191 FXUS61 KILN 100514 AFDILN Area Forecast Discussion National Weather Service Wilmington OH 114 AM EDT Tue Jun 10 2025 .SYNOPSIS... Surface high pressure will build in overnight and bring drier conditions and near normal temperatures through midweek. Warmer and more humid air returns to the region by the end of the week into the upcoming weekend. This return to a warmer and more humid pattern will bring renewed daily chances for showers and storms Friday through Sunday. && .NEAR TERM /UNTIL 6 AM THIS MORNING/... Isolated showers slowly pulling east and should exit the area by sunset. Clearing is working through the region at this time, especially along/west of I71. Another weaker shortwave rotating through the slowly departing mid level low over the lower Great Lakes will bring a mid level cloud deck and a slight chance for showers mainly in west central Ohio, mainly between 02-06z before drier air takes over. Temperatures tonight drop to lows in the lower and middle 50s, but upper 50s in the lingering low level moisture in south central Ohio/Northeast KY. && .SHORT TERM /6 AM THIS MORNING THROUGH 6 PM WEDNESDAY/... Stacked deep low pressure to translate east thru the Great Lakes overnight and into southern Canada Tuesday. Colder temperatures aloft firmly in the post frontal environment will lead to scattered to broken fair weather cumulus coverage Tuesday. The best coverage of clouds will occur across the north where the coldest temperatures aloft will exist. Highs on Tuesday will range from the lower/middle 70s north to the upper 70s south. As the low pulls away from the area into southern Canada the mid level flow will become northwesterly. Surface high pressure will build across the area Tuesday night. Diurnally driven cumulus clouds will give way to clearing early. Temperatures to drop to temperatures slightly below normal with lows ranging from the lower/middle 50s east to near 60 west. && .LONG TERM /WEDNESDAY NIGHT THROUGH MONDAY/... A surface high slowly drifts east of the Ohio Valley and weakens Wednesday through Thursday evening. Southwesterly flow northwest of the high leads to warming temperatures and increasing humidity during this timeframe. Forecast highs are in the lower 80s on Wednesday and middle 80s on Thursday. Lows are forecast to be in the lower to middle 60s. Rain chances return on Friday and into the weekend. Increasing instability each afternoon should provide fuel for storms especially along and south of I-70. A series of weak disturbances and boundary dropping in from the north may help spawn storms in the favorable thermodynamic environment. && .AVIATION /06Z TUESDAY THROUGH SATURDAY/... A narrow corridor of FEW/SCT VFR clouds near the slowly-advancing front will drift through the region through daybreak amidst otherwise clear skies. A subtle wind shift from SW to W will occur with the FROPA, which should occur for all the local sites by 12z, but winds should generally remain around 5kts or less through daybreak. Westerly winds of 10-12kts, with gusts 15-18kts, are expected by midday before subsiding once again past 00z. VFR Cu should sprout again by early afternoon, with SCT to BKN sky conditions expected for the afternoon. Have included some SCT/BKN high level clouds in the fcst due to the expectation for smoke aloft to once again be drifting through the region. There is not expected to be any cirrus, but the sky above the VFR Cu won`t be completely clear, either. The Cu/stratocu will slowly dissipate after sunset, yielding mostly clear skies once again late in the period. OUTLOOK...Storms will be possible Friday night through Saturday. && .ILN WATCHES/WARNINGS/ADVISORIES... OH...None. KY...None.
