The surface front moves through about 4AM Saturday morning without upper air support. A few widely scattered showers are possible before daybreak.
The remnants of the front stalls to our south and the cloudiness breaks for sunshine through high cirrus clouds during the morning Saturday.
Sunday’s weather will depend upon the complex interaction between the developing tropical storm off the southeastern coast and a strong upper and surface low in the Midwest. Much uncertainty for the forecast period late Sunday through Wednesday.
