Normally, I think it is a good idea to just do one month per pattern discussion.  Since we are half-way through December, I say let's put Dec/Jan into one discussion in terms of sensible wx patterns.  For upcoming and short range events, such as this weekend, use Stovepipe's.  This thread will be for discussing the upcoming early to mid-winter pattern.  The pattern looks blocky upcoming, but the NAO says nah.  The southeast ridge could be to our benefit depending on where it sets up shop.
