Cloud Seeders Unable to Help Ease Drought

Cheyenne, WY – Conditions haven't been favorable in
recent weeks for an experiment to see if cloud seeding can boost snowfall in three mountain ranges in Wyoming. The study involves spraying silver iodide above the Medicine Bow, Sierra Madre and Wind River ranges. The chemical is sprayed using both aircraft and ground-based generators. Researchers missed the first half of this winter because they hadn't finished installing the generators. But lately the weather hasn't been conducive to cloud-seeding. Bruce Boe is director of meteorology with the company running
the experiment. He says moisture has been below average, especially in the Wind
River Range. He says recent warm weather hasn't been good for cloud seeding, either.
