Surprised to see a flood watch for the island. There are some discrete cells off the jersey shore, that could consolidate as they head north. 

[Sundog]

That's an impressive precip shield to our NW.

Not seeing it. The steady heavy rain is well NW and maybe the stuff developing over coastal NJ clips eastern LI. Many of us on LI probably get the shaft zone in between.

58 / 56 light rain here / heaviest N+W. Still think we're good for 0.50 - 1.00 with areas N/W doubling or more than tripling thise amounts.  Clear out Sat and make way for a nice weekend with Mothers Day and Mon the 12th approaching or into the low 80s.  Next system cuts off into the south and slowly comes northeast between Tue - Thu with next round of rains.  Beyond there the recent timing has been kind to weekend weather with perhaps another nice weekend 17-18.   Ridging and more warmth , perhaps heat to close the last 1/3 of the month (in that period, not the whole 10 days).

Yeah I could see the east end getting crushed again while further west gets slotted. We had that super persistent area of convection off the Jersey Shore with the last event too. Must be some sort of feedback with a Gulf Stream eddy.

1894:  Portland, OR had its latest freeze when the temperature fell to 32°. This is the only May freeze in Portland's history.

1966 - Record snows fell in the northeastern Ohio and western Pennsylvania, including 3.1 inches at Pittsburgh PA and 5.4 inches at Youngstown OH. Snow also extended across parts of New York State, with eight inches reported in the southern Adirondacks. (The Weather Channel)

1977 - A late season snowstorm hit parts of Pennsylvania, New York State, and southern and central New England. Heavier snowfall totals included 27 inches at Slide Mountain NY and 20 inches at Norwalk CT. At Boston it was the first May snow in 107 years of records. The heavy wet snow caused extensive damage to trees and power lines. The homes of half a million persons were without power following the storm. (9th-10th) (David Ludlum) (The Weather Channel)

1985 - Lightning struck some trees about 150 yards away from a home in Alabama, and followed the driveway to the home. The charge went through the house and burned all the electrical outlets, ruined appliances, and blasted a hole in the concrete floor of the basement. (The Weather Channel)

1987 - Unseasonably warm weather spread from the Pacific Northwest to the Upper Mississippi Valley. Fifteen cities reported record high temperatures for the date. It was the fourth day of record warmth for Eugene OR and Salem OR. (The National Weather Summary)

1988 - A massive cyclone in the central U.S. produced severe thunderstorms from eastern Texas to the Upper Ohio Valley. A strong (F-3) tornado ripped through Middleboro KY causing more than 22 million dollars damage. Thunderstorms in east central Texas produced hail three and a half inches in diameter at Groesbeck, and near Fairfield. (The National Weather Summary) (Storm Data)

1989 - Thunderstorms developing ahead of a cold front in the south central U.S. produced golf ball size hail and wind gusts to 62 mph at Mira LA, and during the morning hours drenched Stuttgart AR with five inches of rain. (The National Weather Summary) (Storm Data)

1990 - Thunderstorms produced severe weather in the central U.S. during the evening hours, mainly from southeastern Missouri to southwestern Indiana. Severe thunderstorms spawned four tornadoes, including two strong (F-2) tornadoes in southern Illinois. Strong thunderstorm winds gusted to 85 mph at Orient IL, and to 100 mph at West Salem. Thunderstorms drenched northeastern Illinois with up to 4.50 inches of rain. (The National Weather Summary) (Storm Data)

The extended EPS has this rainy pattern into late May. We may continue the recent years pattern of rain on at least one of the Memorial Day weekend days. As the upper low will still be near the Northeast.

This is also the anniversary of the May 2020 snow.

There was 7" at Providence RI in the May 1977 event and over a foot in the Poconos (13-17 inches.) In the May 2020 event we had 2-4 inches in the Poconos over a two day period with temperatures falling into the upper teens and wind chills near 0.

 

That 20" in Norwalk might be a typo for Norfolk, CT, which is in the Litchfield Hills in CT and the snowiest spot in the state.

whats causing these semipermanent upper lows, it feels like it's the same one hanging around for weeks.

Yeah that’s what I was thinking. Norwalk is low elevation right near the coast. Norfolk the opposite. 

[MorristownWx]

.85 already in the gauge already. Much needed. 

[Euripides]

Oh look, just enough rain to wet the ground again. 

Central and south Jersey going to be rising on drought monitor.

Didn't you used to live in Douglaston? Or am I mixing you up with someone else?

[Picard]

The rain finally developed far enough east to put us under a steady heavier rain for several hours.  We were closing in on an inch before I left and it was still raining pretty good.  It looks like we might dry slot, maybe scattered lighter showers after 10 AM or so.  But I think we've already reached at least the low side of the predictions, and the water for the plants is welcome.

NYC will get clipped by this heavy batch. Not sure how much it will end up totaling, but it's better than nothing.

Yes that was me as we lived right around the block from the Douglaston Manor.

Moved to South Old Bridge back in 2014.

That dry slot has given me .75", tripling what I got for the last storm.  Though now there is a dry slot moving in which is totally fine with me.

The question is do you get any more or is that it?

I hope not, but it looks like some on and off showers will continue at least for the western half of nj thats on the edge of that dry slot.

Yeah I’m in West Hempstead at my gf place and it just got really dark. If we end up with any very heavy rain I’ll have to head home to monitor the basement. We had 7’ of water in it during the heavy rains August 23 when we had 10”. My landlord blamed my veggie garden for the flooding! So I have a channel cut through it now that drains out to the street. I graded the ground perfectly so I’m waiting to see how it handles some really heavy rain.
