The strongest hurricane of the season brought heavy rain when it crossed over the eastern end of Long Island. There were two periods of heavy rain, the first between 6-10 AM, when 1.23" fell, and then much heavier rain fell from 5-11 PM, when 3.26" poured down. (An additional 0.37" fell at other times during the day, bringing the day's total rainfall to 4.86", a record for the date.) During the early evening winds gusted between 45-50 mph.
Today was the 18th day in a row with above average temperatures (half of the days had highs of 89° or hotter). During this stretch temperatures were nearly eight degrees above average.
1.01" of rain fell between 9-11 PM (and 1.55" fell overall).
Today was the end of a five-day stretch in which the temperature averaged 12 degrees above average (high/low of 89°/75°) - including three days in the 90s (hottest reading was 94°.
0.30" of rain fell in a 15-minute period between 8:49-9:04 PM. Overall, 1.25" fell between 1-11 PM.
Heavy rains from tropical storm Frances (amounting to 3.77") flooded the area shortly before morning rush hour (most fell between 5-8 AM, with 1.76" falling between 6-7 AM). Frances' effects were felt here three days after it made landfall as a slow-moving category 2 hurricane along Florida's east coast.
Today was the 37th, and last, day of the year with a high temperature in the 90s - two fewer than 1991's and 1993's record number. (However, 2010's summer was hotter than either of those years.) Since 2010, no year has come close to its number of hot readings (the most has been 25 in 2022).
Over the past three days 5.33" of rain fell from the combination of a cold front and remnants of tropical storm Lee. Since 8/9 Central Park received an incredible 23.16" of rain (normal is 4.32"). During this 31-day period there were four major rainstorms: 2.09" fell on 8/8; 6.37" on 8/14-15; 6.87" on 8/27-28 (from Hurricane Irene) and 5.33" in the last three days. So much rain had fallen thru today that the 55 inches measured in the Park was already five inches above its annual average.
Today continued a pattern of severe thunderstorms that dissipated once they moved over Manhattan. Today's storm arrived between 6:30-7 PM and was the ninth since June 22 to bear down on the City only to weaken once it crossed the Hudson River (however, many suburbs and some of NYC's boroughs were hit hard). One exception was the thunderstorm that struck on July 18 (1.76" fell), which was also the hottest day of the year (100°).
Clear and sizzling hot as the high soared to 97°, twenty degrees above average, and a record for the date. This was the hottest reading of the year and the hottest in September since 1983 (when the mercury reached 99° on 9/11). However, today's mean temperature of 86.5° wasn't the hottest of the summer; that remained on 7/20, when the high/low was 94°/82° (mean temperature of 88°). It would be six years before a reading hotter than this was reached (98° on June 30, 2021).
