- W992577S
- A storm cloud and wind shift line has just passed. The storm at left is in an outflow phase, as a surge of fresh cold air pushes its flanking line forward as a gust front. Under it, low clouds and scud are forming and joining the base. The air rises along the dark base, then builds towers which feed to the left to maintain the storm for a long time.
