Tornado damage

Wow, what a month. July 2021 provided a never-ending cascade of weather events, including a tropical storm, a record-tying number of tornadoes, large hail, flash floods, hot days, chilly nights, smoke-filled skies, and on the last day of the month, perhaps the nicest day of the summer. The statewide average precipitation of 7.59” was 2.88” above the 1991–2020 normal and ranked 8th wettest of all Julys back to 1895. It was the wettest July since 1975 and second wettest in almost 50 years. The northern portion of the state averaged 8.16” which was 3.44” above normal. The south averaged 7.36” which was 2.62” above normal.

The average temperature of 75.8° was 0.4° above the 1991–2020 normal, but 1.9° above the 1895–2021 average. This ranked as the 24th warmest July since 1895. 13 of the 25 warmest Julys in the past 127 years have occurred since 2002. The nine July tornadoes is the most in a month since official records began in 1950. Tropical Storm Elsa was the earliest fifth storm of any season on record in the Atlantic basin.

The statewide average precipitation this July was 6.79”. This is 2.22” above the 1981–2010 normal and ranks as the 15th wettest July on record. Looking at the state in quarters from north to south, the northernmost was driest, particularly the northwest. Next came a wet sector, followed by a more average one, with the southernmost quarter the wettest. Few locations received less than 4 inches, while scattered totals of more than 10 inches were found in the two wettest quarters.

Tree on house

After April timidly transitioned into milder weather, May was plenty bold in the thermal department, on multiple occasions behaving more like summer than late spring. Most NJ residents did not seem to mind the warmth; rather, from the second week onward, it was the frequent episodes of rain, often targeting weekends, which raised the level of crankiness among many! Statewide, this was the 5th warmest May since records commenced in 1895. The 65.0° average was 4.5° above the 1981–2010 mean. Five of the ten warmest Mays have occurred since 2004. In most locations, rain fell on at least half of the days of the month. The 5.96” average across NJ was 1.97” above the 1981–2010 mean. This ranks as the 13th wettest May on record, but 0.55” below last year’s average.

Damage from tornado in Paramus

The first week of October was nothing but bizarre, or at least to most New Jerseyeans it seemed that way. The period included unseasonably warm weather, heavy rain, strong winds and even a tornado. It was all credited to a stationary front that held in position in Southern New York, which allowed warm air to enter the Garden State. The warm air was later pushed out, when a sharp and potent cold front from the Midwest set off severe storms and heavy rain in parts of the area.
