What to expect for July 4 weather: Storms and heat
Why it matters: Scorching hot temperatures and widespread thunderstorms may disrupt your festivities or cause travel delays for the record-number of people hitting the road this holiday weekend.
Here's on the menu for July 4 weather.
What to expect for July 4th weather
Zoom out: Much of the United States will see clear skies for fireworks. But it might be hot. Like, really hot.
Parts of the Upper Plains will see temperatures surge 10 to 20 degrees above average on Thursday and Friday, according to NOAA's weather outlook for the weekend. A cold front will push that hot air to the Great Lakes and Appalachians over the weekend.
Parts of Minnesota are under a heat advisory, with the heat index near 100 degrees.
The Southeast will also see higher temperatures, according to NOAA, and triple digit temperatures are expected in parts of Texas.
What they're saying: Bryan Jackson, a meteorologist at the NWS Weather Prediction Center, told Axios that those in Wisconsin, Minnesota and the upper Midwest should stay weather aware due to the heat.
The other side: The Western U.S. will face below average temperatures caused by breezes off the Pacific Ocean, according to NOAA.
"It's still 104 in Phoenix, but that's below normal," Jackson said.
Areas of the Northeast — including Philadelphia, Boston and New York City — as well as North Dakota are under threat from storms to end the week, too. But "sunny, summer conditions" and "pretty great weather" are on tap for the Northeast this weekend, Jackson said.
Travel delays for July 4 are possible
Context: AAA projects 72.2 million Americans will travel domestically for the July 4 holiday period (defined as June 28 through July 6).
TSA expects over 18.5 million travelers to be screened from July 1 to July 7.
"This year, we're seeing strong demand for road trips, flights, and cruises, especially with the holiday falling on a Friday," Debbie Haas, vice president of AAA Travel, said in a statement. "This is allowing travelers to extend their getaways and make lasting memories with loved ones."
Yes, but: Rain could cause travel delays.
Sections of the Southwestern U.S. — Texas, New Mexico and Arizona — will face downpours Thursday and Friday, according to NOAA's weather outlook.
A frontal system could develop into a tropical storm off the coast of Florida, according to NOAA's National Hurricane Center.
Flashback: Showers and thunderstorms boomed in Florida, Baltimore and Washington, D.C., earlier this week. Congress was even worried about travel headaches ahead of the vote on President Trump's "big, beautiful bill."
Thunderstorms caused ground stops in New York City, and Washington, D.C., on Tuesday.
July 4 fire warnings
What to know: Parts of Oregon, Idaho, Nevada and Utah are facing red flag warnings, according to the National Weather Service's weather outlook.

The Best Way to Pack Your Carry-On Bag for Fourth of July Weekend Travel
Summer is in full swing, delivering scorching temperatures and vacation season for millions of Americans. If you've got a trip planned for the Fourth of July weekend, it's best to prepare early to ensure that you can relax while traveling, instead of stressing about every detail. Part of that preparation includes finding the carry-on that suits your needs and knowing how to pack it properly. A carry-on bag ensures you have your entertainment and snacks during the flight and all the essentials at your destination, even if your checked luggage gets lost. Items like passports, prescriptions, electronics, toiletries, cash and clothes are must-haves when it comes to carry-ons. (Believe me, packing extra clothes in mine saved me when my checked bag was lost on the way to London.) Following Transportation Security Administration guidelines for each major US airline is also a must. Doing a little research on the latest rules and regulations can help you ace the experience without getting held up. You can't control what TSA officials confiscate, but you can control what you pack and how you pack it. Here's how to pack your carry-on bag efficiently for any flight, so you can breeze through TSA security lines. For more travel tips, explore these travel essentials you need for every vacation and then take a look at this travel checklist. You should also read about the new Real ID requirement to get through airport security. The best carry-on travel bags Before you start packing, you'll have to find the right carry-on bag. Here are a few important things to keep in mind. What size carry-on should you get? The