Im glad the initial line petered out a bit. Very slow moving. Very ugly if it had more moisture

Almost the last time we had a cold front moves so slow?

That thing covered 100 miles all day long

On and off heavy showers, some lightning. 1/2 inch so far.

Based on radar, LI may be in for some fun @forkyfork

Wantage NJ (this part). Final 2.24". Updating NYC mo total thread shortly as they near 9.5".

[wdrag]

NYC now at 2.02" for the storm as of 510AM.  Much better yield for the city than anticipated, figuring the bigger bands would miss the city.  This has been a productive event.

.9 already this morning in addition to .98 yesterday. Yay...

[hudsonvalley21]

Maybe my Davis is on steroids but 1.88 before midnight and another 0.79 for an event total of 2.67. Interested to see how the totals around stack up. 

[wdrag]

NYC total 2.03 and 9.66 for the month as of 6A. 

[wdrag]

I cannot post 24 hr CoCoRaHs #'s til late today.  Those should be of interest. NYS mesonet added below as of 6A. 

[lee59]

2 inches of rain here and still raining. Feels like fall this morning, rain and in the upper 50s.

[Rtd208]

Picked up 1.22" of rain for the day yesterday.

0.40" of rain so far today.

Storm total 1.62"

That's close to what I got in Cornwall on Hudson.

[wdrag]

Prelim CoCoRaHs climate obs for the past 24 hours ending about 720A.  Will update this eve. Maybe a slight overperformer.  Yersterdays 00z/23 HPC HREF had MAX 4-5" spot amounts but pegged more for the Catskills.  Click map below to see details.

hoping for another .34 next 6 days to get to 10 inches but pattern looks fairly dry

[doncat]

1.40" for event... mtd of 10.22" here on si.  Last three months... July 11.13" , Aug 9.85", Sept 10.22" . An amazingly wet period.

[Cfa]

2.71” here, which is far more than I was anticipating and this is possibly the wettest event this year for me.

6.78” for the month.

Agreed.  Am looking at so called outliers starting to signal a pretty sizable event somewhere Va to Coastal New England. Not accepting any verbatim Op runs. Instead watching ens low pressure trends. My thinking this big ridge over the Great Lakes may flop east into NNE allowing closed low formation e of Cape May.  That would give credence to some of the ops showing big rains near the coasts.  6 days away.   This will be sensitive to Sam upper air interactions, I think.  For now I think dry is too optimistic but I could be wrong.

9.76” as 2.03” fell. It will be tough, but a small handful of ensemble members (around 10%) have enough rain.
