You're implying that today will be a dud, when everything is going as planned. You do realize the main event wasn't supposed to start in the morning, correct?

[Money]

Things are going as plan. Likely severe outbreak in E. IA/N. IL with a good possibility of someone seeing a tornado in that area.

[Tom]

Need to skies to clear up to destabilize the atmosphere.  Satellite imagery showing some clearing in E IA/W IL

Heavy rain, lots of lighting with the storm moving through DeKalb county at the moment

[Seahawkfan]

Line of storm's from south/central iowa stretching central Missouri heading east.

[Seahawkfan]

We have warmed up to 76 with the on off sunbreaks.

[Geos]

Atmosphere is more stable up in WI. Storms seems to be firing right along the warm front. That cell in Winnebago County is the one to watch in N IL.

[Hawkeye]

After a near complete bust of a week, a last minute skinny line of storms trained over my side of Cedar Rapids and dropped three rounds of hail.  Most of it was pea size, but one round had a few pieces up to 0.50" diameter and one round had 0.75" diameter pieces.

[Geos]

The line that's back along the cold front is the best bet to get severe weather this far north. Winds turned back out of the NE here and is killing activity as it approaches the lake. 

[Jaycee]

Isn't there someone from Clinton IL/IA on here?? looks like that tornado warned storm is headed directly towards that area as we speak.

[Maxim]

Strange. Did the warm front drift a bit south? That really makes no sense...

T-storm outflow did that. Fog has overspread the area again. Too much convection today up this way to allow for any destabilization.

Serious situation near Rochelle ---

 

This is confirmed TOG.

Live on the Weather Channel right now. 

This thing is a monster!

[Maxim]

Probably close to a mile wide by now. I'm pretty sure the velocity has maxed out on this thing too.

[Geos]

Tornado warning now out up by Harvard, IL.

 

Lake breeze/outflow boundary cuts across eastern McHenry county into southern Lake County currently. That might be the only thing that stops this supercell. Watch out if winds turn back southerly ahead of it. - Especially if your in northern Kane and southern McHenry County.

The cell itself is above that outflow boundary, I "think".

[Maxim]

Awful amount of damage already being reported from the tornado.

[Geos]

If it stays intact up to the Northwest tollway, it will be getting into a more populated area...

[Geos]

Wow, look at this video!
Crazy.

Still holding onto the cooler air up this way.

Marengo and possibly just south of Woodstock should really watch out now.


Steve KahnA MINUTE AGO

Large and dangerous tornado just east of Belvidere moving northeast at 40 at 7:33pm
TAKE COVER IF YOU ARE IN THE PATH OF THIS STORM

 

[Maxim]

That had to be an EF4 at least. Some homes were wiped clean off their foundation.

[Geos]

TOG still northwest of Marengo heading towards Woodstock!

 

Tornado Warning McHenry County until 8:30 pm

Confirmed tornado northwest of Marengo moving northeast at 45 mph.

 

TAKE COVER IF YOU ARE IN THE PATH OF THIS STORM

[Geos]

Heading north of Woodstock. Wonder Lake and northeastern McHenry County in line.

 

Beyond that this storm will be moving into much cooler air. 

 

Tornado near Wonder Lake and Greenwood moving northeast at 40 mph.

[Geos]

Crystal Lake area posters better watch this cell.

 

[james1976]

Crazy video. That circulation is impressive.

[Geos]

Storm rolled in with C-G lightning and winds gusted up near 40mph. Cut the power for a minutes and now it's pouring down hail here.

Not much bigger than pea sized though.

 

Impressive photos coming in.

So, I'm guessing the person who said this was a bust and people were just going to get a few showers was a little bit off..

[Geos]

It was slow in the afternoon, but it sure ramped up quickly.

 

Getting trained now by heavy downpours. Might break the 3" mark today.

 

Clearing out now...

 

Fairdale or what's left of it. 1 fatality confirmed.
