On Dec. 12 at 0429 UTC (Dec. 11 at 11:29 p.m. EST) the Atmospheric Infrared Sounder or AIRS instrument aboard NASA's Aqua satellite analyzed cloud top temperatures in infrared light. AIRS found cloud top temperatures of strongest thunderstorms in several area around the center. Those temperatures were as cold as or colder than minus 80 degrees Fahrenheit (minus 62.2 degrees Celsius). They were embedded in a large area where cloud top temperatures were as cold as or colder than minus 70 degrees Fahrenheit (minus 56.6 degrees Celsius). Cloud top temperatures that cold indicate strong storms that have the capability to create heavy rain.
