Hailstorms

Probability of Severe Hail (Diameter of at Least ¾ in): The animation of the percent probability of severe hail (diameters of at least ¾ inch) shows that most states east of the Rocky Mountains experience large, damaging hail with the exception of the extreme northeast. Probabilities are based on hail occurring within 25 miles of a point on a particular day. Note that severe hail is most common in the Southern Plains.

Probability of Significant Hail (Diameter 2 in. or Larger): An animation of the percent probability of having hail 2 inches or larger in diameter within 25 miles of a point on a particular day shows that the most significant hail occurs in the southern Plains early in the thunderstorm season and migrates northward to the Central and Northern Plains later in spring and summer.
