Significant Tornado (SigTor)

A composite index that includes 0-6 km bulk wind shear, 0-1 km storm-relative helicity, surface based CAPE, surface parcel CIN, and surface parcel LCL height. Values greater than 1 are indicative of increased potential of significant tornadoes.

The contours are the Lifted Condensation Level or LCL. A lower LCL typically increases tornadic risk because it is indicative of air parcel acceleration occurring closer to the surface.
