More bad news for snow lovers..... While colder temperatures are definitely on the way for this week, mainly Tue-Fri, there is no indication of it being cold enough for snow when precipitation is occurring. And adding insult to injury may be a big warmup just after New Years. There is something called a teleconnection, and while not the be all and end all of weather forecasting, it does correlate upper level wind patterns in different parts of the world to temperature and precipitation patterns worldwide. Two such indices are the Arctic Oscillation and the North Atlantic Oscillation. Generally, negative values of these 2 indices favor colder than normal weather in the eastern US, with positive values inferring the opposite. Both are trending negative now, but are forecast to go strongly positive just after New Years Day. I looked back through history at the last time both were strongly positive, and I came up with January 10-12 of 2006 and January 1-10, 2005. The former featured several days in the 60s, and the latter resulted in 7 days in the 70s! Not exactly the kind of news we snow lovers are looking for......
