906 FXUS61 KILN 300538 AFDILN AREA FORECAST DISCUSSION National Weather Service Wilmington OH 138 AM EDT Thu May 30 2024 .SYNOPSIS... Upper level disturbances will keep a chance of showers through this evening. High pressure will bring dry and cool conditions Thursday through Friday. An unsettled pattern is expected from late Saturday through early next week. && .NEAR TERM /UNTIL 6 AM THIS MORNING/... Isolated showers continue into the early overnight hours on the backside of an exiting low pressure system. Thunder potential will be much more limited now after sunset, but cannot be completely ruled out. Shower coverage will continue to wane overnight, with little to no coverage expected after midnight. Models show mid level clouds dissolving overnight. Combined with the light surface winds, this could result in patchy overland fog, with better fog potential along river valleys. Lows will be seasonably cool tonight, dipping into the 40s for most. && .SHORT TERM /6 AM THIS MORNING THROUGH 6 PM FRIDAY/... High pressure from Canada builds southward through the Great Lakes and Ohio Valley Thursday and Thursday night. High pressure should provide a decent deal of sunshine on Thursday, but the air mass is cool and below normal temperatures from the upper 60s to lower 70s are expected. At night, decent radiational cooling with clear skies and light winds will support lows in the mid to upper 40s. && .LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/... A series of disturbances and fronts will keep unsettled weather over ILN through most of the period. Departing high pressure should keep the weather dry Friday night. Moisture returning behind the high ahead of a short wave will bring the threat for showers and thunderstorms on Saturday and Sunday. There may be a brief dry interlude early Monday before the next short wave and a boundary arrive from the west with more thunderstorm chances for Monday afternoon through Tuesday. A more potent short wave and front colliding with an unstable airmass could bring additional thunderstorms on Wednesday. After a cool start Friday night with lows in the low 50s, temperatures are forecast to be near normal through Tuesday with highs in the upper 70s to low 80s, and lows in the low and mid 60s. Warm advection may boost readings above normal to the mid and upper 80s on Wednesday. && .AVIATION /06Z THURSDAY THROUGH MONDAY/...

Long wave mid level trof over the Eastern CONUS. Embedded shortwave shifting south and east of the area. A few lingering showers will continue to diminish as they track southeast for the next couple of hours before dissipating. Due to isold coverage and decreasing coverage have only have a VCSH mention in the TAFs. Mid level cloud deck will gradually erode tonight. This will lead to river valley fog, which will impact KLUK. Also, expect MVFR to IFR vsby restrictions at KILN. Vsby reductions will quickly improve shortly after sunrise with VFR conditions thru the remainder of the forecast. Some few to scattered cu development will be possible this afternoon. Winds remain below 10 kts through the period, shifting from the NW to NNE this morning. OUTLOOK...Thunderstorms will be possible late Saturday through Monday.
