Tens of millions in US face dangerously hot weather in rare June heatwave
Tens of millions of people across the midwest and east braced on Sunday for another sweltering day of dangerously hot temperatures as a rare June heatwave continued to grip parts of the US.
Most of the north-eastern quadrant of the country from Minnesota to Maine was under some type of heat advisory on Sunday. So were parts of Arkansas, Tennessee, Louisiana and Mississippi.
The temperature had already reached 80F (26.6C) in the Chicago area by 7.30am on Sunday, according to the National Weather Service. Forecasts called for heat indices of between 100 and 105F.
The heat index in Pittsburgh was expected to top 105F. The temperature in Columbus, Ohio, was 77F at 8.30am. Highs there were expected to reach 97F with a heat index around 104F.
Forecasts called for a heat index of 100F in Philadelphia on Sunday, with a 108F heat index on Monday.
The city's public health department declared a heat emergency starting at noon on Sunday and ending on Wednesday evening. Officials directed residents to air-conditioned libraries, community centers and other locations, and set up a 'heat line' staffed by medical professionals to discuss conditions and illnesses made worse by the heat. At Lincoln Financial Field, officials said each fan attending Sunday's Fifa World Cup match would be allowed to bring in one 20oz plastic bottle of water.
Forecasters warned the heat index in Cromwell, Connecticut, would reach 105F on Sunday, which could make life brutal for golfers Tommy Fleetwood and Keegan Bradley as they compete during the final round of the Travelers Championship.
Elly De La Cruz, a Cincinnati Reds shortstop playing against the Cardinals in St Louis, and Trent Thornton, a Seattle Mariners reliever facing the Cubs in Chicago, got sick on Saturday while playing in the extreme heat.
Sunday marked the second straight day of extreme heat across the midwest and east coast. Heat indices on Saturday hit 103F in Chicago and 101F in Madison, Wisconsin, turning that city's annual naked bike ride into a sticky and sweaty affair.
Lynn Watkins, 53, is the director of Sacred Hearts daycare in Sun Prairie, a Madison suburb. She said that she tried to sit outside on Saturday to grill but it was so hot she had to go inside. She plans to cancel all outdoor activities at the daycare on Monday with highs around 93F forecast.
'I can't stand being outside when it's like this,' she said. 'I just want to sit in my air conditioning.'
Minneapolis baked under a heat index of 106F. The actual temperature was 96F, which broke the previous record for the date of 95F set in 1910, according to the weather service.
The heat is expected to persist into the coming week, with the hottest temperatures shifting eastward. New York City is expected to see highs around 95F on Monday and Tuesday. Boston is on track for highs approaching 100F on Tuesday, and temperatures in Washington DC were expected to hit 100F on Tuesday and Wednesday.
Meteorologists say a phenomenon known as a heat dome, a large area of high pressure in the upper atmosphere that traps heat and humidity, is responsible for the extreme temperatures.
Mark Gehring, a National Weather Service meteorologist in Sullivan, Wisconsin, said this level of heat is not uncommon during the summer months in the US, although it usually takes hold in mid-July or early August. The most unusual facet of this heatwave is the sheer amount of territory sweltering under it, he said.
'It's basically everywhere east of the Rockies,' he said, referring to the Rocky Mountains. 'That is unusual, to have this massive area of high dewpoints and heat.'

