| Abstract | Across North America, hailstorms are responsible for at least $10 billion in annual damage. This cost is expected to increase as housing and commercial developments expand in hail-prone areas. To fill the current gaps in hail science, the In-situ Collaborative Experiment for the Collection of Hail in the Plains (ICECHIP) sought to improve radar-based hail detection, hail modeling, and hail forecasting by cultivating a comprehensive dataset from the one of the first U.S. hail-focused field projects in over 40 years. In this study, field sounding data from a Texas hailstorm during ICECHIP on 25 May 2025 was simulated using Cloud Model 1 (CM1) to examine whether convection initiates and develops differently in an idealized environment compared to the observed mesoscale environment. When compared to KLBB reflectivity observations, CM1 simulated reflectivity 6 km above ground level resolved two updrafts with opposing motion despite their different initiating mechanisms. Additionally, CM1 3-h surface precipitation accumulation resolved totals of up to 80 mm present in Multi-Radar Multi-Sensor (MRMS) 3-h Quantitative Precipitation Estimation (QPE) data, but swaths varied in shape and size due to differences in storm structure and coverage. |
