CWASP = The Craven-Wiedenfeld Aggregate Severe Parameter, named after NOAA researchers, is a multi-variable index that aggregates 33 weighted weather variables—such as instability (CAPE), vertical wind shear, and moisture—into a single score ranging from 0 to 99.

Scores below 50: Typically indicate a low probability of significant severe weather.
Scores of 50 to 70: Suggest an increasing likelihood of severe weather, including isolated instances of large hail or damaging winds.
Scores above 70: Highlight a highly volatile environment; historical data shows that the vast majority of strong to violent (EF2+) tornadoes occur when CWASP values exceed this threshold
