Chris we had some in the humid summer of 1996 too, but the temps weren't as high as 1995.  I remember we had either 81/81 or 82/82 one day.  Might've happened again in August 2001.

Yeah, doesn't look like we'll be able to get close to the record set last August.

If you live in the Northeast, you know it has been a hot week with tropical amounts of humidity that made it feel even more miserable as soon as you stepped outdoors.

In one location, the uncomfortable humidity stuck around for a record amount of time. JFK Airport in New York City broke the record for most consecutive hours of a dew point of 70 degrees Fahrenheit or higher Wednesday morning.

The dew point, or measure of the amount of water vapor in the atmosphere, rose above 70 degrees at 8 p.m. EDT on Aug. 9. It remained at or above 70 degrees until 11 a.m. EDT Aug. 17, when it dropped to 66 degrees.

 

The previous record was 178 consecutive hours in August 2003, according to Alaskan climatologist Brian Brettschneider.

It is quite remarkable for a city at 40.7 degrees latitude to spend over a week socked into such an oppressively humid air mass; daily dew points in the 70s are typically found in the Deep South in the summer.

An 84-degree dew point was measured at JFK Airport Saturday afternoon, sending the heat index up to a searing 112 degrees.

Wow that was just last summer? I remember it was a humid summer but not that humid.  What was the high temp with that 84 DP and 112 HI?

Next 8 days down to +3degs.  (Avg. 73).  By morning of 27th  we should be just slightly positive for the month.

However, we may be more concerned about wind, tides and rain, since CMC still has tropical storm conditions here for an entire day,  at that time, albeit from a moribund storm.

That was on 8-13-16 during the extended 75 degree day dewpoint streak.

I do not know which swirl gives rise to this storm that the GDPS keeps showing.   This time the beast gives up the ghost right over us.

As usual the CMC has a bunch of spinning tops, (PresLevel @144hrs) probably not possible, which look more like a computer game.
