About 4 inches here so far but it's starting to lighten up thankfully

Just took a look at the Davis stations in that neck of the woods, you are in the low side of the totals, which is crazy to say.

My parents house in westport has basement flooding. The downtown area along the Saugatuck river got flooding worse than Sandy.

@Brian5671 has been taking it on the chin this summer.  1.20" here, rain just ended

Skies clearing out up to 75 / 70 here

About the exact same here 1.17 glad to have missed the flooding.

[MANDA]

Some breaks in the clouds.  Rain over.  As of 8:00 a.m. had received 1.01".

Looks like maybe .30" in the gauge since then, will measure later.

Glad the heavy totals stayed east.  Doing fine on rain here.  Don't need anything excessive.

Up to 3.74 now. This is a basement filler for eastern Passaic County.

Glad we missed out on those totals around here.  

[TWCCraig]

2.05" and still raining

Another solid event, 19.28" since July 1st

[wxallannj]

We received 4.48"  here in Clifton, highest one day total since we had 8"+ during Hurricane Ida in 2021.

[uofmiami]

Congrats coastal CT!  1.04” in Syosset & only 0.68” in Muttontown.

[SACRUS]

Quite Steamy now 78 / 72

[Rjay]

ISP over 3"

[straphanger]

Ended the event with 1.55" of rain here, nearly 1" of that came between 0600 and 0700.  Welcome rain here after a dry week.

Not looking forward to the muggy weather for the next 18 hours before the cooler, drier air moves in.

Guess it rained a lot!   Lots of flooding in my area.

It was Deadmans Creek that flooded, not the entire Saugatuck. Still the worst flooding I've seen from a rainstorm there ever.

The lows in NYC run cooler than the surrounding urban sites like LGA and EWR. So the tree growth is probably lowering the minimum temperatures also to some extent. In the old days the NYC minimums would average closer to or warmer than those sites before the excessive tree growth.

I would think tree growth would raise minimum temps. I find at my house when the temperature reading is in the open I get good radiational cooling but under tree growth readings are higher.

.70 here

1.7" here.  Looks like a decent week ahead.

[Prue11]

2.44” most of it fell in 3-4 hours mid morning-early afternoon here 

[Intensewind002]

Picked up 1.30" here, much of the heaviest stuff missed

More and more we are seeing these major warm season flash flooding events occur without defined tropical systems. The warmer atmosphere holds more moisture so tropical systems aren’t required. These days all that is required is a weak low or stalled out front.

Northern California has been the place to be so far for cool fall weather.

 

 

Lil preview of december 2026, but the center of heat over the plains instead of the NE.

Those numbers could definitely cause some flash flooding

The problem with trying to predict the winter season is there are a few other things to consider . One being the negative PDO - will it persist into the winter months ??? . Next is the Polar Vortex. - how will that behave ?. Another issue is the lack of melting in the Arctic region and Greenland this summer - 2 important cold air sources. Way too early to make any final winter forecasts.

The lack of melt points to strong PV. So does the QBO. You can't get a worse winter pattern for the northeast in terms of cold. The cold will be bottled up at the arctic like 2019-2020, and the conus will be flooded with pac air.

During the 1970s my worst warm season flooding occurred during Agnes and Belle. The 1980s and 1990s warm season flooding was also mostly tropical storms or hurricanes.

We could probably say the same about the 2000s although some non tropical events began to register. But the 2010s and 2020s are more of a mix between tropical systems and weak lows.

My most extreme rainfall in Long Beach was he weak low in mid-August 2011 that produced 10” during the morning and closed the barrier island to traffic since the areas around the bridges were flooded.
