Huge fail HRRR 

Yes indeed.  I have over a half inch and was progged not to get much of anything.  It was supposed to stay to my north.

Shelf cloud coming in now.

Tonight’s activity coming in.  Minimal lightning associated with it.

The one near Stony Brook looks like a hailer on radar.

This one near Stony Brook still looks nasty.

Can hear the thunder from the storms to my east. Looks like I’ll get hit as the line expands west, but nothing too bad

Hailers as shown on radar near Riverhead and now just north of Bridgeport again.

Looks like volcanic eruption over the sound.

Radar is insane.  Big hailer south of Bridgeport.

The storms over CT and the Sound are pushing an outflow boundary back to the SW.  This is igniting new storms over SW CT.  Something to watch.

I think the Blydenburgh dam failure also happened in late February 1979 during the epic meltout and rains after the early February snowfalls culminating in PD1.  I'll see if I can verify that memory.  Pretty sure there was a working stream gage on the Nissequogue at that time.

Does anyone know if the state / county were monitoring the structural integrity of these structures?

I see convection bubbling towards the north shore.

Sea breeze front is already helping to pop some showers on island.

6.15” storm total here. Wild night. 
 

Sad to see the damage in the stonybrook/Port Jeff area. Per news12 a house collapsed and has been condemned. 

Many pictures out on social media of the tremendous damage that occurred there.  Apparently a levee failed in Stony Brook that contained a pond resulting in the entire contents being washed out to LI Sound.

The event total at my station at Cherry Grove is 0.66” since yesterday morning.  Very minor as compared to the epic totals on the north shore.

My total from yesterday was 3.04” with a two day event total of 3.24”

The line in E. PA has some pretty heavy rain with it. FFWarning for Bethlehem PA area

We are getting a good downpour with this line.  We have received 0.65” in the past half hour.  Rate is currently about 1” hour.

Not detecting any lightning here with the approach of the squall line.

These cells in NJ ahead of the main batch in PA are tiny. Had a 1 minute moderate shower here.

Latest HRRR says our area could get a good storm around 5pm. Later today and tonight doesn't look like a big widespread event, but there will be some spots that get hit hard. 

Those cells are moving at a forward speed of 50-60 mph by my estimate.  The rain won’t last too long in any one area.
