Or 18z..I guess 12z finally did run

[lee59]

Looks like forecast highs have come down a tad. We will see.

[Dan76]

That will change a couple times 

[jm1220]

Thu and especially Fri look like the days that the coast could really rocket. 850s reach 24-25C on Fri so that should be the peak of the heat. Tue looks like strong onshore flow and maybe even Ambrose Jet. Wed the higher 850 temps over 20 move in but also maybe some storms along the periphery of the ridge. Sat-Sun the ridge looks to weaken and start to break down. 

[boxingdayblizzard]

Don’t see any thunderstorms or good rain to break the heat

Seems like 2006 / 2002 progression so far.  We'll have to see the extent of the ridge in the 7/8 - mid month period.

Record heat every month starting back in March with new monthly maxes tied or set in May.

Was there any explanation as to why the National weather service website was down for like 8 or 10 hours? I found that odd, to say the least.

I don't know how true it is, but i saw on Twitter/X that an Iraqi or Iranian hacker group took down the nws website as well as the ecmwf website

74 / 65 clear.  Nice day on tap warm / dry - perhaps an isoloated shower or storm later low - mid 80s.  The heat is on Tue - Sun/Mon peaking Wed - Sat (7/1 - 7/4) with upper 90s / low 100s in the hottest spots.  Ridge position key and storms or MCS around the periphery of the 594 DM will bring isolated - scattered showers Fri - Sat - Sun but by no means a washout.  7/7 - 7/11 looks warm - hot with intense heat pulling back south and west, but still plenty of heat into theeas.  Looks like a trough in the 7/12 - 7/15 period to take us back to normal / below before the next roud of heat expands east right after mid month.

Historical:

 

1826: Thomas Jefferson made his last entry in his weather observation log on this date, just six days before he died. The weather held a fascination for Jefferson as he made regular weather observations. He bought his first thermometer while working on the Declaration of Independence and his first barometer shortly after that.

 

1878: The weather observer on top of Colorado's Pike's Peak noticed that a major storm remained stationary over South Park, some 50 miles away. The observer also noted that the whitened ground from hail could be seen until sunset. (Ref. Wilson Wx. History)

1899: A great flood occurred on the Brazos River in Texas. The flood waters reached a width of 12 miles and caused $10 million dollars in damage. (Ref. Wilson Wx. History)


1907: A tropical storm moved from the Gulf of Mexico to coastal North Carolina, where it dissipated. The remnants moved north and combined with a cold front moving in from the Ohio valley, producing two days of widespread severe weather through the 29th. In some areas, rainfall amounts ranged from 3 to 6.73 inches, producing flooding that exceeded the flooding of tropical storm Agnes in 1972. Thunderstorms also produced high winds, hail and tornadoes, including F2 tornadoes at Edgemont, PA where debris from a destroyed garage was carried three-quarters of a mile away. Eight people were killed, six by drowning in swollen streams or rivers.(Ref. Wilson Wx. History)

1931 - The temperature at Monticello FL hit 109 degrees to establish an all-time record for the state. (The Weather Channel)

1943" Minimum temperatures were above 75° from 23rd to 28th in Washington, DC and greater than 70°F on June 20th-29th. (Ref. Washington Weather Records - KDCA)
 

1954 - Hurricane Alice dumped as much as 27 inches of rain on the Lower Rio Grande Valley of Texas. The Rio Grande River at Laredo reached a level 12.6 feet above its previous highest mark, and the roadway of the U.S. 90 bridge was thirty feet below the high water. (David Ludlum)

1962: Flooding in Wichita Falls, TX resulted in a quarter million dollar loss in city equipment, man hours, and other city property. The official rainfall total at Sheppard Air Force Base was only 1.64 inches, but other reported rainfall included 2.60 inches in downtown Wichita Falls, and from 4.20 to over 5 inches at Charlie, in northern Clay County. An estimated 300 cars were stranded temporarily on highway 287 near Jolly, when sections of the highway were flooded by over two feet of water. (Ref. Wilson Wx. History)

1975: Near Kingsland, Ark.--Lightning struck and killed a 6-year-old and injured her aunt while they were on a family outing on the banks of the Saline River. (Ref. Lightning-The Underrated Killer.pdf)

