- Storm cloud with breaks from subsidence on the outflow boundary
- W000544Z
- Change is imminent as a boiling storm cloud invades the sky. A severe storm lower left has sent an outflow boundary past which now appears as a bright wall with dark base. This boundary also doubles as the storm's inflow axis, or flanking line. Overhead in the cooler outflow air, the sky is variable with breaks from the subsidence.
