The tropical feed must gett going later?  Radar looks unimpressive right now, but all the models show quite the QPF dump later on.

Water Vapor Loop shows that the moisture feed is coming from the Carribean

Most of the models are keying in on small vort maxes within the flow that should enhance the rainfall.

 

The one thing that worries me is the convective element involved. When that happens someone is going to get dumped on with maybe 4-5" of rain and someone 30 miles away may end up with less than an inch. This has bust written all over it for a lot of people.

NAM has no rain for NYC, LI and most of NJ tomorrow. It ends the rain tonight.

OK.

 

 

Correction. It has the rain completely ending by 2am tonight for NYC, LI and most of NJ.

According to the NAM, it's a 10 hour rain event for the coast and then it's over. The model is completely lost.

Has the heaviest axis of rain in Pennsylvania where 4"-7" falls.

The 00z Euro has rain over a majority of the region from 18z today until 00z Sunday. It's been very consistent for many runs in a row now, I wouldn't put to much weight, if any in the NAM or the GFS at this point.

 

 

Or the new Srefs, which have an almost identical solution to what the NAM just spit out.

Rain ends by 2am for the coast and the event is now for Pennsylvania.

This is according to the NAM/Srefs.

It's certainly something to consider, but until the Canadian and Euro show something different, one has to be skeptical especially with the NAM having a different solution each run

Yeah its just a mess because one or more models is going to bust big time within 12 hours of an event. Going to be a 'fun' winter for sure
