Supercell and Derecho composites for

Probabilities are not based on wiether or not supercells or a derecho will occur. aka 30% probability of derecho composite at 3 doesn't mean 30% chance a derecho will happen.
The 'composite parameters' are based on the mean(average) calculations off atmospheric conditions where these types of storms have initiated. Higher values (between 1-6 (or higher)) tell us that the calculations put in (aka: cape, windshear, etc) are higher and more suitable for that type of storm. Having lower composite numbers for a derecho and vice versa does not mean it is less likely for another type of severe weather occurance.
