The upper trough will continue to interact with an arctic front near the Gulf Coast and across the Southeast, where the next round of wintry weather is forecast to impact locations from the lower Mississippi Valley, across the Tennessee Valley into the Mid-Atlantic states through Tuesday morning. This will be the last Storm Summary issued by the Weather Prediction Center for this event. Please refer to your local National Weather service office for additional information. Otto $$
