Warn-on-Forecast uses computer models and machine learning to project tornadoes at long lead times.

Long lead time can give forecasters greater confidence to issue warnings and narrow down the areas most likely to be impacted.

Warnings have traditionally been based on detection or indicators of severe hazards using National Weather Service Doppler radars.
