What happened

The episode as NWS TFX wrote it up.

The typical severe weather setup across the region - surface moisture advected in from the east with stronger west to southwesterly flow aloft - developed across the region from June 13-15. Fog and low clouds inhibited destabilization on June 13. Initially surface moisture was less quality on June 14, but increased for June 15, which was the most active severe day.

What forecasters said that day
