If the NWS really wanted, can't they just trim back everything that is growing directly over the enclosure? It's better than nothing. 

They don't have to tell anybody.  Perhaps a group of us can go in there, with a ladder, with nobody suspecting anything?

Historical:

 

1865: A tornado touched down in Philadelphia around 6 PM ET, killing one person and injuring 15 others. There was a considerable destruction of property, with 23 houses blown down, damage to the Reading Railroad depot, with the water tank, carried 150 yards. Fairmont Park was damaged to the amount of $20,000. 

 

1934: A tremendous dust storm affected the Plains as the Dust Bowl era was in full swing. According to The New York Times, dust "lodged itself in the eyes and throats of weeping and coughing New Yorkers," and even ships some 300 miles offshore sawdust collect on their decks.

 

1945: On May 10th and 11th 10.0 inches or more of snow fell over interior Massachusetts and the lowest barometric pressure for the month of May was recorded at 29.09 inches of mercury.

 

1951: Baltimore, MD recorded their latest snowfall on record with a trace.

1953 - A tornado hit Waco, TX, killing 114 persons and burying some downtown streets under five feet of fallen bricks. (The Weather Channel)

1966 - The 1.6 inch snow at Chicago, IL, was their latest measurable snow of record. Previously the record was 3.7 inches on the 1st and 2nd of May set in 1940. (The Weather Channel)

1970 - A very powerful tornado struck the city of Lubbock, TX, killing 26 persons, injuring more than 500 others, and causing 135 million dollars damage. It was the most destructive tornado of record up until that time, and came on the 17th anniversary of the twister which struck Waco TX killing 114 persons. A second tornado killed two others persons in Lubbock, and the two tornadoes damaged or destroyed nearly a quarter of the city. (David Ludlum) (The Weather Channel)

1987 - Early morning thunderstorms produced up to four inches of rain in southern Texas, with flooding reported from Maverick County to Eagle Pass. Evening thunderstorms in northern Illinois produced golf ball size hail and wind gusts to 70 mph. (Storm Data) (The National Weather Summary)

1988 - Unseasonably warm weather prevailed in the southwestern U.S. Reno, NV, reported a record high of 89 degrees. (The National Weather Summary)

1989 - Afternoon and evening thunderstorms produced severe weather in the High Plains Region. Thunderstorm winds gusted to 71 mph at Gillette WY, and baseball size hail was reported at Pecos TX and Fort Stockton TX. Fort Stockton TX was deluged with 7.75 inches of rain in less than two hours. (The National Weather Summary) (Storm Data)

1990 - Unseasonably cold weather followed in the wake of a spring storm in the north central U.S. Seven cities reported record low temperatures for the date, including Madison WI with a reading of 29 degrees. Thunderstorms produced severe weather in Kansas, Oklahoma and the northern half of Texas. Severe thunderstorms spawned four tornadoes in Texas, and produced high winds which overturned four mobile homes northwest of Abilene TX injuring ten persons. (The National Weather Summary) (Storm Data)

2005 - Strong thunderstorms affected parts of the U.S. Great Plains. In the Hastings, Nebraska area, significant severe weather occurred, including very large hail, damaging winds and widespread flooding. Radar estimated rainfall accumulation locally exceeded 10 inches.

How many 90 degree days did NYC and JFK have in 2022? That 49 number for Newark seems rather high and doesn't fit the profile of the other summers around it which were hotter.

1983, 1991, 1993, 2010 were all much hotter summers.

 

That was the summer west of the Hudson had many more 90 degree days.  Many spots in NJ exceeded EWR numbers,

to be fair our last really hot summer was 2013, Newark is notorious for having a hot bias.

Is this the same low coming back again and again? How long does it take for this thing to dissipate?

 

August of 2013 was cooler and wet.  it did have the massive Western Atlantic Ridge expansion and linking with the rockies ridge in July for the massive heat dome but 2018,2019, 2022 all warmer/hotter for sustained periods

I dont mean to rain on the foliage parade, but the outlier isnt CPK…it is LGA…by far

 

EWR…19% increase

LGA…53% increase

CPK…13% increase

 

The LaGuardia number is way out of whack with the other two. Central Park may be a little low. but the LaGuardia number and what’s going on out there is highly suspect in being accurate.

When you look at the regional increase in 90 days, NYC is the only outlier. LGA has seen a slower increase in 90° days than New Brunswick which is in a more rural to suburban type setting with grass and nearby trees. 

The base period that I am using for comparison is 1961-1990. This is the base period many of us grew up in before the summers and other seasons began to rapidly warm. So it was the last time we had anything approximating a stable climate. 

