Based on trajectory most of the storms look to miss to our south 

it's raining here now!

[LibertyBell]

the last two days were truly historic.  I did a quick survey of local weather stations (the micronet does not save high low information, which is a drawback.)

the first and third weather stations in this list closely match my highs of 102.6 and 106.0 the last two days.

Park and TTN (of late) the coolest spots.

[SACRUS]

 

Doesn't look like we'll get midnight 90s in any of the metro sites and tomorrow falls short of 90.  EWR is still at 96 but dropping

this area has been the hot spot the last 2 days.  JFK if anything underdone on temperatures yesterday, there were widespread 105-106 temperatures across southern Queens and southern Nassau yesterday.

102 today is closer to reality, it bounced back and forth between 102 and 103 here today.

Lightning from the storm out in the Atlantic is visible all the way from the north shore of LI, I initially thought it was much closer.

[donsutherland1]

Prior to 2025, here are the frequencies of 80 or above lows and 90 or above highs in Central Park during summer.

The bugs are out tonight Don =\ The rain and these warm minimums must have a lot to do with it.

Are the temperatures going to stay above 80 most of the night? With a cold front coming through and rain falling you'd think they'd fall faster.

Is there any way to rank heatwaves the way we rank KU events? In terms of intensity, longevity, coverage of 90, 95 and 100 degree temperatures (both by area and by population affected), etc.?

 

[Snowlover11]

figures storms go up well east of here.

[steve392]

No rain by my house but some towns to my northwest while driving in got soaked good it looks like.  

 

76 and gorgeous outside.  What a relief!

All the sites held onto their 80 or above lows yesterday.

[doncat]

It will be cooling down but  today's am low of 79° is my warmest for the week.

[SACRUS]

 

 

82 / 70 clear.  Avoided the rain.  Winds going NNE as the onshore coolant commences.  Looks to fall short of 90 with that wind and overnight lows stayed in the low-mid 80 which should equal today's highs /maxes for the day.  Deep onshore / muck clouds with scattered storms / showers later tonight and Friday.   

Ridge pushes north this weekend and we have a warm-hot, humid and Florida style weekend in/out sun and heats up quickly but storms popping up Sat evening and Sun later. Enough sun gets the hot spots to 90, clouds otherwise keep it down.   Similar progression warm-hot / humid with storms possible Mon - Tue.  Dries out by the 3rd - 4th warm 80s - 90s.  Ridge builds west and next weekend 7/5 - 7/6 could be a bit unsettled pending on timing.  Ridge building heights and heat north and east later the week of the 8th.

6/26 - 6/27 : Onshore develops cooler, storms Thu night
6/28 - 7/2 : Warm-hot (in/out sun)  humid with storms chances each day - eveings (Sat / Mon focus)
7/3 - 7/4 : Drier - warm - looks great for the fourth 
7/5 - 7/7 : wetter / fronatal boundary along the coast
7/8 - beyond :   hotter , still wetter overall

This was the strongest heatwave in our area that was ever recorded during the month of June. We had widespread 103° readings from NJ to Baiting Holllow on Eastern Long Island with multiple 105° readings in Queens. This may be the first 103° ever recorded on Eastern Long Island.

So the list below is all the 103°+heatwaves since 1936 and the month which they occurred. There hasn’t been multiple 103°+ heatwaves in the same season before. I know that you really enjoy this type of heat. But I am hoping that this follows past examples and is the warmest we see for all of 2025.

The other thing on the list below is how these heatwaves have become earlier in the season. We haven’t one in August since 2006 and September since 1953.

103°+ heatwaves since 1936 and local maximum temperatures 

June 2025…..105°

June 2021…..103°

July 2012……104°

July 2011……108°

July 2010…..108°

August 2006…103°

July 2005….103°

August 2001….105°

July 1999…..104°

July 1995…..104°

July 1993…..105°

July 1977……104°

July 1966….107°

August 1955….103°

September 1953…..105°

July 1949…..105°

July 1948…..103°

July 1936….106°

Historical:

 

1888 - Residents of New York suffered through a record heat wave. Daily average temperatures were above 80 degrees for fourteen straight days. The heat wave was a sharp contrast to the severe blizzard in March of that year, which buried the city under nearly two feet of snow. (David Ludlum)

 

1930: Lightning struck the John B. King drillship in the St. Lawrence River, igniting a storage of dynamite onboard. The resulting explosion killed 30 people and injured 11 others. (Ref. Wilson Wx. History)

1931: Anchorage, Alaska: The temperature soars to 92 °F, their hottest reading of record to date.(Ref. WxDoctor)(David Ludlum)

1952: Record Maximum temperature for Richmond International Airport for the date and for June is 104 °F. (Ref. Richmond Weather Records - KRIC)

1952: Boston, MA recorded its highest temperature of 100 °F for June. (Ref. NOAA Boston Weather Events)

1954: Under calm winds and a bright sunny sky a killer wave rose suddenly from a placid Lake Michigan sweeping 8 unsuspecting fishermen off a breakwater to their deaths. The water level at Montrose Harbor surged more than 10 feet within a few minutes. The “seiche” was caused by an earlier squall on the lake. (Ref. Wilson Wx. History)

1957: Residents of Cameron, LA went to bed believing that they had plenty of time to evacuate the following morning in advance of what was then Category 2 Hurricane Audrey. Official bulletins from the U.S. Weather Bureau stated that the storm would not come ashore until late the next day. They would be very surprised the next morning to find water covering much of their parish as a 12 foot storm surge was already impacting the area and the center was just offshore. Also, Audrey had intensified rapidly during the night, with the central pressure dropping 35 millibars from the last reconnaissance fix during the day. Winds correspondingly increased to 145 mph and the storm surge rose from an expected 5 to 8 feet to a devastating 12 feet and higher. Additionally, the forward movement of the hurricane increased from 6 to 15 mph, and as residents were told that the hurricane would not strike until the following afternoon. 390 people died and another 192 were missing.

