Is the heat wave over yet? Do these things until the heat breaks.
A major heat wave will persist through the end of the week in some areas of the country. Here's what to do while the temperatures remain high.
Forecasters predict the worst of a record-setting heat wave may soon be over — but millions still need to take precautions to stay safe from dangerous heat.
The most significant heat conditions are expected to continue across the Mid-Atlantic through Thursday, June 26 and the eastern Ohio Valley into Friday, June 27, according to the National Weather Service.
AccuWeather meteorologists said extreme heat may begin to subside Wednesday, June 25, in New England, the Upper Midwest and the Plains, with temperatures dropping into the 70s and 80s.
For those still experiencing the oppressive heat, here's some tips for how to find your own bit of relief.
Save energy but keep your home cool
The balance between staying cool and keeping energy costs low can be tricky amid a heat wave, when sitting in front of a blasting air conditioner is oh-so-appealing.
The Environmental Protection Agency's energy-efficiency program Energy Star recommends setting the thermostat to 78 degrees when you wake up during summer months to maximize efficiency.
Michael Webber, a professor of engineering who studies energy at University of Texas at Austin, said pre-cooling your home by running the air conditioning more in the morning and evening, and less in the afternoon when temperatures are at their peak can go a long way, too.
'Picking the right temperature and cooling your house at the best times, these are things you can do for free essentially,' to stay comfortable and save on energy costs, Webber said.
Portable electric fans can also help make a room feel cooler, but the National Weather Service recommends pointing them away from yourself when the room temperature is higher than 90 degrees. The dry blowing air can lead to dehydration, the agency says.
If you don't have air conditioning, or if it isn't working, libraries, shopping malls, grocery stores and public cooling centers can also offer relief from scorching temperatures.
Pay attention to your hydration
You might want to think twice before ordering that large iced coffee – or margarita pitcher.
Hydration is the name of the game during a heat wave and Betsy Koickel, chief medical officer at GoHealth Urgent Care, said 'excessive alcohol or caffeine intake can increase the risk of dehydration.'
The American Red Cross said the average person should drink about three-fourths a gallon of water a day.
Koickel recommended drinking water before you feel thirsty and replenishing with electrolyte replacements, such as Gatorade, especially if you plan to exercise or sit outside for extended periods.
Consistent water intake may be particularly important for people taking medications that can cause dehydration, including some blood pressure drugs, antidepressants and antibiotics.
She also said easy-to-digest foods, like fruits and salads, can help with hydration.
If you need to wander outside, you can protect your skin by frequently reapplying sunscreen, wearing a loose, brimmed hat and choosing light-colored clothing.
Be careful about what you wear
The EPA recommends avoiding direct exposure to the sun between 10 a.m. and 4 p.m., when the sun's rays are the strongest and taking frequent breaks in the shade to cool off.
Remember the symptoms of heat exhaustion
In extreme cases, intense heat can lead to sickness as your body struggles to regulate its temperature.
Early symptoms of heat injury, including thirst, lightheadedness or a headache, may develop if you don't properly hydrate, Koickel said. Dark-colored or foul-smelling urine may be another sign of severe dehydration.
'If you don't take steps to rehydrate at that point, it can lead to heat exhaustion. You could faint. You could start to experience some severe muscle cramps, excessive sweating, and then if that's not taken care of, it can eventually lead to heat stroke.'
Heat stroke can occur when someone's body temperature reaches 100.4 degrees. If heat illness reaches that point, she recommended calling 911 or finding immediate medical attention.

What Is a Heat Dome? The Scary Weather Phenomenon Returns to Kick Off Summer
It's a hot one out east where I live, and has been for a few days. As much as the heat here in upstate New York has me cooped up inside with the air conditioner blasting, it's nothing compared to other parts of the US now impacted by one of the summer's freakiest weather patterns: the heat dome. If that's a new phrase to you, keep reading and I'll break down what a heat dome is and what causes it, and for more help, read CNET's list of hacks for keeping your home cool in the summer. What is a heat dome? Think of a heat dome as similar to putting a lid on a pot or a frying pan while cooking something, Alex Lamers of the National Weather Service told NPR. A heat dome is what happens when a high-pressure system lingers, causing hot air to become trapped under it, resulting in prolonged temperature spikes. Just like how putting a lid on a pot or pan traps the heat and cooks the food faster. Except in this case, the food is you and me. This is made worse by the fact that high pressure systems are known to cause dry weather, which can also contribute to hotter temperatures. According to the heat map provided on the National Integrated Heat Health Information System's official website, heat risks are elevated for most of the country between the Midwest and Lower Mississippi Valley regions and the East Coast, with eastern North Carolina, central Virginia, the Pittsburgh area, southeast Pennsylvania, southeast Maryland, most of New Jersey and almost all of Delaware being under extreme heat warnings. In the hardest-hit areas, temperatures may go as high as 115 degrees, while others will hover between 95 and 100 degrees. All around, it's the kind of weather than can make the prospect of a power outage a life-or-death scenario. How long does a heat dome last? I wish I had better news for you. Unfortunately, heat domes are known to last anywhere from a few days to a few weeks, all dependent on how long it takes for the high pressure system in a given region to move on or dissipate. While AccuWeather reported on June 24, that incoming rainstorms will provide some areas with relief, not every region will be so lucky. Some areas will see the heat dome break down more gradually. So, if you were maybe hoping to tough things out without putting the AC in, probably time to reconsider. Does climate change make heat domes worse? Oh, absolutely. Speaking to Time Magazine for a report on the current heat wave, Bill Gallus, a professor of meteorology at Iowa State University, said that cause-and-effect question was "one of the easier (questions) to answer." Heat domes, he explained, are one of the more likely consequences of worsening climate change, even more so than other related weather events, such as increased tornadoes and stronger hurricanes. "There's so many things that are complicated and we can't say for sure what climate change is going to do, such as how many hurricanes or tornadoes we get," Gallus said. "But it is likely that we will have more heat domes, and probably hotter temperatures in the heat domes." How can I avoid a heat dome? As you might be able to tell from all these explanations so far, there's not much to do about a heat dome except to get away from it. This might entail staying inside where it's cool, or going away to some other place that isn't suffering under a high-pressure system. Maybe head out to the west coast, where my other CNET colleagues -- whom I am not jealous of and never have been, promise -- insist the weather is positively temperate. Hope you're all having fun out there, guys. Or hey, maybe try the old summertime standby and go see a movie in a nice air-conditioned theater. That new F1 movie looks pretty neat.

