From the Sunday NWS briefing;
"There is still some uncertainty in these amounts. Similar to what happened in the January 26-27 blizzard, there will be a tight snowfall gradient to the west and northwest of the storm so any seemingly minor shift in the track will either increase (if the low tracks closer to the coast) or decrease (if the low tracks farther offshore) snowfall amounts by several inches across the area (compared to our current forecast). "
Another storm projected for the coming weekend.
