00:00 How Much Freezing Rain is Too Much? The Weather Channel meteorologist Paul Goodloe shows it doesn't take much freezing rain to cause problems.

Winter Storm Octavia has finally exited stage right Tuesday, having dumped up to 18 inches of snow as well as showering rain onto a swath of sub-freezing land, leading to damaging ice accumulations in some areas.

Octavia blanketed parts of a swath from Missouri to Virginia with more than 6 inches of snow. As of early Tuesday morning, the top reported snowfall total was 18 inches near Coleman in far eastern Kentucky.

A mix of sleet and freezing rain slickened roads and triggered power outages affecting well over 300,000 customers in 14 states and the District of Columbia. Up to three-quarters of an inch of ice accumulation was reported in eastern Tennessee. For more snow and ice totals, click here .

Octavia then spread snow into the Northeast, and dusted snow-weary southeast New England on its way out to sea.

Accumulated sleet/ice or flash freezing of lingering liquid on pavement also lead to slick roads from North Carolina and Upstate South Carolina westward into the Tennessee Valley on Tuesday morning.

Ice-affected Middle Tennessee may not warm above freezing until Friday or Saturday as another reinforcing shot of cold air is expected.
