Caption: On Dec. 21 at 2:29 a.m. EST, the AIRS instrument aboard NASA's Aqua satellite captured this infrared image of the massive low pressure area that caused a major snowstorm in the Midwest and beyond. The darkest blue and purple (-63.6 Fahrenheit/-53.5 Celsius) areas indicate the highest clouds and coldest cloud top temperatures, where precipitation is heaviest.
