Tomorrow and Thursday will be partly sunny and warmer. Temperatures will likely rise into the lower and middle 70s.

Another system could affect the region Friday into Saturday before a cooler drier air mass arrives. Showers and perhaps some heavy thunderstorms are possible. Following the weekend, it will turn warmer and drier.

The ENSO Region 1+2 anomaly was +0.1°C and the Region 3.4 anomaly was -0.1°C for the week centered around April 30. For the past six weeks, the ENSO Region 1+2 anomaly has averaged +0.68°C and the ENSO Region 3.4 anomaly has averaged -0.05°C. Neutral ENSO conditions will likely continue through at least early summer.

Early indications are that summer 2025 will be warmer than normal in the New York City and Philadelphia areas. The potential exists for a much warmer than normal summer (more than 1° above normal).

The SOI was -1.51 today.

The preliminary Arctic Oscillation (AO) was +1.509 today.

There were three tornado warnings but only one confirmed tornado, that might have been it.

Yep, right near PA/NJ border just east of Allentown.  It was moving north so it could have been the reason for tornado warnings farther north too.

It wasn't much...maybe got us to .75 over the 5 day Euro cut of the  decade

[bluewave]

Warm and wet pattern next few weeks as the cutoff lows undercut the ridge over Southeast Canada.  So an early preview of the Euro summer forecast. Very close to our summers since 2018. Many days in the 60s and 70s with a few low 80s sprinkled in especially the closer you get to Philly and CNJ.

why so many cutoffs Chris?

I miss my hot 90s summers.

Just .06" last 24 hours (8am - 8am) here.  Five day event total = 1.28".  While a far cry from early advertisements of 3-6" it was a slow and beneficial rain event spread over several days.   Some places clearly did better than others but most everyone received .50 - .75".

Beautiful sunny, dry and breezy morning.

Additional rains 1-2" (maybe some locally higher amounts) Thursday night through Friday.

All in all when the recently ended event and the upcoming events over the next 5-10 days get added up the drought conditions should be pretty much erased.

Weekend looks great with seasonal temps. Maybe a bit above by Sunday 

[wdrag]

No thread for 1-3" interior late Thu-early Fri. Antecedent not quite high enough.

Samples attached of actual rainfall via CoCoRaHs and NYS Mesonet. (Fri-Tue). (click for clarity)

Also yesterdays hail reports near our area in green...not necessarily severe hail.

Can't complain about the rain as it was just enough to really wake up my backyards grass.  Everything has shot up over the weekend.  

Enjoying a cool morning outside with bright blue skies.

This morning was kind of surprising. A little damp out still but a nice cool morning with Sun was nice. 

[SACRUS]

 

58 / 49 bright sunshine.  Partly cloudy mid 70s today and most of Thu, but clouds look to return by the later afternoon and evening.  Trough swings south into the northeast and cuts off with rain and cool ENE flow 0.5 - 1.5 inches of rain, more North and west.  Weekend looks to dry out and warm up to or low 80s on Mothers day.  Trough cuts off under the ridge into the south then heads into the area next Tue/Wed with more clouds, showers and rain.  Near normal overall  through mid month, ridging looking to return towards the week of the 20th.

Historical:

 

1840 - A powerful tornado wrecked many boats at the Natchez Landing in Mississippi, then plowed through the city on the bluff. The tornado killed 317 persons, and caused a million dollars damage. The force of the storm caused houses to burst open. The tornado was the most deadly and destructive in early American history. (David Ludlum)

 

1930: Record Maximum temperature for Washington, DC for the date is 95 °F.

1964 - The temperature at White Mountain 2, located in California, dipped to 15 degrees below zero to set a record for May for the continental U.S. (The Weather Channel)

 

1970:  Record Minimum temperature for Washington, DC for the date is 38 °F.

1987 - Thirty-one cities in the western U.S. reported record high temperatures for the date. Highs of 93 degrees at Portland OR and San Jose CA were the warmest of record for so early in the season. The high of 92 degrees at Quillayute WA was a record for the month of May. The temperature at Sacramento CA hit 105 degrees. (The National Weather Summary)

1988 - A powerful storm in the north central U.S. produced up to three feet of snow in the Bighorn Mountains of Wyoming and the mountains of south central Montana. Up to five inches of rain drenched central Montana in less than 24 hours, and flash flooding in Wyoming caused a million dollars damage. (Storm Data) (The National Weather Summary)

1989 - Thirty-two cities in the central and eastern U.S. reported record low temperatures for the date, and 24 hour snowfall totals of 7.2 inches at Buffalo NY and 10.7 inches at Rochester NY were records for the month of May. While northerly winds ushered unseasonably cold air into the eastern U.S., temperatures warmed rapidly in the Great Plains Region, reaching the 90s in Kansas. The temperature at Manhattan KS soared from a low of 30 degrees to a high of 88 degrees. (The National Weather Summary) (Storm Data)

1990 - Gale force winds lashed the northern and central Pacific coast. A wind gust of 52 mph at Eureka CA established a record for the month of May. Strong winds over northeastern Colorado, associated with a fast moving Pacific cold front, gusted to 63 mph at Peetz. Snow developed over the northwest mountains of Wyoming late in the day, and Yellowstone National Park was whitened with 6 to 14 inches. (The National Weather Summary) (Storm Data)

 

1992: A freak snowstorm in the North Carolina Mountains dumped 40 inches at Mt. Pisgah and 18 inches at Mt. Mitchell..
