What Is Probability Of Severe Hail?
A radar estimate of the chance a storm is producing hail at least 3/4 inch across. In technical terms: A WSR-88D hail algorithm output giving the probability of hail 0.75 in (19 mm) or larger, computed from the Severe Hail Index relative to a warning threshold tied to the freezing-level height.
Also called: POSH
