The Storm Prediction Center's Roger Edwards maintains a neat gallery of weather images. Roger selects "interesting, beautiful, educational, and/or unusual radar, satellite, or analytical imagery dealing with any weather subject." He also includes some analysis of what's in the image, complete with references.
KTXS Welcomes submissions of weather pictures. Photographs should be in GIF or JPG format. By submitting photographs, you grant KTXS permission to display photos on the air and on this website.
