-- Changed Discussion --
(Today through Sunday) Issued at 346 AM EDT SAT OCT 1 2016 Upper low continues to slowly propagate north, now located just about directly over Cincinnati. This will keep isolated shower chances confined to the Bluegrass region down toward Lake Cumberland as upper forcing continues to depart off toward the lower Great Lakes today. Thunder chances still looking anemic with surface-based instability of perhaps a couple hundred J/kg complete with a stout temperature inversion near 700 mb. Increasing heights/thicknesses and warmer air advecting in on southwesterly flow will be somewhat offset by increasing cloud cover rotating into the region this morning and afternoon, keeping high temperatures in the mid 60s to low 70s. Weak surface ridging will build north tonight across southeastern Kentucky, allowing for another appreciable ridge/valley split as valley temperatures dip into the upper 40s with ridgetops remaining in the low-mid 50s. Shower chances will continue as energy skirts around the southern flank of the upper low riding through the southern Great Lakes. Valley fog will also be in the offing, especially across southeastern Kentucky where quicker clearing will take place. Sunday will offer up one final day of isolated showers, mainly north of Hal Rogers Parkway/Highway 80 in closer vicinity to any impulses which may clip eastern Kentucky. Cloud cover will slowly diminish from south to north through the day with warmer air once again kicking in aloft, allowing for high temperatures to reach normal values in the low-mid 70s. .LONG TERM...(Sunday night through Friday) Issued at 357 AM EDT SAT OCT 1 2016 The Long Term Discussion will be issued shortly.

&& .AVIATION...(For the 06Z TAFS through 06Z Saturday night) ISSUED AT 148 AM EDT SAT OCT 1 2016 An upper level low continues to meander across the Lower Ohio Valley. This will lead to bands of clouds through the period and the threat of isolated showers, moreso at SYM. Patchy valley fog will continue to develop as clearing has been robust early on, but will see clouds fill in through the morning from the west. This should inhibit much in the way of dense fog development as stratus and associated ceilings may become more of a concern. MVFR visibilities/ceilings continue to look probable through the night for most sites, with VFR conditions returning by mid Saturday morning. Showers look to dissipate before reaching SYM at this time, but will continue to monitor for additional development. Southwest winds will increase to near 5-10 knots this morning before diminishing this evening. && .JKL WATCHES/WARNINGS/ADVISORIES...