Extreme heat expected to continue during the week, weather experts warn
As millions of Americans return to work June 23 for the first full week of summer, they will face scorching temperatures that could reach as high as 100 degrees, particularly in the Mid-Atlantic region, weather experts said. 'The toughest days are going to be Monday through Wednesday to get through,'' said Brian Hurley, a meteorologist with the Weather Prediction Center, part of the National Weather Service. A heat wave is expected to continue across the Midwest, Mid-Atlantic and the Northeast putting more than 150 million Americans under heat advisories, heat warnings or extreme heat watches, according to the National Weather Service. A heat warning is more extreme with temperature possibly reaching as high as 110 degrees, but all the conditions can be dangerous, said Hurley. 'It's a concerning issue just because of the fact that we're not really getting much relief, if any, at night," he said. 'We're not cooling off so it's going to feel pretty extreme.'' Some temperatures could reach 15 degrees above normal for June. It's early to see triple-digit temperatures, which usually happen in July, Hurley said. The Mid-Atlantic corridor, including Washington, D.C., Philadelphia and New York, is likely to be hardest hit. In the Washington, D.C., metro area temperatures are expected to reach 100 degrees early in the week with night-time temperatures in the 80s. "Those overnight temperatures are going to struggle to get below 80 degrees,'' he said. Hurley noted that D.C. just recently hit it's first 90-degree day. D.C. Mayor Muriel Bowser issued a heat alert for Sunday, June 22, and extreme heat alerts for Monday through Wednesday, June 23-25. Officials urged residents to check on seniors and access cooling centers across the city. Cooling buses were also deployed for people without shelter. Other areas also expected to be impacted by the extreme heat include Raleigh, North Carolina and Richmond, Virginia. Both are predicted to experience near-record or record daily temperatures of more than 100 degrees early in the week. 'It's really the brute force of it all,'' he said noting the temperature shift. 'That's why it's going to feel a bit stifling.''Either way it's going to feel miserable,' he said. The extreme conditions could be dangerous. Experts recommend people limit outdoor activities, stay hydrated, put on air conditioning early in your car, bring water bottles and find access to cooling centers. The first day of summer, June 20, kicked off with a heat wave blanketing some parts of the country and continued into the weekend. Much of the Midwest, Mid-Atlantic and the Northeast was under heat advisory warnings, according to the National Weather expected to cool off – a little – by the end of next week with temperatures in the lower 90s. 'That will feel a lot nicer,'' Hurley said. This article originally appeared on USA TODAY: Millions expect to brace for early summer heat wave

As heat wave boils US, what is the right temperature to set AC? Cast your vote.
Experts say 78 degrees is ideal for energy efficiency, but we want to hear from you. What is the right summer AC temperature? Scroll down to take our poll. On the first official day of summer, as the outside temperature in Phoenix climbed to a moderate 104 degrees, my partner eyed me cautiously and broached the question he knew I was dreading. 'I think it's time to lower our AC.' I sighed. We can't, I protested. Our utility company was already sending us warning emails that our bill would 'exceed the threshold you had set' (blame the 111- and 113-degree days that preceded this). On Friday, June 20, summer had only officially begun – though we'd been in triple digit territory for the better part of two months – and we couldn't give in now, in this economy. Besides, our thermostat was already set to the temperature experts agree is best: 78 degrees. Which is the correct temperature. Is 78 too hot for a house? As the nation grapples with a major heat wave with temperatures soaring to extremes on the East Coast, Midwest and in the Plains – coupled with something I, mercifully, don't have to contend with: humidity – I wanted to know: Am I right? (Scroll down or click here to take our poll.) Turns out, most Arizonans agree with me. An Arizona Republic reader poll found that most people preferred 78, with 80, 77 and 76 degrees rounding out the top four. My very unofficial research in my group chats of former and current Phoenicians found the same thing – though I am immensely jealous of a friend in San Diego who 'hardly uses' it. This aligns with what the Environmental Protection Agency recommends to maximize efficiency and save money. But outside of Arizona, answers have varied wildly. Colleagues have bravely admitted they set it at 74 and even 73 degrees. When discussing this column, my editor confessed he used to keep his AC at an icy 68 degrees. The bill would be well past $200, he said. (I didn't have the heart to admit ours was well past that now.) While all of those sound like a nice reprieve from the outside temps – and some downright frigid – none of them seem 'right' to me. Was Trump wrong to bomb Iran? Are you concerned about war? Tell us. | Opinion Forum What is the best temperature to set your AC? Vote below. So I want to know what you do. What is the ideal temperature to set your AC to – for comfort or for energy efficiency? If you don't have AC, what methods do you use to stay cool amid record-setting heat waves like this one? Do you think we've reached the point where everyone should have AC, or can we survive without it? Cast your vote in our poll below – and stay cool out there.
