January-like cold is on the way for areas of the Midwest that were ravaged by tornadoes on Sunday, bringing dangerous and life-threatening low temperatures to those still without power.
Thirteen counties in Illinois have been declared state disaster areas by Illinois Governor Pat Quinn in response to Sunday's severe weather.
It has been estimated by Mayor Gary Manier that more than 500 homes and businesses have been damaged or destroyed in Washington, Ill., according to WGN Radio.
"We don't yet have a total handle on [the number of people displaced]," Patti Thompson, spokesperson for the Illinois Emergency Management Agency told AccuWeather.com.
The arrival of frigid air may force more people through the doors of the state's six open disaster shelters in the coming days.
Additionally, hundreds are still without power in Washington and Peoria, Ill., making the overnight lows Saturday and Sunday extremely dangerous.
"The highs during the day this weekend can easily feel like the dead of winter cold," AccuWeather.com Expert Senior Meteorologist Bernie Rayno.
Temperatures are forecast to drop 15 to 20 degrees below normal this weekend.
Saturday will usher in temperatures in the 20s with biting wind from the north. The wind will drop RealFeel® temperatures into the single digits and below zero at times.
In the early hours of Sunday morning, the mercury could fall into the teens.
"[Those in the area] need to be prepared. If they don't have heat, they need to seek shelter somewhere that does," Rayno said. "This is a bona fide shot of cold air."
Though the conditions could be deadly overnight, prolonged daytime exposure to the elements can also bring the risk of hypothermia.
The gusty winds forecast Saturday will cause the body to lose heat faster than cold air alone. Those working to clear debris from roadways and search for salvageable belongings are urged to dress warmly.
Hypothermia begins when the core temperature of the body drops below 95 F.
"Anybody caught outdoors and unprepared is at risk," Rayno said.
Despite the Arctic air, the Midwest is in the clear for severe weather for the next several days. The warmth and moisture that brought Sunday's destruction is gone, Rayno said.
Torrential rain and strong thunderstorms pushed across the southern Plains on Saturday, spawning tornadoes and dangerous flash flooding from Kansas to Texas.
An area of low pressure will continue to bring drenching showers and thunderstorms across Italy and the Balkans through the beginning of the week.
Lifeguards along the East and Gulf coasts are preparing to deal with one of the greatest beach dangers: rip currents.
An extremely dangerous and life-threatening flooding situation will continue into Memorial Day, across portions of Texas, Oklahoma, Kansas, Arkansas and Missouri.
Showers and thunderstorms threaten to interfere with Memorial Day festivities across more than half of the United States.
Memorial Day marks the unofficial start to summer and it will definitely feel like it for the holiday and the following few days across the Northeast. However, that does not mean an end to shots of cooler air.
Snowstorm across state; daytime accumulation of 4-6".