Son begs his mom to stop trying to fight fellow LSU fan in embarrassing College World Series viral clip
One LSU fan took the term 'Tiger mom' to a whole new level during Sunday's College World Series finals. LSU took on Coastal Carolina in Game 2 of the College World Series in Omaha Sunday but some Tigers fans appeared to forget who their rivals were as they turned on each other. In a now viral video, a young boy was left thoroughly embarrassed by his mom when she tried to spark a fight. The woman, wearing a bright yellow dress, was captured shouting at a man in an LSU football jersey. She wildly gestured at him, screamed the odd obscenity in his face, and even attempted the haul herself over the rows of seats separating the two. Thankfully for the other fan, another man, who appeared to be her husband, managed to hold her back. It is unclear what triggered the furious reaction, but the man appeared unfazed by the crazed woman as he just laughed in response to her rant. Hey fighting Tigers — OMAHA LSU Jesus (@LSUJesus) June 22, 2025 Other spectators around them watched on shocked, but it was her son that appeared to be the most stunned. The youngster, who was wearing former Tiger Dylan Crews' jersey, could be heard pleading with her to stop. Despite his desperate begging, the woman only began to calm down when another older woman approached her in an attempt to diffuse the situation. And it wasn't only in the stands where tensions were spilling over. Coastal Carolina coach Kevin Schnall and first base coach Matt Schilling were ejected in the bottom of the first inning. Walker Mitchell was at bat with two outs and Sebastian Alexander had just stolen base when Schnall went to the top steps of the dugout, gestured at plate umpire Angel Campos with three fingers and began shouting at him. Campos signaled Schnall's ejection, prompting the coach to charge out to argue. Schilling then was thrown out. It was not immediately known what Schnall was disputing. Associate head coach Chad Oxendine took over Schnall's duties. Coastal Carolina needs a victory to stay alive in the best-of-three series, which LSU leads 1-0.

Mets option slumping C Francisco Alvarez to Triple-A
June 22 - Once a highly touted prospect, New York Mets catcher Francisco Alvarez was optioned to Triple-A Syracuse on Sunday in the wake of his offensive struggles this season. Alvarez, 23, baseball's No. 1 prospect in 2022 who hit 25 home runs as a rookie in 2023, is hitting just .236 with three homers and 11 RBIs in 35 games this season. In a corresponding move, the Mets recalled Hayden Senger to serve as the backup to starter Luis Torrens. After making a splash as a 21-year-old rookie, Alvarez has been hampered by multiple wrist and hand injuries and regressed last year. In parts of four seasons with the Mets since debuting in 2022, Alvarez is a .223 hitter with 40 homers and 122 RBIs in 263 games. The 28-year-old Senger made his major league debut this season with the Mets, appearing in 13 games and hitting .179 in 28 at-bats. --Field Level Media

Marlins deliver timely hits, win series over Braves
June 22 - Otto Lopez had two hits and a pair of RBIs and Kyle Stowers homered to help the Miami Marlins post a 5-3 rubber-game victory over the visiting Atlanta Braves on Sunday afternoon. Xavier Edwards went 3-for-4 with an RBI and Sandy Alcantara (4-8) threw six innings of six-hit, three-run ball, while striking out four and walking two. Ronny Henriquez allowed Alex Verdugo's leadoff single in the ninth before getting Michael Harris II to ground into a double play and striking out Sean Murphy for his second save of the season. Miami also recorded its first series win over Atlanta since September 2023. Bryce Elder (2-4) allowed five runs on 10 hits in 5 1/3 innings, striking out four and walking one for the Braves, who followed a three-game sweep of the New York Mets with a series loss in Miami. Ronald Acuna Jr. and Ozzie Albies each went 2-for-4. After doubling on the game's first pitch, Acuna advanced to third on Matt Olson's flyout and scored on Austin Riley's single to left. Stowers' 11th home run of the season in the bottom of the second knotted the score at 1-1. The Braves reclaimed the lead in the third, as Acuna's single and Olson's walk were followed with Drake Baldwin's two-out RBI single. Miami pulled even again in the bottom of the third, as Edwards walked and stole his 14th base of 2025 before scoring on Lopez's single to center. The Marlins grabbed the lead in the fifth as Jesus Sanchez tripled and Lopez singled. With two outs, Dane Myers singled in Lopez to make it 4-2. Atlanta got one run back in the sixth as Baldwin walked, Albies singled and Verdugo grounded out to get the visitors within 4-3. Miami padded its lead in the sixth as Nick Fortes doubled and reached third on Javier Sanoja's sacrifice bunt. Elder was replaced by Dylan Dodd, who allowed Edwards' RBI single to right. Anthony Bender relieved Alcantara in the seventh, throwing 1 1/3 scoreless innings. --Field Level Media
