Snow has been hard to come by so far this winter. No reporting sites in central Illinois have reported an inch or more of snowfall through Christmas. This is in stark contrast to recent Decembers which started-off as active snow seasons. Precipitation has actually been above normal for the past several weeks, but mild air masses have allowed almost everything to fall in liquid form.
Elsewhere, another storm system will reach the Pacific Northwest resulting in additional precipitation. Moisture will gradually spread eastward across the nation’s northern tier, with some periods of locally heavy snow possible in the Great Lakes region.
As the New Year begins, a blast of very cold air, perhaps the season’s coldest, will arrive across the eastern half of the U.S.
