Surface-Based Lifted Index (C) & Convective Inhibition (J/kg)

SBLI (Surface Based Lifted Index & Convective Inhibition) is the Lifted Index at 500-mb, based on the surface parcel, and the convective inhibition for the same parcel. These fields are meant to identify areas of surface-based CAPE and minimal convective inhibition, which suggests some threat for surface-based thunderstorms.
