Transcript for Severe Thunderstorms Darken Skies Across the US
Dangerous weather worsening overnight. Flash flooding and waters rising rapidly sweeping families away. Ginger tracking it all. More than 170 severe weather reports from coast to coast and we get in a little closer. Part of the fuel for all the storms, that striking cold front. This morning Memphis in the 70s. Kansas hit a record low of 54. Unruly storms across the nation. Hail and floodwaters swallowing Colorado neighborhoods. Fierce downpours in Kansas. And in New York and New Jersey, cars overtaken by water. Up to 2 inches falling fast. All the cars and they were pulling through. Their waves were hitting us and moving us. In Ohio one family's car hydroplaning and being whipped away by flash flooding. The father grabbing his daughter and hanging on a tree. His wife did not drown. The water carrying her four miles before she too climbed to safety. 2,000 miles southwest, a harrowing water rescue in Phoenix. A woman pulled from her submerged car. Time lapse capturing the monsoon storms dumping almost 2 inches of rain in just an hour. Images inside the storm striking a hit on the freedom tower, the library of congress in D.C. Struck too and in Philadelphia, a teenage boy is in stable condition after he was struck by lightning. So who needs to look out for those watches later? Wyoming, Colorado, a little area there, also from North Carolina up through Vermont and new Hampshire. Strong wind, large tornadoes and, of course, we could see hail. Excuse me, isolated tornadoes. Not large. I wanted to sit on this. It is cold but some people are telling me they love it. Chicago is saying this feels good. Feels like end of September As long as they like it. Keep it. Keep it there. Hey, ginger, thank you.
