Radar is just filling in with more and more oranges and reds as it slowly creeps towards se bergen county.  Not going to be a fun drive home.

The lightning here is off the charts. The most lightning I've seen and the closest strikes in years. Incredible storm. Can't believe I still have power.

My road is flooded already. That hasn't happened in a long time. 2.30" of rain in a very short period of time. It's tapering off here now but as you said, the backbuilding is concerning. Hopefully we won't end up getting 4 to 5 inches of rain.

I think parts of Union must have that already

You can see the line starting to wane as it slowly pushes east. Not expecting much here. 

[steve392]

Route 208 in Franklin Lakes,NJ is flooded out.  Glad we are in the southern comm center and hopefully will avoid all the flooding getting home.  Still light rain falling in Paramus.

And with the backbuilding it's pouring here again. Unfortunately this is looking like it's gonna be an epic flooding event. That HRRR run from earlier in the afternoon that I pointed out (5 inches of rain for our area) is going to end up being right. 

[hooralph]

Are the storms moving on the line from Elizabeth/Staten Island towards the city drying up or just moving really really slowly?

[donsutherland1]

Newark has now gone over 1" of rain for the day. The daily mark is 1.90" from 1920. On that day, Central Park picked up just 0.15" of rain. I expect more rain there this time around. Scranton and Harrisburg have now set daily records for July 14. 

[wdrag]

Looks quite threatening from near White Plains into ne NJ. 

Here's a 5" report embedded within 4" near White Plains. I know NWS doesn't use these amounts but if you check the RadarScope STP...its AT LEAST 5" in that area near White Plains.  Just an example.

I'm probably off line til 830P.

You may get 4 to 5
