The problem with starting a storm thread too early has nothing to Do with superstition. The earlier you start a thread the more chances you have of a major adjustment. 4 days out just leaves too much adjustments in forecast.
We have been down this road before... The best snows are most always north of where the models have them in the overrunning situation... I would not be surprised to see it in south central PA tomorrow.
We are about 12 hours away from first of the storm which is pretty much set in stone. The second is 36 hours away. The second part is where the real uncertainty comes into play.
