Transcript for Warm Weather Brings More Problems
First, finally a break from this brutal, brutal winter. It's warming up all over the country. It's the thaw, is it coming too fast creating dangerous, even deadly conditions as all that melts fast. Is the good news bad news scenario. It is. Issues popping up. Very heavy rains from parts of West Virginia where lots of snow cover, severe weather in eastern Tennessee and freezing rain in central Pennsylvania. This all on top of 34% of our nation that is covered in snow. So anywhere above that line covered in snow and the next three days going to put heavy rain on top. Flooding is only one of the threats. This morning, more than a third of the nation is still blanketed in snow and ice. At least five major cities seeing record snowfall in 2014. But today, the melt is on. Minneapolis already soaring to 44 Tuesday. The quick thaw causing roads to buckle creating huge backups along I-35. And in Chicago, the thermometer skyrocketed to 46 degrees. The warmest temperature in almost two months. Chunks of ice falling off buildings downtown. This major meltdown though could mean flooding and inevitably potholes. Those dangerous gaping holes formed when groundwater freezes and then expands rapidly. Way too many around here. They're all over the place. Reporter: Experts say, hitting a pothole can exert more force on a vehicle than a 35-mile-per-hour car crash. They are aen to nearly $5 billion of automobile insurance claims each year. So while some of these Numbers may look exciting, high temperatures the next four days look at Indianapolis, 60. Louisville, almost 70. It's a brief warm-up. That means cold air is on the back identify and that means we've got severe weather. Tonight in parts of eastern Kansas and then tomorrow is the big day where we see severe weather including isolated tornadoes, damaging wind and, of course, the potential for large hail so anywhere from Detroit down to parts of Louisiana. Tomorrow, big day, George. Never lets up. Okay, thanks very much.
