I did a double take when I saw the Palm Trees here in Rhode Island. Very close to me, but I think it's the town of Lincoln. It looked so odd!! 

I see restaurants on Long Island with palm trees. I believe they die in the winter unless you bring them inside. People want the Florida look up north during the summer months.

It will be interesting to see if the 73° minimum at Islip holds as it would be a new record high for so late in September.

Same at both my stations as well.  That SE wind off the water gave a nice uniform low temp it seems across the island.

[Rtd208]

Picked up 1.04" of rain so far today.

Yeah but it’s never really going away because this is the new normal. Extended warm wet sectors. Like 55 and humid xmas week…

That is literally the worst weather. Too cold for ac but the heat just makes it swampy inside. Uncomfortable sleeping weather.

It is difficult for a variety of reasons (not to mention a very bad idea). It is very difficult to target just a single type of insect. No matter how we do it, there are often non-target species that die off. In Florida they have released GMO mosquitos that will hopefully reduce the population. But more on the ecology side, we don’t want to make mosquitoes extinct. The larval stage feeds tons of amphibians and fish. They are quite beneficial to aquatic systems. We could work to control the larvae stage through fish, etc and many areas do this. You can stock a small pond with fish that will consume abundant larvae. The adult stage as well fed a variety of organisms. While we hate them, and believe me, I get bit aa ton, they are beneficial. Once disease starts spreading though, you Weill see health departments start spraying. NJ actually has one of the best mosquito programs in the country. 

Female mosquitoes and female horse flies are a real pestilence because of being such blood suckers.  I wish there was a way to alter them genetically to prevent them from being able to do that and then combine that with the breeding population.  The GM program in Florida sounds interesting, I want to see how that works- they're certainly worse down there than pretty much anywhere else in the country.

Ahead of an advancing front, the temperature soared into the lower 80s in much of the region. However, for a record 2nd consecutive day, the temperature at New York City's Central Park failed to reach 80° when all of the following cities reached 80° or above: Bridgeport, Islip, New Haven, New York City-JFK, and New York City-LGA.

Through 8 pm rainfall totals included:

Allentown: 1.76"
Atlantic city: 0.74"
Baltimore: 0.69"
Binghamton: 1.29" (old record: 1.24", 2003)
Harrisburg: 1.33"
Mount Pocono, PA: 2.49"
New York City-NYC: 0.94"
Newark: 0.52"
Philadelphia: 1.45"
Scranton: 1.39"
Washington, DC: 1.30"

Additional rainfall is likely overnight into the first part of tomorrow. Behind the front, the sun will return tomorrow and readings will reach the lower 70s.

The MJO had recently been locked in Phase 3 at a high amplitude, frequently in excess of 1.500. Only 2006 and 2009 saw the MJO in Phase 3 at an amplitude of 1.500 or above for 2 or more days during September 10-20. Both years saw September end with a cold shot that continued into the first days of October. Both days saw Central Park's temperature fall to 49° on September 30. A fairly sharp rebound in temperatures followed. October wound up wetter than normal with 7.07" rainfall in 2006 and 5.58" of rainfall in 2009. Normal rainfall (1991-2020) is 4.38".

Despite the guidance of a few days ago and a likely cold shot to end the month, 2021 is still on course to become the 6th out of the last 7 years during which September has had a mean temperature of 70° or above in New York City. Considering that the close of September is still more than 10 days out, the guidance can still reverse. Prior to 2000, New York City saw such warmth on average once every five years. In short, September has become more an extension of summer than a gateway to autumn in the New York City area.

Fall 2021 will likely be wetter to much wetter than normal in the northern Middle Atlantic region. Since 1869, there have been 9 August cases where New York City picked up 20.00" or more rainfall during the summer. Two thirds of those cases (and 4/5 of those with summer mean temperatures of 73.0° or above) had 17.00" or more fall precipitation in New York City. 2011 is probably the closest match in terms of precipitation and a nearly identical summer mean temperature. Mean fall precipitation for those 9 cases was 14.86". The median was 17.35". The 1991-2020 normal value is 12.27".

