000 FXUS61 KILN 292304 AFDILN Area Forecast Discussion National Weather Service Wilmington OH 704 PM EDT MON AUG 29 2016 .SYNOPSIS... Weak surface high pressure will work into the area for the day on Tuesday. A cold front will approach and move through the region Tuesday night into Wednesday. && .NEAR TERM /UNTIL 6 AM TUESDAY MORNING/... Isolated to scattered convection will be in place across generally south of Interstate 70 through early this evening. Thunderstorms are expected to dissipate with the loss of daytime heating. Dry conditions can be expected for the overnight hours. With the decrease in cloud cover and light winds overnight expect river valley fog to develop overnight. Added in patchy valley fog overnight. Elsewhere patchy fog will be possible, however do not think that visibilities will be low enough to include in the forecast at this time. && .SHORT TERM /6 AM TUESDAY MORNING THROUGH WEDNESDAY NIGHT/... Weak flow will be present across the area on Tuesday. Went with dry conditions for the day on Tuesday. Some of the models are trying to hint at some light activity working into northwest portions of the forecast area. Believe this is overdone and that drier air will keep any activity from developing. Bring precipitation chances into the region late Tuesday night into Wednesday as a frontal boundary approaches and moves through. Some residual activity will linger into the evening hours with the upper level disturbance. Dry conditions are expected by the end of the short term period. In addition cooler temperatures will work into the region Wednesday night with some locations across the north dropping down into the 50s overnight Wednesday night. && .LONG TERM /THURSDAY THROUGH MONDAY/... Upper trough across the eastern part of the continent at the beginning of the period will translate east by the end of the week. This will allow an upper ridge to build in over the weekend and continue into early next week. At the surface...high pressure will prevail through the period with a dry air mass in place. Temperatures will be below normal late in the week and then warm through the weekend and into Monday. && .AVIATION /00Z TUESDAY THROUGH SATURDAY/...

Just a few showers are lingering southwest of KCVG/KLUK but these are pushing southwest and will not affect those sites. Otherwise, with the loss of daytime heating, remaining cu field will continue to dissipate through mid evening with mainly just some high level cloudiness expected overnight. With light winds, expect to see some patchy MVFR to locally IFR fog development later tonight, mainly at KLUK and possibly KCVG/KILN. A dry airmass will be in place through the day on Tuesday, resulting in VFR conditions through the remainder of the TAF period. OUTLOOK...Thunderstorms are possible on Wednesday.
