SRH is a measure of rotation potential.
Some critical values SRH:
If showers form:
150-300: supercell development possible with large CAPE, risk for weak tornadoes (F0, F1)
300-450: supercell development possible with small CAPE, risk for strong tornadoes (F2, F3)
>450 : large risk for supercell development, risk for violent tornadoes (F4, F5)
