There has been chatter for several weeks now that a window would open for a threat either right at the end of the month or very early in December. Folks who are on here daily should have seen that discussed multiple times from multiple posters. I mentioned this to my clients at least 3 weeks ago. I thought the early November warmth would linger a bit longer, but the colder look to very late November very early December is no surprise, nor is the potential for our first true winter threat. Right now, it appears the late Nov/early Dec calls are right on the mark. The question then becomes is this one and done deal that quickly revert back to an AB pattern? I did not have much hope for the mid-December period and have been favoring an AB trend after the early December cold period. There is some support for it to linger a bit longer than I first thought, but I would give it a couple of more eps runs. I noted the other day, I am not a big fan of early December being a great indicator of things to come. I'd be happy if just the position of the modeled high-pressure system next weekend were to be something that gets repeated a few times this upcoming winter.
