Historical:

 

1794: A frost was reported at Mansfield, MA, repeating a previous occurrence made on May 17th. (Ref. Wilson Wx. History)

1806 - A total eclipse of the sun was viewed from southern California to Massachusetts. (David Ludlum)

1895: Heavy rain fell in portions of central Arkansas, damaging several roads and bridges. At Madding, east of Pine Bluff, 6.12 inches of rain fell in six hours.

 

1906: On this date through the 17th, a tropical storm moved north out of the Caribbean, through the middle Florida Keys and exited into the Atlantic near West Palm Beach, gaining hurricane strength over the Atlantic. (Ref. Wilson Wx. History)

1917 - The temperature soared to 124 degrees at Mecca climaxing the most destructive heat wave of record in California history. (David Ludlum)

 

1921: Yosemite Valley, CA received a trace of snow, their latest on record for this late in the season. (Ref. Wilson Wx. History)

1924: A short, but intense heat wave in Wichita Falls, TX reached its peak on this date. The maximum temperature was 111°. This followed a high of 110° on the previous day, and was followed by 108° the next two days. (Ref. Wilson Wx. History)
 

1944 - A tornado in Sioux City, IA, traveled an odd course. It spun in one place for about twenty minutes, made a U-turn, traveled southeast for about three miles, then traveled south, east, north, and finally east again. (The Weather Channel)

 

1964: A late season snowfall left a trace of snow over all of northern Maine. Guttenberg, IA set a record low for June with 40°. (Ref. Wilson Wx. History)

1965: On the 16th and 17th -Severe floods occurred in Colorado as 12 to 14 inches of rain fell on portions of the east slopes of the Rockies and the plains east of Denver. 14 inches fell in just three hours at Palmer Lake and Larkspur, CO with 12 inches at Castle Rock. A wall of water as high as 20 feet roared down both branches of Plum Creek into the South Platte River near Littleton and through Metro Denver. Flood waters spread to a width of a half mile in Denver. The citizens of Denver received reports of the flooding to the south and had a few hours to initiate evacuation procedures along the South Platte River greatly limiting the loss of life. Around midnight, the torrent crested at 25 feet above normal with the flow exceeding 40 times normal. This is the record flood on the South Platte and many of its tributaries. Many homes and businesses were destroyed. Damage totaled $230 million dollars. 8 people were killed. (Ref. Denver, CO Weather History)

 

1972: Agnes was first named by the National Hurricane Center on June 16, 1972: It would go on to make landfall between Panama City and Apalachicola, Florida, on the afternoon of June 19. Hurricane Agnes would later cause catastrophic flooding in the mid-Atlantic states, especially Pennsylvania. Agnes caused over 100 fatalities.

 

1975: New York City--Two children were killed and seven injured by a single bolt of lightning when they took refuge from rain under a tree in Central Park.

1987 - Temperatures soared above 100 degrees in the Upper Midwest, reaching 104 degrees at Lincoln, NE. Thunderstorms produced wind gusts to 96 mph at Valley City, ND, and baseball size hail near Red Oak, IA. (The National Weather Summary) (Storm Data)

1988 - After a brief respite, hot weather returned to the Northern High Plains Region. Late night thunderstorms in Montana produced wind gusts to 70 mph at Polson and north of Lake Seeley. (The National Weather Summary) (Storm Data)

1989 - Daytime thunderstorms produced severe weather from northern Florida to the Middle Atlantic Coast. The thunderstorms spawned eight tornadoes, and there were 138 reports of large hail and damaging winds. Thunderstorm winds gusting to 87 mph caused twenty million dollars damage at Columbia SC. Strong thunderstorm winds killed one person at McLeansville NC. (Storm Data) (The National Weather Summary)

 

1992: A devastating tornado ravaged portions of southwest Minnesota. Commonly referred to as the Chandler-Lake Wilson tornado, this tornado destroyed more than 75 homes, with another 90 houses, 10 businesses, a church, and a school damaged. In addition, the tornado caused over $50 million in property damage, resulting in more than 40 injuries and one fatality. Based on a detailed damage assessment by the National Weather Service, it is estimated this F5 tornado packed winds over 260 mph as it tore through the residential area of Chandler, Minnesota. This was the only F5 tornado to occur in the United States in 1992.

