DISCUSSION
KEY MESSAGE 1) Mid level energy will move out of the western US this weekend in zonal flow aloft and progress east across the Ohio Valley into early next week. As it does, a surface wave and/or inverted trough will shift east across the Tennessee and Ohio Valley region. This will allow for pcpn to overspread our region Sunday into Monday. Thermal profiles and any snow amounts will be dependent on the exact track of the system, but as of now, it looks like some accumulating snow will be possible along and north of the Ohio River. For now, will keep more of a rain/snow mix across our south.
AVIATION /18Z THURSDAY THROUGH TUESDAY/
Surface high pressure will settle into the area tonight into Friday. With light winds and some lingering ground moisture from earlier today, some patchy fog may develop at the southern TAF sites later tonight into early Friday. Confidence is not terribly high in this as not all models are hinting at this. Will therefore limit vsby restrictions to just a tempo group at KCVG/KLUK for now.
OUTLOOK...MVFR conditions are possible Saturday night. MVFR/IFR conditions are possible Sunday into Monday.
ILN WATCHES/WARNINGS/ADVISORIES
OH...None. KY...None. IN...None.
