1788: Hail piled up to a depth of 34 inches at Canterbury, CT. The melting ice caused significant flooding. (Ref. Wilson Wx. History)

1816 - Frost was reported in low places throughout New England. (David Ludlum)

1886: Sleepy Eye, Minnesota: Nearly every home in the small community are moved off its foundation by the severe thunderstorms which come in the night. Across Swift and Brown Counties, the storms produce high winds and intense hail. (Ref. WxDoctor)

The Magic City received 8.84 inches of rain in 24 hours, which is their all-time record. Another hurricane would make landfall near Pensacola, FL later in the month and dump more heavy rain on Birmingham, where the monthly rainfall total reached 20.16 inches, a monthly record that still stands. (Ref. Wilson Wx. History)

1936: The greatest heat wave on record gets underway across Michigan. Grand Rapids saw high temperatures at or above 100° on six of the next seven days, including an all-time record high of 108° on the 13th. Lansing, MI maximum temperature was 101° on the 14th. Temperatures soared to 105° at Toronto, Ontario Canada on three consecutive days through the 10th. (Ref. Wilson Wx. History)

1950 - The town of York, NE, was deluged with 13.15 inches of rain in 24 hours to establish a state record. (The Weather Channel)

1975 - Three people were killed and six others were injured when lightning struck a walnut tree near Mayo, FL. The nine people were stringing tobacco under a tin shed when the bolt hit the nearby tree. (The Weather Channel)

Many record low temperatures were set including: Alpena, MI: 38°, Youngstown, OH: 44°, Muskegon, MI: 45°, Cleveland, OH: 45°, Detroit, MI: 45°, Pittsburgh, PA: 45°, Grand Rapids, MI: 46°, South Bend, IN: 47°, Buffalo, NY: 47°, Chicago, IL: 48°, Columbus, OH: 49°, Dayton, OH: 49°, Erie, PA: 50°, Indianapolis, IN: 51° and Cincinnati, OH: 51°. (Ref. Wilson Wx. History)
 

1987 - Thunderstorms in the central U.S. produced wind gusts to 90 mph at Waterloo, IA, 6.38 inches of rain at Tescott, KS, and twenty-five minutes of ping-pong ball size hail at Drummond, OK. (The National Weather Summary) (Storm Data)

1988 - Thirty cities in the north central and northeastern U.S. reported record high temperatures for the date. Beckley, WV, equalled their all-time record with a high of 93 degrees. Afternoon and evening thunderstorms spawned seven tornadoes in Adams and Logan counties of eastern Colorado, and hail caused 2.3 million dollars damage in Adams, Logan and Washington counties. (The National Weather Summary) (Storm Data)

1989 - Sixteen cities in the central and western U.S. reported record high temperatures for the date. The high of 103 degrees at Denver, CO, equalled their record for July, and a 110 degree reading at Rapid City, SD, equalled their all-time record high. Denver reported a record five straight days of 100 degree heat, and Scottsbluff, NE, reported a record eight days in a row of 100 degree weather. (The National Weather Summary)


1991: DCA high temperature was 97° - severe thunderstorms with winds to 62 mph; 0.95 rain in only 15 minutes and one-inch hail in parts of Northern Virginia.  (Ref. Washington Weather Records - KDCA)

1992: Severe thunderstorms produced a very long downburst at Concordia, KS. Peak one minute sustained winds reached 108 mph at Concordia Airport and exceeded 60 mph for over 20 minutes. Six people were injured and damage was estimated at $25 million dollars.  (Ref. Wilson Wx. History)

1993: New record high temperature was recorded at DCA of 100° and a minimum of 78°. The old record was 98° set in 1890.
(Ref. Washington Weather Records - KDCA)

1993: Iowa: A wild weather night in the middle of the Great Flood of 1993 across Iowa as the State records its 37th day of rain in the last 40 days. Many tornado sightings reported. Manilla, Iowa records 7.5 inches of rain; 7.83 inches in Jefferson.  Massive flooding rocked portions of eastern South Dakota. Residents were cleaning up from tremendous flooding which occurred from July 3rd to July 7th. Flash flooding resulted from thunderstorms which moved across southeast South Dakota dumping 3 to 6 inch rains on already saturated ground. (Ref. WxDoctor)  (Ref. More Information on This Storm)

1999: One of the worst flash flood events in Las Vegas, NV history occurred on this date damaging roads and buildings, sweeping away vehicles and bringing the entire city almost to a standstill from late morning through late afternoon. Thunderstorms formed over the elevated west side of the valley and began dumping heavy rain between 10 and 11 AM PDT. The storms slowly drifted to the east producing rainfall amounts over 1.5 inches across a substantial part of the metro area and some localized amounts topping 3 inches. Electricity was knocked out for a few hours to 2,500 customers and some gas lines were broken by the force of the water. An estimated $25 million dollars in damage occurred to both public and private property. On July 20th, President Clinton declared the event a federal disaster. (Ref. Wilson Wx. History)

2003: What may be the world's highest dew point temperature was recorded at Dhahran, Saudi Arabia, in the Persian Gulf. A dew point of 95 degrees was recorded at 3 PM while the air temperature was 108 degrees. The apparent temperature at that time would have been 172 degrees.