first and most important aspect to think about is size. Federal Aviation Administration regulations say carry-on items can't exceed dimensions of 22 by 14 by 9 inches, though you might find an inch or two of difference depending on the airline. The general rule is that it must fit under your seat or in the overhead enclosed storage compartment on the plane. Here's a quick reference for size limits for the most popular US airlines. Carry-on items by airline Airline Cabin Maximum size Air Canada All 55 x 40 x 23 cm; 21.5 x 15.5 x 9 in Alaska Airlines All 55.88 x 35.56 x 22.86 cm; 22 x 14 x 9 in American Airlines All 56 x 36 x 23 cm; 22 x 14 x 9 in British Airways All 56 x 45 x 25 cm; 22 x 18 x 10 in Delta Air Lines All 56 x 35 x 23 cm; 22 x 14 x 9 in Frontier Airlines All 60.96 x 40.64 x 25.4 cm; 24 x 16 x 10 in Hawaiian Airlines All 55.9 x 35.5 x 22.9 cm; 22 x 14 x 9 in JetBlue Airways All 55.88 x 35.56 x 22.86 cm; 22 x 14 x 9 in Southwest Airlines All 60.9 x 40.6 x 25.4 cm; 24 x 16 x 10 in Spirit Airlines All 56 x 46 x 25 cm; 22 x 18 x 10 in United Airlines All 56 x 35 x 22 cm; 22 x 14 x 9 in Carry-ons should have an easy access tech compartment If you decide to bring electronics like a laptop, iPad, Kindle or other tablet on board, your carry-on should ideally have a separate, padded compartment for secure packing. Be sure these compartments are easily accessible, since at security checkpoints, the TSA will require you to remove your electronic devices and place them in the plastic X-ray tray. Make sure your carry-on is comfortable on your back or shoulder Remember, you'll need to lug your carry-on bag or suitcase across the airport and down long corridors, and you might even need to run with it so you don't miss your connection. Consider whether you need padded handles or cushioned straps or a backpack or a rolling suitcase for ease. The general rule is that all carry-ons must fit under your seat or in the overhead enclosed storage compartment on the plane. Getty Images How to pack your carry-on the right way Though what to pack in your carry-on ultimately depends on your preferences, there are a few guidelines for the best way to pack your luggage: Pack items in layers (shoes one layer, clothes one layer, electronics one layer, etc.). Pack the things you'll use the least at the bottom of the bag. Keep most of your valuables in your carry-on luggage, and store them in side compartments or safely padded around other items. Place valuables at the bottom of your bag, away from the opening. Keep your wallet, credit cards and cash in an inner pocket so they'll be harder to steal. Pack a small, separate bag for toiletries. (Liquids, gels and aerosols packed in carry-on must follow the 3-1-1 liquids rule: 3.4 ounces or less per container; all liquids must fit in one quart size, clear, plastic, zip-top bag; one bag per passenger.) Roll your clothes tightly to save space in your luggage. Sometimes you lose your luggage. It happens. Though it's frustrating, it's important to pack a spare set of clothes (including socks and underwear!) in your carry-on to hold you over until your bags are found and returned. Pack clothing that can easily be rolled up and put in the bottom of your bag. Rolled clothing can save space in your tight bag or suitcase. Getty Images Essential items for your carry-on bag There's some items that are just better in your carry-on luggage. If you do decide to check a bag, be sure to keep these items with you on the flight. Most of these carry-on essentials are items that would be hard to replace or purchase when you get to your destination. Prescriptions and medications Contact lenses or glasses Valuables like jewelry, wallets, passports, IDs and boarding passes Cameras and smartphones Entertainment like tablets, books and laptops Headphones to watch TV or movies if a longer flight Chargers for electronics Printed itinerary, or hotel and flight confirmations Explore this complete guide for essential travel items you may forget to pack. Place your larger electronics in secure yet easily accessible compartments, since you'll need to pull them out at TSA security checkpoints. Getty Images What you should never pack in your carry-on bag The TSA has specific guidelines covering which items are banned from flights, and the agency takes those rules very seriously. In 2023 alone, the TSA screened more than 858 million passengers and crew members nationwide, and it confiscated a record number of firearms (6,737) and many other items. TSA policy says that individuals carrying weapons, especially loaded firearms, can face fines or criminal penalties. These are some of the most commonly confiscated items: Firearms Fireworks Box cutters, utility knives and razors Bats, clubs and blades Swiss Army knives If in doubt, always refer to the TSA's guidelines on packing for flights, to ensure you have safe and easy travels. If you're planning a vacation soon and are stressed about packing or preparing, CNET has plenty of resources to help. Get ready for your next trip with these hacks and tips:

