So far we have .44 inches in NW Suffolk, our first rain from this system. And we just had our highest rate, a little before midnight.

A very light rain has finally started here, our first from this storm system. Still very light and hasn’t even registered on the rain gauge yet.

As our dew point continues to drop, down to 39.6 here in NW Suffolk, we got shut out of the rain today. Wind gust last hour, up to 21.7 from ENE.

I get why the rain shield is not advancing. Our dew point here, which was at 54.5 mid-morning, dropped to 46.9. It fell about 3 degrees from 2 until 3 PM. Winds remain very gusty out of the east, but the highest recorded was only a little over 18 MPH. (update: DP just dropped further to 45.5.)

.56 so far today in NW Suffolk.

Final storm total for last night: .78

Total for the month: 5.99

Meanwhile, News 12 LI is reporting that the NWS is in Mattituck to determine if a tornado caused the damage there last night. A woman had a tree fall onto her house. They have damage pictures on their website.

Rain is starting up again. Already saw 1 severe thunderstorm and a total of .65, so far.

We got .44 in Fort Salonga, in NW Suffolk. Temperature and dew point really started to drop shortly before noon.  Bottomed out around 4 PM, before inching back up. Now 63/59.

.94 for the overnight rains (a rate of 2.78/hour at one point in the 6 AM hour) and, already, 4.75 so far this month. This part of Long Island, at least, has been getting wet.

Total rain from the storms last night and overnight was .81.

Very light, drizzly rain continues on and off. We finally made it to .10, so far.

It's CoCoRaHs observers... I'll update 4 day with what is available at 9A today.  Also will try to find another radar-sensor resource and try to complete the loop at that time. BUT ground truth as yours helps to add perspective that substantial rain (2+) occurred on parts of LI as well. Thank you. 

This Sunday night-Tuesday night looking good for widespread 1/2-4" in our subforum as EC is speeding up. My own confidence on this occurrence is 75-80%.  Only the GEFS is slow.  Think we'll see WPC beefing up in near future D5-7. Looks like spotty excessive (5+) Appalachians to the east coast coming this weekend-early next week

Am still speculating that we're way overdue for a pure tropical event here at the end of the month but can't happen with westerly flow across the country.  

Thank you for the clarification. My neighbor and I both report to Weather Underground, and I also report to the Ambient Weather network. I see the radar totals you posted verified the higher amounts in our section of northwest Suffolk. I use the RadarScope app and noted it there as well.

Attached are 3 day CoCoRaHs totals: we are not done yet across the interior especially tri- state corner. 

The dry slot previously advertised is why outlooks were for 1/2-4". Parts of e LI were under 1/2". Definitely drier near I78 than initially modeled but beneficial nonetheless. 

Next event instead of Sun-Mon will be Mon-Tue as cued by models and a sampler of 48 hour rainfall is attached ending 00z/Wed (Tue evening dinner). The placement will adjust in our subforum. PW will approach 2" across NJ, again.  Speed of front and proximity of sfc low passage will determine max axis...

Our storm total from the last storm was exactly 3 inches. A neighbor had 3.4." That map of storm totals had very incomplete data from Long Island, and seemingly no reports from northwest Suffolk County. On the map that was posted we are just east of Northport, bordering LI Sound. I saw no stations listed there.

2.84 inches, so far today, in Fort Salonga, west of Sunken Meadow, right near LI Sound. Showers now moving SE to NW, as opposed to all the precip south of LI moving W to E.
