The high in Long Beach might’ve made it to 75 today before the S wind really kicked in. Takes a really strong W flow this time of year to keep the seabreeze away. I don’t miss spring down there with the daily Ambrose Jet one second. 

I remember in April 2010 I think JFK just barely missed 90 (89) while you were languishing in the upper 60s down there lol.  It even got into the upper 80s here.

NYC records today include max 90F (former record 88F 1977) and min 67F (former record 61F 1945, it was 60F in 1977 and 2018). 

NYC has now set more daily records than most recent years at this stage, and is on pace to finish in the top ten of records held (I had a post earlier listing the top contenders for that). The count so far is 2.83 record highs and 2.33 record high minima. The records for surviving records now on the books are 9.17 record high maxima (2001) and 12.92 record high minima (2015). 2017 was a bit higher than 2015 for record high minima until 2023 took a half share away yesterday (it was 13.17 and is now 12.67). 2015 has already lost 2.0 from the 14.92 count it had at end of its run. 

Are we close to the pace we set in 2010?

So glad NYC hit 90 degrees!  It was close!  Interesting that LGA missed by 1 degree and on a land breeze day JFK missed by 5 degrees!

Don do you have stats on that day in April 2010 when we had our earliest 90 degree day?  NYC hit 92 and if I remember correctly JFK got to 89?  So that was hotter than today and about a week earlier?  Did EWR and LGA also hit 92 that day?

On April 7, 2010, JFK reached 87, LGA reached 91, and Central Park hit 92.

I'll pass on mid summer weather in April. The humidity makes it tolerable but it's still way too warm.

Before I answer that, please note, the post you quoted was edited later and the number of records so far in 2023 should read 2.83 high maxima and 4.33 high minima (it was reading 2.33 high minima), So if today also sets records the count might be 3.83 and 5.33. Those are both ahead of the pace for breaking 9.17 (2001) and 12.92 (2015) which are the highest numbers of held records for any years (both of those were two higher after the years ended so they have lost or tied a few records to reduce the count). As for 2010, its count was 3,5 for high maxima and 4.25 for high minima so not a particularly high yield for recent years, 2000 has held on to all the count that it had for high maxima and lost one record high minimum to 2011, as well as seeing a one-third share of another reduced to a quarter when 2015 piled on. So its count was 5.33 at the end of 2010, and is now 4.25. 

If there was no warming trend or urban heat island you would expect each year to retain about 2 of each of these records but the average is closer to 5 in recent decades (and the earlier years especially before 1910 have lost most of the ones they had). So 2010 is only about middle of the pack for retained record highs of either kind. It is similar to the past four (2019, 2020, 2021, 2022). 2017 and 2018 were more productive. 

This is the number of records held by every year since 1990 ... actually the count adjusted for ties, the number of records including ties would be a bit higher.

Down to 57 and already up to 68.  More clouds than yesterday but more mid/upper 80s and some isolated 90s in the CNJ-NE-NJ /MYC metro corridor, unless more clouds get in the way later during the afternoon.  Cloudy wet weekend (showers) as Gulf systems pushes up the EC.  Mon (4/17) looks a bit wetter as front slows throughs the area and much cooler Mon (4/17) - Tue (4/18).  Warm back up by Wed (4/19) with building support for a 2 day stronger warmth by Thu (4/20) and Fri (4/21).  Back and forth but overall bias warm the last 10 days of the month.

Historical:

1873 - A famous Easter blizzard raged across Kansas, Nebraska and South Dakota. Gale force winds blew the wet snow into massive drifts, however there were few deaths due to the sparse population and due to the gradual increase of the storm. (David Ludlum)

1886 - A devastating tornado, 800 yards in width at times, cut a twenty mile path through Saint Cloud MN killing 74 persons. The bottom of the Mississippi River was said to have been seen during the tornado's crossing. Eleven persons were killed at a wedding party near the town of Rice. (David Ludlum) (The Weather Channel)

 

1912: On her maiden voyage, the RMS Titanic rammed into an iceberg just before midnight. The "unsinkable ship" sank two hours and forty minutes later into the icy water of the Atlantic Ocean near Newfoundland, Canada. Tragically, 1,517 passengers including the crew were lost. A nearby ship, the Carpathia, rushed to the Titanic and was able to save 706 people. 

