The temperature rose into the lower and middle 60s this afternoon making for a great start to the New York Botanical Garden's "Van  Gogh's Flowers" show.

I don't know.  It seems the winds have been more prevalent the last 10 years ago, or so.  I think someone on this site has posted some data, suggesting that this is true...

I’m guessing my sarcasm was too thick or not thick enough. The winds have been stupid for months and months. A high of 62 degrees here, 57/49 right now and still on the windy side even though it’s been a couple hours since the last shower came through.

Salvaged the day in Chester but dealt with numerous showers that rotated thru. Nothing a good backyard fire couldn’t fix. 

Down to 48.

and none of those summers were hot either

If you go back to 1990 you can see there's even more of these.... 19! You missed the third place finish in 2017.

Yeah, the usual warm spots could avoid a big year like 2022 and 2010 for 90° days since we haven’t had any 90° days yet.

Gorgeous 52 degree's out, clear blue skies and surprisingly no wind.  Not even a slight breeze.  

[gravitylover]

That bit of sun with now wind was nice this morning. Too bad it couldn't last...

[SACRUS]

 

59 / 45 off a low of 48.  The mainly cloudy from Tuesday PM - Sat PM has ended at around 96 hours - good riddance. "stormy, bring back that sunny day" -   Sunny today near 70 / mid 70s for Mon / Memorial Day.  Clouds return at some point Tuesday and pending on that could see some warmer places approaching 80.   Some rain overnight Tue into Wed Night  0.20 - 0.50.   Clears out later in the day Thu, could be some lingering showers in the morning.  A brief warmup on Friday upper 70s / low 80s before trough comes down next weekend but it looks mainly dry.  

 

Beyond there once to the 5th much warmer (although the GFS would have round 4 or is it five of cut off)  with the western heat coming north and east and height rising first chance at the 90 degree mark in the second week of next month.

Historical:

 

1896: An estimated F5 tornado hit Oakwood, Ortonville, and Thomas, Michigan. Forty-seven people were killed, and 100 were injured. Trees were debarked "even to the twigs, as though done by the careful hand of an experienced artisan." Parts of houses were found up to 12 miles away.

1917 - A tornado ripped through southeast Kansas, traveling 65 mph. The average speed was a record for any tornado. (The Weather Channel)

 

1920: Fussen, Bavaria Germany recorded 4.96 inches of rain in just 8 minutes to set the world’s rainfall record for that length of time.
(Ref. Wilson Wx. History)

1955 - Two tornadoes struck the town of Blackwell, OK, within a few minutes time during the late evening. The tornadoes killed 18 persons and injured more than 500 others. Early the next morning a tornado virtually obliterated the small community of Udall KS killing 80 persons and injuring 270 persons. More than half the persons in the community were killed or injured by the tornado. (David Ludlum) (The Weather Channel)

 

1967: Boston, Massachusetts recorded destructive winds with a peak gust of 70 mph.

1975: On Raccoon Lake, Indiana, lightning struck the motor of a speedboat and traveled up the control wires, killing the driver. The 38-year-old man was knocked into the water by the bolt. His wife and two children, also in the boat, were not injured.

1987 - Thunderstorms spawned fifteen tornadoes in West Texas. One thunderstorm spawned a powerful tornado near Gruver, TX, along with golf ball size hail and 75 mph winds. A man on a boat on Lake Bistineau in northwest Louisiana was struck and killed by lightning, while the other three persons in the boat were unharmed. The man reportedly stood up in the boat and asked to be struck by lightning. (The National Weather Summary) (Storm Data)

1988 - Unseasonably cool weather prevailed in the Upper Midwest. Marquette, MI, reported a record low of 26 degrees. Thunderstorms in the north central U.S. produced wind gusts to 62 mph at Idaho Falls, ID, and produced 4 inches of rain in less than four hours in northern Buffalo County. (The National Weather Summary) (Storm Data)

1989 - Thunderstorms developing ahead of a strong cold front produced severe weather from Oklahoma to Ohio through the day and night. Thunderstorms spawned nine tornadoes, and there were 155 reports of large hail and damaging winds. Hail three and a half inches in diameter was reported at Dittmer, MO, and thunderstorm winds gusting to 90 MPH caused twenty million dollars damage at Rockville IN. (The National Weather Summary) (Storm Data)

1990 - Evening thunderstorms spawned four tornadoes in Kansas and Missouri, and there were three dozen reports of large hail or damaging winds. Thunderstorms produced hail two inches in diameter at Cole Camp, and wind gusts to 72 mph at Rosebud. Heavy thunderstorm rains produced flash flooding in central Missouri. Flood waters swept through Washington State Park southwest of Saint Louis, and nearly one hundred persons had to be rescued from water as much as twenty feet deep. The flood waters swept away a number of vehicles, some were carried as much as four miles away. (The National Weather Summary) (Storm Data)

 

2008: A rare, large and destructive EF5 tornado created a 43-mile long path across Butler and Black Hawk counties in Iowa. This tornado killed eight people, injured dozens and caused several millions of dollars in damage. The tornado was nearly three-quarters of a mile wide as it moved through the southern end of Parkersburg. A third of the town was affected by devastating damage with nearly 200 homes destroyed. This storm produced the first EF5 tornado in Iowa since 6/13/1976 and only the third EF5 tornado to occur in the United States in the past ten years.

Our baselines are high. 

I worry what will happen when we get a real hot pattern set up. We have seen records shattered by huge margins worldwide when a hot pattern sets up over them. Our region hasn't really had that happen in several years. 

I can see the Fpizz to Newark corridor getting to 110F with the right pattern.

Yes-- and number1 and number 2 on that average high temperature list had VERY hot summers.

 

From that chart it can be seen that this spring is very similar to last year's

On the top chart, it's amazing that 1983 had the lowest high since it was the hottest summer here until 2010.... 1983 must have had an extremely rainy spring to keep the highest spring temperature down at 75. 1966 was our hottest summer before 1983 with 100+ degree temperatures starting in June and continuing into July so it's amazing to see its highest spring temperature down at 79 too.

All our summer heat over the last decade had come with onshore flow and record high dew points. This is a result of the big ridge setting up east of New England. So the 100° heat has been mostly found over NJ with only occasional instances into Queens. It has also been a pretty rainy summer pattern. 

From 2010 to 2013 the ridge was to our west over the Great Lakes. So we got frequent westerly flow downsloping events. Even though the dry patterns were modest compared to earlier times, we still maxed out at 108°. 

Parts of the Pacific Northwest had highs 6° above the all-time levels back in 2021. The result of the much warmer climate in the 2020s and the historic droughts out West.

So if this area ever saw a 1960s style drought with 2020s temperatures and westerly flow, then the max temperature potential would probably be 112° to 114°. 

The good news is that it’s very difficult to meet these conditions in this new climate. Since it’s uncertain how well our power grid would function with widespread temperatures that high.

isn't CP all time high 106 from the 1930's? 112-114 wow. Has the earth warmed that much ? With the marine influence on the coast I doubt NYC temps could ever reach that high. The hottest day I ever remember was July 15th 1995. 102 with dewpoints near 80 could kill you. And it did for many of the old in Chicago.

in other words our hottest summers will be a thing of the past?

I don't buy this summer climate being hotter for us than what we had in the past....it's definitely not, not even for NJ, especially if you go by peak temperatures.  It's weird to see it hotter in the PNW, with the ocean to their west lol.

I do think these things go in cycles though, so I do think a 1960s type pattern will return at some point. It's all about extremes and that high has to move at some point.
