2/1/2019 12:41:00 PM Weekend rapid thaw is unprecedented
CHICAGO (AP) — The bitter cold that gripped the Midwest forced commuters to bundle up like polar explorers. By early next week, many of those same people might get by with a light jacket.
Just days after the arctic conditions, forecasts say, the region will seemingly swing into another season, with temperatures climbing by as much as 80 degrees. Experts say the rapid thaw is unprecedented, and it could create problems of its own — bursting pipes, flooding rivers and crumbling roads.
“I don’t think there’s ever been a case where we’ve seen (such a big) shift in temperatures” in the winter, said Jeff Masters, meteorology director of the Weather Underground firm. “Past record-cold waves have not dissipated this quickly. ... Here we are going right into spring-like temperatures.”
Although many places remained painfully cold Thursday, the deep freeze eased somewhat, and the system marched east. In western New York, a storm that dumped up to 20 inches of snow gave way to subzero temperatures and face-stinging wind chills. Today, the wind chill in some areas was expected to be as low as minus 20 degrees.
Schools remained closed in Buffalo, New York, but students headed back to school in other parts of the Midwest. Educators in Fargo, North Dakota, were busy Thursday after two days of canceled classes. For Superintendent Rupak Gandhi, who came to Fargo last summer from Colorado, this week has been “a personal new.”
“I’ve had experience with cold and snow days, but negative 50? Absolutely not,” he said.
The dangerously cold weather is suspected in at least 17 deaths, including a man found frozen in his backyard in a Milwaukee suburb and a homeless man whose frozen body was found in a western New York bus shelter. Both men were found Thursday, the same day temperatures plunged to record lows in several Midwestern cities.
But relief from the bitter Midwestern cold is as close as the weekend. Rockford, Illinois, was at a record-breaking minus 31 degrees on Thursday morning but should be around 50 degrees on Monday. Other previously frozen areas could see temperatures of 55 degrees or higher.
The dramatic warm-up will offer a respite from the bone-chilling cold that canceled school, closed businesses and halted trains. But potholes will appear on roads and bridges weakened by the freeze-thaw cycle. The same cycle can crack water mains and homeowners’ pipes. Scores of vehicles will be left with flat tires and bent rims.
The thawing of the pipes can sometimes inflict greater damage than the initial freeze. Bursts can occur when ice inside starts to melt and water rushes through the pipe, or when water in the pipe is pushed to a closed faucet by expanding ice.
Still, memories of the dangerous cold were bound to linger.
In Illinois, at least 144 people visited hospital emergency rooms for cold-related injuries over two days. Most of the injuries were hypothermia or frostbite, according to a spokesman for the state Department of Public Health.
The effect on the overall economy was not expected to be that great, in part because there were no widespread power outages such as there are in a hurricane.
“People may be in their homes, but they can do things such as online shopping,” said Mark Zandi, chief economist at Moody’s Analytics. “Life goes on.”
