Crews are mainly focused on making sure people stay safe and are trying to clear roadways as quickly as possible.

The Sheriff is asking everyone to stay off the roadways in Montgomery County.

2 NEWS Reporter Adam Rife is on I-75 in the Northridge area, where I-75 southbound is completely blocked off. Traffic is being rerouted down to Wagner Road from the southbound lanes.

A tow truck is working to clear disabled vehicles from the area. The process is slow going, as the cars have to be moved one at a time.

Snow plows are out at the scene helping to push cars out of the way.

Definitely prayers for those who live in Dayton and the Miami Valley.

I used to live in Cincinnati --- this event reminds me a bit of one from the evening of Tuesday June 3rd, 2008.  F0 and F1 twisters that evening (I distinctly remember one of them hitting Oxford) so likely not as strong as tonight.   They could have been significantly worse, but a severe event earlier in the day had left a narrow stable layer of air near the ground. 

But Supercells just to the north of a warm front, that stayed discrete for a considerable period of time and kept on producing, even after dark..  A pattern to look out for.

Yeah I'm listening. This reminds of "Night of the Twisters". (For those old enough to remember the 1996 TV movie) 

Yeah...had to quit listening...it was not good at all. Seems low confirmed injury reports so far if any good news, but still very early.

I was out in the field today focusing on the storm I was on. I don’t know how much lead time they got, but that region is supportive of basements and most people have them. Hopefully cell phone alarms got people downstairs or to interior areas

Am I right in my impression that this level of activity wasn't anticipated? It was only an ENH day, right? 

Might have an argument that it overperformed.  Tempting to think it but I'm not sure yet.  Will be curious to see what the final count is.  

Everybody needs to remember that  really bad tornadoes can still occur with lower risk categories.

Seems odd since the radar indication is quite strong. It’s kind of in a radar hole, but the velocity couplet is impressive.

Not to mention, the observational data didn’t really support this either. It appears the warm front moved north and the storms were able to latch onto the very favorable orientation of the front. 

The problem we’ve had the past ten days is everything that’s influenced these set-ups has been on the micro level. If we had much more extensive real time data, like soundings closer to ongoing storms, we might have been able to detect those factors sooner. If this isn’t a cry for greater investment, I don’t know what is.

If I recall, the weather the day of the Xenia '74 twister was unstable, but never did they expect the extent of tornadoes that struck the area.

Don't really chase anymore since taking care of a sick loved one for several years now but family reunion today, relatives from out of town visiting. Nephews from Virginia always wanted to go with me back in the day but they were too young but now college aged and were thrilled to see this tornado with their uncle.  Ten mile drive to a few miles NW of Marion, IN to this one around 815pm . Thoughts and prayers to those affected by damage tonight...

Just noticed there was 4" diameter hail reported west of LAF.  Not sure it was that cell or another one but in any case, 4" hail is not that common in Indiana.

That can't be too far off the state record. I believe the record for Indiana is 4.25 or 4.50"

Was busy/traveling/otherwise not paying a ton of attention this weekend.  Will be interesting to dive into what happened more.  Pulled off the highway for nearly an hour and watched in disbelief on radar as the first tornado went through Dayton. 

My impression was earlier in the afternoon that there was tornado potential near the warm front in Ohio, but that activity likely would grow upscale before getting there and mute the potential.  Seems like it stayed discrete longer than expected, and perhaps instability overperformed a bit?  If you take the 0z ILN sounding's instability and put it on top of the radar detected wind profile closer to 2-3z it's a really prolific environment.  For reasons many others have mentioned, this really was not a good outcome and hoping the death toll is zero or something close to it.

This is roughly what the 00z ILN balloon hodograph looked like superimposed on the VAD hodograph. You can really see how much the 0-3 km wind vectors increased in magnitude. Very little direction change, but magnitudes just about doubled. When you see the phrase enlarged hodographs, this is what it means.

The ~ 20kft TDS and Vr just below 100 knots puts this right in the space between EF3/4. The few damage indicators I've seen (like the high tension tower) are solid EF3 degrees of damage.

The eastern end of the outlook definitely overperformed. I would say IN was about as expected, but the OH forecast was a positive bust. And this isn't a shot at SPC either, there was very little to indicate an increased risk until it was happening. CAMs were not on it, and when they were they were too far north, even as late as 20z.

Yeah when that jet ramped up it basically caused the storms to have no outflow. Those southern most cells were absolutely ingesting clean warm air with helicities at 4-500.

As I said earlier as a former Toledoan reminded me so much of June 5-6 2010. Discrete cells with a strengthening low on a warm, muggy night. That big one from Dayton stayed tornadic until 3 AM
