Temperatures are expected to climb to a high of zero or 1 today as an arctic air mass is hanging over the area, said meteorologists at the National Weather Service station in Aberdeen.
"It's not really moving anywhere too quickly," said Travis Tarver, a meteorologist.
The temperature bottomed out around 8 a.m. at 11 below zero, Tarver said. Wind chills are at negative 25 and are expected vary between 25 to 15 below zero throughout the day, he said.
While the low temperature this time last year was minus seven, the high was at 23 degrees, Tarver said.
"It won't be anywhere near 23 (today)," he said.
The lowest temperature for the 2011-12 winter was minus 13 in January 2012. The lowest temperature so far this winter was minus 17 in December.
Throughout the week, temperatures will rise to single digits above zero and perhaps as high as 10, Tarver said.
