Strong to high winds occurred across New Jersey from the middle of the evening on the 30th into the early afternoon of the 31st in New Jersey. Peak wind gusts reached between 45 mph and 65 mph and downed weak trees, tree limbs and power lines and caused power outages. Approximately 20,000 homes and businesses lost power. The wind damage was exacerbated by isolated severe thunderstorms that moved through the central part of the state during the early morning on the 31st. All of the high winds and most of the highest wind gusts occurred in the south to southwest flow preceding a cold frontal passage during the early morning on the 31st. However, strong wind gusts near 50 mph continued in the westerly flow following the cold frontal passage during the morning and into early afternoon on the 31st. The cold front moved through the state between 5 a.m. EST and 7 a.m. EST on the 31st.
PSE&G reported about 11,000 outages across New Jersey, 3,400 of them in Burlington County. Power was expected to be fully restored later in the day on the 31st.

Outages were reported in Freehold, Upper Freehold and Millstone. In Middletown, downed power lines led to a blown transformer. In Ocean County, power outages were reported in Lakewood, Berkeley, Manchester, Plumsted and Lacey Townships. Uprooted trees were reported in Toms River.

The central pressure of the low pressure system over Illinois deepened from 992 millibars at 7 a.m. EST on the 30th to 968 millibars at 7 a.m. EST on the 31st when it was in Quebec Province. The low pressure system continued to deepen and the following morning, the pressure was 944 millibars as it was crossing the Labrador Sea (The lowest analyzed pressure with this system was 940 millibars.). The rapid deepening of the surface low intensified the southerly flow preceding its cold front and then the pressure gradient (difference) between the low pressure system and a high pressure system entering the Northern Plains continued strong winds into the afternoon of the 31st. The low pressure system moved far enough away from New Jersey for the strong winds to cease later that day.
