I had 73.55" in 2011...In one 30 day period from approx 8/5- 9/5 , I measured over 25". Don't think I'll ever see so much rain in that period of time again.

That was an amazing period for torrential rainfall in our area. It was the only time that I got to experience 10" of rain in under 12 hrs. Just about everyone in Long beach with a basement had flooding the morning of August 14th. There was a spotter about a mile or two to my east in Lido that recorded the heaviest total in the area.

...NASSAU COUNTY...
   LIDO BEACH           10.20  1230 PM  8/14  SKYWARN SPOTTER         
   MASSAPEQUA PARK       8.17  1230 PM  8/14  SKYWARN SPOTTER         
   BELLMORE              8.04  1200 PM  8/14  SKYWARN SPOTTER  
RECORD EVENT REPORT 
NATIONAL WEATHER SERVICE NEW YORK NY
234 AM EDT MON AUG 15 2011

...ALL TIME RECORD DAILY MAXIMUM RAINFALL SET AT KENNEDY NY...

A NEW ALL TIME DAILY RECORD RAINFALL AMOUNT OF 7.80 INCHES WAS SET 
AT KENNEDY NY YESTERDAY. THIS BREAKS THE OLD RECORD OF 6.27 INCHES 
SET ON JUNE 30 1984. 

THIS ALSO BREAKS THE DAILY RECORD FOR AUGUST 14 OF 0.96 INCHES SET 
IN 2008.

The teleconnections certainly wouldn't favor suppression, I wouldn't be surprised to see models trend north as we get closer. 

It may trend north, I can see it getting far enough to slam DC, but we need the confluence to be timed differently for a significant hit up here. It'll get up to a certain point and just get squashed east by that confluence. Some models have a reinforcing shot of it right as the storm is winding up on the SC coast. We need that upper low over the Maritimes to weaken so the moist flow can make it further north.

Negative. The high pressure to the north is weaker on nam. Confluence could end up being weaker. The high pressure on nam is concentrated around Idaho instead of Iowa on the gfs. Definitely a better look

Ugh. This is pointless to go back and fourth on but theres a 1040mb high in southern Iowa on that map you posted. It just isn't labeled because the Idahoan high is considerably higher. Just look at the isobars.

Yes some of them moved north, but plenty have also stayed to the south. Each storm is different so will keep following this with everyone.

I’m invested until Thursday 12z runs if nothing seems changed by then than I’m going to take a step back and look at it from the sidelines until than I will look at every run there is!

I hate to bicker but you are right. The last storm was a fluke. Not every storm will trend in a way that NYC cashes in. Sometimes you just have to look at the current setup. It doesn't favor a northern track. It could happen. But it's not likely.

Nam looks perfect usually whenever Amarillo Texas gets a really bad snowstorm we get hit too. And there could be some nasty tornadoes in the most eastern Texas and all of Louisiana. Definitely a strong storm this will break records somewhere in the south and if it comes north all bets are off.

Oh look that 1040+ high again. There's no mechanism to bring this up the coast.

Hey what do u guys think of the nam 0z run I know it’s far but cmc first signaled January 23 2016 snowstorm and nam had it on radar since 84hrs ... than cmc brought it back dumb late but the point is Nam’s the furthest north and at 84hrs it looks like the cmc few nights ago when it was at 180 away.

End result of cmc that run looks horrible for us but remember back in 2016 a few days before January 23 blizzard, the cmc also had a perfect positioned low with a great track but mostly rain

Give it a break for now. For your own good. If you're bored and want a best case scenario look up dec 09. That GEM run(last night) has a similar 500 mb evolution. 

This is going to slide south.

Huge inverted trough signal for C/S NJ, RGEM/NAM/GFS all show potential with amounts as high as 6"+. 

That should be interesting to see unfold, Norluns typically end up further north than forecast.

Yeah. Seems like you can't tell where a Norlun will setup until the day of.
