Today in New York Weather History: September 12



This was the fourth day in a row with a low of 60° and it came one year after another four-day streak of lows at 60° in September (9/4-9/7).  High temperatures on all four days were in the upper 70s.




The first wave of rain associated with a developing hurricane still south of the Bahamas moved through during the afternoon and evening, amounting to 1.64".  More than twice this amount would fall tomorrow as well as the day after that as what became known as The Great Atlantic Hurricane moved up the East coast.


Rain and high winds from hurricane Donna lashed the area during the morning through the first half of the afternoon.  2.36" of rain fell (heaviest between noon and 3 PM) and winds gusted between 40-50 mph; at LaGuardia Airport winds gusted to 90 mph and 3.63" of rain fell.

Today's high was 94°, a record for the date, and the ninth 90-degree high in the past seventeen days (since Aug. 27).  The average high during this two-and-a-half week period was 89°, eleven degrees above average.


This was the ninth day in a row with a low in the 70s, the longest such streak in the month of September.  The average low during these days was 72°, nine degrees above average.




Today was the 12th consecutive day in which the high temperature was 84° or warmer.  This stretch of days was nine degrees warmer than average.  This was also the 27th day in a row with above average mean temperatures, one of the longest such streaks on record. 


0.53" of rain fell in an hour (9:08-10:08 PM).  This downpour occurred shortly after the rain started to fall and continued into the next day.  When the rain ended, 1.89" had been measured.


The 0.39" of rain that fell today between 2-11 PM was the first rain on this date in 21 years.


Scattered showers produced 0.15" of rain, breaking a 17-day dry spell.

also in 2010, just three years earlier, there was another string of dry days in late August to early September of 2007, when no rain fell in the 19 days from 8/22 to 9/9.
