Heavy rain between 5 PM today thru daybreak on 8/13, totaled 3.73". Much of it poured down at the very beginning, with 2.45" measured from 5-7 PM. From today thru 8/18, 6.24" of rain would fall.
Hurricane Connie flooded New York with 7.11" of rain over the course of 39 hours, with the first band of heavy rain moving thru late on 8/11. Although today had the most rain (3.62"), the heaviest sustained period of rain would be tomorrow from 3-9 AM, when 2.50" poured down. Rain was more of an issue than the wind, which gusted between 35-45 mph, well below hurricane force. This was New York's biggest rainstorm since the Great Hurricane of Sept. 1944. And while this ranks as one of New York's biggest rain totals, LaGuardia Airport picked up five inches more rain than Central Park.
Two days after a high of 95°, today's high was only 64° (after a chilly AM low of 57°). The day was also a wet one, as 1.68" of rain fell; this was on top of 0.87" of rain that fell last night.
Although today's spritz of rain in the late afternoon amounted to just 0.01", it was enough to make this the seventh year in a row to have measurable rain on this date.
Three inches of rain fell (3.50", when including rain that fell last night after 11PM). This was New York's greatest 24-hour rain total since 3.54" fell during Hurricane Gloria in late September 1985. At one point 0.43" poured down in just five minutes (1:54-1:59 PM), one inch in fifteen minutes and 1.97" in forty-five minutes (1:45-2:30 PM).
This was the 35th day in a row with high of 80° or warmer, the longest such streak since one of 40 days in 1966.
Today's high was 96°, thirteen degrees hotter than average. This was one of eight days with a high of 96° or hotter in the three-weeks between July 26 and Aug. 14. Tomorrow, with a high of 99°, would be the hottest of these days.
For the the third day in a row the metro area suffered through sauna-like conditions, with each day more uncomfortable than the previous. Today's high of 93°, combined with a dew point at a stifling 78° in the early afternoon, produced a heat index of 105°. For six hours in a row the heat index was 100°+, and the dew point was 74° or higher for 12 hours in a row. The last time the dew point was below 70° was late on 8/9.
Very tropical conditions brought heat (high of 90°), stifling humidity (the dew point reached 77°, producing a heat index around 100°), and then a severe thunderstorm during late afternoon. The 1.76" of rain that poured down (almost all between 4-5 PM) was more than three times the 0.55" that fell last week from tropical storm Isaias.
