That Montclair total is amazing.  The excessive totals were quite localized but excessive nonetheless.

 

No matter what Fall delivers in terms of cool / cold it is nice to see the first Frost Advisories of the season over the upper         Mid-West.

Daily record rainfall brought flooding to parts of the region, especially Connecticut and New Jersey, earlier today. Drier weather is now taking hold.

The coolest air mass so far this season is poised to move into the region to tomorrow. Highs tomorrow through Wednesday will reach the lower and middle 70s. New York City will see lows in the upper 50s to lower 60s. As a result, Central Park will experience its first reading below 60° this season. the timing matches well with the last two El Niño events: 2015-2016: September 14 and 2023-2024: September 15.

Wednesday through Friday will see temperatures recover mainly to the upper 70s. However, additional cool air will likely arrive some time during the next weekend.
 
The ENSO Region 1+2 anomaly was +4.6°C and the Region 3.4 anomaly was +2.7°C for the week centered around September 2. For the past six weeks, the ENSO Region 1+2 anomaly has averaged +4.12°C and the ENSO Region 3.4 anomaly has averaged +2.57°C. The ongoing strong El Niño, will continue to strengthen through the mid-fall. The Region 1+2 anomaly surpasses the all-time record of +4.5° that was set during the week centered around June 29, 1983. 

The SOI was -25.61 today.

The preliminary Arctic Oscillation (AO) was +1.716 today. 

Based on sensitivity analysis applied to the latest guidance, there is an implied near 50% probability that New York City will have a warmer than normal September (1991-2020 normal). September will likely finish with a mean temperature near 69.2° (near normal). 

Supplemental Information: The projected mean would be 1.2° above the 1981-2010 normal monthly value.
