Very rare ice storm shaping up for coastal South Carolina. Cold air at the surface to undercut moist air above with FROPA tonight, then a surface low to ride up along the front which should be positioned just offshore tomorrow, drawing up and wrapping around plenty of moisture. Almost perfect and necessary conditions for any ice storm to impact this area.
What will be very interesting is the sociological impacts. I would venture to say the vast majority of folks down here in Charleston, SC have no practical experience in dealing with a full-blown ice storm, let alone actually driving on ice-glazed roads. Moreover, the electrical grid infrastructure - already relatively fragile - will be at significant risk for widespread and probably prolonged power failures. This area relies on an extensive network of bridges to connect everyone -most of which may be forced to close in the event of icing. And the trees! Besides being extensive, many retain their foliage during the winter months. Even 1/2" of ice will result in tremendous weight on the branches, and 1" of ice on the trees could result in significant damage to structures from breaking limbs.
Lots of local buzz, but if it really comes together as expected, I'm not sure folks have any idea what we may be in for.
