Wider weather episode
An upper level wave moving through N CA/NV provided plentiful forcing for storms to develop on July 30. In fact, showers lingered overnight the night before across portions of the Sierra and NE CA. These storms produced robust outflows with multiple areas of blowing dust and one true haboob/dust storm. We also had flooding that closed a roadway that afternoon/evening along US-395 near the Red Rock area.
