Convective Available Potential Energy (CAPE) and Lifted Index (LI) charts are used to forecast the likelihood of thunderstorms. Forecast CAPE values are shown by the coloured shading with yellows, oranges and reds indicating a progressively increasing chance of thunderstorms. LI is shown by the contours with values below 0 indicating greater instability and an increasing chance of thunderstorms.
