Last June set the highest 500mb height record for our area since 1952. It came in ahead of 2018 and 2013. 500 mb heights have been steadily increasing over the years. 

 

 

How did they calculate regional , continental 500MB heights then ?  how large was the network of radiosondes and balloons then vs now?  I havwe to go ovack to the 2001 heat dome in August and the 2011, 2013 how did they stack both were >594 DM from my recollection .

No. The 500mb heights were lower back then. We just set the all-time 500 mb height record in June 2024 at 599dm for our area when we had the 100° heat last June. This time the magnitude of the heat and the duration of the ridge will be more impressive. Those older 100° heatwaves weren’t as long as the one experienced in July 2022 which ran 5 days.

Interesting how many balloons and radiosondes were deployed or utilized in 30s-40s and 50s to get regional or national 500MB observations.  Id argue those heat domes were just as high then with those readings.

78 / 57 and breezy

Tony wow, so maybe 2012 will be an analog to this summer? 2010-2013 had summers similar to what we might be about to embark on....

 

 

I am not sure about 2012 being good reference for this year - we'll see.  I was thinking more along the lines of a warmer 2024 and perhaps evolving towards years that favor a warmer-hotter August / early Aug - early Sep.  Thus current ridge may throw a wrench - its a crap shoot.

Isn't this what happened in the 1944-1955 when we had those 7-12 day heatwaves with 95+ and 100+ temperatures?

I know you're all about climate change, but that was a cyclic pattern we had from 1944-1955 and which repeated itself from 1991-2002, so maybe that cycle is returning?

 

We have had heat domes the last few years, the majority went north and caused an onshore flow at times.  Some of the more impressing heat domes were the 2013 ridge backing in and hooking with the continental ridge, the 2011 ridge and the 2001 early August ridge.  Im sure the years you mentioned had similar heat domes to this and the 2012, 1988, 93 ones.  

Look to get through June with no Tropical activity or systems on the Atlantic side

Eric pumping the moisture feed into NM and the Upper Midwst wet the next week.   Next meanigful rain shot Sat night (isolated mainly north) and Wed pm / evening.

Historical:

1682 - A major tornado ripped through southwestern Connecticut, passing through Stratford, Milford, and New Haven, and then into Long Island Sound. (Sandra and TI Richard Sanders - 1987)

1921 - Circle, MT, received 11.5 inches of rain in 24 hours, a record for the state. The town of Circle received a total of 16.79 inches of rain that month to establish a rainfall record for any town in Montana for any month of the year. (The Weather Channel)

1928 - A farmer near Greensburg, KS, looked up into the heart of a tornado. He described its walls as rotating clouds lit with constant flashes of lightning and a strong gassy odor with a screaming, hissing sound . (The Weather Channel)

1964 - A squall line producing large hail swept through central Illinois. A second squall line moved through during the early morning hours of the 21st, and a third one moved through shortly after dawn. The series of hailstorms caused nine million dollars damage. Hailstones as large as grapefruit caused heavy damage to trees, utility lines, crops and buildings. The thunderstorms also produced as much as five inches of rain in an eight hour period. (David Ludlum)

1987 - Thunderstorms prevailed east of the Rockies, producing severe weather in the Central High Plains Region. Thunderstorms spawned four tornadoes in Colorado, and produced wind gusts to 70 mph at Goodland, KS. (The National Weather Summary) (Storm Data)

1988 - Thirty-eight cities in the central U.S. reported record high temperatures for the date. Afternoon highs of 97 degrees at Flint, MI, and 104 degrees at Chicago, IL, equalled records for the month of June. Thunderstorms in North Dakota produced baseball size hail near Kief, and wind gusts to 100 mph near McGregor. (Storm Data) (The National Weather Summary)

1989 - An early morning thunderstorm produced wind gusts to 61 mph at Pierre, SD, and the hot thunderstorm winds raised the temperature from 86 degrees at midnight to 96 degrees by 1 AM, and 104 degrees by 2 AM. Butte, MT, and Yellowstone Park, WY, reported snow that afternoon. (The National Weather Summary) (Storm Data)

1989:A meteorological "hot flash" hit Pierre. Descending air from collapsing thunderstorms caused the temperature in Pierre to warm from 86 degrees at midnight to 96 at one a.m. and to 104 at 2 a.m. Pierre's record high for the date of 105 degrees in 1974.

2001: Large hail driven by strong thunderstorm winds raked Denver International and front-range airports. Wind gusting to 54 mph along with hail as large as 2 inches in diameter punched at least 14 thousand holes and cracks in the flat roofs of several buildings at Denver International Airport. Also, 93 planes and hundreds of cars were damaged. About 100 flights had to be canceled stranding 1500 travelers. The Airport was completely shut down for about 20 minutes. The storm also damaged ground avoidance radar used to track planes on the ground to prevent collisions. Damage was estimated at 10 million dollars not counting the cost to the 93 airliners. The storm moved south and struck Watkins Colorado with hail as large as 2 1/2 inches in diameter and winds gusting to 60 mph. 

71 / 56 .  Breezy gorgeous day as the transition bridge to the strong ridge and building heat.  Hot Saturday through the end of the month with peak heat Sun - Wed /  with Mon-Tue hottest days area wide with century mark potential certainly in the hot spots but more area as well.  A nice weekend with storms looking to stay north and clouds clearing to allow sunday off to the races by the afternoon.    Storms Wed pm / night could spoil a 3 100 day streak.  Ridge rebuilds towards the 27th for next weekend 6/28 - 6/29. 

Beyond there overall warm - hot but looks like it could remain wetter with storm chances as ridge in west and along the coast keeps a more humid flow with building heat into the north and east.

Looks like dew points temps maxed out at 75/76 is the highest i see today.   Slowly dropping now into the upper 60s.

Ended with around 0.52

More storms moving into EPA - then to NWNJ

No you are confusing latest sunset and longest day. The longest day is always on the solstice. We peak tomorrow in Manhattan at 15h5m38s, we lose a second by the 21st. By the 26th we have lost a full minute.

 

Same as winter: https://sunrise-sunset.org/a/why-the-shortest-day-is-not-the-day-with-the-earliest-sunset-or-latest-sunrise.

exactly the sunsets around 8:30 till Jul 9th then slow decline - overall daylights minimal decline is attributed to later sunrise till then.

The longest day isn't really on the summer solstice, it's different days in different places depending on your latitude and some other factors. For us it's usually June 26th.

 

Longest day for us is 6/20

I think we have another week of slightly later sunsets. (Here in Cherry Hill it peaks at 8:32pm)

My wife, who is hoping for permanent EST would see a sunrise time as early as 4:30am! 

I know many wish to see permanent Standard time but I personally love the late sunsets. 

 

Yes the miniscule loss in daylight is attributed to sunrise till Jul 9th when minimal slow decrease in sunset begins.

Just hit 80 / 73 here  

We gain 0.05 seconds of daylight tomorrow to make the longest day of the year at 15H:06M
