Why is an onshore flow giving an issue with cloud cover for tomorrow and Saturday even though the ocean temps are much warmer this time of year than in April and May. Thought during the summer months that the onshore flow doesn't have as strong as an influence in terms of cloud cover and cooler temps like it does in April and May when the ocean temps are significantly colder. Just don't get it? I don't mind the cooler air but not with gray skies and no sun at all

New Bnwck: 91
BLM: 91
LGA: 91
TEB: 91
NYC: 90
TTN: 90
PHL: 90

NYC hit 90 a little after 1pm. Soon after, temperatures fell off a cliff.

Several of our stations will finish August near the warmest on record. There were also a number of local stations with a top 5 and 10 warmest summer(JJA). But the high humidity was even more impressive than the temperatures. JFK is at 34 days of a 75 or higher maximum dew point. This is 10 more days than the previous record. It is also a new extreme for 3 consecutive years with so many days. 

through 8/30:

............AUG....JJA

EWR.....#5

LGA......#2......#3

JFK......#5

HPN.....#2......#8

BDR....#2........#3

ISP.....#4........#5

Is this correlated to AGW? Seems extreme.

Impressive to say the least

Back to cannot buy a drop of rain pattern on the island. While we watch central New Jersey get soaked. Patterns have been incredibly consistent. 

Backdoors are usually dry for us with the best moisture convergence to our south.

This is not a backdoor front though. This is a cold front that approached from the west and decided to stall to our south. Just hoping for those breaks of at least seeing some sun both today and tomorrow before the great lovely summer weather makes that comeback on Sunday. I know many people hate the summer heat and humidity but I love it much better thaan the clouds and chill

You can classify it as a backdoor since the high is to our NE with a predominant easterly flow. Typical continental cold fronts have mostly NW to N flow behind them without the present marine layer across the region.

Agree there.   How quick it washes out will determine how much sun vs clouds folks see the next 2 days...here it's actually clearing from the Northeast to southwest....

The clouds from the onshore flow were in a small bank and have already cleared all of SNE and even the far eastern north fork of the island and Connecticut.  The remainder of the area may remain socked in til early afternoon because of the mid and high level decks above it advecting NE in the SW flow at higher levels.  These clouds are mostly associated with blowoff from the showers to the south and may slow down the burnoff of lower clouds.  You can get plenty of low clouds here even in August with onshore flow.  It’s just more common if that flow is SE than NE.  More often ENE or NE flow brings low clouds to New England and decks more in the 2-3K range near NYC if they make it that far southwest.  Time is also a factor.  It often takes 2 days or more of established SE flow to get the low clouds entrenched for long periods.  Those patterns are more common before the typical SW Atlantic summer high develops

The only area I'm concerned about is NYC and the 5 boroughs since that's where I live. Hope the clearing line makes it there today as well and that we continue to have that break in the cloud cover going into tomorrow as well

You bring up how depressed clouds makes you a lot. I'm kind of like you in the spring time because I absolutely hate it, but have you considered Phoenix or San Diego? One area I will try to go more and more to in the spring to get away from the constant gloominess, but right now it does not bother me. It is still nice, dry, and warm outside. New York really isn't known as a 'sunny' city.
