AREA FORECAST DISCUSSION
National Weather Service Jackson KY
313 AM EDT Sun Aug 20 2017

.SHORT TERM...(Today through Monday)
Issued at 313 AM EDT SUN AUG 20 2017

The latest surface map features a weak quasi-stationary frontal
boundary located just north of the Ohio River, amidst high
pressure generally sprawled from the eastern Ohio Valley down
through the southern Appalachians. Aloft, a short wave trough is
pulling away across New England, with rising heights across the
lower and mid-Mississippi Valley.

Warming temperatures and mostly clear skies will be on tap across
eastern Kentucky through the short term, as an upper level
ridge builds in across the southeastern CONUS. Highs will average
in the upper 80s today, with lows in the mid to upper 60s tonight.
Expect some diurnally driven cumulus, but little in the way of
upper level clouds. For Monday, some thin cirrus will be
advecting in from the northwest during the day, and there will also
be a touch more afternoon cumulus, given the slight uptick in low
level moisture. Overall, this should not impede a good viewing of
the eclipse. Highs will be in the upper 80s once again, with a few
to several degree drop in temperatures during the peak of the
eclipse.

.LONG TERM...(Monday night through Saturday)
Issued at 315 AM EDT SUN AUG 20 2017

The long term forecast discussion will follow shortly.

5k feet agl seen during the day. Winds will average less than 5
kts through the period.
