PORTLAND, Maine — Frigid weather returned to the Upper Midwest on Thursday after a storm that swept up the East Coast delivered a blow to New England, packing powerful gusts that knocked out power along with a deluge of rain and warming temperatures that washed away snow and dampened ski resorts.
The Upper Midwest saw unseasonably cold early Thursday, with parts of North Dakota, Minnesota and Wisconsin experiencing wind chills well below zero degrees F (minus 17.8 degrees Celsius). The National Weather Service received a report of a low temperature of minus 27 degrees F ( minus 32.7 degrees C) southwest of Inger, Minnesota. States to the south, including South Dakota, Nebraska and Iowa, saw wind chills in the single digits Thursday morning.
In Chicago, gusts of more than 40 mph (64 kph) Thursday coupled with a low temperature of 4 F (minus 15.5 C) at O'Hare International Airport to create a stinging wind chill of minus 28 F (minus 33.3 C). City officials designated more than two dozen community and senior centers to be used as warming shelters and urged the public to avoid unnecessary trips outside.
The weather service also issued freezing spray warnings on Lake Superior and Lake Michigan, with subzero temperatures and high winds resulting in up to an inch of ice per hour accumulating on ships and smaller vessels.
On Wednesday, an atmospheric river transported moisture northward from the tropics and brought heavy rain.
The city of Portland, Maine, got 2.33 inches (5.92 centimeters) of rain Wednesday, breaking a record of 2.01 inches (5.1 centimeters) for the date set in 1887, the National Weather Service said.
Utility workers were deployed to handle power outages after winds peaked Wednesday night into Thursday. Nearly 90,000 customers in Maine had lost power as of Thursday morning, according to poweroutage.us.
A deepening low pressure system was responsible for winds that lashed the region, said Derek Schroeter, a forecaster with the National Weather Service. Some areas in Maine had wind gusts of over 50 mph (80 kph).
