Support For Supercells: S-strong, O-OK, M-Marginal, P-Poor
VGP - Values greater than 0.2 suggest an increasing possibility of tornadic storms
STP - Values greater than 1 suggest an increasing possibility of tornadic storms
SCP - Values greater than 1 suggest an increasing possibility of supercells and
tornadic storms
Craven Sig Severe - Values greater than 20 suggest an increasing possibility of
sig severe storms
