.DISCUSSION...

It was a very nice, clear evening across Mid TN with high pressure
overhead. No major changes were made to the forecast. Patchy fog
was added for the Plateau, but south winds around 5 mph should
keep most areas west of the Plateau from forming dense fog. Still,
a few patches of shallow ground fog can be expected since
the ground remains moist from recent rainfall. Lows tonight will
be in the lower to mid 50s.

00Z TAF DISCUSSION.

Surface pressure gradient will start to slowly tighten over
western Middle Tennessee by late tonight, and tighten further over
all of the Mid-State by Wednesday afternoon. This will occur in
advance of a cold front, that is expected to be near the
Mississippi River by the end of the forecast period.

Decoupling of surface winds tonight will be most likely over
eastern areas, where a period of IFR conditions, due to fog, is
expected at CSV (between 09z and 13z). After 13z, south winds will
become gusty, with afternoon gusts of 15kt to 22kt becoming
common.

Clouds during the forecast period will be confined to patchy
cirrus.
