The latest developments on the severe storms across the U.S. (all times local):
1:30 p.m.
More than 1,400 flights have been canceled across the U.S. and 2,600 have been delayed due to the large storm system moving through the middle part of the country.
Flight-tracking service FlightAware showed that nearly half of the cancellations were at Chicago's two main airports. Another large chunk came from Dallas-Fort Worth International Airport; several tornadoes touched down Saturday in the Dallas suburbs.
Other cities with an unusually large number of cancellations included Houston, Denver, Detroit, Milwaukee, Kansas City, St. Louis, Oklahoma City, and Lubbock, Texas.
A typical day sees about 150 cancelations and 4,000 delays.
Heavy rain and strong winds, like forecast for parts of Missouri, Illinois and Arkansas on Monday, are often more troubling for airlines than snowfall.

Powell said traffic became snarled Sunday night and there were people who were "virtually stationary" in their vehicles overnight. He said Monday a fuel truck was patrolling the area.
Vito Randazzo, of Alpine, California, was driving across the country and was among those who got stuck, beginning at about 8 p.m. Sunday. Around 9 a.m. Monday he was able to see where he could drive across a median and get onto a service road.

Blizzard-like conditions have led to the closure of most of Interstate 40 from Albuquerque east across the Texas Panhandle.

I-40 is the main east-west highway through the state's Panhandle.
The National Weather Service has issued a blizzard warning until 9 a.m. Monday for the Panhandle and several counties in New Mexico. Authorities say that even in areas where the warning has expired, residual blowing and drifting is expected and will make conditions dangerous.