Millions don't use AC. Why Americans are turning off air conditioners this summer
About 39 million Americans don't use AC. While many can't afford it or don't need it (yet, as the planet warms), some simply don't like it. As the thermometer inside Shelley Snyder's three-story Victorian home in Columbus, Ohio, hits 88 degrees, she is finishing a meeting with a new maid service, watering plants, and doing chores. And she's doing it all without air conditioning. Snyder said she is just fine without it. Even during heat advisories, she's found ways to cope. 'We wait all winter so we can open the windows and doors and let fresh air and summer in,' she told a reporter on a day the heat index exceeded 100 degrees. Snyder is one of about 39 million Americans − roughly 12% − who don't use AC, according to the U.S. Energy Information Administration. While many can't afford it or don't need it because they live in cooler climates, others choose to forgo air conditioning to lower their carbon footprint. Then there are those like Snyder, who chooses to endure sweltering temperatures in her "big old house with high ceilings" and top-floor skylight windows that open. "Ceiling fans just pull the cool air out of the basement right up through the house," she said. Though air conditioning can be life saving − particularly amid record setting heat waves like the one that scorched the country in late June − some people simply don't like it, according to Gail Brager, director of the Center for the Built Environment at the University of California, Berkeley. Constant AC use can cause "experiential monotony," Brager said. 'There's nothing pleasurable about it," she said. "It's not healthy for our bodies to have the same conditions all the time, everywhere, and it's also experientially, not very interesting or necessarily comfortable.' Cooler cities and states don't need AC - yet Alaska leads the nation in going without AC, according to an analysis of U.S. Department of Energy data by University of California, Berkeley professor Lucas Davis. Just 7% of households there are air-conditioned, yet the state's temperatures are rising exponentially as the planet warms. Officials issued historic advisories during June's heat wave in Alaska, where it's warming two- to three-times faster than the global average. In the lower 48 states, the least air-conditioned city is San Francisco, where nearly 55% of homes don't have AC, according to data from the U.S. Census Bureau's American Housing Survey. Devin Carraway's home is one of them. Carraway said he's lived in the Bay Area for most of his life and heat waves are rare, thus eliminating the need for air conditioning. Even if the climate were to change, he said "AC is not going to be the first thing I do." "AC is throwing a lot of energy at a problem that needs to be solved through building design first," Carraway said. Instead, Carraway has opted to install insulation and a white roof, which absorbs less heat. He said solar panels on the roof and his neighbor's "really wonderful Monterey cypress tree," also help keep his home cool on the occasional hot days. AC out of reach, assistance under threat Many Americans simply can't afford AC due to the rising costs of summer cooling. That could put them at higher risk of heat illness and death. This summer, the average electric bill is projected to reach $784, the highest cost in at least 12 years, according to the National Energy Assistance Directors Association. Black, Hispanic and lower income households are more likely to say they don't have or don't use air conditioners due to financial challenges, according to health policy organization KFF. "Many are afraid to turn on the air conditioning because of the cost," said Mark Wolfe, executive director of NEADA. There are state and federal programs that help customers on with limited income pay their energy bills, but Wolfe said they aren't enough to meet the growing need. And the Trump administration's proposed 2026 budget would eliminate funding for one of those programs, the Low-Income Home Energy Assistance