The summer of 2019 concluded on a warm and a bit dry note when averaged across the Garden State. The warmth was a common theme throughout June to August, while the earlier summer months were on the wet side. The average August temperature of 74.4° was 1.4° above the 1981–2010 mean and is tied with 1983 and 1973 as the 14th warmest since 1895. On 12 days, the temperature topped out at 90° or hotter at one or more Rutgers NJ Weather Network station, but never exceeded 96°. The heat was somewhat tempered by seven mornings with lows in the 40°s at some northwestern NJWxNet locations.
August precipitation averaged 3.75” across NJ. This was 0.35” below normal and ranks as the 52nd driest of the past 125 Augusts. As expected during a summer month that is dominated by hit and miss showers, rainfall totals varied quite a bit, even on a local scale. The driest location in the state was Lambertville in Hunterdon County where 1.48” fell, while the wettest was Lebanon, also in Hunterdon County, with 7.99”. When and where the storms struck, they were, at times, intense. This included small tornadoes and more widespread strong winds, dangerous lightning, and flash flooding.
