The episode as NWS CLE wrote it up.

NWS Cleveland, OH wrote its last area forecast discussion before the first event at Jun 13, 12:20 PM EST, 1 hour 35 minutes earlier.
Area Forecast Discussion National Weather Service Cleveland OH 120 PM EDT Tue Jun 13 2017 .SYNOPSIS... A weak cold front will drop south into the area today and stall for Wednesday then slowly lift back north of the area Thursday into Friday. A cold front will push east through the region Sunday. && .NEAR TERM /THROUGH TONIGHT/... No major changes from previous update. Scattered convection has developed across the area, and adjusted pops to the latest radar and hi-res trends. Switched to coverage wording for the forecast through the evening, back to slight chance after Midnight. Temps have shot up rapidly this afternoon, even behind the outflow boundary with winds off of the lake, so adjusted the temperature trends a bit. Still expecting a rapid diminishment of convection after the 02-04Z timeframe, and will look to refine pops a bit more before the next forecast update. Previous discussion... Fairly significant changes to the forecast today and tonight as new data coming in shows frontal boundary pushing well through the area this afternoon/evening and likely settling south of the area tomorrow morning. This has resulted in a lowering of pops overnight, cutting to slight chance south and southwest, with sub-mentionable pops north and northeast. Growing more and more confident in this scenario, as latest satellite and obs trends show a boundary already pushing onshore across far NE OH and NW PA. This is likely an outflow from the remnant central Great Lakes MCS that moved through overnight vs. the actual synoptic front. Much of today's forecast still remains on track, with the front progged to move south of the lake between 18Z and 21Z, but then pushing through the area entirely by the 02-03Z timeframe. Marginal risk still looks warranted with 2500-3500 j/kg SBCAPE building south of the front, however little/no deep layer shear, nearly saturated environment up through 700mb, very dry air above 700mb has the makings of a less-organized pulse- type storm environment with downburst wind potential the primary threat. Some minor adjustments to high temps today, especially across far NE OH and NW PA where winds have already flipped more NW/N off of the lake and forecast highs have been lowered. && .SHORT TERM /WEDNESDAY THROUGH FRIDAY NIGHT/... The front will be stalled over the cwa Wed then lift nne back out of the cwa Thu and Thu night which should leave only small chc pops for mainly the east on Fri. Overall, there is not a big flood threat but with a prolonged threat for tsra, if some spots see repeated heavy rains then some localized flood related issues could develop. The severe threat should stay limited. Temps should run near or slightly above normal Wed and Thu then trend a few degrees warmer for Fri as the warm front lifts off to the ne. && .LONG TERM /SATURDAY THROUGH MONDAY/... The first half of the long term forecast looks fairly active with the extended guidance showing an upper trough over the Great Lakes that will support an area of low pressure and its associated cold front at the surface. Given a favorable setup for convection with good upper level support, have raised pops to high chance pops for much of Saturday and Sunday until the cold front passes early Monday morning. Temperatures through this time period will be close to normal as the area will be in the warm sector of the cold front through the weekend. The first couple days of the next work week certainly will be a change of pace from the past two weeks or so. Cold air behind the cold front will move in with support from northwest flow aloft. A broad area of high pressure is progged to develop, keeping things rather dry for Monday and much of Tuesday. So while, these couples days will be dry, temperatures will take a tumble into the low to mid 70s, or a couple degrees below normal. && .AVIATION /18Z Tuesday THROUGH Sunday/... A cold front will sink south into the region this afternoon. Unstable conditions south of the front will lead to rapid cumulus development through the afternoon hours, with scattered TSRA possible. Coverage should be fairly widespread, but only mention TSRA in a TEMPO at KMFD and KCAK this afternoon, with VCTS mention at KFDY, KTOL and KYNG. TSRA activity should diminish rapidly after 00Z, with some localized MVFR BR developing overnight, especially where thunderstorms persist this afternoon. Winds will veer from southwesterly south of the front to northerly north of the front, becoming generally calm after Midnight. OUTLOOK...Non-VFR possible in thunderstorms through Thursday night. && .MARINE... The lake will start rather benign today as southerly flow continues over the basin. However, a weak cold front will shift south throughout the day today and winds will flip around from the south to the north and eventually to the northeast for Wednesday, once the front stalls south of the lake. Winds will pick up while northeast on Wednesday and for now look to be below SCA conditions, although waves may be close in the 2 to 4 feet range. The front will then move back north on Thursday as a warm front and winds will shift back around to the south for Thursday and should remain in a south to southwest flow through much of the weekend. These southerly winds should be much of the same that we have seen from the past couple days with 5-15 knots over the lake for much of the end of the week. && .CLE WATCHES/WARNINGS/ADVISORIES...
