000 FXUS63 KJKL 200713 AFDJKL AREA FORECAST DISCUSSION National Weather Service Jackson KY 313 AM EDT Sun Aug 20 2017 .SHORT TERM...
-- Changed Discussion --
(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.
