-- Changed Discussion --
As of 130 PM Saturday... Minor flooding continues across parts of SE Ohio and NE Kentucky, however in most areas water is receding and flooding issues should continue to dwindle. A broad upper level trough moving through the western Great Lakes will provide mild and mainly dry weather this weekend. Models do show a couple weak 500mb ripples moving through tonight and Sunday. Kept POPs dry, but did include some additional clouds. High and low temperatures will run generally 5-7 degrees cooler than normal for late June.

&& .SHORT TERM /SUNDAY NIGHT THROUGH TUESDAY NIGHT/... As of 445 AM Saturday... Reinforcing shots of progressively cooler air arrive this period, on a series upper level short wave troughs that act to deepen the long wave trough position over the eastern U.S. The final short wave may finally be able to summon enough moisture for a shower or thunderstorm north come Tuesday. Canadian high pressure builds in for the the nadir of this cool spell is reached under clear, calm conditions Wednesday morning. && .LONG TERM /WEDNESDAY THROUGH FRIDAY/... As of 445 AM Saturday... This period begins with an increase in temperature and moisture, as an upper level long wave trough over the eastern U.S., moves off to the east. With the upper level high over the southwestern U.S. backing away, the upper level flow flattens. Increasing moisture in a return low level south to southwest flow around the surface high exiting to the east, and weak upper level short wave troughs in the flattening flow, will increase the chance for mainly afternoon and evening showers and thunderstorms Thursday and especially Friday. A stronger upper level short wave trough and surface frontal system will bring a better chance for less diurnally driven showers and thunderstorms next Saturday. Central guidance temperatures accepted, which show warming and then leveling off above normal, especially at night. && .AVIATION /17Z SATURDAY THROUGH WEDNESDAY/... As of 125 PM Saturday... VFR cumulus field in place this afternoon should dissipate some as the sun set. A couple 500mb ripples could bring some clouds tonight and Sunday, but rainfall is not expected. Depending on clouds, we could see some river valley fog early Sunday morning as temperatures drop into the mid to upper 50s in many areas. Opted to include some MVFR fog at EKN, but confidence not real high at this point. Wind will generally be light out of the west. FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 18Z SUNDAY...
