Watch for a trace to up to a tenth-inch of ice accumulation in the Upstate, mainly around and north of the I-85 corridor.
The southern mountains/foothills get close to a quarter-inch or more of ice, as do the northern mountains and foothills…where sleet will also mix in.
The southern Upstate and the western mountains will be warm enough for just rain with the rest of this system.
Watch for difficult travel, and the warning areas might get spotty power outages if they hit the higher end of the ice accumulation.
Here is a list of current accidents on the SC Highway Patrol Website.
