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.
