Yep it was in my western sky. It was definitely bright for a split second.

I saw another tonight - north northeast of me 9:30 ish.I wasn’t really watching the sky this time but happened to catch it.  It probably is a busy sky this week if you can patiently watch.  There is a lot of light pollution up here still (Mohonk area) so star gazing is kinda disappointing generally.

54 here currently; could have a shot at the upper 40s. Windows are wide open!

White Plains has fallen into the 50s for the 10th time this month. The last time that happened in August was 2013. White Plains is on course for 14 such days this month. That would be the most such days since 1987 when there were also 14 days.

[bluewave]

First time with no 90° days at the warm spots from 8-18 through 8-31 since 2011. That year it took Irene merging with the trough and plenty of rain. This time the recurving hurricane and trough over Eastern Canada were enough.

Amazing what low dewpoints can do when given the opportunity. 

The soupy air is one of the reasons why even rural areas can't cool down properly at night anymore.

63 / 51 the nice stretch marches on.  Upper 70s / low 80s the rule the next 3 - 5 days and dry and partly - sunny conditions.  Next shot t rain is Tue-Wed as trough cuts off under the ridge and a steady stream os SE flow into the region, we'll see what it can deliver.   Overall warmer beyond there - next shot at heat into the 4 - 11 period , nothing major or extreme just warmer than normal and ridge building in.

The 95 last year was the one day at 90 plus in the period as was the 91 in 2023, same in 2019,  19th at EWR.  There have been a few with no or one/two days of 90s of late in the period.   We'll see if we can nudge 1 - 3 more in Sep.Oct.

I saw Somerville was 49 this morning, their first 40s I believe.  I made it to 52.  Should be great weather later for the System of a Down concert.  

[wdrag]

If all goes well I'll get Sept thread started by 8PM. 

 

fwiw...5H pattern is looking interesting for me here,  west of I95 where it's been pretty darn dry since the 22nd.  Am I seeing opportunity for for 1/2-2" of rain in nw NJ next week beginning periodically Monday night?  

[MANDA]

Picked up .20" rainfall last night about 9:00 in a quick moving but heavy shower.  Very localized and went right overhead.  Little or nothing within 1/2 mile of here.  Loving the cool weather.  Windows open and a/c off.  JCP&L is sad.

The lowest August average minimum dewpoint since 2014 allowed the minimums to drive the cooler departures at spots like HPN which have been average for high temperatures.

There were 5000 high posts mixed in with people crying that NYC only got to 99

[Brian5671]

and the usual nonsense of posting day 7-10 maps showing 100 degree heat for mid August....
