The second image may look a bit foreign to some. This is vertically integrated liquid (VIL). VIL is the integration of reflectivity within a column of air. A higher VIL means there is more precipitation in a column of air. Typically with thunderstorms, high VILs can indicate hail. This is not always the case, however, so this tool cannot be used alone in the forecasting of severe thunderstorms.

Watch out for penny size hail or larger, and winds in excess of 60 MPH, as well as heavy rain and cloud-to-ground lightning.
