Supercell Composite Parameter (SCP)

Storm Prediction Center Definition: SCP

A higher number corresponds to higher values of three key ingredients for supercells: 1) directional shear, 2) speed shear, and 3) instability.

Significant Tornado Parameter (STP)

Storm Prediction Center Definition: STP

A higher number corresponds to higher values of four key ingredients for significant (EF2+) tornadoes: 1) directional shear, 2) speed shear, 3) instability, and 4) low cloud bases.

Chiclets

The values above represent the ensemble mean of daily (~6 a.m. to ~6 a.m.) sums of SCP and STP values for grids in the United States.

Larger numbers (darker colors) represent larger areal coverage non-zero SCP values.

Smaller numbers (lighter colors) represent smaller areal coverage of non-zero SCP values.

A lower number for a day does not mean zero risk, as the risk could be regional or localized in nature.