Program (LIHEAP). If enacted, Wolfe said nearly 6 million households may have to go without air conditioning or heat. Tuesday Adams, 56, of Cathedral City, California, may be one of them. She arrived at a county aid office June 25 clutching overdue utility bills topping $20,000 as temperatures hit 102 degrees. Southern California Edison has extended her deadline for more than a year, but she's received a disconnection notice. She said she has received LIHEAP help in the past, but tries not to ask too often. Informed about the looming elimination of all federal funds for the program, she didn't mince words. "They got to do something, they can not stop this program ... there's too many people out here really, really struggling ... a lot of families are gonna be in the dark in this heat," she said. Giving up AC to break the 'vicious cycle' of climate change Residential energy use, which includes cooling, heating and powering homes, accounts for roughly 20% of greenhouse gas emissions in the United States, according to a 2020 study published in the Proceedings of the National Academy of Sciences of the United States of America, a peer-reviewed scientific journal. 'It's this really vicious cycle that air conditioning is contributing to greenhouse gas emissions and global warming, and then the warming temperatures are making us need air conditioning even more,' Brager said. Stan Cox wants to break that cycle. The author of 'Losing Our Cool: Uncomfortable Truths About Our Air-Conditioned World,' deploys fans or spends time in the basement on hot days at his home in Kansas, which is shaded by trees. As a result, he used 80% less electricity than his neighbors in similarly-sized homes last June, he said citing his utility bill. He admits something of a "love-hate relationship" with the innovation. When he experienced central air as a kid in 1967, he thought he had "died and gone to heaven," but he later came to dislike the contrast between indoor cold and outdoor heat. 'I just didn't like it," he said. But Cox does turn on the AC at least once each summer "just to make sure it's still in good working order." "Or if we have people coming to dinner," he said. "Because we can't really invite people to dinner when it's 85 degrees in the house." Back in Columbus, Ohio, Snyder's neighbor has a large oak that partially shades her home in the morning. And when it does get toasty or stuffy inside, Snyder said she finds chores to do in her basement or outside. Snyder has a portable window AC unit, but she reserves it only for visitors who stay the night. She hasn't used it in 10 years. "I appreciate air conditioning like the next guy," she said. "Would I personally like to have it? Sure. I'll be 70 this year. But I've gone this long without it." Contributing: Sara Chernikoff and Sarah Elbeshbishi, USA TODAY

What's open and closed on July Fourth
The Fourth of July holiday, also known as Independence Day, celebrates the Second Continental Congress' unanimous adoption of the Declaration of Independence on July 4, 1776. A year later, according to the Library of Congress, a spontaneous celebration in Philadelphia marked the anniversary of American independence. But observations weren't commonplace until after the War of 1812, when they quickly took off. Congress was late to the party, finally passing a law making Independence Day a federal holiday on June 28, 1870. Here's what is open and closed this year on the Fourth of July: Government offices, post offices, courts and schools are closed. U.S. stock markets and banks are closed Friday. Most FedEx and UPS pickup and delivery services will also not be available. Warehouse membership club Costco is closed on July Fourth. Most other major national retailers such as Target and Walmart will be open, with some offering promotional sales to lure customers. Most grocery stores are also open. Hours may vary by location, so check your local store. Millions of Americans are expected to hit the road, taking advantage of the Fourth of July falling on a Friday this year. Spokeswoman Adrienne Woodland said AAA is forecasting that a record 72.2 million Americans will travel domestically between June 28 and July 6, an increase of 1.7 million over last year and 7 million more than in 2019. AAA estimates 61.6 million Americans will drive and 5.8 million travelers will fly. Woodland recommended that anyone traveling over the holiday should consider taking precautions, including a pre-trip inspection of their vehicle to avoid issues such as dead batteries, flat tires and empty gas tanks. ___
