July 2024

[SACRUS]

 

79 / 72 clouds left over from overnight storms, slowly clearing. Should continue to the heat for most places before the front comes through later today (front to CPA) so about 4 - 6 hours of sunshine / heating.  Some lingering storms Thu (eastern/coastal areas) otherwise a break in the heat lasting through Sat (7/20).    Strong heat limited but upper 80s / near to low 90s from Sun (7/21) as the Atltantic ridge keeps the EC in the ridge.  Perhaps some stronger heat the MW trough lifts out later next week and weekend.

 

7/17 : Hot /humid (evening storms front)
7/18 - 7/20 : break in heat . humiditity
7/21 - beyond : Overall warm to humid - more frequent storm chances with southerly tropical flow by the 24th

The very wet vegetation at the park limited the high to only 94° yesterday. So we may not see another 100° in Central Park unless a place like Newark makes it to 105°. Since on the very hot days NYC runs about 5° cooler.

Wow! Look at this photo I found on Wikimedia dated May 24, 2024. This is absolutely absurd. Who was the decisionmaker that identified this as an appropriate location to install the ASOS?  It doesn't comply with any siting standards. Most backyard thermometers are more reliably sited than this.

7pm. Storms but no solid line. Some may see little or nothing while others get rocked 

[Poker2015]

Wasn't home to see it, but our pergola was ripped right out of the concrete on the patio and thrown on the lawn.

Glass everywhere from the lights we had hanging from it.

What about Manhattan micro sites from Con Ed?  They 97+ or close to NYC?

Imagine spending all this taxpayer money to install an ASOS in Central Park solely for the purpose of "continuity" and placing it in the location least representative of New York City that you can find, so that there is no reliable continuity in the records. Had to be deliberate.

83 and overcast here, yesterday at this time it was already 95 (with sun).

Look at the rain gauge in the back right.  You have to believe the tree canopy is interfering with that as well.  What a joke.

Well, we are halfway through meteorological Summer.  Won't be long before we are playing kick the "Canadian cold" can.  Hope not but we'll see.

This should be the last of the 100° heat for a while as a big +PNA is set to dominate for the next 10 days.

Trof position might be such that we still run above normal and on the humid side.  Might also give us AN precip.  

Nice in the nations mid-section though!

For every NYC station there are 5 rooftop/tarmac stations that are just as useful

But all of those sites measure the actual temperatures in their respective locations. The NYC station used to be away from the trees in Central Park and was 3 to 5° warmer than now before the ASOS installation under the trees in 1995. So the actual Central Park high temperature yesterday in an open space like the Great Lawn was 98° or 99°.

When the devices at the castle are not functioning, the Weather Service substitutes readings from La Guardia Airport. But Mr. Gibson said those readings do not really reflect conditions in the city, because they may be several degrees cooler in summer or warmer in winter than those in Central Park.

It looks like the pattern will begin to weaken the drought over the Southeast. So maybe the next warm up after this relaxation of major heat will be slightly less intense. We’ll see if wetter conditions over the source region for this recent heatwave can make a difference. 
 

[winterwx21]

Latest HRRR hits us hard here around 8pm. Hoping to see a good storm tonight! 

I'm also looking forward to the nice break in the humidity. Dew points in 50s on Friday will feel great. That looks like one of the nicest days of the summer. Dew points will go up a little over the weekend, but I don't think they'll get back to the 70s until Tuesday. A nice break from the high humidity.

GFS more prominent in building the Atlantic ridge in 7/24 - 26 with 500 MB height >594DM.  That should setup some stronger humidity  / heat potential.  Looks overall warm-hot and humid with more frequent rain chances.  Some of that heat building in the southwest may come east in spurts beyond the end of next week / 29th.

[lee59]

My highs on the 14th 91.3, the 15th 89.5 and the 16th 93.4. That is my first official heatwave of the season if you round up the 89.5.

Manhattan microsites back up Central Park temp since winds were out of S mostly yesterday. Need that due W wind for the heat. 

[hooralph]

Forgive me if this was shared previously; relevant to the CPK discussion and the summer in general. Very localized heat island map. 

I was gratified to find I live by that “cooler” tongue on the UWS; I suspect the streets (esp the wide ones : 106 and 110) providing more of a channel for upsloping winds.

I assume that these departures are specific to the summer given how the sun roasts everything? It would be interesting to see the winter version.

Why though?  I mean I get that wind direction matters as it does everywhere, but why doesn't the tree canopy that everyone bitches about every single day here care about west winds?  Does it blow the canopy open all of sudden?  The canopy should effect the site no matter what, but on west wind days NYC is sometimes the highest temp.  Maybe the tree canopy is overstated and it is really more about the winds.  I have noticed that some of the personal sites near NYC often match the temp, and I'm sure those aren't under trees, but that fact often gets ignored.
