The month of December has started off with a few Arctic air outbreaks into the central and eastern US and while the overall pattern may turn somewhat milder for part of next week, there are multiple signals pointing to additional cold air outbreaks from later next week into the month of January. In addition, the unfolding weather pattern appears to be quite active with numerous storm systems to deal going through the second half of the month of December.
One of the signals for additional cold air outbreaks revolves around an oceanic-atmospheric phenomenon known as the Madden-Julian Oscillation or MJO. A second centers around a phenomenon that features warming over the polar region in the upper part of the atmosphere known as the stratosphere. Finally, a teleconnection index known as the Pacific-North American (PNA) is likely to feature a positive phase for much of the rest of the month and this generally favors high pressure ridging across the western US and Canada which, in turn, is usually favorable for cold air outbreaks to make their way from northern Canada into the central and eastern US.
