• Scorching Heat Sweeps Mid-Atlantic: As the region swelters under excessive heat alerts affecting over 100 million people over the course of the weekend, the impending heatwave is set to push from the Ohio Valley on Saturday to the Mid-Atlantic on Sunday.

Baltimore, too, reached 101 degrees Fahrenheit, breaking the daily record of 100 degrees set back in 1988. The weather service warns that the early arrival and prolonged duration of the heatwave can significantly increase heat stress for individuals without access to reliable air conditioning.
• Floods Demand Evacuations in Iowa: The small town of Rock Valley, Iowa, issued mandatory evacuations for homes located north of Highway 18 due to high floodwaters on Saturday.

The Upper Midwest is expected to receive up to 5 inches of rain through Sunday, following approximately 10 inches of rain over the previous 48 hours.

Starting Monday, Ruidoso residents will be allowed to return to their homes, with officials advising them to pack at least a week's worth of food and drinking water, as grocery stores operate at reduced capacity. Though rainfall in the area might aid in suppressing the fires, it could also lead to flooding, mudslides, and debris flows in the burn zones. Meanwhile, the FBI is offering a $10,000 reward for information that helps determine the cause of the wildfires.
