Initially, prob severe detected a small area for it’s algorithm and it tagged it with low severe probabilities. As the storm progressed, prob severe picked up a larger area for the object, and when it did that, the probabilities increased. This could indicate that the storm is gaining strength, but radar presentation has remained almost steady state. This could be a detection issue as when it picks up a larger area, the probabilities increase due to size.
