Encouraging snowing in Colorado could be freezing us in the upper Midwest

In Colorado more than a hundred cloud seeding machines are set up in mountainside backyards, fields and meadows. 
Their goal is the same: to “seed” clouds with particles of silver iodide, a compound that freezing water vapor easily attaches to. 

That makes ice crystals, which eventually become snowflakes.