1987 - Thunderstorms produced severe weather in the Ohio Valley and the Great Lakes Region, with reports of large hail and damaging winds most numerous in Ohio, Indiana and Michigan. Thunderstorms spawned four tornadoes in Michigan. A tornado near Clare MI was accompanied by softball size hail. In Colorado, an untimely winter-like storm blanketed Mount Evans with six inches of snow. (The National Weather Summary) (Storm Data)

1987: In Colorado, an untimely winter-like storm blanketed Mount Evans with six inches of snow. (The National Weather Summary) (Storm Data)
 

1988 - Alpena, MI, reported a record low of 39 degrees while Jackson, MS, equalled their record for the month of June with an afternoon high of 105 degrees. Thunderstorms in the central U.S. soaked Springfield MO with 3.62 inches of rain, a record for the date. (The National Weather Summary)

1989 - Thunderstorms produced severe weather in the Southern and Central High Plains Region. Thunderstorms in Colorado produced softball size hail at Kit Carson, while pea to marble size hail caused ten million dollars damage to crops in Philips County, CO. (The National Weather Summary) (Storm Data)

1990: A microburst wind estimated around 150 mph did extensive damage in the town of Streamwood, in the Chicago metro area in Illinois. At least $10 million dollars damage was done to 25 stores and industrial buildings. Radar and eyewitness accounts indicated no rain or thunderstorms in the immediate vicinity of the area at the time.  (Ref. Wilson Wx. History)

1993: Flash flooding rolled across southeast South Dakota and into northwest Iowa. A phenomenal 6 to 7 inches of rain fell in Dickinson and Emmett Counties during a 3 to 4 hour period. The Des Moines River rose several feet in just a few hours. Ocheyedan received 3 inches in just 45 minutes and Allendorf picked up 2.80 inches in 30 minutes. Many locations in northwest Iowa reported winds in excess of 60 mph, with some locations clocking speeds of 70 to 80 mph. Several tornadoes were also spawned during the evening in Emmett County in the Ringsted area, 3.50 inch hail fell and baseball size hail covered the ground just north of Estherville. Millions of dollars in damage was caused from the thunderstorms across the area.

1993: No river traffic was moving on the 585 miles of the Mississippi River from St. Paul, MN to Cairo, IL and on 535 miles of the Missouri River from Sioux City, IA to the point it joined the Mighty Mississippi. More than 5, 000 loaded barges were stranded. For the first time in history, major floods came down both rivers at the same time. (Ref. Wilson Wx. History)

1994: Persistent extreme heat in the Southwest as Arizona 128°F at Lake Havasu City and Nevada 125°F at Laughlin set all-time record high temperatures on the same date. (Ref. Lowest and Highest Temperatures for the 50 States)


1998: "The Corn Belt Derecho of 1998" in the following states NE, IA, IL, IN, KY. A derecho which originated in far southeast South Dakota moved across Illinois during the afternoon and evening and continued as far east as Ohio the next morning. Every county in central Illinois sustained some damage, as these severe thunderstorms passed. Winds gusted in the 60 to 80 mph range, with some localized microbursts producing winds more than 100 mph. Significant damage occurred in the microburst areas, including the towns of Morton, McLean, LeRoy, and Tolono. In Tolono, 22 cars of a southbound 101-car Illinois Central freight train were blown off the tracks. It was unknown how many vehicles were picked up by the wind, but 16 cars were turned over, and another six derailed but remained upright. The train was en route to Centralia from Chicago with a load of mixed freight, including plastic pellets and meal. The freight cars empty weighed about 60,000 pounds, while a full one weighs about 260,000 pounds. Overall, 12 people were injured, and damage was estimated at around $16 million.


