Same here.  Still hoping I can crack the .25" mark with some additional showers later on associated with the front.

It's been raining good for a while now, up to .37" and steady rain for now, more than I expected up here honestly.

Just some light rain and mist here now.  Did have a period of moderate rain a while ago that got me to .28".    Radar says anything else will come from the front later.  Looks like that will move through rather quickly but additional showers or a period of rain likely.  I reached where I expected to be so anything else is gravy on the biscuit.

[SnoSki14]

Early glance at Memorial day weekend doesn't look great. 

Maybe some subtropical activity?

[gravitylover]

.9 so far with steady moderate+ falling right now. Good soak. Hopefully the front is equally as productive.

Up to .09

Received zip out here in eastern PA.  Looks like the cutoff was about west central NJ.  Some of the Mesos overdid the western extent of the event yesterday for my area before correcting east overnight.

[weathermedic]

1.5 so far at my station

Up to .54, that's a win here, I had heavily bet the under on Uptons rainfall map this morning and crashed and burned. 

[Allsnow]

.71 good drink today. Didn’t think we would get half of that 

[gravitylover]

Done for a bit I guess. 1.1"

[s2sailorlis]

Wifey is happy...  me too.  have had this station for a week and it works great.  $150 well spent.  Fairfield, CT

 

 

[psv88]

Pouring out here in suffolk. Must be more than 2 inches by now. Much needed 

[Intensewind002]

Picked up 0.22” since noon, 1.3” overall for today

[psv88]

Flood advisory up for Nassau/Suffolk

[uofmiami]

Heaviest about over for Nassau/Suffolk border on West by 7pm or so.  So far 2.30” in Syosset. 

[WestBabylonWeather]

As per my ambient station I’m at 2” and I believe it 

[weathermedic]

Frontal rain looks to be breaking up as it heads east

[lee59]

1.91 inches here so far.

[donsutherland1]

Some additional rain and showers are likely overnight before the clouds yield to sunshine and warmer readings tomorrow.

Through 8 pm, rainfall totals included:

Boston: 0.61"
Bridgeport: 2.26" (old record: 1.60", 1973)
Hartford: 1.64" (old record: 1.25", 1969)
Islip: 1.53" (old record: 1.47", 1972)
New Haven: 1.67"
New York City-Central Park: 0.77"
New York City-JFK Airport: 1.65" (old record: 1.46", 1972)
New York City-LaGuardia Airport: 1.26"
Providence: 1.21"
White Plains: 1.48"
Worcester: 1.04" (old record: 1.03", 1892)

Temperatures will likely remain near or somewhat above normal through midweek before cooler air moves in for a time. Some of the guidance suggests that temperatures could return to the 80s to close the month.

Typically, a very warm April is followed by a somewhat cooler than normal May in the Middle Atlantic region.

The ENSO Region 1+2 anomaly was +2.4°C and the Region 3.4 anomaly was +0.5°C for the week centered around May 10. For the past six weeks, the ENSO Region 1+2 anomaly has averaged +2.57°C and the ENSO Region 3.4 anomaly has averaged +0.28°C. Neutral ENSO conditions will likely prevail through at least mid-spring. El Niño conditions will very likely develop during the summer.

The SOI was -11.32 today.

The preliminary Arctic Oscillation (AO) was +2.689 today.

On May 18 the MJO was in Phase 6 at an amplitude of 2.017 (RMM). The May 17-adjusted amplitude was 1.804 (RMM).

Based on sensitivity analysis applied to the latest guidance, there is an implied 50% probability that New York City will have a warmer than normal May (1991-2020 normal). May will likely finish with a mean temperature near 63.2° (normal).

 

[Dark Star]

Really thought the front might tap into some of the energy from the coastal low, but no dice.  

[Cfa]

2” on the dot. Much needed.

The next 8 days are averaging   64degs.(54/74) or -2.

Month to date is    61.7[-0.1].      Should be 62.4[-0.7] by the 29th.

Reached 65 here yesterday at 11am.

Today:   70-74, wind w. to nw., p. cloudy to p. sunny, 61 tomorrow AM.

56*(78%RH) here at 7am.     59* at 9am.      63* at 11am.     64* at Noon.      70* at 3pm.       71* at 4pm.       Reached 73* at 6pm.      68* at9pm.

Another ugly holiday weekend?

[SACRUS]

0.95 in the bucket.  Clearing out now for a nice day upper 70s.  Overall dry and normal stretch coming up the next 5 days. Highs generally near 70 or low 70s.  Today and Wed (5/24) warmest day of the next five.   

