Discussion... 


A shallow layer of low level moisture continues across the 
forecast areas with a strong inversion around 760-800 mb. The NAM 
seems to be handling the current situation with cloud cover the 
best and model soundings indicate that most of the area will 
remain cloudy through sunrise. Due to this, the major update to 
the ongoing forecast was to increase the cloud cover across the 
forecast area. There are a few areas in SW NC and SW Virginia where 
clouds have begun to clear and temperatures have dropped rather 
quickly due to radiational cooling. For the update, had to adjust 
the lows downward in these areas into the mid 20s. Otherwise, the 
ongoing forecast was in good shape. Do not anticipate fog 
formation overnight with low-level winds remaining around 5-7 kts 
or so.
