Oklahoma City Major Flooding

What happened

An area of heavy rain and thunderstorms moved through portions of Oklahoma late Thursday morning, prompting a flash flood emergency. Reports of 2-4’ of rainfall in a short period of time resulted in flash floods. Numerous roads were closed due to flooding and firefighters performed more than a dozen high-water rescues. Cars were nearly completely submerged in parts of the city.

GSL’s impact:

Two members of GSD’s experimental ensemble depicted a scenario of long-lasting thunderstorms that had the potential to cause flooding. An ensemble is a collection of model forecasts each with slightly different rules. If several of the ensemble members predict the same scenario, a forecaster has more confidence that the scenario could happen.
