There is little doubt now that the coldest air of the season so far will reach Delmarva by Thursday, and highs Thursday and Friday will not likely reach freezing. We may even see some snow early Saturday, before it changes to rain as milder air arrives. While it is very long-range, there are growing indications that the last ten days of the month will be much warmer in the Eastern U.S. with the holidays seeing normal to above normal temperatures, all the way to New Year’s Eve.

Long range gudiance for late November shows a strong westerly wind flow over Nroth America. This should allow milder air to reach the eastern U.S. It will be rather cold near the Canadian Border.

The southeast U.S. will likely be very mild with well above normal temperatures. This is long-range, but several different model runs have indicated this, and the polar flow also supports it.
