Thank you. I will have to check it out once I get back from Maine next week.

Is that Xmacis?

Mostly XMacis.

Philadelphia had a nice snowstorm on December 8, 2013. People were caught by surprise. I was there and snapped this photo of Independence Hall.

Not very warm. Up to 1944, it was the 33rd warmest or 17th coolest summer. Through 2024, it is the 108th warmest or 22nd coolest summer.

Sign of the times in Portland, ME:

I am truly sorry to learn of your father’s passing. He was a very good person who helped make this place special. May he rest in peace and may his memory always brighten the world.

It was July 8, 2024.

If so, the last time Central Park was warmer than Bridgeport, Islip, JFK, LaGuardia, and Newark was May 1.

Thanks Bluewave. I will have to check out Nickerson Beach.

Yes. I tweeted about it. It was also the second this year (March 6: 72-62 was the other).

I just arrived in Newport on the first leg of my vacation. However, 1885-86 had 31.9” of snow. Its biggest snowstorm was 5.3”.

Parts of the region saw the mercury soar into the lower 90s today. LaGuardia Airport (92°) and Newark (94°) both reached 90° or above. A front will cross the region this evening. It could trigger some scattered showers and thundershowers. Behind the front, it will turn cooler and much less humid for tomorrow through the middle of next week. Tomorrow through Wednesday should feature bright sunshine, low humidity, and pleasant temperatures topping out mainly in the lower 80s. Low temperatures on Tuesday and Wednesday morning should be in the lower and middle 60s in New York City. Some outlying areas could see lows fall into the upper 50s, especially on Tuesday morning. A brief surge of heat is likely for Thursday through Saturday. Much of the region will see the temperature top out near or above 90° during these days. Friday will likely be the hottest day with temperatures reaching the middle 90s in New York City and upper 90s to near 100° in the hot spots, including Newark. Afterward, it will turn cooler, but readings will likely remain somewhat above normal. The ENSO Region 1+2 anomaly was +0.4°C and the Region 3.4 anomaly was 0.1°C for the week centered around July 9. For the past six weeks, the ENSO Region 1+2 anomaly has averaged +0.52°C and the ENSO Region 3.4 anomaly has averaged +0.07°C. Neutral ENSO conditions will likely continue through the summer. The SOI was +14.28 today. The preliminary Arctic Oscillation (AO) was -0.456 today. Based on sensitivity analysis applied to the latest guidance, there is an implied 80% probability that New York City will have a warmer than normal July (1991-2020 normal). July will likely finish with a mean temperature near 79.1° (1.6° above normal).

Yesterday was yet another day that saw Central Park record the lowest high temperature among Bridgeport, Islip, JFK Airport, LaGuardia Airport, Newark, and White Plains. It was also the 11th time this summer. That is tied with the record for June 1-July 19 that was set in 2017. The summer record is 17 days during summers 2007 and 2017.

Yes, it’s a fairly new station.

College Park picked up an hourly record 2.71".

A few parts of the region could see a shower or thundershower this evening or overnight. Tomorrow will be steamy with highs in the middle and perhaps upper 80s. A few of the hot spots could reach 90°. Additional showers and thunderstorms are possible tomorrow evening into Monday morning as a cold front moves across the region. Behind the front, it will turn somewhat cooler and much less humid through the middle of next week. Monday through Wednesday should feature bright sunshine, low humidity, and pleasant temperatures mainly in the lower 80s. Low temperatures on Tuesday and Wednesday morning should be in the 60s in New York City. Some outlying areas could see lows fall into the upper 50s on Tuesday morning. No widespread and sustained excessive or record-challenging heat appears likely through the first three weeks of July. However, some of the guidance continues to show a brief surge of high heat late next week. The last three cycles of the ECMWF and EPS are particularly bullish with the potential heat. The ENSO Region 1+2 anomaly was +0.4°C and the Region 3.4 anomaly was 0.1°C for the week centered around July 9. For the past six weeks, the ENSO Region 1+2 anomaly has averaged +0.52°C and the ENSO Region 3.4 anomaly has averaged +0.07°C. Neutral ENSO conditions will likely continue through the summer. The SOI was +14.40 today. The preliminary Arctic Oscillation (AO) was -0.452 today. Based on sensitivity analysis applied to the latest guidance, there is an implied 78% probability that New York City will have a warmer than normal July (1991-2020 normal). July will likely finish with a mean temperature near 79.0° (1.5° above normal).

The snowiest city could be Valdez, AK with average annual snowfall of 325.3" of snow.

Yes. I recall it. I was visiting my sister in Patchogue.

Yes, January 29, 2022 (7.3”) was the last 4” or greater daily snowfall at Central Park.

I agree with you. I saw the time stamp of June 5 on the chart and checked the NYC data since then.

The NYSWRCC chart is not current. New York City (Central Park) had no rain during the weekend of July 5-6. It's longest such streak on record where there was at least a trace of rain on one of the weekend days was 12 consecutive weeks (June 22-23, 1895 through September 7-8, 1895). Each weekend saw at least one day with measurable rainfall.

The timing of the steep drop in the PDO reflects the reality that the hydrothermal vent field in question has virtually no influence on the SSTAs given the vast amount of energy required to heat the volume of water in question.

I agree that 2013-14 is probably at the cold/snowy side of the envelope for what could lie ahead. I hope something close to it plays out rather than something like 2011-12. Like you, I suspect that the PDO- will relax somewhat toward winter, but the redevelopment of a La Niña will likely limit how much it fades. RONI is already in La Niña territory. The cool SSTAs off southern California/Baja California could also impede the subtropical jet leading to a drier winter in the Southwest and reduced opportunity for Miller A storms in the East, if they persist. Miller Bs typically favor New England with a sharp drop in seasonal snowfall somewhere in the Middle Atlantic, greatest risk Baltimore and southward, but sometimes New York and southward. NYC is moving closer to setting a record for its longest drought without a 4" or above daily snowfall. There could still be surprises. Last winter's historic snowstorm that affected Houston to Pensacola (historic New Orleans eastward) was one extreme example.

It’s tough to see the PDO- completely breaking down and switching to a PDO+ for winter. Did he present evidence to support his proposed evolution?