1957: The high temperature at Palm Springs, CA hit 121°; tying their highest temperature set on 6/24 & 6/29/1994. (Ref. Wilson Wx. History)

1979: Temperature failed to reach 90° in Washington, DC. during first 6 months of 1979 this hasn't happen since 1886.(Ref. Washington Weather Records - KDCA)

1980: Severe storms in South Dakota with winds over 60 mph were reported in at least 10 separate counties. The hardest hit area was Mitchell where 100 mph winds slammed into the city wiping out trees, blowing out windows, and damaging the airport. Damage in Mitchell alone exceeded $200,000 dollars. Several locations across the Plains endured record breaking heat including: Dallas (DFW), TX: 113°, Wichita Falls, TX: 113°, Dallas (Love Field), TX: 112°, Wichita, KS: 109°, Waco, TX: 107°, Grand Junction, CO: 106, Houston, TX: 102°, San Antonio, TX: 102°, North Platte, NE: 101°, Corpus Christi: 100° andVictoria, TX: 100°.(Ref.

1988 - Thirteen cities in the southeastern U.S. reported record high temperatures for the date. In Montana, the record high of 102 degrees at Billings, MT, was their fifteenth of the month, and the high of 108 degrees at Glasgow MT equalled their record for June. Thunderstorms in the Atlantic Coast Region produced wind gusts to 102 mph at Tall Timbers MD. (Storm Data) (The National Weather Summary)

1989 - Thunderstorms produced severe weather from the Central Plains to the Middle Mississippi Valley. There were 129 reports of severe weather during the day and night. Thunderstorms in Kansas produced wind gusts to 90 mph at Liberal, and hail four inches in diameter at Quinter. Thunderstorms in Wisconsin spawned a tornado at Lake Delton injuring four persons. Lightning struck and killed a woman at Junction City, KS, who had gotten out of her car to photograph the lightning. (The National Weather Summary) (Storm Data)crossed northern Mexico), began to spread heavy rain into southeast Texas and southwest Louisiana. (The National Weather Summary)

1993: Two miles northwest of Little Sioux, Iowa golf ball size hail completely covered the ground and strong winds caused this hail to drift. The most significant hail damage occurred in Shelby County. Here, a thunderstorm dropped golf ball to softball size hail in a swath about two miles wide and 20 miles long. Baseball size hail covered the ground six miles north of Harlan. Reports of 75% crop destruction were common within this hail swath. (Ref. Wilson Wx. History)

Wilson Wx. History)

1998: Severe thunderstorms crossed the Niagara Frontier, the western southern tier and eastern Lake Ontario Region in New York during the early morning hours. The thunderstorms produced large hail and damaging winds which downed trees and power lines. One-inch hail fell in Batavia. Five to six inches of rain fell in a 200 square mile area sending small streams out of their banks causing several million dollars worth of property damage in the Villages of Arcade and Gowanda. Erie, Wyoming and Cattaraugus counties were declared state and federal disaster areas. In Arcade, 37 were rescued from treetops and rooftops by the Water Rescue Team. Over 130 homes were damaged in Arcade. (Ref. Wilson Wx. History)

1999: 15 inches of rain fell, most of it between 9 PM and midnight, over the Schriever, LA area as thunderstorms continuously redeveloped and “trained” over the same areas. Roads were underwater and about 100 homes were damaged.
The most damaging hailstorm to ever strike Cheyenne County, Wyoming occurred. Hail up to baseball size and winds up to 80 mph devastated much of the western part of the county. Damage to property and crops exceeded $26 million dollars. (Ref. Wilson Wx. History)

2002: Phenomenal flash flooding struck Fort Wayne, IN as thunderstorms developed and re-developed directly over the city for several hours during the evening Times Corner reported 8 inches of rain in three hours. Spy Run Creek rose 9 feet in 8 hours to an all-time record level of 12.3 feet. Three inches of rain fell in 90 minutes. (Ref. Wilson Wx. History)

2006: The maximum rain in 24-hour period was 5.61 inches from 5 AM on June 25th to 5 AM of the 26th at Annandale, VA. This was very near the record of 5.66 inches set on October 7th and 8th 2005. (Ref. Annandale Weather Records - KDCA)

2008: In addition to the 3 confirmed tornadoes, multiple reports of large hail were received over Corson and Dewey Counties, including some to the size of baseballs near the communities of McLaughlin and Isabel. The large hail broke out many home and vehicle windows and damaged many roofs in Dewey, Corson, and Sully Counties. Near Sutton Bay on Lake Oahe, where a wind gust of 92 mph was recorded but close to the intersection of Highways 1804 and 175th street several Western Area Power Administration electrical transmission towers were completely collapsed. This is consistent with wind speeds ranging from 130 to 140 mph. Also of great significance during the event was the peak wind speed of 124 mph recorded at the Onida airport. This wind speed is the strongest wind gust ever measured in the Aberdeen County Warning Area and the 4th strongest wind speed ever reported in South Dakota. (Ref. Wilson Wx. History)