 

 

2008: Western and central New Yorkers experienced a rare widespread large and damaging hail event. For two hours, cell after cell rolled along a similar path across southern Niagara, southern Orleans, Monroe, Wayne and northern Cayuga counties many of which had hail of up to an inch-an-a-half diameter. Then more thunderstorms that formed later produced hail up to two inches in diameter, a rare event for western New York. One thunderstorm formed over Grand Island intensified as it moved southeast across the densely-populated northern and eastern suburbs of Buffalo. The golf-ball sized hail damaged thousands of automobiles as well as windows, roofs and awnings on homes. At the Amherst Middle School, the hail pierced 1200 to 1500 holes in the skylight roof. While property damage was significant, the damage to area crops was devastating. The hailstones pummeled fruits leaving divots and cracks. Vegetable plants were stripped of their leaves. Apples, peaches and pears that were not stripped from the tress and could have been sold for eating fresh will have to be sold for processing at a substantially lower cost because of being misshapen and bruised. The U.S. Department of Agriculture issued a Disaster Declaration for Erie, Genesee, Monroe, Ontario, Orleans and Wayne counties. (Ref. Wilson Wx. History)

2014: The Pilger tornado was the most intense of the family of tornadoes produced by the supercell. This tornado developed about 6 miles southwest of the town of Pilger and moved northeast, directly striking the city. Initially narrow and relatively weak, the tornado significantly intensified as it neared the Elkhorn River and moved into town. The tornado cut a path through town, destroying numerous homes and businesses. The tornado was responsible for 1 fatality in the town of Pilger and several injuries before moving northeast and weakening. During a weakening period, the tornado again intensified, producing additional violent damage 4 miles northeast of Pilger. Finally, the tornado narrowed, weakened, and turned east, wrapping around the developing Wakefield tornado before dissipating.

62 / 58 day 3 and hour 58 of the latest cloud invasion. 0.89 in the bucket since Friday night.  Cloud lingering much of the next 36-42 hours keeping temps more like April but there is heat (light) at the end of the proverbial dingy grey tunnel we have been in.  Warmer by Wed but front is still pushing the boundary north to trigger storms but we should see some sun and spike temps into the 80s. Chance of storms Wed and Thu evening. 

Thursday, pending on clouds sees >16c 850MB temps and the chance of the next 90s for some and first for many.

In what could be a period of 8 of 10 90 degree days (6/20 - 6/30)  with heat building north and east and a strong ridge pushing heights to >588- 594 DM next week.  Watch for any undercutting the ridge to create any onshore for coastal sections.

 Hot period with an overall higher heights warm-hot but could be featuring storms potential in the beyond.

 

6/16 - 6/18 : Clouds cooler - warmer wed 0.25 - 0.45 inches forecast (scattered)
6/19 - 6/20 :  Warmer - hot in areas (6/19) 
6/20 - 6/30 :  Hotter with strong ridge into the EC  - could remain with storm potentials keeping it
Beyond  : overall wetter and hot

 

 

why will it be wet in the long range Tony? Hot means dry most of the time, any *wet* would be confined to inland areas where scattered tstorms occur but these do not reach the coast most of the time.

Did Agnes make landfall near JFK too?

wow this must have been absolutely amazing, was totality reached in NYC?

It doesn't really factor in when NYC and JFK don't factor in.  The 40s and 50s were quite a bit hotter.  I know you like to use micronets but perhaps if we had micronets in the 90s they would have been even hotter.  Hell, I'm going to start using my car thermometer lol.  Back in 1993 my car thermometer registered a temperature of 106 degrees driving through Queens which was only matched in 2010 and 2011.

 

Why don't we wire in everyone's car thermometers into the micronet that way we can cover the entire region?

There were 100 degree readings in NYC  2021

Once the ridge relaxes around 6/27-28, heights remain elevated but it would turn/hot humid with chances for storms keeping rainfall normal - above.

Yes, and 106 readings I got in my car driving through Queens in 1993, 2010 and 2011.  I agree that there are some parts of the city that are hotter than others, so if we can use some thermometers, we should be able to use them all.

That’s only for places near the immediate South Shore and Eastern Long Island. Most of the area away from the beaches and sea breeze influence have experienced all-time numbers of 90° days this decade especially closer to Central NJ. So the heat is much more widespread than it was back in the 1950s. Nearly every year this decade someone in NJ is getting to 40 days reaching 90°. Those instances were few and far between in the older era.

The models look hot as hell in the long range. 

Hopefully they're all wrong. 

why, this weather really sucks.

fortunately humans can modify their own climate and I have my space heater running at 83 degrees since last night (yes I boosted it a degree because 82 made me feel cold last night.)

The 83 degree setting on my space heater compensates for the lack of sun and also eradicates this excessive moisture at the same time, killing mold.

It feels really nice here with a nice dry 83 degree heat (actually it's 85 since the heater only stops when my room temperature hits 85).

My rule of thumb is I can tolerate temperatures in the 60s when there is no wind and the sun is out.  But if there is no sun and it's windy my heat needs to stay on.  The space heater nicely compensates for the lack of sun and nukes the moisture in the air too. My indoor humidity is only 44% right now.

It need to be below 72 for me to sleep comfortably. Anything above that and I need a fan blowing in my direction. I can sleep just fine with temps as low as 60 indoors, I just use a comforter. Sleeping in the 80s would be impossible.

This is absolutely amazing, I wonder if I can match or exceed my 105.6 reading down here from July 2011. I'll take a picture of my digital thermometer if it happens, just like I did back then.

