My next long-range forecast discussion will probably come out this Friday, though I will try to post it sooner.
In last week's discussion, I explained that the core of the Arctic air will extend from the northwestern U.S. into the Northern and Central Plains and Upper Midwest as we move into the beginning of December. The eastern U.S., especially across the South, will only experience brief, 1-2 days of colder weather before temperatures rebound each time.

But then things will change. A strong Greenland block will build in early December, resulting in the eastward and southeastward expansion of the colder temperature anomalies. The Southeast will probably be the last to experience any noteworthy, Arctic air, but after about the first 8-10 days of December, things may start getting interesting, temperature and precipitation-wise.
More soon in my next long-range forecast later this week.
