It sounds like locally the most significant damage occurred in the southern Cleveland metro with the rear inflow jet/outflow surge south of the little MCV/bookend vortex that tracked just south of Cleveland.  A long corridor from extreme eastern Lorain County through northern Portage County/southern Geauga County that is a few miles or so wide saw severe winds, with widespread tree/powerline damage (including power poles snapping) and some sporadic structural damage (heard a few roofs off, siding off houses).  Based on velocity data and the damage I'm guessing a very large and fairly heavily populated area saw 60-80MPH gusts, with some local gusts possibly as strong as 100MPH.  Velocity peaked at around 90 knots for a few scans from what I saw at roughly 1000 feet above ground level...a couple of scans may have had a few higher pixels (I don't have the radar in front of me and am going off of what I observed at the time).  CLE may survey the area out of due diligence, but I really didn't see any evidence of anything tornadic in this area.  Other tornadoes will likely be confirmed in OH though and a few already have been. 

Yeah, that is possible. Google mapping it, I actually live 3.8 miles away from them. And my sister is on crutches, so she is going to be able to be blown over by lighter winds than a normal person.

A downburst?

Definitely.  Ignore the greens...that's velocity folding...that was all very strong wind blowing away from the radar.  There are a couple of areas of rotation in this image...one east of Norton, another NE of Norton and WSW of Akron (that one is more of convergence than true rotation, but is something to watch in these squall line setups with high shear), and another in southern Cuyahoga County near the Broadview Heights/Brecksville boarder on the NE edge of the downburst where there's a bit of inflow next the big rush of wind away from the radar.  While it doesn't take a ton of rotation to get a weak spin-up tornado in the environment we had, none of those areas of rotation were strong at all, and that huge area of strong outflow wind is going to easily do the most damage out of anything on that radar image.

Little historical note.  Since 1950 and including 2017, there have been 17 Novembers that have produced tornadoes in Indiana.  7 of those 17 have occurred since the year 2000.  Likewise for Ohio, there have been 11 Novembers that have produced tornadoes, with 5 occurring since the year 2000.  I didn't look at actual tornado counts since there is more likely to be some inflation there compared to earlier years.  

Some of this may be due to better detection/reporting, but the trend is not as noticeable or uniform across other months so there is something else.  Could be a short term thing that erodes over time, or perhaps November is becoming more favorable for tornadoes?

So apparently the "Celina tornado" is all 1 tornado.

Or maybe not. There might have been a separate EF2 as the end coordinates of the long tracker don't match up with the coordinates that ILN put out earlier.  Kinda confused now.

CLE's MIC recently Tweeted that they have a total of 5 confirmed tornadoes and that additional surveys are still ongoing, so there will be more.  In addition, he said there was an unofficial ob of a 105MPH wind gust in Aurora, OH (Portage County) with the big outflow surge south and southeast of CLE.

Well if you go by what I just saw on local news, they said three EF 2 tornadoes confirmed in Mercer county. One near Wabash in the southern part of the county, one near St. Anthony in the western part and another near Celina. But they also say the latter two were from the same storm. To me it sounds like it lifted at St Anthony and dropped again near Celina.

That 39 mile tornado track was the longest tornado track in IN since the Henryville tornado of March 2, 2012.

Was going to post that earlier.  If you want to get really technical, the 11/17/13 tornado that scraped the southeast side of LAF had a longer path entirely within Indiana (38 miles).

I have received some information about the Celina tornado from my brother (pics from his friend's dad)

Quote

My friend grew up in Celina, and his parents are safe. A tornado hit their town last night. His dad shared pictures on Facebook from the news down there.

Ben works for a company in Cleveland. But their facility in Celina was hit pretty hard. Those are cinder blocks on the front of that building that are missing.

The 125MPH macroburst in Ashtabula County is now an EF-2 with a 7 mile long path.  Up to 11 tornadoes in CLE's CWA. 

If you add what happened elsewhere in Ohio and Indiana, probably somewhere around 20 tornadoes.  Fwiw, the 11/10/2002 outbreak had 21 tornadoes in IN/OH.  And no F4 this time of course.

It's surprising how many tornadoes this one ended up producing, though a lot of the OH ones were squall line/QLCS type deals which as people in Indiana know can really rack up the tornado count quickly.  There were a handful of EF-2 tornadoes with this event, but only the one long tracked one and as you said nothing stronger than that, so this is still a notch or two below 11/10/02 (and well below 11/17/13), but still not bad.

11/17 is almost like a Fall super outbreak. There's never the same ceiling with outbreaks in Fall compared to Spring, but it is so far outside the bounds of what's been recorded at this time of year (over 70 tornadoes with over 30 of them EF2+, and basically all in this sub).

Agreed, that event was more on the once in 50 years level for the time of year it occurred.
