About This Map

Lifted index is a measurement of the stability of an air mass at a given moment. Positive values denote stable air masses, and negative values denote unstable air masses. Negative values are an indication that strong thunderstorms may occur in the area. On our weather maps, lifted index is given in kelvins.
