KEY MESSAGE 1) Some weak mid level energy will rotate through the upper level low situated over the Great Lakes through this afternoon. While temperatures will be seasonably cool with afternoon highs in the 70s, some cold air aloft will allow for some weak destabilization through the afternoon. MLCapes in the 1000-1500 J/KG will likely be enough to produce isolated shower and thunderstorm development, with the best coverage expected along and north of the I-70 corridor, closer to the upper low. && .AVIATION /09Z SUNDAY THROUGH THURSDAY/... Some patchy river valley fog will lift through mid morning with sct VFR cu developing later this morning and into this afternoon. A weak upper level disturbance moving through the Great Lakes will lead to isolated showers and thunderstorms this afternoon. The best chance for these will be along and north of the I-70 corridor. However, chances appear low enough at this point to leave any mention out of the TAFs. Any lingering pcpn will taper off this evening, leaving mostly clear skies overnight. Some river valley fog will be possible again late tonight, mainly affecting KLUK. OUTLOOK...No significant weather expected. && .ILN WATCHES/WARNINGS/ADVISORIES... OH...None. KY...None.
