Elevated Potential Instability (EPI) can develop within cyclones impacting the United States and can lead to enhanced vertical motions within the clouds. The enhanced vertical motions can influence how ice crystals grow and snowfall characteristics at the ground. This work presents results on how frequently EPI occurs, where EPI occurs, EPI characteristics, and hydrometeor vertical motions within these layers. The microphysical properties of ice within EPI layers are presented for a case study during the Investigation of Microphysics and Precipitation for Atlantic Coast Threatening Snowstorms (IMPACTS) field campaign to demonstrate the skill of a neural network at retrieving microphysical properties from radar data.