Interesting in 2024 and 21 the ridge position switched and trended north over time witihin this timeframe, while this time appears to be stable.  We shall see.   That strong storm over the plains ND is pumping the flow SW and building the ridge.

it's different dry vs wet.  I have a really bad mold allergy problem and I sneeze too much to be able to sleep if the air is really moist.

Yes I would like to see a traditional 40s and 50s style heat ridge.  I think climate change is messing with our ridges and making it more wet and less hot here in the summer so maybe we can reverse that now.

I wasn't alive in the 50s when those historic heatwaves occurred in 1953 and 1955 that haven't been matched since, but I was alive in the 1990s especially years like 1991 and 1993 when it was hotter here with less rain and more sunshine.  I feel like our springs have gotten cooler and wetter since then.

Central NJ has always been a heat paradise lol.

Incidentally, the great 1953 heatwave and historic number of 95+ days in 1955 at both NYC and LGA hasn't been matched since either.

I agree that climate change is changing our climate, but I don't think it's making our extremely hot days any hotter, it's increasing the mins and making it wetter.  Otherwise why is the 95+ record at both LGA and NYC still from 1955?

Specifically 1953 and 1955. I added more to the post Tony.

Although we can also add in 1948 and 1949 which were exceptionally hot too.

1949 8 100+ days at Newark only exceeded in 1993 with 9.

NYC 5 days of 99+ at NYC never matched or exceeded (and 4 days of 100+ in 1953).

Incidentally, the great 1953 heatwave and historic number of 95+ days in 1955 at both NYC and LGA hasn't been matched since either.

Maybe there was some cyclical factor that made the period from 1944-1955 exceptionally hot? And maybe that cyclical factor repeated itself between 1991 and 2002?

Note that both periods were 12 years in length......

I don't know about the other summers but I can list the exceptionally hot ones from both 12 year periods:

1944

1948

1949

1953

1955

 

and

1991

1993

1995

1999

2002

hmmm both 12 year periods had 5 extremely hot summers.....

While those 1950s heatwaves were intense while they were occurring, they didn’t t have the lasting power of extended stretches of 95°+ heat that has become common during the 2010s and 2020s. This is the top 11 for 95° days at Newark. 1955 only had 17 days reaching 95° in 1955. Newark has exceed that number twice since 2021. Last summer Central NJ had 21 days which surpassed 2002 and 1955.

While those 1950s heatwaves were intense while they were occurring, they didn’t t have the lasting power of extended stretches of 95°+ heat that has become common during the 2010s and 2020s. This is the top 11 for 95° days at Newark. 1955 only had 17 days reaching 95° in 1955. Newark has exceed that number twice since 2021. Last summer Central NJ had 21 days which surpassed 2002 and 1955 there.

Chris, isn't the consecutive 95+ streak at Central Park from 1944 at 8 days? That's why I listed 1944 as the start of the super hot cycle that ended in 1955.  1944-1955 is twelve years and 5 of those summers were extremely hot.  It mirrors the 12 year period from 1991-2002 which also had 5 really hot summers.

Maybe climate change will add more to this intense heat and the next time we get this very hot 12 year cycle climate change superimposed on top of this 12 year cycle will break the records that were set in both those cycles?

The records I'm looking at are:

1944 8 consecutive 95+ days NYC

1948 3 straight days of 100+ at JFK

1949 5 days of 99+ at NYC  (the 8 days of 100+ at EWR was already exceeded in 1993, in the next very hot cycle).

1953 a 12 day and a 7 day super heatwave at NYC with 4 days of 100+ evenly split between the two superheatwaves, which included the highest temperature ever recorded in September at 102.

1955 16 95+ days at NYC and 14 95+ days at LGA

 

Second hot cycle

1991  39 90+ days at NYC

1993 39 90+ days at NYC (tied 1991), 3 straight days of 100+ at NYC during a 10 day super heatwave, 9 days of 100+ at EWR, including 5 in a row (beat the record from 1949 during the last very hot cycle)

1995 July had our area's highest heat index on record (at LGA) followed by the driest August on record with widespread wildfires

1999 Two super heatwaves of 9 and 8 days length in July, exceeded 100 areawide and set records for number of 90+ days in July

2002 Two super heatwaves of 8 and 7 days length in July and August

wow I wish I was alive then, this must have been absolutely amazing-- look at that 96 high on August 16 with 0.88 of rain, who said it can't get hot and rain a lot at the same time ;-)

The circulation patterns have changed since the 1950s. So areas east of the Hudson have more onshore flow influence and rainfall. So the most impressive records for heat in recent years have been found in NJ. 

We can’t use NYC to compare to those days since they changed how the measure temperatures in 1995 under the trees instead of out in the open in the 1940s and 1950s.

Incidentally where is Hightstown Chris? I had never heard of this town until you started posting this but they seem to have a treasure trove of data going back to the 1940s, including some of the best historically hot summers like 1955 which leads the pack with 8 days of 95+ on that list!

it's different dry vs wet.  I have a really bad mold allergy problem and I sneeze too much to be able to sleep if the air is really moist.

 

Just get a dehumidifier
