Today was the 25th, and last day, this summer with a high of 90° or hotter. All but one of the readings occurred in July and August. Although there have been 16 summers with more days in the 90s/100s, 1955 has the distinction of having the most days with highs of 95°+, sixteen. (Today's high, however, was 90°.)
Today was the 15th day of the past seventeen to have highs of 85° or warmer. The average high during these days was 87.4°, five degrees warmer than average.
Although April 18 had the year's hottest high temperature (96°), today, with a high/low of 94°/74°, had the year's highest mean temperature - 84.0°. (On 4/18 the low was 70°.)
For the 16th year in a row, no rain fell on this date. Additionally, this morning's low of 60° was the coolest reading of the month.
Rain that began yesterday during the late afternoon continued for the entire day today, and amounted to 3.02" (1.85" fell today on top of yesterday's 1.17"). This was New York's biggest rainstorm since last August, when 3.20" fell on the 16th and 17th. It was also the first time rain fell on this date since 1977 (when 1.22" fell).
Today's high was 90°, the eighth, and last, 90-degree day of the year (a typical year has eighteen).
Today was the sixth day this month with a low in the 50s, tying August 1989 for the most morning lows in the 50s during August (going back to 1970).
0.40" of rain fell between 3-4 AM, and 0.74" in total. A lot more rain fell in New Jersey and areas north of Westchester County.
It was dreary and humid, with a number of heavy downpours during the afternoon and evening that amounted to 1.69". (Half of the rain came down in a 90-minute period from 8-9:30 PM). This was the rainiest day since the end of March.
After two weeks of oppressive conditions, relief arrived overnight, and the daytime hours had pleasant temperatures (upper 70s), and low humidity, under clear skies. The day's high/low of 79°/69° ended three streaks: a 16-day streak of lows in the 70s, a 19-day streak of high temperatures of 80+, and a 16-day streak with above average mean temperatures (the longest above-average streak since one of 34 days in Dec. 2015 - Jan. 2016).
Today, with a high of 90°, was the sixth day in a row with a high of 87° or hotter, the longest such streak since another one of six days in August 2016 (8/11-16). However, the streak in 2016 was 3.5 degrees hotter (average high of 92.2° vs. 88.7°). Shortly after sundown, the approach of cooler air triggered strong thunderstorms that dropped 1.02" of rain between 8:30 PM and 1AM. (I was at a work-related cocktail party at a rooftop bar that, fortunately, ended shortly after 8:00.)
A second round of heavy rain from tropical storm Henri began shortly after daybreak, as the storm headed to Rhode Island, where it made landfall early this afternoon. Although today’s soaking rain wasn’t torrential, like it was last night (when 4.45” poured down), the 2.67” that fell today was enough to establish a record for the second day in a row. (This followed back-to-back record rainfalls last month, on 7/8 and 7/9). The rain fell heaviest between 2-5 PM, when 1.49" was measured.
The 24-hour rainfall total of 7.04” (between 8 PM yesterday and 8 PM today) was the greatest amount to fall in this amount of time since April 2007, when 7.80” fell between 2AM on 4/15 and 2AM on 4/16. Although Henri produced record rainfall in NYC, one saving grace was that that there were no gusty winds to contend with.
