Henri: Moderate-Major impacts NYC subforum this weekend, possibly into Monday August 21-23, 2021

[NorthShoreWx]

2.21" in north Smithtown.  Much drier than the forecast, but the lawn isn't complaining.  We had frequent wind gusts between 20 and 30 mph for a while this afternoon...kind of like a decent seabreeze on a summer afternoon.

Imagine this was a snowstorm! God we’d be talking about yards in some places!

It's physically impossible to have this kind of moisture in winter here

[sojitodd]

Central Park above 7 inches officially(7.04 inches storm total) as of 8pm. That would be a 24 hour total too since it started at 8 last night.

 

I wonder how that ranks in 24 hour rainfall totals for NYC?

These precipitation extremes were measured at Central Park and go back to 1869. During that time, the heaviest downpour recorded for a single day there was 8.28 inches (210.3 millimetres) on September 23, 1882.

Actually I looked it up and it(greatest 24 hour total-not single calendar day) was 11.17 inches on October 8-9th, 1903. So this is not really close for that at least.

i'm just talking about raw totals. irene maxed out around 8" in nnj but there was a record wet month preceding it

Lee came through before Irene which also led to historic flooding in NEPA.

Not there either . You just have much higher ratios with altitude.

Lee was the worst flooding for NEPA, Central PA and the Southern tier of NY since Agnes in 1972.

Stars are out now! and a really bright planet in the SW must be Jupiter which is the brightest it will be for 13 months!

Then why does their Twitter that I linked above say that Central Park ASOS had 1.94" 10-11 and 1.84" 11-midnight? Are we talking about the same station?

 

"In addition to being the wettest day since 2014... the 1.94" of rain that fell from 10pm to 11pm at Central Park last night was the wettest hour on record for New York City."

 

"The Central Park ASOS broke the daily maximum rainfall record for 8/21 with 4.45 inches of rain! Most of this rain fell over a 2 hour period, with 1.84 inches falling from 11pm to midnight."

 

The generated chart is what is in the database. I am not sure where the differences arise.

Moon and Jupiter look spectacular together, they're also lighting up clouds nearby.

Upton’s Latest QPF map.  I assume they are forecasting this is on top what has already fallen.

 

There will probably be a pause in NYC until Henri starts heading east again.

Im surprised Lee was never retired, if i remember correctly it’s one of the costliest storms not to have that done

[Snowlover11]

thats all she wrote for now, as we await the pivot back east.  not sure how much i’ve gotten thus far probably in the 4-5” range 3.3” today but another station says 5.2”