2003: Tropical Storm Bill made landfall south of Houma, LA with top winds of 60 mph, spreading a six foot storm surge across the low lying portions of the Louisiana Coast. For the second time in two years, the town of Montegut, LA was flooded after the town’s protection levee was breeched. Bill dumped 5 to 8 inches from Louisiana to Alabama. A tornado at Reserve, LA injured four people.
(Ref. Wilson Wx. History)

2005: Heavy rains of 3 to 7 inches fell across far eastern Brown, western and northern Day, and most of Marshall Counties in South Dakota during the early morning and again in the afternoon hours. One location measured 5 inches of rain in two hours. In Day County, 30 roads were washed out and 15 bridges were damaged. Some rainfall amounts include 5.04 inches in Britton, 3.34 inches north of Columbia, and 2.08 inches at Aberdeen. Total June rainfall for some locations in Marshall and Day Counties was between 11 and 12 inches. The flooding continued into early July before receding by July 10th. (Ref. Wilson Wx. History)

2012: The maximum temperature today was 103 °F at the Richmond International Airport a new record maximum temperature for the date. The old record was 101 °F in 1980. (Records since 1897) The maximum at the West Henrico Co. - Glen Allen station was 102 °F at 4:20 PM. It was the hottest day here since July 22, 2011 when it was also 102 °F. Friday's derecho, a widespread and long-lived violent thunderstorm complex, affected millions of people from Chicago, Ill., to Washington, DC. Strong winds, in many cases in excess of 70 mph, downed numerous trees and power lines from Illinois to Maryland. Over 2 million people were left without power. Winds with derecho -- 86 mph at Wintergreen Mt., 80 mph at Roanoke Airport 71 mph, Dulles 70 mph at Reagan, National 59 mph in Richmond International Airport and only 37 mph in West Henrico Co. - Glen Allen VA.

If we can make it to 103 here, having a low of -7 earlier this year, the 110 degree range is one of the largest I can think of since I've been tracking.

[SACRUS]

Up to 87 quickly today

[weathermedic]

Got this message from work. NYC Emergency Management has implemented their flash flood emergency plan due to thunderstorms. I don't see any thunderstorms in the forecast for NYC today or tomorrow and a 20% chance on Wednesday.

Damn! If that’s true, that’s kinda bananas. Was going to Gilgo and wanted to see about any possible rip currents during the morning and the site was down. And then when I saw the heat models being posted in this thread for this week, when we got back, went to NWS and saw it was still down. 

[steve392]

Pulled into work and winds are blowing. Kinda makes the heat slightly tolerable.  But I am watching what looks like a storm try to build to my southeast, probably south of Brooklyn and moving west/southwestish. 

 

How are we supposed to attach/add pics if the allowable size of 10kb it's reached 30 years ago?  Lol jc

Stop with the political stuff. Please and thank you.

Radar looks clear. Seabreeze front very prominent on radar and is splitting Long Island almost exactly in half running east to west.

90 here right now, so the long heat wave starts.

It isn't political if someone is commenting on (with actual caveats) the reason why a website went down. It isn't opinion based, or leaning to some kind of political affiliation.

As someone who does not want politics in this forum either, this does not meet the criteria for that by a long shot, and you need to check yourself. Being hypersensitive does not serve our goals either.

[FPizz]

88 currently.  Trying to move some flowers around today for my irrigation system since we are going away tomorrow and I'll have no one to water by hand.

88/56 here.

The new sensor for my PWS has been performing well, didn’t really have a temperature issue until recently but the humidity had been running slightly high for years. It’ll be interesting to see if I still get the same nuclear heat indices during high-end heat waves when a sea breeze pushes through.

A warming trend is under way. The warmth will continue to build through the remainder of June before culminating in a severe heatwave to start July. 

The heat could rival that of early July 1966. Much of the region will likely experience its highest temperatures so far this summer with maximum temperatures peaking in the 100°-105° range. Some locally hotter temperatures are possible. Most of the Mid-Atlantic and southern New England areas will see temperatures reach 100° or above during the height of the heatwave. Boston, Burlington, Philadelphia and Washington, DC could challenge their all-time records.

The ENSO Region 1+2 anomaly was +3.1°C and the Region 3.4 anomaly was +1.8°C for the week centered around June 24. For the past six weeks, the ENSO Region 1+2 anomaly has averaged +2.60°C and the ENSO Region 3.4 anomaly has averaged +1.37°C. The ongoing El Niño will continue to strengthen through the summer.

The SOI was -13.64 today. 

The preliminary Arctic Oscillation (AO) was +1.326 today. 

Based on sensitivity analysis applied to the latest guidance, there is an implied near 100% probability that New York City will have a warmer than normal June (1991-2020 normal). June will likely finish with a mean temperature near 73.2 (1.2° above normal). 

Supplemental Information: The projected mean would be 1.8° above the 1981-2010 normal monthly value.
