for some reason not all of them came as a EAS alert on my phone.  looks like the rain is moving west from nyc now but will head back east overnight. aint that some stuff, you cant make this up!!

also another strange thing Where I am in throggs neck One area looking towards the bridge and queens I noticed it was partly cloudy and for me where I live looking over north west dark clouds and rain I never seen this before esp that last for a long time and still continue to rain not heavy just light .This was one strange storm

I can see what you're talking about on radar. You're right on the edge of the moisture.

Light rain here now but not far to my west we have a massive slug of moisture that is suppose to rotate through starting around midnight and lasting through about 5/6am.

Jesus up 6" more possibly and 8" for other areas as outlined. This is insane

Another flood warning .heavy rain

So I have trying to get this uploaded the below images as a GIF as it shows this point much better, but cant seem to figure it out.  So instead I found a GIF online of two trop cyclones from the pacific to show the point.  Henri and the cutoff ULL danced around one another in a process known as the Fujiwhara effect or binary interaction until they combined to become one entity.  

https://en.wikipedia.org/wiki/Fujiwhara_effect
The Fujiwhara effect, sometimes referred to as the Fujiwara effect, Fujiw(h)ara interaction or binary interaction, is a phenomenon that occurs when two nearby cyclonic vortices move around each other and close the distance between the circulations of their corresponding low-pressure areas. The effect is named after Sakuhei Fujiwhara, the Japanese meteorologist who initially described the effect. Binary interaction of smaller circulations can cause the development of a larger cyclone, or cause two cyclones to merge into one. Extratropical cyclones typically engage in binary interaction when within 2,000 kilometres (1,200 mi) of one another, while tropical cyclones typically interact within 1,400 kilometres (870 mi) of each other.




Look at how the cutoff low captures Henri, they then pivot around one another until they become one entity, remain stationary for a brief time as they remain cutoff from the mean flow, and then eventually the new ULL(combined Henri and the original ULL) get picked up and finally carried away.  Def a crazy set up to say the least.  

Great illustration SROC! Never knew that tjis nor Sandy?? Would classify under this.

River time!!

Anyone have data on reported storm totals for rainfall? The NWS color graphic is impressive, but I'm looking for reports. TIA!

Sandy's capture was vastly different Mugs. It was pulled in by the main trough. The stalling of Henri reminds me a little bit like Hurricane Harvey. If you recall that was the one that moved inland and sat for several days dropping record rains in Houston Texas. That was because it was cutoff from the mean flow and just sat there until a trough finally came in and picked him up and pulled him out. Harvey didnt however react with any other system like Henri did first before cutting off from the mean flow.

Sorry this is old data.  Ill keep searching

No, this is great. This covers Saturday night up to 10pm last night, which captures almost the whole storm, for me at least. Thank you!!!

So do NAM and HRRR get the gold with this one (to the extent any model deserves it)? Yes, they were late to latch on to the more easterly track solution, but they absolutely got it right on the left hook and the NJ rain in a way none of the other models iirc got at all...

rb924119 wrote:I’ll have some closing thoughts coming over the next day or two, but I would just like to say thank you to everybody for a few things:

1. Your kind words and support for all of us involved in the forecasting process. I’ll expand on this later.

2. Everybody who got involved in the discussion, whether providing analysis, posting updates/observations, and or asking questions. The combination of all of those actions really helped to foster a really great discussion and environment so people could debate, learn, and last but certainly not least, get prepared. The number one mission of a meteorologist is to save life and property, and I think that even though nobody got the track completely correct, I think our ideas and level of alert allowed sufficient time and evidence to prepare for at least a close call. Mission accomplished there.

3. For those of you who quietly followed along, or only sporadically posted, thank you for following us through the entire evolution of this storm. As a forecaster, and maybe the only person crazy enough to go out on the limb as far as I was that this storm was on, I have to admit I was very nervous of raising a false alarm. That’s the one thing, again, as a forecaster, I DON’T want to do. And when I made the first mention of this two Tuesdays ago, and then again last Monday, when I had zero support from anything, I can only imagine what you all were thinking of my ideas at those points lol so thank you for giving me and my ideas a chance, and thank you for following and being a part of the entire process. Your trust, your support, and your enthusiasm are things that I don’t take for granted, and I’m sure I can say the same for all of the other forecasters on this forum. And we do our best to give you the best information we can.

You got the big picture very, very right when almost no one else was even talking about it, and you got the specifics pretty right even if it ended up being north and east of where you thought...so thank you, it was a very fun ride.

Official event total (starting Saturday night) from my weather station in Westwood, Bergen County 4.74". Confirmed with my glass rain gauge.
Unbelievable!