Summer warming especially accelerated from 2010 to 2024. 12 out of those 15 summers were above normal warmth to record warmth across the area. We only had 3 summers near to slightly below average temperatures in 2014, 2017, and 2023. The last time we had an actual cool summer was back in 2009. 

NYC has only seen an increase of 5.5% in the number of 90° days. Newark is at a 43.5% increase. LGA has increased 78.5%. New Brunswick has jumped 93.7%. POU to our north has seen a 50% increase. So NYC is the obvious outlier. LGA has been subject to cooling breezes off the water in recent summers since the ASOS is right on the water. There have been several more 90° days to the south closer to Corona, Queens. Newark has also had several summers recently with more onshore flow. This is why areas to the west have seen more 90° days. 

If the NYC ASOS wasn’t moved into the shade back in 1995, then the average would be at around 29 days reaching a year now vs 19. So this does a big disservice to residents living in Manhattan where the number of 90° days has been getting undercounted. I arrived at 29 days since this represents around a 60% increase when the Newark and LGA rate of increase is averaged out. So this is what the actual NYC annual number of 90° days would be closer to if the measurements were taken in a clearing like the Great Lawn rather than in a dense area of vegetation under a tall stand of cool shade trees.

 

1961 -1990  to 2010-2024 change in 90° days

NYC….18 to 19……..+5.5%

EWR….23 to 33……..+43.5%

LGA…..14 to 25……..+78.5%

NBW….16 to 31……..+93.7%…….My abbreviation for New Brunswick

POU…..14 to 21……..+50%

No thread yet... if ever, but MLB games in Cleveland, Atlanta, Philly, NY I expect will see delays or cancels into D-N double headers this coming Monday-Thursday, possibly Fri and the weekend.  Most of the delays-cancels should be Tue-Wed, as a start for my own expectations. I apologize if this duplicates someone else's post.  

Trends for the axis max rainfall may shift north as it has been the past couple of days.

The same was the case in August 2011 too.  It really was July when the heat peaked and did so in a historic way (In July 2011 especially.)

all stadiums should have removable domes at this point, with all the money the Yankees have I can't imagine why they'd skimp on a 150 million dollar add-on.

Tony, this must have been the day the historic summers of 1953 and 1993 got started!

On the flip side it's funny to see such cold this late in 1966 when that became our hottest summer on record until 1993 and 2010 came along!

77 today

[donsutherland1]

Under bright sunshine, the mercury rose into the middle and upper 70s across the New York City area. Newark topped out at 81°.

Tomorrow through much of Tuesday will be dry and pleasant days. Temperatures will generally top out in the lower 70s. Showers and/or thundershowers are possible Tuesday night into Wednesday. It will turn somewhat warmer on Thursday and the week could end with temperatures in the upper 70s to perhaps 80°.

Meanwhile, parts of Texas will see extreme heat. The temperature could approach or set new May monthly high temperature records in such cities as Austin, Del Rio and San Antonio.

The extended guidance has grown cooler for the second half of May than it had been. Both the CFSv2 and ECMWF weekly guidance are now in good agreement that the second half of the month could average near normal overall.

The ENSO Region 1+2 anomaly was +0.1°C and the Region 3.4 anomaly was -0.1°C for the week centered around April 30. For the past six weeks, the ENSO Region 1+2 anomaly has averaged +0.68°C and the ENSO Region 3.4 anomaly has averaged -0.05°C. Neutral ENSO conditions will likely continue through at least early summer.

Early indications are that summer 2025 will be warmer than normal in the New York City and Philadelphia areas. The potential exists for a much warmer than normal summer (more than 1° above normal).

The SOI was -11.85 today.

The preliminary Arctic Oscillation (AO) was +1.173 today.

Based on sensitivity analysis applied to the latest guidance, there is an implied near 76% probability that New York City will have a warmer than normal May (1991-2020 normal). May will likely finish with a mean temperature near 65.7° (2.5° above normal).

Union wage, etc.,closer to a billion.  NYC building costs are astronomical compared to the rest of the country.  I forget the difference of the cost of Citifield being built with a dome vs. no dome, but it was quite large.  It would cost $800 million to put one on now...

You'd also have to wait for a five year environmental impact study on how the dome impacts the breeding habits of the tiger mosquito in the nearby estuary.

Bust on high temps today? I thought we were supposed to be around 75 as of last night's forecast?

On another note, it seems Central Park is going to be totally irrelevant for the foreseeable future.

The issue gets worse and worse. Wait until the first heatwave and it’s 92+ at every station but 89 at the Park and the media reports 89. It’s a big pet peeve of mine because it’s not the reality of the experience of the everyday person.
