The weekend got off to a pleasantly warm start. It will end with a continuation of the recent comfortable readings. High temperatures will be a few degrees cooler than they were today.

Generally near normal to somewhat above normal temperatures will likely persist through the third week of September, if not longer. Excessive heat is unlikely.

Dry conditions will likely persist into at least the middle of next week. Afterward, some moisture from the southeast could try to move into the area, but its progress northward remains somewhat uncertain given an expected strong ridge to the North. Nevertheless, some showers and perhaps periods of rain are possible, especially from New York City southward. Should the ridging wind up weaker than currently modeled, a more significant rainfall would be possible.

In terms of dry weather regionally, today is on track to become Boston's 25th consecutive day without measurable precipitation. That would be tied for the 7th longest dry stretch on record. Records go back to 1872.

The ENSO Region 1+2 anomaly was -0.4°C and the Region 3.4 anomaly was -0.1°C for the week centered around September 4. For the past six weeks, the ENSO Region 1+2 anomaly has averaged -0.30°C and the ENSO Region 3.4 anomaly has averaged -0.10°C. Neutral ENSO conditions will likely evolve into a La Niña event during the fall.

The SOI was -2.91 today.

The preliminary Arctic Oscillation (AO) was -1.212 today.

Based on sensitivity analysis applied to the latest guidance, there is an implied 51% probability that New York City will have a warmer than normal September (1991-2020 normal). September will likely finish with a mean temperature near 69.3° (0.1° above normal).

This could be the first time in the 2020s that the highest September temperature at Newark comes after September 15th. The high for the month so far at Newark was 86° on September 1st. Newark hasn’t had a September high this low since 2009. The cooler pattern is forecast to continue another week or so  before we warm up later in the month. That’s when Newark has a chance to surpass the 86° high on the 1st.

The cool pattern during the last week of May that I pointed signaled Newark not getting to 40 days reaching 90° this year. Most of the past Nino to Nina transitions like 2016 and 2010 made it to 40 days and were much warmer the last week of May. This is a result of the much stronger sea breezes than usual this summer. Notice how Harrison just inland from Newark further from the bay made to 41 days. It was also much warmer the last week of May than the airport. This is a rare event for Harrison going over 40 and Newark staying under.

Yep has been a very boring month.  Autumn is usually is boring . Fast forward to December. 

My early guess is winter will be disappointing. Hopefully, we get 2-3 weeks of legit winter like conditions

8 days at 89 degrees sealed the deal.

70 / 63 some clouds  E - W moving through.   Partly cloudy in the step down .  Low / mid 80s and dry.  One more dry/warm day on Monday sunny and highs near 80 / low 80s.  Tue - Fri  clouds and showers and watch where the steady rain setups.   Ridging over the top sends high pressure down later Friday and the upcoming weeked with NE flow (cooler) but drier again into early the week of 9/23.  Ridge into the east and perhaps a warmer more W flow (SW/NW) to clsoe the month. Overall warmer.

Seems that way..Glad I'm in Central PA now. where climo. gives us more snow threats than the coast(South shore of Long Island formally)..But even here it's been way below normal the last 3 or 4 years. I guess these days it's hope for the best ,and see what you can get

Last winter was mild and ugly but somehow I got over 20 inches for the season. We got lucky with 12 inches of fluff on 2/17
