A major snowstorm tracked across the Midwest last weekend, bringing the region its first significant snowfall of the year and dangerous travel conditions for motorists.
Chicago O'Hare International Airport reported 11.2 inches of snow, good for the second-largest November snowstorm in the city's history. More than 275 arriving and departing flights were canceled on Saturday afternoon.
"The snow that moved into the Great Lakes on Saturday first spread snow across the central Plains on Friday, Nov. 20, near the border of South Dakota and Nebraska into Iowa," AccuWeather Meteorologist Kristina Pydynowski said.
The heaviest swath of snow fell from southeastern South Dakota to northern Iowa and northern Illinois, according to Pydynowski.
By Thanksgiving night and Black Friday, another storm was slamming the central U.S., bringing significant icing from West Texas to Kansas and Missouri. Heavy rain, capable of producing flooding, spread from the Plains into the Midwest.
Several days after a powerful storm claimed at least three lives and left more than 300,000 without power in Washington, more severe weather targeted the Northwest this week.
Tropical activity resumed in the East Pacific as Sandra formed south of Mexico. The system grew from a tropical depression on Monday to a Category 4 hurricane on Thursday.

Two magnitude 7.6 earthquakes struck just minutes apart in eastern Peru near the Brazilian border on Tuesday night.
There was no reports of damage or injuries, but Reuters reported that the quake occurred in a sparsely populated jungle region and was unlikely to cause major damage.
