July 18 Severe Thunderstorm Mesoanalysis Values

Supercell Composite (SCP)- Higher values indicate a higher value for supercells

Energy Helicity Index (EHI)- Spinning motion combined with energy in the atmosphere. Values above 4 are considered dangerous

Significant Tornado Parameter (STP)- Values above 1 indicate potential for tornadic activity.
Values from the above 3 parameters indicate the single cell in South Wisconsin could go tornadic at some period in time.
We will be watching this cell because we believe it is in an environment dangerously favorable for tornadic motion and severe aspects.
