In addition to the blizzard conditions, heavy snow managed to lift into parts of southern New Hampshire. The heaviest snowfall was on the morning of the 23rd into the early afternoon before tapering off. Snowfall totals ranged from 5 to 9 inches.

Low pressure began to develop over the Southeast on the morning of the 22nd. By the evening it had moved to a position off the Carolinas and was deepening rapidly. Between 7 pm on the 22nd and 7 am on the 23rd, central pressure in the storm dropped from 991 mb to 966 mb. The intense low pressure combined with high pressure around 1045 mb building into Quebec to produce a strong pressure gradient across the region. The result was strong wind gusts through much of the day on the 23rd.