1922: The Mississippi River reached a record height of 21.3 feet at New Orleans, Louisiana, and the river was still rising, with the crest still a week away. Understandably, the City of New Orleans was nervous as reports of levees failing upriver reached the city. A crevasse below New Orleans would relieve the pressure on the town's strained levees on the 27th, spared the city from disaster.

 

1935: Black Sunday refers to a particularly severe dust storm that occurred on April 14, 1935, as part of the Dust Bowl. During the afternoon, the residents of the Plains States were forced to take cover as a dust storm, or "black blizzard," blew through the region. The storm hit the Oklahoma Panhandle and Northwestern Oklahoma first and moved south for the remainder of the day. It hit Beaver around 4:00 p.m., Boise City around 5:15 p.m., and Amarillo, Texas, at 7:20 p.m. The conditions were the most severe in the Oklahoma and Texas panhandles, but the storm's effects were felt in other surrounding areas.
 

1987 - A storm system moving slowly northeastward across the Middle Mississippi Valley produced severe thunderstorms which spawned three tornadoes around Ottumwa IA, and produced up to four inches of rain in southeastern Nebraska, flooding rivers and streams. (The National Weather Summary) (Storm Data)

1988 - A weather disturbance off the southern coast of California brought parts of southern California their first rain in six weeks. Rain-slickened roads resulted in numerous accidents in southern California, including a ten car pile-up at Riverside. (The National Weather Summary) (Storm Data)

1989 - Late afternoon thunderstorms in northern Florida soaked the town of Golden Gate with 4.37 inches of rain in about two hours, resulting in local flooding. (The National Weather Summary) (Storm Data)

1990 - Thunderstorms developing along a cold front produced severe weather in southeastern Texas during the mid morning hours. Thunderstorms produced dime size hail at Galveston, and wind gusts to 59 mph at Port Arthur. Afternoon thunderstorms over southeast Louisiana spawned tornadoes south of Bogalusa and at Rio. (Storm Data)

I wonder if our area has ever had a day where it started below freezing and ended up in the 90s?

I don’t think so.The closest NYC came was within 5 days during April 1976. Walpack did it within 2 days this week. Have to go out West for 90° days that start below freezing.

Only around 60 on the barrier islands. Low to mid 60s in Long Beach. Let’s see today how fast that sea breeze boundary can progress inland. World of difference from here where it’s 84. Huge split between Long Beach where it’s 62-63 and Oceanside/Baldwin where it’s 82-83. That’s a 10-15 minute drive.

In the NYC records, the earliest minimum of 70+ was 74F on April 17, 2002. A value of 70F on April 18, 1976 was broken by 76F on April 18th, 2002. These are the only three minima at NYC in the 70s in April. The closest to them would be the 69F records for April 16, 2002 and Apr 28, 1990 and 2009. There were 70+ minima May 3-4 2018 (70F, 72F) and the latter of those broke a record of 71F from May 4, 2001,  but in terms of an early 70+ reading before 1976, that would be 71F on May 6, 1930.

Yeah, NYC used to warmer than LGA during the summer in the 70s and earlier before the excess tree growth.

 

https://www.nytimes.com/1977/07/22/archives/vandals-in-central-park-forcing-weather-service-to-seek-new-site.html

Harold Gibson, the meteorologist in charge of the New York bureau, 

 

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.

NYC is the only station with the same number of 90° days in the recent era as the 70s due to tree growth too close to sensor. It used to have more 90° days than LGA and 3 less than EWR. Now it’s 7 fewer days than LGA and 14 lower than Newark.

Close call for 90 at the Park in the next hour or so then high cloudiness begins to stream up from the south as the winds gradually kick around to more southerly. I think it would be the last 90 at the Park for at least 2-3 weeks if they even get there.
