Thanks. Looking forward to crossing Wyoming, Montana and the Dakotas off my list 

Enjoy. Montana will be one of the relatively cooler spots in a sea of warm this week. Good timing.  If this was the winter, then people on here would be commenting on how another cooldown missed to our west again.

Top 5 warmest summer so far for 70° minimums across the Northeast. High dew points and clouds keeping the lows up. Plenty of onshore flow with all the high pressure east of New England.

Was going to take my son to Legoland NY today. I am guessing that would be a poor decision looking at the models. Grr.

It's almost all outdoors from what I hear with minimal shade too (not that that will be an issue today). Think it is still worth it or wait for a better day? Might keep the lines down today...

1936 - Extreme heat prevailed across the central U.S. as severe drought raged from Texas to the Dakotas. Record high temperatures were established in sixteen states that summer, including readings as high as 120 degrees in the Great Plains Region. On this particular date, afternoon highs for 113 stations across the state of Iowa averaged 108.7 degrees. (David Ludlum)

 

1936: Collegeville, Indiana: The highest temperature ever reported in Indiana is 116 °F. The average temperature of 81.1° is the fifth highest ever recorded from June 27 to July 14th 1936. Extreme heat prevailed across the central U.S. as severe drought raged from Texas to the Dakotas. Record high temperatures were established in sixteen states that summer, including readings as high as 120 degrees in the Great Plains Region. On this particular date, afternoon highs for 113 stations across the state of Iowa averaged 108.7 degrees. (David Ludlum)

1954: East St. Louis, Illinois: The highest temperature ever reported in Illinois is 117 °F. Union, Missouri: The highest temperature ever reported in Missouri is 118 °F. (Ref. Lowest and Highest Temperatures for the 50 States) (Ref. Additional Temperatures Listed On This Link)

1957 - Hail, with some stones up to an inch in diameter, covered the ground to a depth of three inches ruining crops in the Bath area of New Hampshire. (The Weather Channel)

1966: Bakersfield, CA set a record low maximum of 90 °F. This is the only day of the entire year where Bakersfield has always had a high temperature of at least 90 °F in every year since records began in 1893. (Ref. Wilson Wx. History)

1970: A line of severe thunderstorms raced across southeast South Dakota into northwest Iowa causing extensive damage. The line of thunderstorms produced widespread high winds and large hail. The hail averaged quarter to hen egg size although some areas received stones the size of softballs and winds in excess of 70 mph were not uncommon. Apparently, the most extensive damage from the storms extended from Mitchell through Parker to near Beresford. Spotty areas reported 100% crop damage. In Lincoln County, the hail caused an estimated $8 million dollars in crop damage and $2 million dollars in property damage. In the town of Marion the hail was so large that it actually punched holes in some roofs.  Northwest Iowa didn't fair much better as the storms caused $5 million dollars in crop damage in Sac County. The storm was labeled the worst in 65 years in Sac County as 70 to 100 mph winds tore through the area. Amazingly enough almost every home in Sac City was damaged by the storm. Numerous structures also lost their roofs in Sioux county. Several fatalities in both South Dakota and Iowa were directly related to the severe weather.
(Ref. Wilson Wx. History)

1974: Connecticut--a 9-year-old girl was killed by lightning while camping. She was sleeping in a metal-frame tent.
Jefferson Davis Parish, La.--A man riding a tractor on his farm near Woodlawn was killed by lightning.    Near Redfield, Ark.--Lightning struck and killed a motorcyclist while he was standing in an open field. His two companions were slightly injured.  Owego, NY -- One person was killed and two were injured by lightning during an evening thunderstorm. No further details.
(Ref. Lightning-The Underrated Killer.pdf)
 

1987 - Severe thunderstorms in Iowa produced eight inches of golf ball size hail near Grafton, IA, completely stripping corn stalks in the area. Hail caused more than a million dollars damage to crops in Worth County and Mitchell County, and another million dollars damage in Ada County and Crawford County. Unseasonably cool weather prevailed in the Great Plains Region. Eight cities reported record low temperatures for the date, including Duluth, MN, with a reading of 37 degrees. (The National Weather Summary) (Storm Data)

