Records are going up in flames - is there any break to America's current heat wave?

To call it a heat wave may be an understatement. But as June ends and July rolls in, a blanket of hot and humid weather is covering most parts of America with temperatures not seen since the end of the Great Depression.


The trend has scientists and meteorologists looking for answers.



AccuWeather's team of expert forecasters were describing the then upcoming heat wave as "unprecedented," "life-threatening" and "historic" as early as the middle of last week, and these descriptions have been accurate in the first days of the Northwest scorcher.


The weekend marked the beginning of the extended stretch of extreme temperatures. Portland, Oregon, a city that typically experiences temperatures in the middle to upper 70s in late June, soared to a staggering 112 degrees Fahrenheit on Sunday, breaking the all-time record high of 108 set just a day before. Prior to the current heat wave, the highest temperature ever recorded in the city was 107 set once in July of 1965 and twice in August of 1981.

Portland is also expected to obliterate its daily record high of 100 on Monday and possibly set an all-time high temperature record for the third straight day. AccuWeather is predicting a high of 113 on Monday, which would make it the hottest day ever recorded in the city.

The highest temperature ever recorded in the state of Oregon is 117, which was set in Umatilla on July 27, 1939.  June 28 - AccuWeather



And as Americans keep an eye on the mercury that continues to rise, there’s a lot of questions to be asked:


  • Is this a weather phenomenon?
  • Has climate change showed its hand?
  • Are these new temperatures the new normal for the summer months?
  • How can cities and communities adapt to these drastic conditions?
  • And is there any turning back these rising numbers?


If you’re a journalist looking to learn more about this topic, then our experts are here to help.

$787 a Month for a New Car? The Growing Cost of Getting Behind the Wheel

Buying a new car is becoming an increasingly expensive proposition for American consumers, with monthly loan payments now averaging a staggering $787. According to a recent DC News Now report, the average new-car loan is approaching $45,000, raising concerns about affordability, household debt and the long-term financial commitments consumers are making just to get behind the wheel. And the monthly loan payment is only part of the equation. Insurance premiums, maintenance, fuel and other ownership expenses can push the actual cost of driving considerably higher. For consumers already managing rising household expenses, the decision to purchase a vehicle has become increasingly complicated. Beyond the Sticker Price: What Consumers Need to Know Dr. Kashef Majid, Associate Professor of Marketing at the University of Mary Washington, has studied how consumers value hybrid and electric vehicles, including the financial and environmental motivations behind purchasing decisions. He was also named one of the 50 Best Undergraduate Business Professors of 2024 by Poets & Quants. View his profile Majid has also shared his expertise with WalletHub, offering first-pen perspective on car insurance costs, pricing fairness and the importance of making informed decisions when shopping for coverage. His insights are particularly relevant as Americans face record-high car payments, with insurance premiums adding another significant expense to the overall cost of vehicle ownership. As consumers grapple with rising costs, Majid can help explain what's driving vehicle affordability challenges, how purchasing decisions are changing and what motorists should consider before taking on substantial financial commitments.

Measles Makes a Dangerous Comeback as Pennsylvania Outbreak Tops 1,000 Cases

Measles was declared eliminated in the United States in 2000. More than 25 years later, the highly contagious disease is making a troubling comeback, with Pennsylvania now confronting an outbreak that has surpassed 1,000 confirmed cases. According to an October 7 update from the Pennsylvania Department of Health, the state has recorded 1,078 confirmed cases across 41 counties, including 207 hospitalizations and five measles-associated deaths. The figures underscore the serious public health consequences of a disease that can largely be prevented through vaccination. The outbreak is also raising important questions about declining vaccination rates, community immunity and whether other states could experience similar outbreaks. Measles spreads through the air when an infected person breathes, coughs or sneezes. The virus can remain infectious in the air for up to two hours after an infected person leaves an area. Early symptoms include fever, coughing, a runny nose and red, watery eyes, followed by a distinctive rash that typically begins on the face and spreads downward. While many people recover, measles can cause serious complications, including pneumonia, brain swelling and, in rare cases, death. Two doses of the measles, mumps and rubella (MMR) vaccine are approximately 97% effective at preventing the disease. Understanding the Outbreak and What Comes Next Dr. Lynn O. Lewis, a Professor of Biological Sciences at the University of Mary Washington, brings extensive expertise in microbiology, virology and infectious diseases. Lewis also directs the university's Irene Piscopo Rodgers School of Science and helped provide scientific guidance during the COVID-19 pandemic. View her profile With measles cases continuing to mount, Lewis can provide valuable perspective on how the virus spreads, why vaccination remains critical and what public health officials can do to contain outbreaks. She is available to help journalists explore several important questions: Why is a disease once eliminated in the United States returning? What makes measles so contagious? How do vaccination gaps contribute to outbreaks? And what lessons from the COVID-19 pandemic can help communities respond more effectively? As Pennsylvania continues its response, the outbreak is a reminder that infectious diseases once considered under control can re-emerge when the conditions that prevented their spread begin to change.

As Clocks Tick Toward the End of Daylight Saving Time, a UMW Sleep Researcher Explains What Your Body Actually Goes Through

The House passed the Sunshine Protection Act on July 14, 2026, reviving the national debate over whether the U.S. should adopt permanent daylight saving time, return to permanent standard time, or keep the twice-yearly clock change altogether. The bill now heads to the Senate. At the University of Mary Washington, Dr. Hilary Stebbins, Associate Professor of Psychological Science, studies the chronobiology and sleep patterns of college students, research that can help inform exactly this debate: how does shifting the clock affect cognitive performance and behavior, no matter which system we land on? Dr. Hilary Stebbins is an Associate Professor in the Department of Psychological Science at the University of Mary Washington. She is an expert on sleep deprivation, circadian rhythms, and dopamine function, and how each affects cognitive performance and behavior. View her profile Stebbins doesn't take a side in the policy debate. Her focus is chronobiology, how sleep patterns and circadian rhythms affect college students' cognitive performance and behavior. But that science speaks directly to the choice lawmakers are weighing: any shift, whether it's permanent daylight saving time, permanent standard time, or sticking with the current system, creates a temporary mismatch between our internal clock and the outside world, and it takes the body time to catch up. "One of my past teams found that as people report higher levels of sleepiness, they show higher dopamine function and also have more difficulty controlling impulsive actions." — Dr. Hilary Stebbins, Associate Professor of Psychological Science, University of Mary Washington Stebbins leads a year-long undergraduate research team (PSYC 491/492) each year, and in 2018 a team of her students won the Virginia Association for Psychological Science's award for best undergraduate paper for their research on sleep deprivation.
