Did well here this am, but nothing since. Think the stuff to the south is sliding too far east to have much of an impact. Unless you’re out east

I agree. I think the worst is mostly over with some drier air beginning to punch east into western NJ . Could see one or two rogue lines of showers/storms if there's any heating between 5-7PM. Other than that, for most of us, it's onto Tuesday. Should be near 90 tomorrow. Tues and Friday the stormy days this week.

southern nj, out over eastern LI and SE New england won today.

East end will be the big winner. The stuff to the south seems like it has eyes on it. Gonna be some big totals out there. Rest of us, things appear to be winding down

I’m 2 miles east of RM Causeway. Might get lucky before it hits the eastern end. Only Mother Nature knows

Is that it for the rain for today?

In Long Beach now, essentially there’s just been just a couple showers here. Maybe something can happen with the rain to the south but we’ll see. 

Same as here. Few showers. Will be watering the garden all week again. 3 miles away it was a monsoon

Crazy. I’m basically due south of you and we did ok. Everything slid SW to NE as it intensified. If you missed it, you were done. 
 

East Hampton is going to put down 12” IMO. Getting absolutely smoked

Complete list of 3" daily rainfalls in July at NYC, and also 3.00" two-day totals. 

(the 3.0" list does not include any slightly lower values that might occur using a day on the other side of a heavy rainfall) Notice that many of the entries are towards the end of July.

Note the 3.0" daily list continues with a few near-3.0" values to balance the entries.

_________________ would rank 6 and 7 if included, and expand total list to 17 entries plus next 3 below for top 20. 

______________ missing out by 0.01" was 22-23 1946 (2.99" from 0.87" + 2.12") and 20-21 1988 (2.99" from 1.28" + 1.71") also 2.91" 3-4 1978 (1.72"+1.19")

________________________________________

* No measurable rainfall on days before and after these entries, meaning they have the same representation in 3.0" list, or no representation if below 3.0" like 29th, 1872;  

** Others have measurable amounts on one or both sides of a heavy amount, only the larger of the two totals is shown for 2d amounts (would have included any nearly equal but there were none). 17th 1877 added only 0.01" so does not make the second list. 

^ Total from 2.27" and 2.06" both daily records. (8-9 July 2021)

You’re only a couple miles east of me and I tripled your total. Crazy summer.

[Rmine1]

From today? I don’t have a gauge, but I’m thinking we were north of 2” in brightwaters. You definitely did better the other day where I got skunked while a storm blew up right over WB

Today was strange. We had rolling thunder for 30 minutes. Then when the rain started no more thunder.

This! Aimed right at the blue dot! Me. Happens more often than not. Not sure why, welcome any explanation

All stations over an inch today except JFK. Record daily rainfall at bdr lga ewr and Islip

Some 7 inch reports just north of Islip

Thx. Hamptons about to be under the gun again 

[weathermedic]

.97 at my station here in Sheepshead Bay

[bkviking]

1.61” for day here in Smithtown, LI on north shore  and it looks by and large over. Just east/southeast of here got the huge totals but still impressive. 

[donsutherland1]

Parts of the region saw excessive rainfall that produced flash flooding. Bay Shore picked up 6.15" of rain. Rainfall amounts through 4 pm included:

Bridgeport: 1.45" (old record: 0.93", 1984)
Hartford: 1.53" (old record: 1.33", 1910)
Islip: 4.63" (old record: 1.22", 1989) ***Hourly rainfall of 3.04" was the 2nd highest on record and a once-in-100-year event***
Manchester: 2.44" (old record: 1.30", 1961)
New York City-La Guardia Airport: 1.38" (old record: 1.19", 1947)
Newark: 1.48" (old record: 1.22", 1933)
Providence: 2.08" (old record: 0.85", 1910)

In the wake of the heavy rainfall, a dry but very warm day lies ahead to start the work week. Readings will approach to top 90° in many locations across the region.

An extreme heat event continues to grip the Southwest. Cities such as Las Vegas, Phoenix, and Tucson could see readings continue to rise toward or above their record daily levels over the next few days.

The ENSO Region 1+2 anomaly was +3.3°C and the Region 3.4 anomaly was +1.0°C for the week centered around July 5. For the past six weeks, the ENSO Region 1+2 anomaly has averaged +2.78°C and the ENSO Region 3.4 anomaly has averaged +0.92°C. El Niño conditions have developed and will likely continue to strengthen through at least the summer. The probability of an East-based El Niño event has increased.

The SOI was -1.97 today.

The preliminary Arctic Oscillation (AO) was +0.035 today.

On July 14 the MJO was in Phase 2 at an amplitude of 0.573 (RMM). The July 13-adjusted amplitude was 0.796 (RMM).

Based on sensitivity analysis applied to the latest guidance, there is an implied 72% probability that New York City will have a warmer than normal July (1991-2020 normal). July will likely finish with a mean temperature near 79.2° (1.7° above normal).

1.5" for the last 2 days, 1" the other night.  2.5" for the week is not bad.  Grass is growing good now.

As always, greatly appreciate your data. I trust your info, but I’m curious about the Bay Shore total of 6.15”. Only because I live in Brightwaters, right next to Bay Shore, and while we had good totals, I don’t think it was that much. How was it reported? Thx in advance 

[Intensewind002]

The event looks largely over but I did pick up another 0.02” giving me a final total of 0.91” for the day

[Picard]

Another shower to throw me over 1.5" for today.  As someone noted earlier - due to the extreme moisture content of the air even the little blips on radar are putting down moderate showers.  Usually the light greens barley reach the ground and only result in a few drops.

[lee59]

.97 of an inch here today, vast majority of it this morning.

[wxallannj]

Only .37"  today in Clifton

[dmillz25]

Finished with 2.17” on the day with 2.47” the last 2 days

[doncat]

Had 1.70" here evenly split last two days.

[SnoSki14]

We're basically near normal for the year and any semblance of drought has been wiped out. 

And with more rains to come we'll probably skew towards AN precip wise. This is a stark contrast to where we were this time last year
