Here in Maryland, it's known as freezing rain. The temperature of the rain is lowered below freezing as it drops and as soon as it hits a surface, it instantly freezes. Ice on everything, trees, grass, roads, power lines,everything. The power companies are run ragged when it happens with downed power lines. The roads are treacherous, but man the trees are transformed into beautiful crystalline structures. I like to take a hike when we get the freezing rain. The trees are magical. Just be very careful under branches because they can break off and drop at any time, even when you are walking right under them.
