Severe Weather Threat Index (SWEAT) measures thunderstorm potential by examining low-level moisture, convective instability, jet maxima, and warm advection.

> 272 Stable. Thunderstorms Unlikely.
273 - 299 Slight Risk. General Thunderstorms.
300 - 400 Moderate Risk. Approaching Severe Limits.
401 - 600 Strong Risk. Few Severe Thunderstorms/Isolated Tornadoes.
601 - 800 High Risk. Severe Thunderstorms/Scattered Tornadoes.
> 800 High Wind Damage, But Not Favorable For Severe Weather.
