A pecan tree is silhouetted against fog surrounding the Old Court House Wednesday evening. The fog covered Vicksburg as a cold front moved in, bringing a chill to Warren County Thursday and this morning. The National Weather Service in Jackson predicted Saturday will be clear but cold with highs in the mid-30s. A chance of rain or snow remained for Sunday, with temperatures forecast to be in the lower 30s. (The Vicksburg Post/PAT SHANNAHAN)
