The extreme heat poses significant health risks, particularly for vulnerable populations such as the elderly and those with pre-existing conditions. Prolonged exposure to high temperatures can lead to heat exhaustion or heat stroke. Severe thunderstorms and flash flooding threaten property and infrastructure, with risks of power outages, road closures, and localized flooding. Areas like Kansas City, Tulsa, and Wichita are at heightened risk for destructive winds, large hail, and tornadoes. By Sunday, major urban centers like New York City, Philadelphia, and Washington, D.C., could experience damaging winds and hail, further amplifying the weekend's weather challenges.
