- Weakening outflow boundary and gust front
- W941999S
- This weakening outflow boundary and gust front has lost its lowest clouds as it moves farther from a dying area of showers. The outflow continues to push forward because it is denser than the warm air it displaces, but the air is modifying and becoming relatively drier as it warms up. Two distinct ledges of cloud remain visible from separate stronger phases in the surging cool air.
