             abstract = "The GOES-16 mesoscale domain sector (MDS) scans with 1-min 
                         intervals are used in this study to analyze a severe thunderstorm 
                         case that occurred in southeastern Brazil. The main objective is 
                         to evaluate the GOES-16 MDS rapid scans against the operational 
                         full-disk scans with lower temporal resolution for nowcasting. 
                         Data from a C-band radar, observed sounding, and a ground-based 
                         lightning network are also used in the analysis. A group of 
                         thunderstorms formed in the afternoon of 29 November 2017 in an 
                         environment of moderate convective available potential energy 
                         (CAPE) and deep-layer shear. The storms presented supercell 
                         characteristics and intense lightning activity with peak rates in 
                         excess of 150 flashes per 5 min. The satellite-derived trends with 
                         1-min interval were skillful in detecting thunderstorm 
                         intensification, mainly in the developing stage. The decrease in 
                         cloud-top 10.35-mu m brightness temperature was accompanied by 
                         increases in ice mass flux, concentration of small ice particles 
                         at cloud top, and storm depth. In the mature stage, there is no 
                         evident trend in the satellite-derived parameters that could 
                         indicate storm intensification, but the cluster area expands 
                         suggesting cloud-top divergence. The 1-min rapid scans indicate 
                         greater lead time to severe weather relative to 10- and 
                         15-min-resolution imagery, but also presented numerous false 
                         alarms (indication of severe weather but no occurrence) due to 
                         oscillations in the satellite-derived parameters. The parameters 
                         calculated every 5 min presented better skill than 10 and 15 min 
                         and fewer false alarms than 1 min.",
