The K and TT values were satisfactorily simulated and LI index were reasonably simulated by WRF. The values of CAPE showed the largest differences compared with observations. When we analyzed the behavior of K, TT and LI indices with the METAR code, it was observed that the simulated extreme values by WRF occurred at times to unstable weather records in the airports.153-162porInstability indicesStormsWRF ModelAnálise Preliminar dos Índices de Instabilidade a Partir de Simulações Realizadas com o Modelo Weather Research and Forecasting (WRF) para o Sul do BrasilPreliminary analysis of instability indices from simulations with weather research and forecasting (WRF) model for the Southern BrazilArtigo10.11137/2017_2_153_1622-s2.0-85024118877
