Case study: February 2nd, 2017

On this day a squall line impacted São Paulo metropolitan region, Campinas, and other cities in the state. Although the storms were not as severe as some that occurred in the past January, the rains led to local flash floods (news here and here). This case is interest in particular from the modeling point of view.
