12Z GFS is a complete miss to the east - very little precip west of Long Island
12Z Icon is an impactful storm for most of the metro - moderate to heavy rain
The reason for the difference is the placement of the HP in Canada - the HP on the Icon stays north of the storm blocking it into the coast - HP on the GFS is northwest of us in south Canada - not blocking the storm movement to the north and preventing it from getting too close to the coast
One constant is the strong winds - wouldn't be surprised if there are high wind warnings issued
