In Wisconsin and Minnesota, century-old temperature records were broken in the days leading up to Christmas, which also means 2023 will not bring a “white Christmas” in states that usually get snow. The high temperature during the day in Milwaukee exceeded the record set in 1877 when it reached 7 degrees on Saturday and Sunday, while the city of Rochester, Minnesota, recorded a high of 12 degrees on Monday, Christmas Day. The weather in the Great Lakes region and Midwestern states was 10 to 15 degrees cooler than average. But over the weekend, dense fog made travel difficult, with hundreds of flights canceled and more delayed.
Mild weather was brought to an abrupt end by a winter storm arriving from the west on Christmas Day, bringing snow, high winds and freezing rain to the plains and mountainous areas of the northwestern states. Transportation officials have issued a snow warning for Nebraska.
In the last days of the year, the temperature will fall below freezing in most parts of the United States, except for the southern states, but during the day it will rise above zero almost everywhere.
In Canada, Christmas and the days leading up to the holiday also brought unusually mild weather, so the daily high temperature in Alberta approached 15 degrees, and 13 degrees was measured in Toronto a few days ago.
