Saw this from a FB group for nj.  Not sure how accurate it is

This is accurate. for the locations posted---climate sites.  Zooming in gets a few more stations but its only rolling 24 hour rainfall, deepening on the  you select the map.

will post a CoCoRaHs 2 day total at 9A and add some positive comment about the ensembles (global, mesoscale),

I live right near there!

I was right on the edge just NW of the cell's path and still managed almost 3 inches of rain. 

Found a local Wunderground site in Bayside that reported 7.65” in one hour. I am not familiar with this site. But the radar can underestimate the actual rainfall in these extreme events. Home weather stations can struggle to be accurate with so much rain falling in a short time. But it seems like from the flood reports over the hood of the car that it’s plausible 5.00”+fell in around an hour.

Some more fell overnight, total for me was about 1.1”.

Whatever my total was for the area, it was enough to perk up all my flowers and veggies.

Yesterday, Bridgeport recorded 0.20" of rain, while Islip measured 2.93". This marks the lowest rainfall on record at Bridgeport on a day when Islip received 2.50" or more. The previous record was set on August 19, 1990, when Islip recorded 3.83" and Bridgeport received 0.39".

Got about .40 here overnight so something's better than nothing.

[MANDA]

Received .60" here.  Better than nothing and better than excessive totals and flooding.  With the cooler weather the .60" will last a few days and I won't have to water the garden or lawn.  Enough is a good as a feast I guess.

Windows open for the first time in a LONG time.  Love the cooler temps.

CoCoRaHs reports...  you see the 4"s and 5"s  as a sampler.  When you compare the max rainfly axis... I think the EPS had the best idea from the start and all ensembles had the max GENERAL 2-3" rainfall northwest edge of our NYC forum.

HOWEVER:  the value of the MAX potential SPC HREF rainfall posted on p1, was possible in our area. I've not seen max rainfalls but suspect iso 6". 

Therefore the thread had added value using the SPC HREF MAX rainfall...its never perfect but having the max occur in the center of the NYC subforum is no surprise... at least we were bordered N and S edges by the modeling and knowing it's imperfect permits leeway considerations. 

I always keep in mind lack of modeling perfection and leave options open.

Click graphics for clarity.  I chopped off the time covered but trust it's 7/30-31.

Good morning all. 14:51 pm through 01:51 am, Ref NWS, Central Park received .32. The two day total was .60. As always …..

Sad to see so much flood damage in Bayside, Queens.
