188 FXUS61 KCLE 101943 AFDCLE Area Forecast Discussion National Weather Service Cleveland OH 343 PM EDT Thu Jul 10 2025 .SYNOPSIS... A weak stationary front will linger over northern Ohio through tomorrow before lifting northward. A low pressure system will track through the Upper Great Lakes Saturday night and Sunday, dragging a cold front through the region. This front will stall near the Ohio Valley Monday before returning north through mid week. && .NEAR TERM /THROUGH FRIDAY NIGHT/... Scattered showers and thunderstorms have developed this afternoon mainly along and east of I-71 across northeast Ohio into northwest Pennsylvania. The afternoon convection developed along a weak stationary front and lake breeze from Lake Erie. Most of the thunderstorms will remain sub-severe but there could be an isolated stronger storm with downburst winds and some hail. The steering flow aloft is rather weak so these storms are moving or drifting slowly eastward. Locally heavy rainfall may be possible. Most of this afternoon convection will dissipate around sunset as we lose the daytime heating that is driven these storms. The flow aloft will be zonal tonight and Friday. A weak disturbance in the mid level flow will track across the Upper Ohio Valley and lower Great Lakes on Friday. This disturbance in the 500 mb flow will help lift the weak stalled frontal boundary northward on Friday. We will maintain some slight POPs Friday into Friday evening. The Day 2 SPC outlook has a marginal risk for a stronger storm possible over northwest Ohio which will be closer to the weak frontal boundary. Isolated damaging wind gusts would be the main threat with any stronger storm Friday. Most of the convection in our area will dissipate Friday evening by sunset. High temperatures tomorrow will range from the middle 80s to around 90 degrees. && .SHORT TERM /SATURDAY THROUGH SUNDAY NIGHT/... An upper level trough will swing through Upper Midwest into the Upper Great Lakes Saturday and Saturday night. A weak cold front will slowly drop down across the Great Lakes region late Saturday into Saturday night. Ahead of the cold front Saturday, high temperatures will warm into the upper 80s and lower 90s. Scattered showers and storms will be possible as this weak cold front sags into the Upper Ohio Valley Saturday night. The Day 3 SPC outlook has a marginal risk for severe weather and the main threat would be isolated damaging wind gusts possible. The weak cold front will slow down and stall out over the area on Sunday. Scattered to widespread showers and storms are expected mainly during the daytime heating Sunday. Slow movement of storms this weekend may cause heavy rainfall and an isolated flash flooding concern. Highs on Sunday will be generally in the mid 80s. && .LONG TERM /MONDAY THROUGH WEDNESDAY/... A weak frontal boundary will continue to be nearby or just southeast of the area on Monday. We will mention slight to chance POPs for diurnally driven convection for Monday. The weak stalled front will eventually wash out Monday night. An upper level ridge of high pressure will move from the Central Plains into the Ohio Valley Tuesday into Wednesday. Warmer and drier weather will be expected with this upper level ridge moving across the region. High temps will climb into the upper 80s and lower 90s with heat index values approaching the upper 90s to 100 degrees. The next chance for rainfall may arrive Wednesday night with a cold front advancing through the Great Lakes and Ohio Valley. && .AVIATION /18Z Thursday THROUGH Tuesday/... VFR across the TAF sites early this afternoon with non-VFR possible in scattered showers and thunderstorms through this afternoon. Current radar and satellite observations suggest CAK/YNG have the highest potential of seeing direct tsra impacts later this afternoon and evening, as the lake breeze is already passing through ERI/CLE. MFD will be on the fringe, thus kept vcts mention, though low confidence in direct impacts precludes tsra mention at this time. Otherwise, patches of dense fog may develop once again overnight, mainly impacting MFD/CAK/YNG where more widespread rain is more likely. Otherwise, will need to watch remnant nocturnal convection towards the west for possible Friday morning impacts at TOL. Winds are generally favoring a west to southwest direction ahead of the weak cold front/lake breeze, and favoring a north to northwest direction behind the cold front/lake breeze, around 5 to 10 knots. Winds will become light and variable overnight before favoring a southwest direction by late Friday morning, around 5 knots. Outlook...Non-VFR possible Saturday afternoon into Sunday in showers and thunderstorms. Mainly VFR expected Monday and Tuesday. && .MARINE... With the exception of thunderstorms, winds on Lake Erie are generally expected to be 10 knots or less through Friday. Winds may briefly increase to 10 to 15 knots and shift towards the west late Saturday into Sunday as a cold front moves across the lake. This could usher in some 2-footers across the central and eastern basin of Lake Erie Sunday afternoon and evening. There is a low chance of thunderstorms impacting the western and central basin of Lake Erie Friday afternoon and evening. Chances for thunderstorms increase by late Saturday into Sunday as a cold front moves east through the area. && .CLE WATCHES/WARNINGS/ADVISORIES... OH...None. PA...None.
