It’s easier for the higher resolution models like the HRRR to correctly resolve our local temperatures on Long Island. The HRRR had 95°+ for the usual North Shore warm spots.

We were lucky that the heat index values didn’t rise to the record levels of 1983, 1993,1995, 1999, 2011, and 2019. https://mesonet.agron.iastate.edu/plotting/auto/?_wait=no&q=155&network=PA_ASOS&zstation=PHL&var=max_feel&threshold=100&hour=12&sdate=0101&edate=1231&month=all&_r=t&dpi=100&_fmt=png

Which is what you would expect with the type of flow pattern that we have been getting. The areas from Somerset County to Newark have been the warmest. Just look at the highs from yesterday with multiple 100s in the corridor. There were at least 6 reported 100° readings yesterday.

That is in a cooler location than Newark.

Very misleading tweet since several locations from Somerset County to Newark have been hitting 100° regularly since July 20th. People should do their research before making statements like that. It’s not that hard to bring up all the other 100° readings at surrounding sites.

The HRRR has 98° north of the LIE right before the sea breeze front arrives this afternoon.

While it took some time to find, this paper explains why the MADIS range test that the Gladstone site uses is so flawed. NYC is a chronically bad type of site mentioned below. The trees covering the ASOS has been an ongoing issue since the 1990s. http://www.thinkmind.org/articles/geoprocessing_2019_1_10_30010.pdf Range tests are not perfect. The record high United States temperature would fail MADIS’s range test, although it would pass MesoW- est’s test. Both MADIS and MesoWest further employ a suite of tests that go beyond their simple range tests. “Bud- dy” tests compare an observation to neighboring observa- tions. MADIS uses Optimal Interpolation in conjunction with cross-validation to measure the conformity of an ob- servation to its neighbors [2]. MesoWest estimates observa- tions using multivariate linear regression [5]. A real obser- vation is compared to the estimate, and if the deviation is high, then the real observation is flagged as questionable. These approaches are flawed in that they do not account for bad metadata, such as incorrect timestamps or incorrect locations. They do not account for chronically bad sites which produce bad data including data that may sometimes appear correct. Of even greater concern, they may not do a good job in assessing accuracy and may be incorrectly la- beling bad data as good and good data as bad. The consequences of ignoring data quality are great. How can we trust our applications and models if the inputs are bad? In turn, how can we better assess data for quality so that we can be confident in its use? In this paper, we present new evaluation results for our previously-published method including evaluation with several new data sets. These results are significant in that they demonstrate the challenges of evaluation of methods for data quality assessment of spatio-temporal weather sen- sor data. The rest of this paper is organized as follows: Sec- tion II presents relevant literature, Section III identifies general challenges, Section IV defines our approach,

The deep westerly flow took the 100° temperarures right down to Long Beach that month.

The longest 100° day streak on Long Island was 4 days in July 2010 at Mineola. The high of 108° was also the highest recorded temperature that I could find for Long Island. Wantagh came close but missed the 4 day steak with one day only making it to 99°. Wantagh reached 107° which was the 2nd highest tempersrure thst I could find for Long Island.

You aren’t going to get that kind of IMBY resolution from a satellite map. But most of Suffolk south of the LIE has had very little rain this month.

Today looks like the peak of the heatwave with Newark making a run on a record breaking 102°. It will also be the first time that Newark had a 5 day 100° heatwave.

The driest parts of Central NJ this month also has the least snow last winter.

Newark is tied with 2011 for the warmest July. It’s the 3rd warmest July in Somerset County NJ. Philly is in 4th place for warmest July. The heat also extends into our northern suburbs.

That 84.4 looks like an error to me in the saved file on the website. I don’t remember seeing that buoy go warmer than 79° to 81°. It would be helpful if there was a saved regional weather round up for that day out of OKX with the actual buoy reports.

The 79°to 80° SSTs at the buoys south of Long Island are near all-time record highs. https://forecast.weather.gov/product.php?site=NWS&issuedby=OKX&product=RWR&format=txt&version=1&glossary=1&highlight=off STATION/POSITION TIME SKY/WX TEMP AIR SEA (UTC) (F) NY Harb Entrance 2150 80 20 S Fire Island 2150 79

June was certainly cooler for many parts of the area than last year. But July is proving to be one of the warmest in several spots. White Plains is currently at the 7th warmest July and climbing. But the consolation prize for your area is it’s still cooler than many other parts of the area on an absolute basis. But relative to the means, it’s still warm by White Plains historical standards for July.

Maybe you are just getting used to the warmer temperatures around White Plains. Plus it’s usually cooler than other parts of our area. White Plains is currently having one of its longest streaks with low temperatures remaining above 70°. The high of 97° a few days ago was the 5th warmest for July and highest since 2012. The hourly dewpoint of 78° a few days ago was the 5th highest for July. So while your temperatures are more tolerable than other parts of the region, they have been rising just like every other spot over the years.

White Plains in rural Westchester has been having more impressive daily low temperatures than LGA relative to the means. White Plains is making a run on 10 consecutive lows over 70°. The last time it did that was 2013. A similar benchmark at LGA would be 10 consecutive days with a low over 75°.