The ENSO Region 1+2 anomaly was +0.2°C and the Region 3.4 anomaly was -0.4°C for the week centered around September 15. For the past six weeks, the ENSO Region 1+2 anomaly has averaged +0.03°C and the ENSO Region 3.4 anomaly has averaged -0.45°C. Neutral ENSO conditions will likely prevail through September. Afterward, La Niña conditions could begin to develop.

The SOI was -10.22 today.

The preliminary Arctic Oscillation (AO) figure was +1.040 today.

On September 21 the MJO was in Phase 4 at an amplitude of 1.554 (RMM). The September 20-adjusted amplitude was 1.530 (RMM).

Based on sensitivity analysis applied to the latest guidance, there is an implied 87% probability that New York City will have a warmer than normal September (1991-2020 normal). September will likely finish with a mean temperature near 70.6° (1.4° above normal).

All those stations are east. Hearing reports of sun to the east.

I live along the Hudson in line with CPK and we didnt have a drop of sun all day.

Also never hit 80

I woke up in the middle of the night and it felt like a sauna.....

and this was in the Poconos!  We had severe storms overnight with temps near 70 during the day and those storms at night.  Actually it was still in the upper 60s at night when those storms came through

I lived on Sanibel for 3 years. Worked with boat captains and Meteorologists. Being from NY I was fascinated by the different weather down there. It was made clear to me that Florida had a Subtropical climate from just below the Tampa Bay area . North of there was not due to the  continental influence on the weather. I saw the difference especially in overnight lows . As far as the 70's, I still have the Time Magazine that was devoted to ”The next ice age cometh"?. It was very clear how NOAA and the scientific community we're leaning back then.

Interesting that you think your personal anecdotes can substitute for facts. There exists a ton of information on both subjects if you care to educate yourself. Or alternatively, and more likely, you're a republican. Unfortunate.

Pure tropical climates are those in the Caribbean where temps are stable all year round 80- 90 by day/ 70-80 at night. So basically people here are broad brushing subtropical to the point that you are equating our yearly climate to South Florida which is absurd. You want to say we are experiencing stretches of S FL humidity...Have at it. But they don't get a cold frontal passage from mid June till October. Not 1 cool, dry day the entire Summer

Tropical ≠ Subtropical

A sharp negative tilt trough out of the Great Lakes this Saturday the 24th, may place NYC on the western fringe of what could be a sizable rainfall for eastern LI, especially Montauk???

Thereafter, there are possibilities NYC will be on the northern or northwest fringe of a complex mid Atlantic coast-western Atlantic low pressure system that may yet ingest a bit of SAM RH, or at the least have it's overall Western Atlantic flow altered in such a way that LI-NYC is in the mid level deformation zone yielding qpf here of .05 to .75" next Wednesday-the 29th through Saturday October 2. Timing and northwest extent of the showery rains all uncertain but not a zero chance.  Modeling of this is going may be very sensitive to overall western Atlantic response to SAM.  I just don't know but worthy of monitoring. 

AND, as a final observation of modeling: 00z/24 guidance has virtually all members showing SAM not posing a direct threat to the northeast USA, except for 2 tor 3 members.  Will monitor future modeling trends. 

[wdrag]

Unsure about EWR Sept record.  Not starting SAM related thread, as yet...  wait a couple of days to see if indeed there is a more direct interaction with the mid-Atlantic coast low pressure system. What I see on some 6AM weathercasts are tooo optimistically dry forecasts tomorrow and middle-end of next week for NYC-LI-NJ. 

I hope Bluewave and Don have some stats to share on Sept and will recheck late today. 

[CIK62]

The last 7 days of September are averaging 68degs.(60/77) or +3

Month to date is  72.0[+1.5].      September should end at  71.1[+1.9]

59*(88%RH) here at 6am, cloudy, drizzle.      60* at 7am with clearing skies.        67* at Noon.         71* at 3pm        73* at 4pm.      74* at 4:30pm.

Latest GFS has no more rain this month---previous run had 0.3".

SAM, around Oct. 03, seems most trapped on the GFS, but it still escapes.      The CMC blocks it--- but it goes into the SE US.

Today. 68-73, w. wind., some sun by the PM,

Picked up 1.22" of rain for the day yesterday.
