According to Brettschneider's map, a swath of the nation's mid-section, northern New England and eastern New York state generally saw the lowest temperatures in December.
Southern New England through the mid-Atlantic, parts of the Southeast, Gulf Coast and West experienced their coldest temperatures in January.
South Florida, portions of eastern Georgia, western New York, central Pennsylvania, northern Michigan and California's Sierra Nevada saw winter's lowest temperatures in February.

Much of Alaska experienced its coldest temperatures in mid-to-late January, but some areas near the coast in south-central and southeast Alaska didn't hit the lowest temperatures until February.
Brettschneider told weather.com that only one U.S. weather station, so far, set its coldest winter temperature after March 17. Morrisville, Vermont, plunged to -11 degrees on March 18, after Winter Storm Stella.
