KNOW IT ALL: Wednesday’s Top Stories at NBC News


This NOAA satellite image taken Wednesday, Dec. 24, 2014, at 12:45 a.m. EST shows a large area of heavy thunderstorms and rain showers affecting most of the southeastern United States due to a complex low pressure system with multiple frontal boundaries moving eastward. A main cold front extends from this system well into the Gulf of Mexico which is causing a line of thunderstorms to form. Another stationary boundary across the eastern seaboard is causing scattered areas of rain showers to develop especially over the Carolinas and Florida. Parts of the northern central United States are also experiencing scattered areas of rain and snowfall due to a surface trough associated with this complex system. (AP Photo/Weather Underground) AP
