- Freezing rain to continue over much of Oklahoma, Kansas and Missouri
- Weather has caused at least four deaths across hardest-hit states
(CNN)The icy weather will linger a bit longer.
The major winter storm affecting parts of the central United States and upper Midwest will continue through Monday, according to the National Weather Service.
Significant freezing rain will continue for portions of the Plains and Midwest on Sunday as additional weather systems approach from the west, the National Weather Service said. Cold air will bring snow to the High Plains.
On the southern side of the storm, warmer air may allow severe thunderstorms and heavy rain to develop in Texas on Sunday.
The storm will push north and then east and impact cities like Chicago, Green Bay and Detroit on Monday. It will then head to Rochester, New York, and Springfield, Massachusetts, on Tuesday into Wednesday, said CNN meteorologist Allison Chinchar.
Flooding is expected to return to Northern California by midweek. The Pacific Northwest looks to receive over 10 inches of rain through next Sunday.
Ice in Oklahoma, Kansas and Missouri
More than 30 million Americans are under some type of wintry watch, warning or advisory from the storm in the Midwest, and 10 million of those fall under an ice storm warning.
The hardest-hit states of Oklahoma, Kansas and Missouri will continue to see up to 1 inch of ice coating trees and roads, making travel tricky and potentially bringing power outages to millions of residents.
Oklahoma Gov. Mary Fallin declared a state of emergency for all 77 Oklahoma counties on Thursday. In Kansas and Missouri, nearly 200 National Guard soldiers geared up to provide emergency response assistance to local authorities.
In Missouri, three people have died on highways due to the inclement weather conditions, Missouri Dept. of Public Safety spokesman Mike O'Connell told CNN.
A multi-vehicle crash on Saturday led to one motorist being ejected and struck by an unidentified vehicle going southbound on Interstate 29 in Platte County, the Missouri State Highway Patrol said. Also on Saturday, another vehicle overturned on an ice covered roadway in Nodaway County and the driver was ejected.
On Friday a motorist died after she lost control of her vehicle on an icy overpass on Interstate 55 in southeastern Missouri.
The icy conditions caused another weather-related death in Custer County, Oklahoma. A motorist died during a traffic collision in the western part of the state, which resulted in a multi-vehicle pile up on Interstate 40, the Oklahoma Highway Patrol said.
Playoff game affected
The NFL rescheduled a playoff game because of the ice storm.
The Kansas City Chiefs game against the Pittsburgh Steelers was moved to 8:20 p.m. ET on Sunday instead of 1:05 p.m. ET, due to "public safety concerns in light of the forecasted storm" at the Chiefs' stadium, the league said.
Kansas City was to see significant icing through the morning on Sunday, changing over to rain early in the afternoon. Moving the game back seven hours was expected to reduce the danger of icy roads for those traveling to the game.
Field crews spent the night at Arrowhead Stadium to ensure they could keep the field in good condition, CNN affiliate KCTV reported.
The field was covered with a tarp on Saturday and warm air was pumped in to prevent ice accumulation, KCTV said.
Due to expected power outages and limitations on travel, the Kansas Department of Emergency Management warned citizens to "make sure their home emergency kits are stocked for a 3-day supply."
