- W904126Z
- Storm structure: In this forward propagating storm to the northwest, air flows along a combined gust front and flanking line toward a distant low base on the forward side of a hidden rain core. The axis is formed by low-level winds but above it, the grooves in higher layers show that air moves out and forward with height.