2006: In Tonopah, Nevada a man and his son stepped out of their pickup truck to check the tires. Lightning struck, killing the boy and throwing the father to the ground. The boy's mother and sister were in the pickup and were not hurt. (Weather Guide Calendar with Phenomenal Weather Events 2007 Accord Publishing, USA)

2008: A strong microburst produced straight line wind damage in the Hurricane Deck and Osage Beach areas of Camden County in central Missouri. The winds were estimated at 80 to 90 mph and did extensive damage to docks and boats in the area. (Ref. Wilson Wx. History)


2009: A tornado passed through the city of Dickinson, ND, on the far south side, mainly just south of the Heart River. From their eye witness accounts, and from video obtained by the Dickinson Police Department, it is likely that this was a rain-wrapped tornado, and very difficult if not impossible to see. The tornado occurred before sunset, yet it was described as being as dark as night during the event. Over 450 structures were damaged, of which nearly 100 were declared completely destroyed or beyond repair. Numerous vehicles were damaged or destroyed, some were on their roofs. From that it was determined that peak wind speeds in the tornado were on the order of 150 mph. (Ref. Wilson Wx. History)

These are the two things I remember the most about 1993.  St Louis was flooded out that year while we were baking in intense relentless heat all summer long.

 

 

2003: What may be the world's highest dew point temperature was recorded at Dhahran, Saudi Arabia, in the Persian Gulf. A dew point of 95 degrees was recorded at 3 PM while the air temperature was 108 degrees. The apparent temperature at that time would have been 172 degrees.

 

and we thought our dew points were bad lol

i don’t think this is physiologically true but 80/78 feels worse to me than 102/80.  my body is a nucleation point, i am becoming a giant drop of water.  i am setting my apple watch workout to Outdoor Swim

80/78 is a hell of a lot worse than 102/80 and I've experienced BOTH.  The reason 80/78 is worse is because it's usually cloudy and oppressive.  102/80 gives you sunshine which makes it feel drier and less oppressive.

The sun is a very powerful friend.

We should all hit 90+ today, except Central Park of course.

 

Think the park may get there today as well for their 5th (trailing) 90 degree day if not and other do, itll further to distort the perception for the city/mtero area.  Need to take a look as TTN seems to be running cooler than surrounding sites since 2020.  Not sure.

Windhoek Nambia broke their all time record low 2 times over for June in a span of a week but its fairly mild now in SA and southern Africa after it had been cold for a couple of weeks 

Namibia also has some of the lowest light pollution of anywhere on the planet.  The other place is the Australian outback.

I'd like to know how bad things have to get before people are like fcck it just do the stratospheric aerosol injection. 

I would have already dropped planetary temperatures down to pre industrial levels if I was king of the world. 

To be fair, I would also be massively transitioning to clean energy and simultaneously be slowly easing off the aerosols over time. 

It's scheduled to start in 2030.

Through July 7, Bridgeport, Islip, JFK Airport, and White Plains are in the top 3 for the number of 70° or above lows to date.

Bridgeport: 8 days (tied second with 1974 and 1999)
Islip: 9 days (tied third with 2002)
JFK Airport: 12 days (third)
White Plains: 7 days (third)

The combined figure of 36 days also ranks as the third highest. Eight of the ten highest figures through July 7 have occurred since 2000, including three since 2020 (2021, 2024, and 2025).

 

ugh, JFK was built on  a SWAMP.

I don't know why they have to be politically correct and call it wetlands, there is nothing good about them, they smell bad, and are full of toxic bugs, they are definitely a SWAMP and should be drained.

SMQ set their all-time highest dew point temperature of 83° back in June. They just came in 2nd with a dew point of 81 yesterday. So a record amount of atmospheric moisture around the world leading to the numerous extreme flooding events. The SPC HREF has a 2”-3”+ max potential with the better storm coverage for later today.

I see a lot of potential in converting all this useless water vapor into drinking water.  I read that the first projects to do this have already begun.

H20 water vapor is as much of a greenhouse gas as CO2 is, so reducing it would benefit us all.

Perhaps it has a small impact. The coefficient of determination was very low (0.026).

Don what are the frequency of 100+ degree highs as a whole for the urban reporting sites (NYC,EWR,JFK,LGA) for the July 24-30 period? I imagine EWR has a few, but do any of the others have any? It's particularly impressive that NYC doesn't have any especially considering their POR goes back to the 1860s!!
