826 FXUS61 KILN 082306 AFDILN Area Forecast Discussion National Weather Service Wilmington OH 706 PM EDT Fri Aug 8 2025 .SYNOPSIS... A broad area of high pressure dominates the region, leading to quiet conditions as we head into the weekend. Temperatures continue to warm, with daytime highs reaching the upper eighties. && .NEAR TERM /THROUGH SATURDAY/... Surface high pressure over the East Coast continues to drive our weather. Quiet conditions will be in place overnight, with overnight lows falling to the mid to upper 60s. Once again, river valley fog is possible where moisture sources are more abundant. && .SHORT TERM /SATURDAY NIGHT/... Much of the Midwest continues to be dominated by broad ridging and high pressure. As such, the forecast remains quiet. An isolated summertime pop up thunderstorm is possible, though probabilities remain low. Temperatures continue to slowly increase, with daytime highs reaching the upper 80s to low 90s. Overnight lows fall to the upper 60s/low 70s with patchy river valley fog possible. && .LONG TERM /SUNDAY THROUGH FRIDAY/... Mid-level ridging will persist Sunday into Monday. By Tuesday, the ridge could be flattened a bit by troughing moving across the northern tier of states. Additionally, guidance is in some agreement that a swath of deeper moisture will move into the Ohio Valley by Tuesday into Wednesday ahead of the weak troughing. The end result is an extended forecast with above normal temperatures trending a bit lower toward the end of the period with the best diurnal convection chances aligning with the deeper moisture. As far as hazards, locally heavy rain can`t be ruled out for Tuesday and Wednesday in areas that get the most persistent of diurnal thunderstorm activity. Apparent temperatures will routinely reach into the 90s each afternoon. && .AVIATION /00Z SATURDAY THROUGH WEDNESDAY/... VFR conditions are forecast through the taf period, with the only exception being at KLUK due to river valley fog. Kept in IFR vsbys but introduced a TEMPO LIFR based on persistence forecasting. Cu field dissolves this evening and winds lighten to around 5kts or less overnight from the southeast. Similar conditions expected on Saturday with VFR cu possible and winds slightly increasing during the daytime, generally remaining between 5-10 kts.
