An upper-trough shifting through the Ohio Valley into the Central Appalachians will drag a front through the Tennessee Valley overnight. Along and ahead of the boundary, scattered to (at times) widespread light showers will continue to push across the area. Between 06-09z, this activity will begin to wane over the Plateau and favor the Mountain zones and areas generally along and west of the I-75 corridor, before tapering off areawide after 12z. Low clouds will linger through the night. However, in areas where shower activity wanes late tonight, the calm winds and moist boundary layer conditions will result in some areas of fog through early Wednesday morning. The clouds and showers will keep low temperatures on the mild side once again, in the upper 40s to lower 50s.
