Move to Naples FL-earliest sunset is 5:40pm

Or just be on the western end of a time zone. We're on the wrong side for evening light

Yeah being out in the dakotas just east of the mountain time zone it was still light at like 930 back in mid July. Of course it was also still dark at 6am

The below normal dewpoints and dry conditions this month are helping the daily lows drive the cool departures for a change. Looks like a slightly cooler pattern will continue for the rest of the month. If we don’t see a reversal of this drier pattern, then there could be more 90° heat on tap in September since it would be easy to warm up with such a dry pattern once the ridge returns. 
 

 

90 degree days are just about done for the year (unless we get something like 10/2/2019). For the second straight year, comfortable conditions and a lack of heat will dominate the US Open in Flushing:

Watch the period Sep 4 - 11th  per the european for next shot at 90s outside the hot spots today, there  is also the chance for a wetter / cut off like the gfs / ensembles show to update this map.

Our sunsets in summer are late enough IMO.  It's winter that sucks the life out of you, when you could see darkness approaching at like 3PM

Ten endless battle of locking the clock at ST or DST continues and from the looks of it, we will inevitably remain on the DST Mar - Nov and ST Nov  - Mar change.

would be wild if some states went to permanent DST and others went to permanent ST

Yeah you know the heat will come back. It's too early for it to stay comfortable for the rest of the season. Euro and GFS both show 90 degree weather coming back around the 4th of September. I think we're done with the extreme 95 to 100 degree heat, but we'll see low 90s again. Before then though this is going to be a spectacular stretch of weather for the next 8 or 9 days. 

[winterwx21]

The dewpoint is all the way down to 49 here now, as we begin the long low humidity stretch. 86 degrees.

The main issue is how dry it has been. Newark is currently in the upper 80s on a dry downslope flow behind the cold front. It will get cooler again over the next week. 

Last year Newark only made it to 87° in September. So it hasn’t had two consecutive Septembers not reaching 90° since 2003 and 2004. 

So when the ridge returns in September, it wouldn’t take much for the warm spots like Newark to reach 90°.

83, low dew, wish this was yesterdays weather instead of mostly clouds.

Cooler air will over spread the region tonight. High temperatures will top out mainly in the upper 70s and lows will fall to lower 60s in New York City through at least Friday. Outside the City, lows in the 50s will be widespread. The cool weather will continue during the weekend.

On account of the cool air, August 2025 will be among the five coolest Augusts since 2000. 

There will be higher-than-climatological risk of at least one period in September with highs in the upper 80s or perhaps 90s. Summers similar to the current one have had September highs of 90 or above about 10 percentage points above that for all other years.

The ENSO Region 1+2 anomaly was +-0.1°C and the Region 3.4 anomaly was -0.4°C for the week centered around August 20. For the past six weeks, the ENSO Region 1+2 anomaly has averaged +0.45°C and the ENSO Region 3.4 anomaly has averaged -0.28°C. Neutral ENSO conditions will likely continue into early autumn.

The SOI was +21.06 today. 

The preliminary Arctic Oscillation (AO) was +0.610 today. 

Based on sensitivity analysis applied to the latest guidance, there is an implied 99% probability that New York City will have a cooler than normal August (1991-2020 normal). August will likely finish with a mean temperature near 73.8° (2.3° below normal). 

Supplemental Information: The projected mean would be 1.4° below the 1981-2010 normal monthly value.

That’s like declaring we’re absolutely not done with snow in mid February.

We could get into the 90s in September but each week that passes chances diminsh

Funny - I wonder if I saw the same one.  I am northwest of the city tonight (New Paltz area) and I saw one south and slightly east of me.  Maybe that would have appeared wnw of you.  Rather bright…showed through a thin cloud.  Maybe the same?  I’m glad you mentioned it.
