A mix of wintry weather advisories and warnings are expected to extend from the Northwest throughout Texas to the southern border, and into the Northeast early into the week.
On Saturday, historic snowfall amounts landed in Seattle that reached 9″, the most since 1969. To the south in Portland, Oregon, over 200,000 people were left without power and 10″ of snow.
Over 168 million people were under weather advisories on Sunday night, with snow expected from Texas to Maine. Ice is a big concern in the South and Northeast, with polar air extending from the already frozen Midwest to the Gulf Coast.
The National Weather Service said that parts of the Northwest could receive another storm system that would bring more than a foot of snow to parts of the Cascade range in Idaho, Wyoming and the central Rockies.
Oklahoma City was at 12 degrees Sunday night, with a wind chill of -15.
In a very rare occurrence, all 254 counties in Texas are under a winter warning. The temperatures in Texas are already colder than Anchorage, Alaska. Governor Greg Abbott issued a disaster declaration and asked for federal assistance. He got it (without conditions).
