spatial domain for each day is different and generally not CONUS-wide, but the domain usually covers a large portion of the CONUS, including most tornadoes on the given day and many nontornadic storms. At each 5-min time step, GridRad includes four variables on the 3D grid: reflectivity, spectrum width, vorticity (twice azimuthal shear), and divergence (twice radial shear). The RAP is a nonhydrostatic mesoscale model with 13- or 20-km grid spacing and covers much of North America, including the full

). Annual rainfall is commonly less than 750 mm ( Leal et al. 2005 ), and it is highly variable ( Moura and Shukla 1981 ). The region experiments a peculiar intra-annual rainfall regime, with a maximum in March–April over the north and the center part and in November–March over the southern part. Cerrado is a tropical savanna covering 22% of Brazil’s territory. The overall amount of rain is usually between 800 and 2000 mm yr −1 ( Ratter et al. 1997 ), mostly distributed between October and April

SREF analyses herein are output to a grid with 32-km horizontal grid spacing (NCEP grid 221). SREF configuration details are summarized in Table 2 . Table 2. SREF member specifications, adapted from Du et al. (2015) . Initial conditions (ICs) are taken from the operational Rapid Refresh (RAP; Benjamin et al. 2016 ), the National Centers for Environmental Prediction’s (NCEP’s) Global Forecast System (GFS), and the North American Mesoscale Model Data Assimilation System (NDAS). IC perturbations
