Midweek Nor’easter Alert: Snow Blowers Needed in DC or Glancing Blow?

A storm system will impact the Deep South on Tuesday, eventually moving northeast toward the Mid-Atlantic coastline on Wednesday.  The eventual track, timing and temperatures are uncertain at this time with differences among the various forecast models.

Here is a look at the current potential snowfall accumulations among several of the main forecast models from weatherbell.com:

The track of this system is still very uncertain given a wide-spread among each model’s ensemble computer runs.  The NAO index is still in its positive phase and given the wide difference in the GFS and European, it is too early to give any weight to either model.  Models will hopefully come into better agreement on Monday afternoon.  Stay tuned.

  1. Certainly an nteresting situation and at least the 18Z GFS trended a little more “bullish” for snow, which is not a bad sign.

  2. BRING IT!
    Wow, look how that first model shows us with nothing… So I bet we’ll be in some type of 2″-14″ range and then we’ll only get 1.5 🙂
