An active weather pattern this week with multiple systems to deal with in the Mid-Atlantic region. Weak low pressure will pull away from the area this morning, but it’ll be quickly followed by another system likely to produce more rain around here from later tonight into early Tuesday. Yet another low pressure system should affect our region from later Wednesday into early Thursday bringing more rain to the region. Colder-than-normal air will follow for the late week and the upcoming weekend and it looks like it’ll stay quite cold right into the first part of Christmas week.

It’ll stay well below-normal today in the Mid-Atlantic region, but the winds will not be a factor as they were on Thursday. An overall active weather pattern is unfolding going forward and there will be a couple systems to deal with early next week. By late Sunday, weak low pressure will bring moisture into the Mid-Atlantic region and it can be cold enough at the onset (cold air damming scenario) for a mix of snow and/or ice across some of the far N/W suburbs. Another system will follow quickly on Monday and Tuesday bringing some rain to the Mid-Atlantic region.

It’ll stay well below-normal today in the Mid-Atlantic region, but the winds will not be a factor as they were on Thursday. An overall active weather pattern is unfolding going forward through the second half of December and there will be a couple systems to deal with early next week.

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.
