- Thunderstorm cloud initiation, the first stage lacking organization
- W021416Z
- Thunderstorm cloud initiation first stage. The first storm of the day darkens the sky. Lack of organization makes it hard to read but the two obvious parts are a thick but uneven anvil at right and a rain-free updraft base lower left, plus a stiff wind blowing straight toward the darkest area. This storm is back-building and will quickly become severe as it develops a controlled inflow-outflow relationship.
