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.

There were 100 degree readings in NYC 2021

Records: Highs: EWR: 98 (1981) NYC: 96 (1994) LGA: 96 (1991) JFK: 92 (1962) Lows: EWR: 52 (1946) NYC: 52 (1927) LGA: 55 (1961) JFK: 52 (1965) Historical: 1794: A frost was reported at Mansfield, MA, repeating a previous occurrence made on May 17th.

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

Its all or more about the position center of the ridge, we have had record ridges in the past 10 years >600DM's.

You have to go back to 2015 for consecutive highs in the 60s for most of the board, that was the first week of Jue. June 2012 had a 3 day streak similar to this wthigh high near or below 70 around the same time.

Spotty light rain on this chilly April morning

No 100 degree days at LGA in 1988, 1987 nor 1994

1994 continued hot through July and August was close to normal for those west of the City - similar to 2024 i assume where onshore prohibited the heat from extending into eastern sections AT EWR there were 39 90 degree days. AT LGA 26 and NYC: 18 It also happened in 1987

Was much more pronounced west of the city during that June heatwave where EWR and C/N NJ hit 90 (9 of 10 days) with maxes of 100, 97, 98,99, 98 so the folks west of there felt it.

You should preface that with Central park in NYC - LGA hit 100 in June in 2021 (6/30).

Thu night into Fri morning

Astonishingly we had similar progression with the signal for the same period, last year which lead to the strong heat in NJ 6/20 - 6/27. The center of the ridge will be key as you detail if those east of NJ continue with the recent tendency for onshore or if its full blast westrlry
