Bridgeport: 5 days, 1957, 1984 Islip: 6 days, 1987 New York City-Central Park: 10 days, 1925, 1991 New York City-JFK Airport: 5 days, 1962, 1984, 1988, 1991 New York City-LaGuardia Airport: 9 days, 1991 Newark: 13 days, 1991 White Plains: 5 days, 1957, 1984

From earlier this evening. There was a brief period of gusty winds followed by a brief period of moderate rain.

Showers and thundershowers are possible tonight into early tomorrow. A few spots could experience strong to severe thunderstorms, gusty winds, hail, and heavy downpours. Tomorrow will be somewhat cooler with highs reaching the lower and middle 80s across the region. Monday will be the coolest day of next week with highs only reaching the upper 70s to near 80°. Afterward, above normal temperatures will return for the remainder of the week. The temperature could approach or reach 90° to end the week. The ENSO Region 1+2 anomaly was +2.2°C and the Region 3.4 anomaly was +1.0°C for the week centered around May 27. For the past six weeks, the ENSO Region 1+2 anomaly has averaged +1.80°C and the ENSO Region 3.4 anomaly has averaged +0.90°C. The ongoing El Niño will continue to strengthen through the summer. The SOI was -27.42 today. The preliminary Arctic Oscillation (AO) was +1.795 today.

The ongoing and strengthening El Niño is already contributing to record warm ocean temperatures. Global sea surface temperatures are currently well ahead of those during the development of the 2023-24 El Niño.

Tomorrow will be fair and hot with highs in the upper 80s and lower 90s. Should Central Park reach 90°, 2026 would become the first year on record that New York City had a high of 80° or above in March and highs of 90° or above in April, May, and June. Some showers or thundershowers are possible early Sunday. Highs will still reach the lower and middle 80s. Somewhat cooler conditions early next week will give way to a return to above normal temperatures for the remainder of the week. The ENSO Region 1+2 anomaly was +2.2°C and the Region 3.4 anomaly was +1.0°C for the week centered around May 27. For the past six weeks, the ENSO Region 1+2 anomaly has averaged +1.80°C and the ENSO Region 3.4 anomaly has averaged +0.90°C. The ongoing El Niño will continue to strengthen through the summer. The SOI was -29.81 today. The preliminary Arctic Oscillation (AO) was +1.795 today.

It might not be as east-based as either of those two ENSO events, but there's still a lot of time before the anomalies peak. It looks solidly east-based, perhaps evolving into a basinwide event as it weakens.

Yes. It's looking like a monster east-based El Niño event.

Tomorrow and Saturday will be very warm days with highs in the upper 80s and lower 90s. Should Central Park reach 90°, 2026 would become the first year on record that New York City had a high of 80° or above in March and highs of 90° or above in April, May, and June. Saturday will remain warm before somewhat cooler air arrives to conclude the weekend. Some showers or thundershowers are possible early Sunday. Cooler conditions early next week will give way to a return to above normal temperatures for the remainder of the week. The ENSO Region 1+2 anomaly was +2.2°C and the Region 3.4 anomaly was +1.0°C for the week centered around May 27. For the past six weeks, the ENSO Region 1+2 anomaly has averaged +1.80°C and the ENSO Region 3.4 anomaly has averaged +0.90°C. The ongoing El Niño will continue to strengthen through the summer. The SOI was -35.29 today. The preliminary Arctic Oscillation (AO) was +1.920 today.

A warming trend is now underway. Tomorrow should see temperatures top out in lower 80s and perhaps middle 80s. Friday and Saturday will be very warm days with highs in the upper 80s and lower 90s. Should Central Park reach 90°, 2026 would become the first year on record that New York City had a high of 80° or above in March and highs of 90° or above in April, May, and June. Saturday will remain warm before somewhat cooler air arrives to conclude the weekend. The ENSO Region 1+2 anomaly was +2.2°C and the Region 3.4 anomaly was +1.0°C for the week centered around May 27. For the past six weeks, the ENSO Region 1+2 anomaly has averaged +1.80°C and the ENSO Region 3.4 anomaly has averaged +0.90°C. The ongoing El Niño will continue to strengthen through the summer. The SOI was -34.80 today. The preliminary Arctic Oscillation (AO) was +1.384 today.

Yes. Precipitation wasn't the problem. The region was flooded with too much warmth. It will be interesting to see how things unfold with the upcoming super El Niño.

15.28" (8th highest).

New York City finished May with a mean temperature of 63.2°. That is exactly normal.

The day started off with near record low temperatures and even some record lows in parts of the region. Lows included: Allentown: 41° Atlantic City: 43° Bridgeport: 45° Danbury: 37° Islip: 43° New Haven: 43° New York City-Central Park: 50° New York City-JFK Airport: 48° (tied record set in 1966 and tied in 1977 and 2023) New York City-LaGuardia Airport: 54° Newark: 46° Philadelphia: 52° Poughkeepsie: 37° Westhampton: 31° (old record: 34°, 2008) White Plains: 42° Overall, New York City finished May with a monthly mean temperature of 63.2°, which is the normal 1991-2020 value. That was 0.8° warmer than the earlier 1981-2010 baseline. The first week of June will likely see temperatures average somewhat below normal to near normal. However much warmer weather could arrive on Friday and then continue through the first weekend of June. The ENSO Region 1+2 anomaly was +2.1°C and the Region 3.4 anomaly was +1.0°C for the week centered around May 20.
