car crashes. The driver of a truck was killed in Texas when strong winds knocked over a tree, which fell on the vehicle. Two people were killed in separate weather-related automobile accidents in Virginia.
The National Weather Service issued a blizzard warning for southern Illinois, the first blizzard warning in history for the region. Several counties also closed their courthouses due to the snow. Two people were killed in a traffic accident in Indiana caused by snowy roads on December 26. An 18-year-old Ohio girl was killed when she lost control of her vehicle due to poor road conditions and crashed into a snow plow.
A Southwest Airlines jet slid off its taxiway and got stuck in mud on the morning of December 27. There were no injuries on board, and the passengers and crew all took a later flight to their destination. A man was killed in a car accident while checking on a disabled vehicle near Allentown, Pennsylvania. On Wednesday evening, an American Airlines flight that had safely landed at Pittsburgh International Airport ran over a patch of snow on the tarmac and got stuck for approximately two hours. Nobody was injured in the incident.
