Conditions will favor the formation of fog from portions of Tennessee and North Carolina to New England during morning hours of the latter part of this week.
Diminishing wind, recent drenching rainfall and a clear sky over head will allow fog to form in the valleys again Friday morning in portions of the East and interior South.
While the fog is likely to stay away from most of the major I-95 cities in the mid-Atlantic and New England, folks flying out of secondary airports first thing in the mornings may experience delays. Also fog patches can appear in some of the suburbs.

This also means that visibility may be poor over stretches of interstate highways that pass through the valleys within the Appalachians, including I-40, I-64, I-70, I-77, I-79, I-80, I-81, I-83 and I-99.
Thursday morning, patchy dense valley fog reached from western North Carolina to Vermont and New Hampshire. Near-zero visibility occurred in Springfield, Vt.; Franklin, N.C., Middlesboro, Ky. and Marion, Va. Visibility was reduced to one-quarter mile over the broad Susquehanna Valley in central Pennsylvania. Freezing fog occurred in parts of upstate New York.
During Friday morning, fog may favor the eastern side of the Appalachians in portions of North Carolina, Virginia, central Maryland, central and eastern Pennsylvania and central and southeastern New York.
If you will be traveling within these areas, expect delays and allow extra time for your ventures.
In light wind situations, cool air tends to collect in the valleys. As this air cools, it becomes saturated under the right conditions.
Since the rivers are relatively warm this time of the year, they tend to release extra moisture into the local environment.
