We have another tropical depression. This one is in the western Gulf of Mexico. It’s forecast to move northeast tonight into the weekend just west of the Tennessee Valley. It could become Tropical Storm Olga later today. The system will get absorbed along a cold front over the next couple of days. Regardless of development, it will enhance rain chances across the Mississippi and Tennessee Valleys through Saturday. That moisture moves north across the Ohio Valley and Great Lakes by Sunday.
Here is the official track:
