Abstract: Most operational radar systems to date produce data with volumetric update times that are insufficient for capturing some of the rapidly evolving processes of hailstorms. Recent advances in rapid-scan radar technology and innovative approaches to obtain faster scans have paved the way for a better analyses of hailstorms. This study utilizes NSSL's research WSR-88D S-band radar, KOUN, to examine rapidly evolving polarimetric features in hailstorms. Quantities such as rate of hail descent and changes in the updraft can be calculated through the analysis of these rapidly evolving polarimetric features, which can increase forecaster confidence in hailstorm evolution and hail sizing. Multi-Radar Multi-Sensor (MRMS) products were generated using KOUN data, which captured the full lifecycle of a hailstorm, including the cyclic evolution of hail production and its relation to tornado production. These data were compared to KTLX to explore what features would not be resolved without a rapid-scanning radar system. Rapid-scanning radar observations provided more details on storm-scale processes related to hail, which can aid in operational forecasting and give insight into future operational phased-array radar benefits.
