%X A case study of an squall line associated to a frontal system over southern Brazil on 08 th of September, 1999 is presented. This weather event caused heavy precipitation, lightning and strong wind gusts in Parana State. The analysis was done using the Tropical Rainfall Measuring Mission (TRMM) data and the National Centers for Environmental Prediction (NCEP) reanalysis. The results show that NCEP analysis did not allow the exact identification of the dynamically favorable areas for the convective activity onset . On the other hand, TRMM's analysis depicted very well the presence of an squall line organized in two distinct bands of precipitation. The first one (equatorward ) is well organized and associated with high rainfall rates while the second one (poleward) is associated with stratiform rainfall pattern.
