If it holds, both JFK Airport and Newark will have had identical high and low temperatures today (86°-66°). The last time that happened was July 31. Fun fact: The record is 3 consecutive days (February 7-9, 2004).

The funny thing is NYC and LGA bringing up the rear in temperatures.

NYC seems to have the lowest temperatures no matter the wind direction lol.

65 / 44 clear .  Sunny today cooler low - upper 70s in the warmest areas.  A bit cooler tomorrow.  Overall warmer and perhaps a period of rain as another low cuts off under the ridge between Tue - Sat next week.  Will see where it does and which areas get some rains.

 

High clouds coming in tomorrow morning so it won't be as nice as it is today.

I noticed that SST have already started dropping and are in the mid to upper 60s now, even along the Jersey shore?

That's now a fairly common outcome. The combination of site changes in Central Park (overgrowth of trees), increasing urbanization in the vicinity of the LGA/JFK sites (growing heat island, especially at LGA), and more frequent abnormally warm SSTAs off JFK have contributed. The latter two factors are more prominent during the winter months e.g., last winter was a prominent example where JFK had a warm seasonal temperature anomaly while Central Park had a cold one relative to the 1991-2020 baseline. Summer 2025 provides a strong example of the impact of Central Park's trees where Central Park could not reach 100° during the region's hottest June air mass on record.

Mid 70s with the dewpoint in the high 40s and not a cloud in the sky ..... as perfect as it gets today. We'll be going back to summer on Tuesday though with highs in the mid 80s and dewpoints in the mid 60s.

1953: A strong upper level ridge was responsible for record highs across Texas & parts of Arizona. Midland set their all-time September record high with 107°. Other daily record highs included: Phoenix, AZ: 105°-Tied, Wichita Falls, TX: 103°, Dallas, TX: 102°, Dallas (DFW), TX: 102°, San Angelo, TX: 102°, Abilene, TX: 101°-Tied and Waco, TX: 100°-Tied. (Ref. Wilson Wx. History)

1961: Hurricane Esther, a Category 4 storm off of Cape Hatteras, NC began to slow down as it moved north-northeast well off the Jersey shore. The storm continued to weaken as it did a 5 day loop south of Cape Cod, MA then moved across Cape Cod and into Maine on the 26th. (Ref. Wilson Wx. History)

1967 - Hurricane Beulah moved into South Texas, and torrential rains from the hurricane turned the rich agricultural areas of South Texas into a large lake. Hurricane Beulah also spawned a record 115 tornadoes. (David Ludlum)

1969: On this date through the 23rd, heavy rain over several days brought extensive flooding to the Apalachicola River at Quincy, Havana, and Blountstown; and much of Franklin, Gadsden, Leon, Calhoun and Quincy Counties in the Florida panhandle. Havana 23.42", Quincy reported 18.41" of rain and Blountstown 10.41". Several funnel clouds and waterspouts were reported from northwest Florida to the Keys on the 22nd and 23rd. (Ref. Wilson Wx.

1980: Much of northwest Iowa received violent severe weather. In O'Brien, Clay, Monona, Crawford and Buena Vista counties, high winds and hail pounded crops and buildings. Winds of 70 to 75 mph blew trees down on power lines, houses and cars. Hail up to the size of baseballs severely damaged crops with over $10 million dollars in losses. In Ricketts, every north and west window was broken from the hail. The strong winds destroyed many farm structures in these counties.

1987 - Afternoon and evening thunderstorms produced severe weather in Oklahoma and west Texas. In Oklahoma, a thunderstorm at Seiling produced three inches of rain in one hour, golf ball size hail, and wind gusts to 60 mph which collapsed a tent at the state fair injuring nine persons. (The National Weather Summary) (Storm Data)

1988 - Showers and thunderstorms produced locally heavy rains in central Wyoming, and snow in some of the higher elevations. Casper WY reported 1.75 inches of rain in 24 hours, and a thunderstorm north of the Wild Horse Reservoir produced 1.90 inches of rain in just forty minutes.

1989 - Hugo jilted Iris. Hurricane Hugo churned toward the South Atlantic Coast, gradually regaining strength along the way. Tropical Storm Iris got too close to Hugo, and began to weaken. A cold front brought strong and gusty winds to the Great Basin and the Southern Plateau Region, with wind gusts to 44 mph reported at Kingman AZ. (The National Weather Summary)

1995
A strong late summer storm brought the season’s first snow to parts of the Rockies. Denver, CO reported 4 to 8 inches of heavy wet snow that damaged millions of trees and downed power lines into Boulder leaving 100,000 people without electricity. It took a week to fully restore power to all areas. Total insured losses in the Denver area was $6.5 million dollars. Record cold followed the storm as the low at Denver dropped to 27° the next morning followed by an afternoon high of 36°. Further north, 2 to 8 inches of snow was reported at Cheyenne, WY. Record cold accompanied the storm. Record lows included: Glasgow, MT: 20°, Great Falls, MT: 24°, Havre, MT: 24°, Grand Island, NE: 32° and Pueblo, CO: 32°. Viroqua, WI set their all-time record low for September with 20°.

1998: Hurricane Georges reached its top strength of 155 mph sustained winds when it was 420 miles east of Guadeloupe early this morning; top winds were 115 miles an hour at landfall on Puerto Rico on the PM of the 21st. 28,005 homes were destroyed but only 12 deaths were reported in Puerto Rico due to preparedness. (Weather Guide Calendar with Phenomenal Weather Events 2007 Accord Publishing, USA) Georges' Track - Weather Underground (Ref. AccWeather Weather History)

2000: An F4 tornado devastated some of the same portions of Xenia, OH that were damaged in the April 3, 1974 twister. No tornado warning was issued when the storm struck, raising the ire of local residents. Record heat prevailed across parts of the southwest courtesy of a large upper level heat ridge. Record highs included: Death Valley, CA: 116°, Palm Springs, CA: 115°, Borrego Springs, CA: 110°, Victorville, CA: 104°, Stockton, CA: 101 °F. (Ref. Wilson Wx. History)

2002: A F2 tornado touched down WNW of Washington, IN. It destroyed/damaged several homes. The tornado lifted/tossed a vehicle 1/8th mile; the conservation officer inside survived. (Ref. Weather Guide Calendar with Phenomenal Weather Events 2011 Accord Pub. 2010, USA)

2005 - Hurricane Rita tracked through the Florida Straits and just south of the Florida Keys. Winds were sustained at tropical storm force at Key West, where peak winds gusted to 76 mph.

Extremely unsettled pattern ahead next week. Very high humidity, low diurnal temperature difference, high dews from all the moisture.

Hoping the cutoff low to the SW can finally end the 13th longest daily streak with under 1.00” here since early May.

wow 1983 truly was a historic summer, I miss that kind of sustained heat.....

 

on the flip side, the cold of 1993-94 got started on this date.

we did flip back to Indian summer in November with our latest 80 on record on the 15th, but it was just a blip in time for the NYC Marathon.  The heat only lasted 2 days.

Temperatures will top out mainly in the lower 70s tomorrow and Monday. It will then turn noticeably warmer on Tuesday before another cool front crosses the region on Wednesday. Highs on Tuesday will likely reach the lower 80s with some middle 80s in the warmer spots. The advancing front could trigger some showers or thundershowers.

Some additional rain is possible Thursday into Saturday as a low moves along the frontal boundary. Ensemble support for a significant rainfall is low.

The ENSO Region 1+2 anomaly was -0.2°C and the Region 3.4 anomaly was -0.5°C for the week centered around September 10. For the past six weeks, the ENSO Region 1+2 anomaly has averaged +0.10°C and the ENSO Region 3.4 anomaly has averaged -0.37°C. La Niña conditions will likely develop during mid- or late-autumn.

The SOI was -2.85 today. 

The preliminary Arctic Oscillation (AO) was -0.403 today. 

Based on sensitivity analysis applied to the latest guidance, there is an implied near 58% probability that New York City will have a cooler than normal September (1991-2020 normal). September will likely finish with a mean temperature near 68.9° (0.3° below normal). 

Supplemental Information: The projected mean would be 0.9° above the 1981-2010 normal monthly value.
