The GFS picked up a trend in the last few runs and is sticking to it's guns, the model tends to do this more often than not and in recent times has been spot on. This is not a downgrade just merely a change still gonna be very cold but not the snowmagedon that was predicted for Eastern areas over the last few days.
That's why when people have been saying this Easterly is nailed no way not at 120hrs, 120+ hrs in my eyes is FI in these situations!!
