Temperatures dropped into the 40s below zero in parts of northern Minnesota on Sunday morning, and Duluth set a daily record low temperature.
The National Weather Service reported a morning low of 41 below zero at Ash Lake and 40 below at Crane Lake.

The Duluth airport's Sunday morning low of at least 26 below zero broke the previous Feb. 14 record low of 24 below, which had been reached four times — in 1875, 1879, 1949 and 1970.
The frigid conditions on Sunday came as a prolonged arctic outbreak continued in the state — and a day after a weather station east of Ely reported a low of 50 below.
Duluth and other locations around Minnesota may break another record on Sunday — the lowest maximum temperature recorded on Feb. 14. Temperatures are forecast to remain well below zero across the state.
