Heavy rain fell briefly, but given its forward speed, totals were not heavy. By the time it crossed the Delaware River into NJ shortly after noon it was a bona fide derecho, defined by its over 250 mile path, at least 50 mile width, rapid forward speed, and wind gusts exceeding 58 mph over most of its length. Meanwhile, a squall line in northwestern Pennsylvania began to race across the Keystone State with an impressive forward speed of close to 60 mph. The remainder of the morning was quiet across the Garden State. Rainfall from approximately 7AM on June 2nd to 7AM on the 3rd (left) and from 7AM on June 3rd to 7AM on June 4th (right).

Other high achievers were two sites in Manchester Township (Ocean) with 6.86” and 6.46”, two in Washington Township (Gloucester) at 6.68” and 6.56”, and three in Brick Township (Ocean) at 6.56”, 6.40”, and 6.17”. Two stations in Wall Township (Monmouth) received 7.45” and 7.26”, and Sewell (Gloucester) saw 7.44”. Putting some specific numbers on the monthly precipitation distribution mentioned in the previous section, a Lakewood (Ocean County) CoCoRaHS station received 7.77”, the most in the state. There were 13 events during the month where one or more inches of rain fell at a CoCoRaHS or NJWxNet station, yet few had a broad coverage of heavy rain across NJ. The 15 warmest Junes across NJ since 1895. This ranks as the 10th warmest, joining four other years this century in the top 10, while being the warmest since 2011 (Table 1).

The Highlands, portions of central NJ, and southern Ocean and Cape May counties saw as little as 1.00–2.00”.įigure 1. Monmouth and northern Ocean counties saw the most, totaling over 5.00” in spots, with a secondary maximum in Gloucester County. As is typical during the warm season, where the bulk of the rainfall is provided by showers and thunderstorms, totals varied widely from location to location, even at times in close proximity to one another (Figure 1).
