AREA FORECAST DISCUSSION...UPDATED
National Weather Service Morristown TN
128 AM EDT Tue Oct 20 2020

.UPDATE...
FOR 06Z AVIATION.

.DISCUSSION...

A quiet evening with just some patches of mostly high clouds around.
Current forecast for tonight generally looks reasonable.
Dew points are running a bit above current forecast, so will bump
those up a bit as well as tweaking some min temps up slightly.

.AVIATION...
06Z TAF DISCUSSION.

Dewpoint depressions were running around 2-3 degrees or less
throughout the TN valley as of 05z. Fog product satellite imagery
shows some fog starting to form. Given the setup, have added in
some fog to all terminals. The best chance for fog seems to be at
KTYS, so have added a TEMPO for 1SM BKN004 there. Otherwise, fog
will dissipate by 13z or so, for VFR categories through the day at
all sites. Fog seems unlikely towards the end of the 06z, but may
be something to watch for next issuance.
