(Today through Wednesday) Issued at 330 AM EDT TUE AUG 23 2016 Mid level dry air continues to push southward into Eastern Kentucky this morning, per latest WV imagery. This dry air has prevented fog development across the northern counties early this morning, with some dense fog present in the southern counties mainly near bodies of water. There is still potential more fog could develop close to dawn as temperatures near the cross-over temperatures. However, it won`t be nearly as widespread as the previous day. Any fog should being to lift around dawn and dissipate by 13Z. Surface high pressure will gradually slide off to the east later today but not before we have another beautiful summer day with lower humidities. As the high departs, southerly flow will set up and begin ushering in warmer and more humid air. This additional moisture will allow for some fog development tonight, mainly in the valleys and near bodies of water. A weak upper level shortwave will then cross through the forecast area Wednesday afternoon and interact with the unstable airmass. This interaction should be enough to spark isolated showers or thunderstorms during the afternoon and evening hours, even with mid and upper level ridging holding steady over the southeastern CONUS. The shortwave, and any shower activity, should exit the region by Wednesday night. .LONG TERM...(Wednesday night through Monday) Issued at 330 AM EDT TUE AUG 23 2016 The long term discussion will be issued shortly.

&& .AVIATION...(For the 06Z TAFS through 06Z Tuesday night) ISSUED AT 148 AM EDT TUE AUG 23 2016 VFR conditions expected through the period. The exception to this will be the deeper valley locations where fog will develop again this morning. With drier air settling down across the region do not expect the fog to be as prevalent as it was yesterday morning except in the river valleys. Consequently, KSME, KLOZ, KSJS, and KSYM visibilities will likely be affected for a few hours through the pre-dawn hours this morning and as such went with a short period of MVFR VSBYS, 08-12Z. Did also allow for a tempo of denser fog affecting KSME for a time pre-dawn. Winds will generally be light and variable through the period thanks to high pressure in place. && .JKL Watches/Warnings/Advisories...
