The episode as NWS FFC wrote it up.
A weak stationary front was stretched across the area, with an upper trough along the Eastern Seaboard. Multiple shortwaves continued across the area. Scattered afternoon showers and thunderstorms developed mainly in the vicinity of the trough, and in general relative humidity values remained too high for dangerous fire weather conditions.
