This is the 'Heat Transfer System' that displaced the Arctic Air to the lower forty-eight states. This is the Chugach Range in Alaska. The snow is there but sparce. The cloud is not superimposed in this picture. The photographer can attest to that. I'll list his home photo shop as well. The clouds are Global Warming clouds. They are carrying hot air over the northern icefields to cool Earth. The clouds are very low to accomplish exactly that. They are also dangerous clouds that can spawn tornadoes as mild as 'Snow Devils' and greater. I sincerely doubt a tornado of this nature will become greater than a Category 2. The purpose of these systems are to distribute heat and whatever end that happens it happens with low pressure systems that can become very intense. That is an incredible picture. I'll post the other one as well. Thank you so very, very much.
