This is always the story with big storms, they never are a lock up until 36-48 hours before a event. The reasoning is the models need to sort out a lot of variables. The difference between 2 feet and 2 inches in NYC literally is a pin prick when it comes to how energy is handled. It all comes down to trends. At this time a trend has started south, however, we are still over 3 days way. This means things can also flip back north. As a forecaster you need to anticipate how things will change not where they currently are. You base this on how the atmosphere is set up. At this time I believe the whole tri-state area is still in play. My snowfall map factors all of this in. If necessary I will update this.
The next 24 hours are key. Will the southern trends continue? Only mother nature knows.
