.DISCUSSION...
A dry cold front currently located in northern GA and across the
Appalacians will cross the forecast area today. Dewpoints will be
slow to drop this morning but will quickly drop off around mid-
day as drier air moves in. The deep mixing and drier air may cause
RH values to drop to around 20 degrees this afternoon at the spot
location. The wind shift to the NW/NNW will occur later this
afternoon. Throughout the day, winds will be around 10 to 15 mph
with gusts around 25 mph. Fog will not occur tonight with dry air
in place.
