The Central Park data is flawed due to the sensor being blocked by trees and foliage from sunlight and open airflow. Not because it’s located in a park. The open areas of the park  are probably 1-3 degrees warmer for highs than the sensor area that is blocked. The old sensor was in an open area before 1996 with no obstructions. This is why NYC has an artificial 90 degree day cooling trend with more 90 degree days in 1991 and 1993 than 2010.

Place sensors at a horizontal distance of 2 times the height of the nearest object (tree,
structure, etc). [Example: 40 feet away from a 20 foot tall tree].

I wish I could bookmark this post, I get sick of having to explain this to people outside of this board.

Central Park’s “cooling trend” is a go to for those in denial of climate change, they then blame warming trends elsewhere on airport runways.

central park has been on a warming trend for years...this decade could end up with the most 90+ days despite to much foliage...three of the last four years had at least 20 or more 90 degree days...the last time that happened was in the 1950's...

90 degrees days......

Unusual pattern coming up. The 12z Euro gets the tropical system stuck under the building heat ridge. It crawls for days over the Central US dumping torrential rains. Acts as a heat and humidity pump for us with a deep SW flow.Temperatures in the 90’s with dewpoints in the 70’s will result in very high heat indices. Some hints at beneficial rains for us near the end of the 10 day period with the tropical remnants.

Yeah. I have noticed that we are always finding some sort of way for high dew points. Why is that?

Warmer atmosphere holds more moisture. It will be interesting to see if the tropical remnants get surrounded by +20C 850 temperatures.

Same here, 87.4F. Probably would have made 89-90F, but for the Canadian smoke.

Low was 60.6F this morning. 

Not sure what my High and Low was for the day, not far off from Syosset readings I’m sure.  Today was pretty close to a prefect summer day.   Cool morning, sunny day(save for some haze)warm afternoon and now cooling off nicely, albeit slowly.  And a dry day, low humidity.

Yep, John posted on this.  Wonder if it keeps temps down just a tad today due to it. 

 

On my drive today up Rt 17 and ultimately to the central Fingerlakes the smoke density varied significantly. In some spots it was crystally clear and others it was quite the opposite.

Pumping that kind of heat up here where is the opposite occurring in the hemisphere? I think of these things as "balancers" regulating hemispheric temps so if we are pumping heat north somewhere is dumping cold south.

Next 8 days averaging 80degs., or 3.5degs. AN.

July is looking like a shoe-in for TTen, which is +3.1, especially with the heat that may come Week 3.   Meanwhile analogs put Aug. at Normal and Sept.-Oct. BN.    In fact a snowy Week 2 in Oct. looks doable.   Our earliest Trace of Snow is Oct. 10.   Seems 20 degs. BN on at least one day might happen.

Last summer extended to about Oct. 10, (my preference) but unlikely for this summer att.

74.4* here at 6am.    77.0* by 8am.    81.8* by 11am, but with al ot of cumulus clouds.   86.0* by 1pm, still clouds, humidity is low.

I am hoping that the Euro is correct about the heavy rain potential Thursday night. We can really use the rain. Almost looks like a wannabe PRE with the tropical development in the Gulf. Not sure if the features are close enough to technically be called a PRE. But any rain after the dry last few weeks would be welcome.

Absolutely! When it doesn’t rain my job becomes ten times harder. I have dozens of planters on campus that require hand watering. And huge terraces that were designed (without my input) an irrigation system. I wish I could posts pics but it always says attachments full.

That heat potential next week is awful. I had a feeling sooner or later we would get some real heat. And moving forward that 110 degree day will eventually happen...

This weather is decent if you’re at the beach or next to the pool otherwise it’s stay at home with the AC blasting. September can’t come early enough but those nights are getting longer already so sooner than later the hot air will diminish!

Summer just started, I’m not going by the calendar, only by the temps.  Let’s not rush the inevitable decline into fall and winter weather.  Enjoy the outdoors!

We don't need the rain at all
