Discussion:
We`re going to sound like a broken record for the next several
discussions with no significant weather expected for the rest of the
week and the upcoming weekend... which is typical as we creep
towards fall in the southern Appalachians. Temperatures will start
to eek back into the 80`s for most locations over the next couple of
days, and continue to steadily warm each day this week until we`re
right around, or just a tad above seasonal normals as we head into
the upcoming weekend. One difference from the last time we were this
warm is that the dew points will likely be in the low 60`s to upper
50`s instead of around 70, so it should feel less muggy than last
round of multiple mid 80 degree days.

The main aviation concern will be patchy fog expected around TRI.
Currently, the expectation is for something similar to last night
where visibilities stay VFR but with patchy fog in the area.
Otherwise, mostly clear skies and light northeasterly winds will
prevail after sunrise.