 

Models had been hinting for a while the ridge builds east but cuts of Memorial day weekend.  The last few runs show ULL over the Northeast steering a low through the area Sat (5/27).  We'll see how it evolves - looking like southerly / onshore flow and if the low is steered as the Euro shows could be 24-36 hour ugly Fri-Sat.  

 

Beyond there, ridging pushes through and warmth builds down and into the area.

GFS much less (ugly) but it's Memorial Day and the uglier solution is prone to prevailing. :-) 

We'll see.  Euro had the cut off down in the southeast a few days back but had been persistent there would be something undercutting the ridge.   Looks like trough into the PNW/WC eyond Memorial Day with flatter flow and some ridging pishing east once the cut off / ULL is sorted out.

1860 - A swarm of tornadoes occurred in the Ohio Valley. Tornadoes struck the cities of Louisville, KY, Cincinnati, OH, Chillicothe, OH, and Marietta, OH, causing a million dollars damage. (David Ludlum)
 

1881: Clara Barton and a circle of close friends found the American Red Cross.

1895 - The temperature at Norwalk, OH, dipped to 19 degrees to set a state record for the month of May. (The Weather Channel)

 

1949: A violent tornado crossed the Mississippi River from the St. Louis area into Wood River, then to Roxanna. This tornado damaged or destroyed 300 homes in these two towns, killing five people. Four people died in a destroyed restaurant in Palestine, Illinois; one body was recovered from a tree. A tornado causing estimated F4 damage killed five people and injured 55 in St. Louis and St. Charles counties in Missouri and Madison County in Illinois. This tornado was part of an outbreak that produced four different tornadoes and was responsible for five deaths and 57 injuries.

1896 - The mercury soared to 124 degrees at Salton, CA, to establish a U.S. record for May. (Sandra and TI Richard Sanders - 1987)

1980 - The temperature at Williston ND reached 102 degrees to set a record for May, and the next day the mercury hit 106 degrees. (The Weather Channel)

1987 - Severe thunderstorms, developing along a sharp cold front crossing the central U.S., produced 60 mph winds and golf ball size hail at Sedalia, MO, and drenched Hagerstown, IN, with six inches of rain in one hour. Temperatures soared into the 90s ahead of the cold front. Paducah, KY, hit 94 degrees for the second day in a row. Light snow blanketed Montana, with three inches reported at Butte. (The National Weather Summary) (Storm Data)

1988 - Severe thunderstorms swept across southern Louisiana during the morning hours spawning six tornadoes, and producing wind gusts to 88 mph at Jennings. Thunderstorms also produced five inches of rain in two hours at Lake Charles, causing local flooding. (The National Weather Summary) (Storm Data)

1989 - Thunderstorms moving southeastward across the Central Plains Region into Oklahoma and Arkansas produced severe weather through the day and night. Thunderstorms spawned just four tornadoes, but there were 243 reports of large hail and damaging winds. Baseball size hail was reported at Augusta, KS, and thunderstorm winds gusted to 98 mph at Johnson, KS. (The National Weather Summary) (Storm Data)

1990 - Thunderstorms produced severe weather across the southeastern U.S. for the second day in a row. Severe thunderstorms spawned five tornadoes, including one which injured a person at Richmond KY. There were eighty-seven reports of large hail or damaging winds, with hail three inches in diameter reported at Austin TX. Thunderstorms produced up to five inches of rain in Macon County GA, and heavy rains left nearly eight feet of water over roads near Stepstone KY. (The National Weather Summary) (Storm Data)

 

2001: Golfers participating in a golf tournament at the Majestic Golf Course in Hartland, Michigan received an urgent message on the G.P.S. on their carts. The message, relayed from the clubhouse, was that a tornado was bearing down on the course. Most of the golfers made it to safety in the clubhouse, although some had to take shelter on the course. Only one golfer suffered a minor injury. The F2 tornado damaged 70 cars in the parking lot along with numerous golf carts and a pontoon boat.

[MANDA]

Had .48" rainfall here.  Double what I was expecting.  I'll take it.

Once to the Delaware River amounts dropped off to near nothing.  The wetter models over NJ were very overdone and the drier models were underdone.  Long Island into SNE did the best which is what nearly all the guidance had. 

 

 

 

[Intensewind002]

Finished with about 1.83” of rain here yesterday, about 7 times more than what previously fell this May.

[forkyfork]

we had better get inches of rain from this
