Since record-keeping began in Central Park in 1869, September 5 is the date least likely to have reported measurable rain - just 29 times in 153 years (Oct. 4 and Oct. 17 are second, with rain reported in 31 years). Interestingly, the first time rain fell on this date, in 1878, was the most to ever fall on 9/5 - 2.45". After eight years in a row with no rainfall between 2013-2020, a small amount fell in 2021 (0.02").
This was the last day of a six-day heat wave, in which highs ranged from 90° to 93° (and the next two days had highs of 88°). Lows on these six days were between 75° and 79°.
Today was Labor Day and the afternoon high reached 91° - the last Labor Day to have a high in the 90s until 2015 (highs in 1996 and 1998 reached 89°).
Today had temperatures sixteen degrees above average, with a high of 95° (a record) and low of 77°.
After a Labor Day weekend in which every day saw highs in the 82° to 84° range, Tuesday dawned brisk and quite chilly with a low of just 52° (one degree shy of the 1963 record). This was 30 degrees chillier than yesterday's noontime temperature.
This was the eighth year in a row in which no rain fell on Labor Day, the longest such streak since one of ten years between 1958-1967. This was also the mildest three-day Labor Day weekend since 1983, five degrees warmer than average. (Labor Day 2012 would be six degrees above average.)
Today's high in the lows 80s made this just the sixth year to have 100 days with highs of 80° or warmer (2016 would pass 100 as well). And the record of 108 days (set in 1944) was within reach (the record was broken on 9/17).
Today was Labor Day and the high of 84° was the same as 4th of July, and two degrees warmer than Memorial Day. (However, Memorial Day's high was seven degrees above average, today's was five above average and 4th of July's was at the average.) This was just the third year since 1970 in which the three summer holidays had similar highs.
