Big picture reminder-
Of all the indices we track, historically a -AO, especially when combined with a -NAO, correlates to higher probability for cold and increased chances for snow for the DC area. All guidance forecasts -AO/NAO in addition to a neutral/+PNA and -EPO for early Jan. No guarantees as we always need some luck with timing, but this gives us a hell of a chance to achieve the desired outcome, entering prime time snow climo.
