future cast does not look as impressive for the city as it did at 6:00 pm it should have been pouring in the city by midnight is it will not be maybe 2 to 3 hours later so right away you take a inch of  rain off the table..

I haven't really been tracking this event so forgive me if someone has said/asked this already, but is this going to be similar to a closer to the coast version of the 1991 Perfect Storm? The retrograde and the fact that it may transition to a subtropical or tropical system makes me think maybe.

Maybe we should change thread heading to include the system name Invest 94L.

Tropical Weather Outlook
NWS National Hurricane Center Miami FL
800 PM EDT Mon Oct 25 2021

For the North Atlantic...Caribbean Sea and the Gulf of Mexico:

1. A deepening, non-tropical low pressure system with gale-force winds 
is located a little more than 100 miles southeast of Cape Hatteras, 
North Carolina.  This gale area is forecast to move 
north-northeastward for the next day or so, and could acquire some 
subtropical characteristics before it merges with a frontal system 
by late Tuesday. The extratropical low is then expected to meander 
off the mid-Atlantic and northeast U.S. coasts on Wednesday, 
bringing rain and wind impacts to portions of those areas.  By 
midweek the low is expected to move eastward away from the U.S. 
coast, and could again acquire some subtropical characteristics by 
the end of the week while it moves eastward or southeastward over 
the warmer waters of the central Atlantic.  For more information on 
this system, including storm warnings, see products issued by your 
local National Weather Service office and High Seas Forecasts issued 
by the National Weather Service.
* Formation chance through 48 hours...low...20 percent.
* Formation chance through 5 days...medium...50 percent.

For those interested in the potential tropical/subtropical transition of this storm (mainly after it impacts the NE US and moves slowly east across the western Atlantic), worth reading this summary linked below from the NWS about how a hurricane developed in the midst of the large circulation of the Perfect Storm in Oct 1991. 

Difference here is that the tropical cyclone that developed inside the Perfect Storm quickly moved north into Atlantic Canada and was only a TC for a little over a day (after being subtropical for 12 hours).  In our case, the tropical/subtropical system could persist for many days (til at least Nov 4 based on EPS and GEFS, possibly even a few days after that) as it drifts east and remains separated from the westerlies
