What happened

The episode as NWS PQR wrote it up.

A shortwave trough combined with favorable upper level dynamics, mid-level instability and plenty of sub tropical moisture resulted in convective showers over the Portland metro area. Heavy rain from these showers resulted in significant flooding for the Beaverton/Hillsdale. Four homes, four apartments, the Winterhawks Skating Center, and a community center pool suffered damage from the heavy rain.

What forecasters said that day
