Today was about as perfect as it gets 

my allergies calmed down after around 2 PM, maybe the wind died down around then or did the humidity get lower? Or both lol

Under mostly sunny skies, much of the region saw temperatures reach or exceed 70° today. Highs included:

Atlantic City: 70°
Bridgeport: 70°
Islip: 70°
New Haven: 71°
New York City-Central Park: 70°
New York City-JFK Airport: 70°
New York City-LaGuardia Airport: 71°
Newark: 73°
Philadelphia: 72°

A cold front will move across the region tonight into tomorrow morning. Low pressure will likely form along the front and move across the region. Periods of rain and perhaps some thunderstorms are likely into tomorrow. A period of severe weather is possible. A general 0.25"-0.75" rainfall with locally higher amounts appears likely.

Following the frontal and storm passage, temperatures will top out in the lower and middle 60s through midweek. A stronger push of cold air could arrive afterward. Cool temperatures will likely persist through next weekend.

The ENSO Region 1+2 anomaly was -0.1°C and the Region 3.4 anomaly was -0.3°C for the week centered around October 8. For the past six weeks, the ENSO Region 1+2 anomaly has averaged -0.12°C and the ENSO Region 3.4 anomaly has averaged -0.42°C. La Niña conditions will likely continue through mid-winter.

The SOI was +7.60 today. 

The preliminary Arctic Oscillation (AO) was -0.919 today. 

Based on sensitivity analysis applied to the latest guidance, there is an implied 63% probability that New York City will have a warmer than normal October (1991-2020 normal). October will likely finish with a mean temperature near 58.5° (0.6° above normal). 

Supplemental Information: The projected mean would be 1.6° above the 1981-2010 normal monthly value.

 

Last 70 for the season Don?

I think it's always highly suspect to predict the last 70 because it can be 70 in the middle of winter too, I remember we have hit 70 a few times in January including January 2006 here, 11 years to the day that we got the Blizzard of 1996 lol.

Yes 70 areawide including the south shore!

It was sunny pretty much all day right up until sunset here too!

TV Mets messed up the high again and said it was 69 lol

It’s unfortunate that they don’t verify their numbers before going on air. It is not a difficult task.

I don’t know. Probably for at least the next week or longer.
