In US Midwest, 22F 'feels like spring' after days of brutal cold

NEW YORK (Reuters) - Bone-chilling cold that paralyzed a chunk of the United States this week and killed at least 18 people eased as an errant Arctic air mass retreated ahead of a warmer-than-normal weekend in areas of the Midwest and Northeast. In Chicago, where the mercury dipped as low as minus 22 Fahrenheit (minus 30 Celsius) this week, temperatures of 22F (minus 5.5C) felt balmy for some in the nation’s third-largest city. “It’s got to be an almost 50 degree difference, it feels like spring,” said one commuter heading home from Chicago’s downtown financial district, wearing only a sweatshirt. Cable worker Brian Stachovic said he was up an electrical pole for only five minutes on Thursday before his fingers and toes went numb, and he had to go inside to avoid frostbite. “Today, working outside it was like normal,” said Stachovic, 40, wearing brown overalls and insulated gloves, as he worked in Chicago’s downtown. Temperatures from southern New England to the upper Midwest should reach the mid-40s to low 50s Fahrenheit through the weekend and Monday, forecasters said, after a record-breaking cold snap that stopped mail deliveries in some parts of the Midwest and shuttered schools and businesses. “The bitter cold air is going to be pushed up into Canada,” said Bob Smerbeck, senior meteorologist for Accuweather. The Midwest’s worst cold snap in two decades was created by the polar vortex, a reservoir of icy air that usually swirls over the North Pole. Shifting air currents caused it to slip down through Canada and into the US Midwest this week. Temperatures ranged from the teens to the twenties, after cities like Chicago experienced sub-zero temperatures for two days and opened additional warming centers for the homeless.

DEATH TOLL MAY RISE

At least 18 deaths have been linked to the deep freeze since Saturday, and the number was expected to climb as authorities identified more victims. Earlier, police in East Moline, Illinois, about 160 miles (260 km) west of Chicago, said the weather may have contributed to the death of a FedEx freight driver whose body was found between two trucks on Thursday outside a company distribution hub. A representative for FedEx did not immediately respond to a request for comment. The Cook County’s medical examiner’s office said there were four confirmed cold-related deaths this week in the Chicago area. More than 40 cold-temperature records were broken on Thursday, the coldest morning since the polar vortex moved in late on Tuesday, clinging to a swath of the United States from Iowa and the Dakotas across the Great Lakes region and into Maine. Amtrak restored rail service to and from Chicago and the US Postal Services resumed mail delivery in six Midwest states. But while the US Midwest and East Coast thawed out, a fierce winter storm headed towards California, carrying heavy rains and high winds that could touch off city flooding and mudslides.
