Arctic air strengthened and peaked early Saturday morning, with the coldest air in nearly 7 years.
The sun is out, but that doesn’t help, as temperatures remain feeling 25 to 50 degrees below 0 across New England.
With no doubt, temperatures are the coldest north of the Merrimack Valley and the Monadnock Region.
Officials are urging people to take precautions, check on their neighbors and call 911 if you see an unhoused person outside.
