Severe Weather Outlook Maps

SPC convective outlook maps showing tornado, severe weather, damaging wind, and large hail risk across the United States. Data from NOAA's Storm Prediction Center, updated multiple times daily.

Tornado Outlook

Today's Tornado Outlook (Loading date...)

This map shows areas where tornadoes are most likely to form today, based on data from NOAA's Storm Prediction Center. Colored areas show the probability of a tornado within 25 miles of any point. Even 5% is significant β€” that's 5x normal odds. Dashed outlines show Conditional Intensity Groups (CIG): CIG1 = brief/weak tornadoes, CIG2 = strong, CIG3 = violent/long-track.

This map shows areas where tornadoes are most likely to form tomorrow, based on data from NOAA's Storm Prediction Center. Colored areas show the probability of a tornado within 25 miles of any point. Dashed outlines show Conditional Intensity Groups (CIG): CIG1 = brief/weak tornadoes, CIG2 = strong, CIG3 = violent/long-track.

Day 3 Outlook

Day 3 Severe Weather Outlook (Loading date...)

This map shows the combined severe weather probability for Day 3 (two days from now), based on data from NOAA's Storm Prediction Center. Day 3 outlooks use a combined probability approach covering all severe hazards (tornadoes, wind, and hail). As the forecast period gets closer, these are replaced by individual hazard outlooks.
