Airman James Leos, 28th Operations Support Squadron weather apprentice, uses a pair of binoculars with a laser range finder to help forecast weather conditions at Ellsworth Air Force Base, S.D, May 30, 2018. The weather flight has to stay on the lookout for changing weather conditions so the flying mission is not affected by any surprise changes in the weather.
