Severe threat 6/10-6/12

[mob1]

The cell just north of Waldo IL might be next to go if it can stave off any crap-vection. 

[frostfern]

I don’t know, but the SW corner of Michigan might still be in play for a couple tornadoes.  Higher dewpoints have finally surged north.  Maybe the dying crapvection boosted the moisture but 2000 j/kg should be enough if it maintains.

Giant tornado near Streator IL per Colin Davis. Environment near those two supercells in central IL is extreme, STP of 10, SCP of 40, 3000+ MLCAPE and 500+ ESRH.

Looked like a direct hit on Reading

That newer to cell to the south looks ready to drop the next big one

Gonna need a downstream watch soon, environment in Michigan the storms are gonna be entering is juiced

Confirmed tornado in northern Kenosha. Missed me by a few miles. Video here: https://x.com/kenoareaweather/status/2065212739945934931?s=46 (Not the actual tornado but just an early video put out)

Absolutely beautiful storm though

Mesoscale Discussion 1101
   NWS Storm Prediction Center Norman OK
   0638 PM CDT Thu Jun 11 2026

   Areas affected...Southwest Lower Michigan...central and northern
   Indiana...far western Ohio and eastern Illinois.

   Concerning...Severe potential...Watch needed soon 

   Valid 112338Z - 120115Z

   Probability of Watch Issuance...95 percent

   SUMMARY...A tornado watch will be issued within the hour east of
   tornado watch 313.

   DISCUSSION...Instability continues to increase across northern
   Indiana and into southern Michigan as the outflow boundary from
   earlier convection continues to modify/lift northward. South of this
   boundary, an environment similar to the 21Z ILX RAOB is present with
   near 4000 J/kg MLCAPE. Along and north of the boundary instability
   is more limited, but shear is very strong with 250 m2/s2 0-1 km SRH
   and strong low-level clockwise curvature per an 22Z RAOB launched by
   the Valparaiso University Meteorological Department in Valparaiso,
   Indiana. Along and south of this boundary, widespread damaging winds
   are likely along a squall line this evening. In addition, embedded
   QLCS tornadoes and occasional embedded supercell tornadoes will be
   possible through the evening given the presence of strong low-level
   shear.

   The last few runs of the HRRR hint at some pre-frontal convection
   ahead of the line across central/northern Indiana later this
   evening, likely in response to the strengthening low-level jet. It
   is uncertain whether this will occur, or have sufficient time to
   mature before being caught by the main squall line, but these storms
   could pose an additional supercell tornado threat later this
   evening.

GRR holding off as usual until the storm is overhead to issue any watches

Don’t even have a severe yet.  The fuel source is a bit elevated for tornadoes near 1-96, but we have a warm boundary layer this side of the lake, so the initial gusts could get crazy as the bow / comma pushes inland.  The bottom thee rows definitely need the tornado watch as that area has decent surface based instability.

[TheNiño]

Given how beautiful the Kenosha storm was there is a TON of pictures/videos coming in. I’m thinking the “public confirmed” tornado was actually a rotating wall cloud that never actually made it to the ground. But given the rotation a lot of people thought it was. 

[Toro99]

The tornado watch was issued about 9 minutes before the thunderstorm warning popped up on my TV, I’m sorry, but that’s ridiculous

Spc issues the watches not the local nws offices

Still of video from tornado near Reddick tonight. 
 

Other pic is Sup before going tornadic.

That is a major tornado in the middle of the Lake County burbs, that is not going to be good.

But you still got a warning, though.

Local NWS offices do not issue watches; that’s the SPC.

The CC drop is immense on it. Those traffic cams with the dark ominous blue hue reminds me of the joplin vid where that trucker drives into it, the sky goes from modest dark to total pitch black darkness.

MKE terminal doppler looked pretty telling for a brief tor, will try and get a framegrab

May be cycling near portage. Will see if it drops another down

Possible tornado moving onshore near Holland, MI

Tornado down heading for Schaumburg @SchaumburgStormer!

Current radar almost looks like a line of supercells with hooks moving in
