Heat dome to push extreme temperatures across much of US this week
The Kansas City, Missouri, area, which hasn't seen 100 degrees in two years, could reach the figure multiple times this week, AccuWeather Senior Meteorologist Chad Merrill said. Dallas could see 100 degrees for the first time in 2025.
Almost 85 million Americans from South Dakota to Texas and North Carolina to Florida were already under National Weather Service extreme heat warnings, watches or advisories July 21. The heat will intensify July 22 and deep into the week − and possibly beyond.
"By midweek, 90s will have spread from the South into the Midwest and Great Lakes," wrote Jonathan Erdman, a senior meteorologist at weather.com.
Parts of Texas, Arkansas and Louisiana will have highs peak at near or above 100 degrees, and a much larger area of the South, Midwest and Great Lakes will see a heat index surpassing 100 degrees, he said.
"This has the look of a long-lasting heat wave with limited rainfall," Merrill said. "Drought will expand through the central Plains by mid-August and worsen in Kansas and Nebraska, where there are already pockets of moderate to extreme drought."
Angry storms, 'heat dome': Threaten to fuel dangerous weather week
Brief respite for Northeast before heat dome advances
The Northeast will enjoy a few days of lower humidity and cooler temperatures before a "bubble" from the heat dome slips away from the Midwest and brings brutal heat east, AccuWeather forecasts. Temperatures will dip into the 60s in New York and Washington, D.C., the 50s in Boston and into the 40s in some areas of the Northeast's interior.
The respite will wrap up by Friday, when the high temperature for Washington is forecast to reach almost 100 degrees. Detroit will reach deep into the 90s Thursday and Friday. Philadelphia will push close to 100 Friday and Saturday.
"The late-week scorcher heading into the East will be a quick whiplash," AccuWeather Senior Meteorologist Chad Merrill said.

NYC air quality worsens again amid Canadian wildfire haze
NEW YORK — Hazy skies and low air quality returned to the five boroughs on Monday, as smoke from Canadian wildfires again created a gray scene in the New York skies. All of New York state and almost all of New England was under an air quality alert from the National Weather Service on Monday afternoon. The warning for New York City extended until midnight. 'Air quality is unhealthy for sensitive groups, including older adults, children, and people with heart or lung conditions,' NYC's emergency department wrote on social media. 'You may notice a faint smell of smoke, and low visibility conditions.' It has become a depressingly familiar story for New Yorkers in recent years. Smoke from uncontrolled wildfires in Canada, most of them in the province of Manitoba, has been carried south and east by common wind patterns. The worst air quality in recent years occurred in June 2023, when the smoke became so thick it created an orange haze over the city. However, the subpar air quality has returned to the city in each of the past two summers as well, including multiple times earlier this year. 'Limit outdoor activity, close windows, use air purifiers if available, and consider wearing a high-quality mask if you must go outside and are in a sensitive group,' NYC Emergency Management warned. New York was hardly alone in dealing with poor air quality on Monday. All of Maine, New Hampshire, Massachusetts, Rhode Island, Connecticut and Delaware, along with the majority of Vermont were also under air quality alerts. _____

Heat wave coming to Southern California: Here's when temperatures will spike
The Brief Southern California is preparing for its hottest weather of the summer, with temperatures expected to rise significantly starting on Wednesday. The heat is caused by a high-pressure system, which will push inland temperatures 5 to 10 degrees above normal and create a heightened fire risk. The peak of the heat wave is forecast for Thursday, with a cooldown expected to begin by Saturday. LOS ANGELES - Southern California this week is bracing for what appears to be the hottest weather so far this summer. According to the National Weather Service, warmer-than-normal temperatures will begin on Wednesday and peak on Thursday across Southern California. Temperatures will rise sharply, as much as 10 degrees above normal, especially inland. "This warming will push many interior areas to 4 to 6 degrees over normal, with 90s in the valleys and 100-103 degree readings in the western San Fernando Valley," the agency said. The agency warns that potentially hazardous heat is possible on Friday, Aug. 8 through Sunday, Aug. 10. "Most areas will end up 5 to 10 degrees above normal. Two exceptions will be the San Gabriel Valley, San Fernando Valley, and Calabasas area where max temps will be 10 to 12 degrees above normal." Max temps in the valleys will range from 95 to 106 degrees, with the deserts sizzling with max temps from 105 to 107 degrees. The hot temperatures are the result of a high-pressure system expanding over the region. Accompanying the heat will be widespread strong winds, elevating fire weather danger. The NWS has issued an elevated fire weather warning for Santa Barbara County from Wednesday, Aug. 6 to Saturday, Aug. 9 due to this increased heat. Officials said heat advisories are likely for most of the Los Angeles area but will be issued towards the end of the week when temperatures will be hottest. A cooldown is expected by Saturday, Aug. 9. According to the NWS, the only triple-digit heat will be found in the Antelope Valley, with the warmest valley locations reaching the mid-90s.