1988 - Severe thunderstorms produced large hail and damaging winds in the Northern Atlantic Coast Region during the afternoon and evening hours. Thunderstorms also spawned a rather strong tornado near Westtown, NY, and drenched Agawam, MA, with four inches of rain. (The National Weather Summary) (Storm Data)

1989 - Afternoon and evening thunderstorms produced severe weather from eastern New Mexico to central Nebraska. One hundred soldiers were injured by flying debris and collapsing tents during a thunderstorm near Trinidad, CO. Thunderstorms in Colorado produced wind gusts to 77 mph at La Junta. Early morning thunderstorms produced torrential rains over parts of Louisiana, with 7.50 inches at Carencro, and 5.85 inches at Morgan City. (Storm Data) (The National Weather Summary)


1995: Boston, MA recorded 100F or higher for the 22nd time in history ant it was the first time since July 21, 1977, when 102 °F was recorded.  (Ref. NOAA Boston Weather Events).  July 14-15, 1995 "The Ontario-Adirondacks Derecho"....MI, ON, NY, VT, NH, MA, CT, RI  (Ref. For More Information)

History)

1996: Rockingham County, VA a 20-year-old male soccer player was struck and killed at the Rockingham County Fairgrounds. The soccer match had been called due to the storm, but the player had not yet sought shelter. (Ref. Lightning - Virginia Weather History)

1998: Rescuers searched for victims and survivors of flash flooding from the night before in parts of Tennessee. The training thunderstorms dumped 7 inches of rain in 6 hours in and around Lawrenceburg, TN. Bridges were washed out and vehicles swept away. At least two people were killed. (Ref. Wilson Wx. History)
 

1995: On the evening of Friday, July 14th, thunderstorms producing severe weather were occurring over Upper Michigan and adjacent portions of Ontario near Sault Saint Marie. By late evening the storms had evolved into a bowing line just northwest of the Mackinac Bridge. At 10:17 PM EDT, the thunderstorm gust front hit the bridge, and a gust to 90 mph was measured. Sustained winds of 80 mph continued on the bridge for ten more minutes. Thus began the intense "Ontario-Adirondacks Derecho" that would cause hundreds of millions of dollars’ worth of damage, several deaths, and many injuries as it raced southeast from the northern Great Lakes to the Atlantic coast. 

2002: A hot period in Billings, MT with a 108 °F maximum; the highs the previous two days were 107° and 106°. The record for the city is 112 °F on July 31, 1901. (Extreme Weather p. 275, by Christopher C. Burt) (Ref. Wilson Wx. History)

The minimums have set a new record across the area at spots like SMQ for the first half of summer. The average maximum was 7th warmest. But since last year featured the warmest average high, 7th place this year feels cooler by comparison. So it’s all relative to what we are getting acclimated to.

When our kids were little we would plan to do the outdoor stuff early and try to be done by 2. We usually avoided storminess and ate a lot of ice cream watching it rain after we were done outside.

I'd go-less people less sun and storms are likely after 4-5pm.

Exactly.  Anyone with solar can tell you productivity is way down from last year.  June 2025 I produced 500 kWh less than last year.  Month to date so far in July I've produced around 190 kWh less.

See all the sneaky ways climate change has impacted you lol

[Sundog]

@Brian5671, more rain, higher dewpoints and minimums, more clouds, overall higher temperatures AND @FPizz can't generate as much electricity?

Sounds like a nightmare bro, that last point about his solar panels not producing dividends for @FPizzkeeps me up at night.

You are correct with it mostly being outdoors and limited shade. If going there, I would recommend going early and getting out of there by mid-afternoon to dodge any possible showers/storms.

The idiots want to dim the sun but at the same time go solar.  Freaking morons.  

And no, last year was my best solar output in 13 years having panels and April of this year was the best month I've ever had.  So no, CC hasn't done anything, so wrong again for you. Practice what you preach and you'd know, but no one here does that posts 500 CC posts per day.

[Intensewind002]

79/77 out there right now, I wonder what the record is in our area for number of consecutive days to have a 70+ dewpoint

Good morning BW, is the cloud departure for the Pacific Northwest tied to the ongoing SST anomalies in the western Pacific? Thank you, As always …
