TEMPERATURES SOAR A DAY AFTER BONE-NUMBING COLD

Temperatures in many areas of the Northeast U.S. climbed to the mid-40s on Sunday, a day after the region suffered through temperatures that plummeted into the negative teens and felt like minus-45 to minus-50 degrees with the wind chill.

Atop 6,288-foot Mount Washington in New Hampshire, the temperature rose to a relatively balmy 18 degrees a day after the actual temperature nosedived to minus-47 and the wind chill was measured in excess of minus-108 degrees.

The warming weather extended to Texas, where thousands of Austin residents were still without power five days after an ice storm knocked out electricity to nearly a third of the city. By Sunday, more than 90% of the city had power, according to Austin Energy. But the lights were still out for 40,000 customers, and there was no timetable for completing repairs.

Back in the Northeast, there was some collateral damage from the extreme cold and high winds.

Boston Medical Center closed its emergency department after a pipe froze and burst Saturday night. It is expected to remain closed until Tuesday.

“All patients in the affected areas of the Emergency Department were safely moved to other areas of the hospital,” the center said in a tweet.

A Providence, R.I., armory being used as a warming center had some of its windows blown out by raging winds on Friday into Saturday, but repairs were soon completed. No one at the Cranston Street Armory was ever in danger, Matthew Sheaff, a spokesman for Gov. Dan McKee, said in an email Sunday. People simply moved to other rooms, he said.
