Recent advances in high resolution atmospheric weather modeling include the introduction of the enhanced RUC13 (13km) which assimilates 3-d radar reflectivity. In order to study the impact of these improvements on local modeling efforts at WFO Miami, a experiment has been designed for the 2011 convective season using the WRF Environmental Modeling System (WRFEMS) released and maintained by the NWS Science and Operations Officer Science and Training Resource Coordinator (SOO STRC). Two different configurations have been put in place for the 2011 convective season: 1) a WRF ARW 9:3 km nest running 6 times a days out to 18 hours using for initial and boundary conditions (BC) the enhanced RUC13; 2) a WRF NMM 9:3 km nest running out to 48 hours 8 times a day using the enhanced RUC13 for initial conditions and the Global Forecast System (GFS) for boundary conditions. Additionally, both configurations will use NASA Short-term Prediction Research and Transition Center (SPoRT) high resolution MODIS/AMSR-E composites providing superior details of the Sea Surface Temperatures across surrounding ocean areas and NASA's high resolution Land Information System (LIS) surface datasets. The focus of the analysis will be on short term convection with emphasis on higher impact events and it will include a subjective forecasters based assessment as well as an objective component based on Stage IV gridded precipitation data and grid scale Threat Score analysis. This paper will present the results of this experiment.
