Abstract One important aspect related to the management of water resources under future climate variation is the occurrence of extreme precipitation events. In order to prepare for extreme events, namely floods and droughts, it is important to understand how future climate variability will influence the occurrence of such events. Recent advancements in regional climate modeling efforts provide additional resources for investigating the occurrence of these extreme events at scales that may be useful for regional watershed modeling. This study utilizes data provided by the North American Regional Climate Change Assessment Program (NARCCAP) in order to investigate the occurrence of extreme precipitation events. The NARCCAP program utilizes six regional climate models (RCMs) driven by multiple atmosphere-ocean general circulation models (AOGCMs) focusing on the North American continent. Currently data from five RCM-AOGCM combinations is publicly available from NARCCAP. A comparison between observed (via TRMM satellite and in-situ data) historical precipitation events and NARCCAP modeled historical conditions was performed in order to investigate the reliability of the regional modeling efforts. Future scenarios provided by NARCCAP efforts, forced using the A2 SRES scenario, were also investigated in order to capture the expected variation of these events under future climates.
