Ice Crystals?! Really? That's neat! I woulda never thought of ice. How bout the ice that came off the lake and slammed into those poor peoples houses? Did you see that on the news? Wild huh...I never heard of that happening either.
Yes, it from cirrus clouds, specifically! They are high up in the atmosphere and are made mostly of ice crystals.
I did see the ice jams overflowing onto the houses. Pretty crazy and now it is in the upper 90's there today! Brings a new meaning to "Iceberg right [in bed]!"
