• Tornado warnings and severe thunderstorm alerts remain active around Philadelphia after radar detected potential twisters near King of Prussia and Plymouth Meeting with winds up to 70 mph.
• Chicago recorded between 2.5 and nearly 7 inches of rain in under two hours overnight July 8–9, leading to flash flood warnings and stranded vehicles in submerged underpasses.
