Understanding Hail Forecasts During Severe Weather

Hailstorms can cause significant damage, making it crucial to understand hail forecasts during severe weather events. This guide provides essential information to help you interpret these forecasts effectively.

What Are Hail Forecasts?

Hail forecasts predict the likelihood and severity of hail during severe thunderstorms. These forecasts are issued by the National Weather Service (NWS) and include:

• Severe Thunderstorm Outlooks: Assess the potential for severe thunderstorms, including hail.
• Hazardous Weather Outlooks: Provide information on expected severe weather hazards, such as hail.
• Area Forecast Discussions: Offer detailed analyses of weather conditions, including hail potential.

How Are Hail Risks Categorized?

The NWS categorizes hail risks using a scale from "Marginal" to "High":

• Marginal Risk: Low chance of severe hail.
• Slight Risk: Slight chance of severe hail.
• Enhanced Risk: Moderate chance of severe hail.
• Moderate Risk: Significant chance of severe hail.
• High Risk: Very high chance of severe hail.

For example, a "Moderate Risk" indicates a 45% or greater chance of severe hail within 25 miles of a point. (weather.gov)

What Size Hail Is Considered Severe?

Hail is classified as severe when it reaches 1 inch (quarter-sized) or larger in diameter. Hailstones of this size can cause significant damage to vehicles, roofs, and crops. (weather.gov)
