000 FXUS63 KJKL 270705 AFDJKL AREA FORECAST DISCUSSION National Weather Service Jackson KY 305 AM EDT Thu Apr 27 2017 .SHORT TERM...(Today through Friday) Issued at 303 AM EDT THU APR 27 2017 An area of low pressure is lifting northeast into the great lakes this morning with a trailing cold front extending southward across Illinois into western Tennessee. A band of showers with a few embedded thunderstorms is working into central Kentucky presently, left over from the convection in the lower Mississippi river valley yesterday. This band is encountering very little, if any instability as it continues to press eastward. This activity will push across eastern Kentucky this morning. The risk for any severe storms is greatly diminishing as instability remains much too limited. While the showers should exit by midday, there likely will not be enough time to destabilize behind the departing showers, so the front will continue to press on through the area during the evening hours. As a surface ridge builds in tonight, we should see slightly cooler temperatures with a slight ridge to valley split. While ridge will slide eastward on Friday, we will remain dry as southerly flow begins to pick up. Models are likely over doing the moisture advection on Friday with a due south flow. This will likely keep dewpoints a bit lower than models anticipate and further keep rain chances at bay. .LONG TERM...(Friday night through Wednesday) Issued at 303 AM EDT THU APR 27 2017 Long term discussion to follow shortly. && .AVIATION...(For the 06Z TAFS through 06Z Thursday night) ISSUED AT 154 AM EDT THU APR 27 2017 Low level wind shear will continue just ahead of an approaching cold front overnight. As the front moves on through, a complex of showers and a few thunderstorms will push east across the area. In the wake of this activity and the front, we may see a brief period of MVFR cigs. These MVFR cigs will return to VFR this afternoon with VFR conditions remaining for the rest of the TAF forecast period. && .JKL WATCHES/WARNINGS/ADVISORIES...
