According to the latest radar, the northern boundary of the snow has stalled over central NJ, between Philadelphia, Trenton and Atlantic City. Those areas could end up with potentially 20-25 inches of snow tonight, as this band of snow continues to dump heavy snow in that region without moving.
On the other hand, this might spell trouble for my forecast in northern NJ. If the snow band starts to move north again, then we’re still in the game for 3 to 6 inches. But if it continues to remain in central NJ without moving anywhere, then my forecast totals north of central NJ could end up being significantly lowered, with the totals south of that point being raised to 15-25 inches of snow.
