(Tonight through Monday)

It was partly cloudy and dry across the Mid-State early this
afternoon, with 3 pm temperatures ranging from the lower 80s along
the Cumberland Plateau to the middle and upper 80s elsewhere.

Expect an 850mb ridge to build over the Ohio and Tennessee Valleys
and southeastern United States over the next three days, producing
dry conditions across the Mid-State through Monday. Temperatures
will be on the rise, with daytime highs reaching 90 to 93 degrees
most areas by "eclipse day," on Monday. The 5-degree drop in
temperatures during the period of eclipse, between 18z and 19z,
will provide only a brief relief, because once the sun pops back
out the temperature is forecast to soar back up pretty quickly.

Speaking of the upcoming big Total Eclipse, here are the
temperatures and percent sky cover forecast for Nashville between
18z and 20z on Monday:

18z...89 deg, 18% cloud cover
19z...84 deg, 18% cloud cover
20z...90 deg, 18% cloud cover

During the eclipse, clouds are forecast to consist mainly of
some scattered cumulus clouds and, perhaps, some scattered
cirrus...which should be about as optimum as possible for this
time of year. If Monday`s forecast continues on the same track its
been on for the last several days, many people in the Mid-State
should get a pretty doggone good view of this rare event. So, keep
your fingers crossed!


A cold front rolls in Tuesday through Wednesday, bringing in sweep
of showers and thunderstorms. However, by late next week, things
dry out again, with a drop in humidities and afternoon highs
mainly between 80 and 85 degrees next Wednesday through Friday.



VFR with some MVFR fog possible. Winds will be light and variable
overnight, with fog possibly developing at KCKV, KMQY, and KCSV
overnight into the early morning. KCSV may see IFR fog closer to
sunrise as well. Otherwise expecting VFR conditions with winds
becoming westerly around 5 knots during the day Saturday.
