How are those models failing? You can't just look at pretty colors on a model and think because it shows a lot of red it means severe weather. The vast majority of the area will see some decently heavy rains.

Because they missed the heavy stuff in central and south jersey while the radar clearly had the focus further south

 

This does not look like reality

No, the line down south is stronger but much thinner. Up here it's a larger area of heavy rain.
