SATCAST provided a lead-time of approximately 45 minutes before achieving a 35 dBZ radar reflectivity and the line of storms was identified for initiation approximately 45 minutes before the issue time of the SPC watch. This shows the utility of SATCAST in nowcasting possible severe convective weather and highlight areas of development up to an hour in advance.
