7:45 p.m. Thoughts on Inconsistency with the models.
My thoughts with what is going on with the models is that I think they are confused. The latest GFS model looked promising in the beginning and then everything started to fall apart. I believe it is because the models just are not into their deadly range where all the runs are pretty similiar. Although the GFS model has been consistent with an OTS solution, it starts out as if it is going to go up the coast and spread snow through out the Northeast. Also the past two GFS runs are a lot more different than what you initially see, until you see the run before it. The 18z run is North and in fact a little west until it reaches NC. Thats when it decides to go OTS. The 12z run also is more east and is not as much of a defined storm, the precip is kind of strung out and not typical. That is because this storm is 5 days away. As we continue over the next few days i do expect for the GFS to be more defined, more like the Euro, and move a bit more west and have that negative tilt that we are looking for. With the Euro model, which i believe is ahead of most of the model, shows a much more defined Low pressure system that heads NE and ends up just a bit East of Long Island. With a 982 mb low there will be a bigger precip shield but that comes with time. All in all I believe the Euro seems to have the best handle on the storm and I do expect the GFS to catch up sometime within the next 48 hours.
