      About Today

      Read the SPC Forecast Discussion.

      Convective outlooks are issued for the following eight days (issued separately for Day 1, Day 2, Day 3, and Days 4–8), and detail the risk of severe thunderstorms and tornadoes during the given forecast period, although tornado, hail and wind details are only available for Day 1. Days 2 and 3, as well as 4–8 use a probabilistic scale, determining the probability for a severe weather event in percentage categories. Wikipedia
