Track shift

It now appears that the storm will track a bit further south than thought yesterday. That allows cold air to drain down from the north and that will change any rain over to snow. The heaviest snow will fall between 1 and 10 AM Monday morning. It will be very heavy and wet, so it will cause some power outages. NE winds will increase to 20-30 MPH with gusts to 45 MPH along the coast after midnight as well.
