Early morning fog

Friday, August 20, 2010
Heavy banks of fog drape the valleys of College Grove early Friday morning just as the sun rises over State Route 840 in Williamson County. The fog is the result of rain -- heavy in some areas -- falling over much of Middle Tennessee throught the middle of the week. Fog forms when the difference between the dew point and temperature is less than 4 degrees. (T-G Photo by Kent Flanagan)
