A dangerous heatwave will scorch the central and eastern US, bringing the year's hottest temperatures to the Midwest and Northeast. Extreme heat watches and advisories are in effect, with highs in the 90s expected, potentially reaching 100 degrees in some cities. The heat, coupled with high humidity, will last into next week, posing risks to those without air conditioning. The National Weather Service urges precautions such as staying hydrated and limiting outdoor activity during peak heat.
