06z taf discussion.
Bna/mqy/ckv/csv...cirrus clouds blanket middle Tennessee this
evening as high pressure retreats to the east and a cold front
approaches the mid state from the west. Expect early morning
radiation fog at mqy, much like this morning, as the dew point
spread is already down to 3f. Tomorrow winds will increase from
the south as the pressure gradient tightens up. However, showers
will be slow to develop given the dry antecedent air. Most
locations won't see any precipitation until the evening or
overnight. Ceilings will gradually deteriorate after 00z tomorrow
