It has not felt much like December so far across parts of the United States, but by next week practically nobody will feel like December in the Lower 48 as above-average temperatures take over virtually the entire country.
Although parts of the Northwest and Midwest saw some wintry weather to start the month, it may be quite some time before the next widespread, significant winter storm threatens the Lower 48.
Cold Air Stays Bottled Up North
As we start meteorological winter, which runs from Dec. 1 through Feb. 29, true arctic air remains locked up in extreme northern Canada, well to the north of the U.S. border and even well north of all the major Canadian cities.
While December is early in the winter season, it is quite common for chunks of bitterly cold air to reach the U.S. during the first half of the month.
