Haven;t really been following this one. Last I looked it seemed like a very minor event but now seems like advisory level snow is possible for NYC Metro?
We've had fast movers with cold air rushing in perform well before. I agree though this is probably around 5-6 inches most areas but I think some places in the metro might get 6-10.
I don't look at 10:1 maps but even the Kuchera maps are showing significant snow now for NYC and points south of NYC. I think people are underestimating how dynamic this storm could be. If the dynamics target Coastal NJ they get raked. It's about where the dynamics are in my opinion more than what temps are at the start of the storm.
LI is in a good spot. NYC probably in a good spot although concern is if the best dynamics are SE of NYC then NYC would deal with white rain due to UHI.
Truthfully you probably don't want to see mostly snow down to near ACY like the RAP is showing if you want big snows NYC area. This will have a pretty narrow axis of heaviest snow I think.
Looks like a March storm but I guess with marginal surface temps they are maybe expecting it to be more like a March storm where UHI makes a difference.

The storm is happening overnight at this point so a trend that dramatic is unlikely. At most this shifts far enough north to hit both the metro and up to I84.
I know I wasn't referring to you. I meant the 10:1 maps that are showing 12+, the surface will be too warm in the areas with best dynamics. I agree 6-12 is reasonable somewhere within 30 miles either direction of the city.
