For the metro corridor this evolved into basically a 6-hour heavy rain event with the really huge totals mostly falling within a 2-3 hour period.

No. Unless you mean someplace else in the state? 

Yeah. I think the Hudson Valley has an outside chance.

Tornado Warning for Manhattan, Bronx and Westchester

 

[doncat]

Approaching 6" here.

[jm1220]

Central Park has to be getting 2-3" next hour at least. Likely to be more flooded subways. 3rd time this insane rain rate has taken place this summer.

13" in like 2.5 hours lol

Lol that 3hr “record” will probably stand forever, but I think the official 24hr record is in jeopardy in this era of mega-rain.

If the Harrison, NJ totals can be verified, then it’s close to exceeding the ISP 1000 year event in 2014.

It looks like that is a WxFlow station thus a haptic rain sensor. Take it with a grain of salt especially with any wind.

It’s a wxflow sensor, can’t be used

Seeing rotation NW Suffolk along the WF, probably needs a SMW over the sound

Pretty wild day for these parts 

[eduggs]

Large areas of Middlesex, Mercer, and Somerset Counties in NJ have probably received historic 2-hr rainfall totals. 25-yr and even 100-yr rainfall intensities happen pretty regularly throughout the state in individual thunderstorms, but it's less common over such a wide area.

Should get to 5” plus here

The only thing I'm upset about is this is happening at night.  It would be much more spectacular looking for funnel clouds at 1 in the afternoon which is what we were doing in November 1989 and again on Labor Day 1998

[lee59]

Temperature has risen a quick 4 degrees here to 72, winds gusting to 28mph

[dWave]

NYC CP as of about 908P  2.13 out so today. Note wind directions below. Unsure if wind eqmt out or a GW? or just a convergent zone.

Now that really reminds me of Nov 1989, the big front door to our high school had swung open and it was so windy you couldn't shut it and the whole school was shaking as if an earthquake was happening.
