Highway 36 in northern Missouri is something of a dividing line as to when the ice storm warning begins.
The National Weather Service includes Caldwell, Livingston, and Linn counties of the Green Hills Region in an ice storm warning beginning at noon.
The rest of the Green Hills counties, or basically north of U-S 36, have the ice storm warning beginning Saturday evening at 6.
We asked Meteorologist Jared Leighton of the National Weather Service why?
