No major changes to the forecast for this morning update. Tweaked
PoP chances to account for showers developing along the Cumberland
Plateau...But overall forecast remains on track and the forecast
discussion from this morning is still relevant.

.AVIATION...
18Z TAF DISCUSSION.

Isolated showers and thunderstorms present this afternoon across
the eastern Tennessee Valley. Expect the coverage to increase for
the first 3-5 hours of this TAF cycle, but then they should begin
to decrease in coverage once the sun starts setting. Confidence on
timing of storms is somewhat low due to the isolated nature of the
convection. Depending on where/when rain occurs at an airport we
could see fog develop tomorrow morning, but have not mentioned it
in the TAFs at this time and will wait until we see where rain
occurs this afternoon before being more confident in fog chances
tomorrow morning.
