The combination of extreme heat, active wildfires, heavy rainfall, and damaging winds created a weekend of sharply contrasting weather conditions. According to CBS News, forecasters expect the dangerous heat to gradually shift east during the week, bringing unusually high temperatures to additional states.
The most intense heat was recorded across the Great Basin, the Rockies, and parts of the desert Southwest. In Billings, Montana, temperatures climbed to a record 110 degrees, while Salt Lake City reached 109 degrees, matching a new all-time high. According to the National Weather Service, much of Utah remained under an extreme heat warning scheduled to continue through Tuesday morning.
Record Temperatures Spread across the West as Wildfire Concerns Grow
The heat dome developed after the first major heat wave of the summer settled over the western United States last week. According to CBS News meteorologist Nikki Nolan, temperatures in several areas were forecast to remain 20 to 30 degrees above average for this time of year, with additional record highs expected during the week.
The National Weather Service warned that widespread daytime temperatures between 105 and 115 degrees could increase the risk of heat-related illnesses, including heat stroke. The agency also said that unusually warm overnight temperatures would provide limited relief, increasing heat stress over several consecutive days.
The prolonged heat also heightened wildfire concerns. Near Los Angeles, the Summit Fire burned nearly 3,000 acres in the Antelope Valley and temporarily forced evacuations. According to the Los Angeles County Fire Department, the fire reached 31% containment by Sunday evening after firefighters made significant progress.
In Colorado, firefighters continued battling the Aspen Acres Fire while two additional wildfires ignited in the state’s high country. Democratic Senator John Hickenlooper toured the affected areas and called for increased funding to support wildfire response, saying there had been significant cuts affecting fire services and the Bureau of Land Management.
Severe Storms Bring Flooding and Damaging Winds to Eastern States
While western states dealt with dangerous heat, communities farther east faced heavy rainfall and severe thunderstorms. In New Orleans, several inches of rain fell during storms, forcing some residents to move through knee-deep floodwaters as streets became inundated.
Philadelphia was recovering from powerful microbursts that produced wind gusts of up to 70 miles per hour. The storms damaged homes, toppled trees, and brought down power lines across several neighborhoods. According to CBS Philadelphia, Mayor Cherelle Parker signed a Declaration of Disaster Emergency on Sunday following the widespread damage.
Missouri also experienced significant flooding during the weekend. According to CBS News, rescue crews airlifted more than 200 people from a children’s camp after between 6 and 12 inches of rain fell across the southeastern part of the state.
Meteorologists said the same weather system responsible for the damaging winds in Pennsylvania was expected to continue producing severe weather across parts of Georgia and South Carolina. At the same time, the expansive heat dome was forecast to move farther east, with excessive heat expected to reach portions of the Great Lakes and eventually approach the Northeast during the middle of the week.
