Lightning Probability: NextGen™ Customers

Lightning Probability provides the probability of lightning occurring at a given location and time. It is designed for operations where lightning itself is the primary weather hazard.

Lightning Probability is available with NextGen™ within CONUS and provides forecast guidance up to 36 hours ahead.

Key Features

• Forecast coverage: Up to 36 hours ahead within CONUS
• Probability: Displayed as a percentage from 0–100%
• Map visualization: View forecast lightning probability directly on the map
• Insights and Alerts: Use Lightning Probability when configuring lightning-based operational thresholds

When to Use Lightning Probability

Use Lightning Probability when your operational decision is specifically driven by the likelihood of lightning.

If your operation is affected by thunderstorms more broadly, including other potential convective hazards, use Thunderstorm Probability instead.

For an additional short-term view of lightning risk over the next 60 minutes, use Lightning Nowcast.
