“What is cloud seeding?”

There are several types of cloud seeding, but the one done at the Rogue Valley International Medford Airport involves releasing a balloon that disperses crushed dry ice. Other ways include shooting a canister into the fog/clouds with silver iodide or dry ice or flying through/over the clouds to release the chemical. This chemical essentially provides a nuclei for ice/water droplets to form on and create larger droplets that can fall to the ground as snow, rain or even freezing rain. When fog/cloud molecules turn to rain or snow they disperse and clearer skies develop and planes are able to depart and land at the airport!
