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.

Maybe even a Sandy type track? That pattern looks VERY familiar and the time of the month is right too.

 

That was a once in 700 year track. So most times systems develop to our south exit ENE. If the system is too far OTS, then we won’t even get much moisture. Ideally, you want it far enough west of Bermuda so when it recurves the system in the Great Lakes taps some tropical moisture.

Our main issue since September 2024 has been a lack of tropical moisture. Prior to this we had many tropical systems going into the Gulf or Southeast and weakening they tracked north. This is how we got so many deluges in recent years.

But now we get these weaker Northern Stream disturbances which can’t pick up much moisture. Canada has been in drought also. So this drought which began in September 2024 has continued.

It probably won’t end until someone in the area gets a 10.00” precipitation month followed by numerous above average precipitation months. This is how our past dry patterns have ended

Even last winter we got normal precipitation in December and February with a dry January. So with the exception of last May near MPO, all our months have been either just average or below average precipitation which perpetuated the drought.

We ran out of coffee this morning. Imagine my surprise at 5:30. Talk about spooky season. There will be a Costco run this evening to make sure this never happens again. Then stepping outside to a humid tropical feel was my true wake up this morning!
