The severe thunderstorms developed in advance of a strong... Read More

Above-freezing ground temperatures caused snow melt in lower Minnesota, as seen in this GOES-16 true color imagery from RealEarth. Temperatures in the area reached a balmy 40 degrees Fahrenheit, dissipating what snow had accumulated. At the beginning of the animation, you can see a dark ‘V’ shape that is in... Read More
