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!

FPizz Posted July 17 Share Posted July 17 1 hour ago, TheClimateChanger said: 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.

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°.

Nice in the nations mid-section though! 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 Posted July 17 Share Posted July 17 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. 1 Link to comment Share on other sites More sharing options...

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. 1 Link to comment Share on other sites More sharing options...

hooralph Posted July 17 Share Posted July 17 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. https://www.thecity.nyc/2023/07/26/heat-island-hot-map-temperature/ 3 Link to comment Share on other sites More sharing options...

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.

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. The downtown areas of Manhattan are cooler on a south wind off the Harbor. Midtown and Central Park are the warmest parts of the city since they are away from the water. The old NWS office near the Battery would always run cooler than Central Park. The Manhattan moseonet sites with in a few miles of the park were 98° yesterday. This is why Central Park was always warmer than LGA before the ASOS set up in 1995. The NJ mesonet does a great job measuring temperatures in park-like settings like New Brunswick. The sensor isn’t under the trees and the sensor with the radiation shield is out in the sun. Shift that sensor into the nearby wooded area under the trees like the newer location in Central Park and the temperature would be 3 to sometimes 5 degrees cooler. This is why temperatures were never officially measured underneath trees. In a wet pattern enhanced transpiration can have an even greater cooling effect. The issue in Central Park isn’t that it’s a park, it’s that the old site was out in the open and not underneath the trees. So on major 95°+ days before the 90s it was 3° to 5° warmer than it is now. It’s strictly a change in how they measure the temperature and not whether it’s a park or airport. Trying to compare the warm season high and data to before the change in 1995 is like comparing apples to oranges. Also the rain gauge is under the trees and errors in rainfall and rates occur. This is why they NWS tells their observers not to measure rainfall or temperature under trees at their official COOP sites. Plus the reason the highest Central Park wind gust in 1974 hasn’t been exceeded is the trees are growing around it reducing the wind measurement accuracy. So the Central Park temperature yesterday was at least 4° too low. 28th St. / Chelsea 98 3 1 Link to comment Share on other sites More sharing options...
