- Wall cloud evolution: gust front with Arcus and developing updraft
- W941059Z
- Wall cloud evolution, 1 of 2. A gust front with Arcus has a developing updraft and mesocyclone above it. An outflow surge from the right converges with the general cold pool moving forward along the axis to force air upward. Enhanced by a sharp rain foot, rising air forms strands of scud in mid-air in this incomplete, early stage wall cloud. See W941070Z next.
