Maps show Southeast heat advisories, air quality alerts in Midwest
The Southeast will see temperatures in the high 80s and 90s on Thursday, with "feels-like temperatures" over 100 degrees in multiple places. Those temperatures are about 10 to 15 degrees higher than average temperatures recorded around this time of year.
Over 58 million people in the region, including parts of Texas, Alabama and Florida, are under heat advisories through Thursday night. Residents of Arkansas, Tennessee and Louisiana are under extreme heat warnings. Heat warnings mean people should prepare for "extremely dangerous heat conditions," according to the National Weather Service, while heat advisories are less severe.
Heat-related illnesses can increase significantly during times of extreme heat and high humidity. It's recommended to stay out of the sun and in an air-conditioned room if possible. People should drink plenty of fluids and check on relatives and neighbors.
A cold front has brought temperatures in the high 70s and low 80s to the Northeast and Midwest after multiple days of extreme heat. New York City broke a record earlier in the week: LaGuardia Airport recorded temperatures of 100 degrees Fahrenheit on Tuesday afternoon.
The Northeast and Mid-Atlantic regions are expected to see heavy rain and stormy conditions on Thursday. Some cities may see 3 to 5 inches of rain through Friday, with some areas seeing as much as 7 inches of rainfall. The storms may also bring damaging winds and large hail.
In some regions, rainfall rates may exceed 2 inches per hour, raising the risk of flooding. Over 47 million people are under flood watches through Friday. The highest threat level is for the area between New York City and Washington, D.C.
That same cold front is expected to pass through the Southeast, bringing more heavy rain and lowering temperatures over the weekend. Parts of the Southeast may see between 2.5 and 4 inches of rain in the coming days.
Parts of the U.S. are also continuing to see poor air quality from Canadian wildfire smoke. Much of Minnesota, Michigan and Wisconsin are seeing "unhealthy" air quality levels, which means that the general public may experience health effects, according to AirNow. Parts of Illinois, Iowa and North Dakota are also seeing "unhealthy" levels.
In other surrounding states, the air quality level is unhealthy for sensitive groups.
CBS Chicago reported hazy skies and visibility of just two miles as the smoke envelops the city. The smoke is expected to linger through Thursday and into Friday.

Crews struggle to contain massive California wildfire that's injured 3 people
SANTA MARIA, Calif. (AP) — A massive wildfire is churning through Los Padres National Forest in central California, threatening hundreds of homes and injuring at least three people, authorities said. The Gifford Fire spans more than 100 square miles (259 square km) of Santa Barbara and San Luis Obispo counties, with just 3 percent containment, according to a Monday incident update. The blaze grew out of several smaller fires that erupted Friday along State Route 166 between Santa Maria and Bakersfield. More than 450 structures are under threat. One resident was hospitalized with burn injuries and two contract employees assisting firefighters were hurt when their all-terrain vehicle overturned, authorities said. More than 1,000 firefighters working in hot and dry conditions are scrambling to make progress against the flames before so-called sundowner winds whip up around dusk. The National Weather Service says erratic afternoon gusts could reach 25 mph (40 kph) in the fire area.

Flood-hit Beijing prepares for new round of heavy rain as rescuers retrieve bodies
More rain is predicted for Beijing, already recovering from floods. 44 people died in July floods. Up to 200mm of rain could hit parts of Beijing, warned weather forecasters. Beijing on Monday warned residents in its mountainous suburbs to brace for another round of heavy rainfall, a week after catastrophic floods killed dozens in the deadliest deluge to hit the Chinese capital since 2012. Up to 200mm of rain could hit parts of Beijing over a six-hour period from 12:00, weather forecasters warned. The city of 22 million people receives on average 600mm of rainfall each year. The alert comes as authorities rush to reinforce ageing flood defences, fine-tune weather forecasts and update evacuation plans amid reports of bodies being pulled from raging flood waters across the country, including at least three at a flooded wellness camp in Hebei province. Late in July, at least 44 people died in Beijing after days of heavy rains. Most of the dead were people unexpectedly trapped by rapidly rising waters at a nursing home in Miyun district on the city's northeastern outskirts. Feature China/Future Publishing via Getty Images The fatalities led authorities to admit to shortcomings in their contingency plans for extreme weather. On Monday, Beijing had seven of its 16 districts on the highest level of preparedness for flood prevention - Mentougou, Fangshan, Fengtai, Shijingshan, Huairou, Miyun and Yanqing - most of which lie in mountainous areas to the west and north of the city. The risk of flash floods and landslides is 'extremely high', authorities said. In the summer of 2012, 79 people died in Beijing in the city's deadliest flooding in living memory. Fangshan district was the worst-hit, with one resident reporting a rise in floodwaters of 1.3m in just 10 minutes. Beijing's topography has been described by some as a rain 'trap', with its mountains to the west and north capturing moist air and amplifying any ensuing rainfall as a result. As of Saturday, torrential rains that swept through 'Beijing Valley', a riverside wellness retreat in the Hebei city of Chengde adjacent to Beijing, had claimed three lives, with four still missing, China's state news agency Xinhua reported. Around 40 people had gathered on 27 July for an event at the site, where organisers directed them into tents pitched on low-lying land next to a river bend, Caixin Media reported. By 02:00, floodwaters had risen to knee height, forcing attendees to scramble toward the camp's only exit. The site bore similarities to Camp Mystic in Texas, where at least 28 children were swept to their deaths in July by floodwaters after the Guadalupe River burst its banks amid torrential rain. In China's southern Guangdong province over the weekend, the bodies of five people were recovered after a large-scale search operation involving more than 1 300 rescuers. The five people, who went missing on Friday night, were 'swept away by water' following heavy rainfall in recent days, Xinhua reported on Sunday.

Hudson Valley weather: Warm, sunny and hazy Aug. 4 in Westchester, Rockland, Putnam
The Lower Hudson Valley can expect some warm and sunny weather for the first full week of August, but residents will want to be ready for air quality issues due to Canadian wildfires. The National Weather Service issued an air quality alert for Westchester, Rockland and Putnam counties Monday, Aug. 4, valid until midnight Aug. 5, thanks to raging wildfires up north in Canada. Lower Hudson Valley air quality alert Monday, Aug. 4 NYSDEC said ground level ozone and particulate matter in the air due to wildfires in Ontario could exceed safe air quality index levels over 100. As of 9:45 a.m., measured the Lower Hudson Valley's Air Quality Index as "Moderate," with an AQI score of 74, an Ozone level of 14 and a particulate matter level of 101. NYSDEC says the risk for individuals who may be prone to respiratory illness was expected to increase as the day continues, and temperatures rise. At-risk populations for poor air quality include "the very young, and those with preexisting respiratory problems such as asthma or heart disease," said NWS in the alert. NYSDEC said those at risk should stay inside and limit physical activity. Sunny skies and warm temperatures to kick off August Despite air quality issues, Monday is presenting itself to be a beautiful day. There will be some widespread haze due to the smoke from the Canadian wildfires, but skies will be sunny with high temperatures near 89 degrees. Overnight, the haze is expected to stick around with partly cloudy skies and lows near 66 degrees. Tuesday and Wednesday should look similar to Monday.
