Experts are hoping that a weather modification program will increase water from snow storms, possibly ending Colorado’s drought.  Andrew Rickert is spearheading cloud seeding in the state. He leads Colorado’s weather modification program.  In Western states, some water providers, ski areas and power companies have all injected silver iodide droplets into winter clouds for decades. In those areas, the winter snows that collect on mountain ranges provide upward of 70 percent of annual precipitation. The idea is that the droplets provide a nucleus within a cloud around which water can coalesce, forming snowflakes.
