Showers and periods of rain are likely tomorrow into Monday. A general 0.25"-0.50" of rain is likely. It will be unseasonably cool with the high temperature reaching only the upper 50s in much of the New York City area and low 60s in southern New Jersey and Philadelphia. Monday and Tuesday will become noticeably warmer. Overall, the first week of May should wind up warmer than normal.

The ENSO Region 1+2 anomaly was 0.0°C and the Region 3.4 anomaly was +0.8°C for the week centered around April 24. For the past six weeks, the ENSO Region 1+2 anomaly has averaged -0.23°C and the ENSO Region 3.4 anomaly has averaged +0.98°C. The ongoing basinwide El Niño event is fading. Neutral conditions could develop later in the spring.

The SOI was +3.16 today.

The preliminary Arctic Oscillation (AO) was -1.742 today.

I love your enso predictions but can we get a prediction on the AO and NAO,, Don, when do you think it will turn positive?

They both might turn positive for a period later next week, but sustained positive regimes may not occur until later in the month.

Low of 51 now to 58.  0.09 in the bucket.  Temps between 50 - 59 today with clouds and showers light rain 0.15 - 0.40.   Warmer tomorrow on SW flow but still mainly cloudy and more showers. Tue (5/7) - Wed / (5/8) brief warm up, pending on sunshine more upper 70s / low 80s.    Clouds return later this week by Thu/Fri and another cloudy/west weekend for Mothers day.  Trough 5/10 - 5/13.   Warmer by mid month, but sustained ridging unforeseen through the second week of May.

Absolutely horrendous pattern now. 50 and muck. Next weekend looks cool and wet again. It’s ridiculous at this point. 

Yup. First half of this month is going to be cool/wet. Just miserable

But warm and dry during the week. 70s Monday to Wednesday. Weekend around 60 and rain. Probably will be nice again next week.

Ensembles have plenty of rain chances moving forward. I think you will have a day or two sprinkled in of 80’s but the majority will be less than ideal

Records:

Highs:

EWR: 94 (1949)
NYC: 90 (1980)
LGA: 90 (1955)
JFK: 84 (1980)


Lows:

EWR:38 (1966)
NYC: 34 (1891)
LGA: 42 (1978)
JFK: 41 (2002)


Historical:

 

1917 - The same storm which a day earlier produced eight inches of snow in the Texas panhandle, produced a foot of snow at Denver CO, their heaviest snow of record for the month of May. (David Ludlum)
1930 - The temperature at College Park, VA, soared from 43 degrees to 93 degrees to begin an exceptional heat wave. (Sandra and TI Richard Sanders - 1987)
 
1933: An estimated F4 tornado cut a 35-mile path from near Brent into Shelby County, Alabama. The town of Helena, AL was especially hard hit, as 14 people died. The tornado roared through Helena at 2:30 am.
1987 - Unseasonably hot weather prevailed in the western U.S. A dozen cities in California reported record high temperatures for the date. Afternoon highs of 93 degrees at San Francisco, 98 degrees at San Jose, 100 degrees at Sacramento, and 101 degrees at Redding, were the warmest of record for so early in the season. The high of 94 degrees at Medford OR was also the warmest of record for so early in the season. (The National Weather Summary)
1987 - Parts of the western U.S. were in the midst of a blistering May heat wave. The reading of 100 degrees in Downtown Sacramento CA was their earliest of record. Sacramento CA established daily record highs on nine of eleven days between the 4th and the 14th. (The Weather Channel)
1988 - A stubborn low pressure system continued to drench the eastern U.S. with rain. Thunderstorms again produced large hail in North Carolina. (The National Weather Summary)
1989 - Thunderstorms swept across Georgia and the Carolinas during the late afternoon and evening hours spawning seventeen tornadoes. A tornado at Toccoa GA injured 15 persons, and a tornado at Chesnee SC killed two persons and injured 35 others. Five tornadoes in North Carolina accounted for five deaths, 88 injuries, and sixty million dollars damage. Thunderstorms also produced baseball size hail at Lake Murray SC, and wind gusts to 78 mph at Brooklyn MD. (The National Weather Summary) (Storm Data)
1990 - A strong Pacific cold front moving rapidly inland caused weather conditions at the east end of the Strait of Juan de Fuca in Washington State to quickly change from sunny and calm to westerly winds of 60 mph and ten-foot waves. Three recreational fishing boats capsized in heavy seas off Port Angeles resulting in five deaths. In California, temperatures soared above 90 degrees across much of the state. The high of 101 degrees in downtown Los Angeles was eight degrees hotter than their previous record for the date. (The National Weather Summary) (Storm Data)
1995: A supercell thunderstorms brought torrential rains and large hail up to four inches in diameter to Fort Worth, Texas. This storm also struck a local outdoor festival known as the Fort Worth Mayfest. At the time the storm was the costliest hailstorm in the history of the US, causing more than $2 billion in damage.

Does look cloudy 9 - 10 of the next 14 days with rain chances.  We'll see how warm Tue/Wed can get,next warm up after then looks like 5/13-5/15 timeframe.

Ensembles wait until Memorial Day weekend for drier and warmer weather

Really is like clockwork. Last spring was the exact same with the weekend wet patterns.

Brutal weather. This weekend was miserable 

Just horrible. Yesterday the temps fell to the low 50s during the late afternoon with the very light rain, and today stuck in the low 50s. Probably not even any beneficial rain today either (probably have to wait until thursday). Our area might only get a tenth of an inch today based on the way radar looks right now. Just chilly damp miserable weather. As you pointed out, we likely have to wait a few weeks before we get to consistently warm weather. Typical for our area.

The Euro is going for a close in tropical tracks rather than recurves with plenty of high pressure over the Northeast.

Looks also like more over the top heat dome in Canada. That big high up there last summer dried it up and allowed the huge fire season that brought the smoke down here on the N flow. Maybe it’ll help keep the hurricanes away if the flow is more east to west vs N up the coast. But that puts FL and the Gulf Coast in trouble. As we know SE FL is way overdue and would make the FL insurance industry go belly up if we have a Cat 4 or 5 into anywhere from PBI to Miami.

The temperature forecast varies a bit from past El Niño to La Niña transitions. Typically the strongest warmth is centered from the Great Lakes into the East. This time the Rockies has the warmest summer departures relative to the means. It looks like we get more onshore flow like recent summers with high dew points rather than dry westerly flow which was typical during past El Niño to La Nina transition summers. Plus tropical systems getting steered into the Southeast and Gulf. So there would be numerous opportunities for the tropical moisture to funnel north.

 After a significantly warmer ENSO run in April, this new Euro run also cooled ENSO back down considerably in addition to significantly warming the MDR (new run on left)(all fwiw of course):
