One-3" of rain expected NYC sub forum 1P Wed-1P Thu 12/29/23 and may result in minor small stream flooding Thursday, especially Northern NJ near NYC. Isolated 4" possible.

here in the lehigh Valley- have 2.5 inches in my gauge thus far-- flooding getting bad. ABE will destroy its all time record for total precip for the month of  December tonight. Thats a huge headline. 9 inches is closing in for total rainfall for the month with much more at my house . I am hitting around 11 inches thus far at my house where the fire hose keeps coming at us

ABE has already broken its old monthly record of 7.89” from 1973.

[Tatamy]

Event total up to 2.37”

WU now projects 0.77 ' for their day, with another 0.32 " forecast for tomorrow. Thus far no sign of the 'heavy rain' that was anticipated.

Who cares? 

[RedSky]

3.50" of rain not snow

 

[Pequest]

2.10" still coming down. 

[TriPol]

The northern part of the area is covered in reds and yellows.

I'm sitting at 2.65" with at least two hours of .65"-.80"/hr rates. For the month of December I am at 10.85". I can't take more rain. Are we done for a while? There is no where for water to go.

[Rtd208]

@MaureenPicked up 1.42" of rain for the day. Storm total 1.83"

[wdrag]

NYC CP at least 1.36.  I'm anticipating another 0.2-0.6 for the entire NYC subforum between 7AM today and 7PM Friday. SFC trough west from the ocean low and upper air low pressure to our south are the causative factors.

Plenty of minor stream flooding I95 corridor in NJ and heaviest moderate flooding in eastern PA, especially w of PHL.  

Modeling: EC and CMC seemed best to me when this thread started. GFS woeful... just no clue.  In the shorter range... you can choose.. I think the HRRR/RGEM had best idea of 3" plus numbers (presuming that occurred nw NJ/e PA)... but high res short range location while west of the woeful GFS, varied back and forth from e PA into NJ.  SPC HREF was too far east overall.

This is not done... biggest occurred but aggravating additional amounts will prolong minor flooding episodes in NNJ/se NYS/CT into Friday--no evaporation.

A map of amounts will post around 9A.

Quick snap shot on rainfall amounts... more detail after 9AM.  

 

Max I see in the NYC suboforum is 3.4" Click for clarity,

Thanks Walt, do you have any for just north of Lehighton up by I-80 in that area?

Best rain ended up west of  the short range models 

[hudsonvalley21]

2.10” in the Davis so far for the event.

[MANDA]

Two day rainfall = 2.48".

December = 10.43".

2023 = 63.76"

[bkviking]

2.17” since yesterday in Smithtown, LI. Pretty decent ponding and driving rain up along Vets Highway this morning on way to Ronkonkoma. Total 8.97” so far for month 

[guinness77]

Didn’t see anything about wind in the forecast and we got gusts around 40mph earlier and we’re pushing 30-35 now. Garbage day around here, there’s shit all over my street. I guess NWS doesn’t think 40mph gusts should be noted in the forecast or this was just not expected? Oh yeah, still pissing rain. Lots of big, cold, drops. 

[Cfa]

2.70” and counting, December, which was only slightly ahead of July, is now the wettest month of this year. All rain.

1. December: 10.60”

2. September: 8.40”

3. July: 7.80”

Year: 60.70”

This month is probably the first to breach the 10” mark for my PWS, and this is easily the wettest year on record, very feast or famine though with a few months being bone dry with less than 2”.
