After tying a record low on Thursday, Charlotte can expect a slight warming Friday of the Arctic air mass over the region.
Overnight lows were still expected to fall into the teens Friday, although temperatures will recover into the 30s and lower 40s by Friday afternoon, according to the National Weather Service.
Low temperatures will return to the teens and lower 20s again Friday night, with chilly temperatures in the 30s once again Saturday, the Weather Service said.
At least it will stay sunny until Sunday night, when rain is expected to return and linger all day Monday.
Charlotte tied its record low temperature of 8 degrees Thursday morning at Charlotte-Douglas International Airport, the National Weather Service reported.
Charlotte’s temperature last fell to 8 degrees in 1970, the Weather Service said.
The Charlotte area began experiencing the arctic outbreak on Wednesday, a year to the day from last year’s coldest blast.
A burst of polar air spilled into the Carolinas around midday Wednesday, and temperatures tumbled into the teens early Thursday, marking the coldest weather of the season.
Thursday’s high was 28 degrees, or 23 degrees below normal for this time of year, NWS meteorologist Doug Outlaw said.
Duke Energy asked its 4 million customers in the Carolinas to reduce their electricity use Thursday night and Friday morning.
Other lows in the Carolinas on Thursday, from warmest to coldest, included 17 in Myrtle Beach; 14 in Chester, S.C.; 10 in Albemarle, Concord, Monroe, Lancaster and Rock Hill; 9 in Gastonia and Salisbury; 8 in Shelby and Troy; 7 in Hickory; 6 in Statesville; and minus-2 in Boone.
Preparing for the cold
The cold snap had local groups from shelters to schools in preparation mode.
Charlotte-Mecklenburg’s emergency management director Jeff Dulin urged people to sign up for alerts at charmeckalerts.org to receive weather, emergency and other updates by phone, email or text. At the Men’s Shelter of Charlotte, executive director Carson Dean said his agency is ready to handle any increase in usage at its two shelters.
The Humane Society of Charlotte recommends that people keep their pets indoors during cold weather.
Local officials also reminded people of these tips:
• Keep fresh batteries on hand for flashlights and weather radios.
• If pipes are vulnerable to freezing, keep the faucet at a slow drip. Plumbers say it’s best to use the faucet farthest from where water enters the house. And never use an open flame to thaw a pipe.
• Do not burn charcoal indoors because it can produce carbon monoxide fumes.
• Keep at least a three-day supply of nonperishable food at home.
• Keep electric generators outside and away from any open windows or doors.
• Keep cellphones charged.
• Make sure space heaters are in good working order. In the past five years, 1 of every 7 space heater fires caused a death, according to Medic.
• During daylight hours, keep blinds open on the sunny side of the house. The solar heat will help warm your home.
