"Training" Thunderstorms

When thunderstorms continue to move over the same area, meteorologists refer to this as "training". Unfortunately, it looks like that is what we are dealing with early this morning. A stalled front near the Illinois/Wisconsin line combined with a strong low-level jet fueling moisture and instability into eastern Iowa is generating thunderstorms that continue to move from eastern Iowa across northern Illinois.

The ground is already saturated across much of the Stateline due to heavy rains earlier in the week, especially to the north of Rockford. Any additional rainfall will quickly drain into creeks, streams, and rivers that are running high and could cause flash-flooding at a moment's notice. Some areas could see in excess of 4" of rainfall.
