The energy associated with both Laura, the non-tropical low, and the cold front will move through in separate batches. Showers and rain will move through during the overnight hours. There may be a break in the action Saturday morning, but rain returns around noon and continues though the mid afternoon. Total rain about 1 inch, locally higher.
The GFS (new pre-release version) has rain ending around 5PM with even some sun possible later Saturday afternoon. The HIRESW has similar forecast, but has additional showers and clouds after 8 PM with the actual cold front passage.
