I am right in the path of this thing and we had a similar storm around this same time last year.

Some were without power for three weeks, we had to go out of state to get gas and ice, it was bad. The red cross even made an appearance. The damage was extensive.

It was NO joke.

We ran from that storm in the car, so I'm obviously extra anxious this time around.

We feel more prepared this time.

To all who will potentially be affected, go get some gas and groceries, get your coolers ready, and find somewhere safe to go ASAP if you don't have proper shelter, and stay safe!

Hey there sweety, just chiming in. Yea I was in that one too, central ohio. We were without power for a week, so I hooked my car up to the house via power inverter - buy one lol. What was crazy is it brought the neighborhood together, something you dont see too much these days. Stock up on candles and liqour!

Thanks for making this thread... I was gonna due it as I'm on the Southside of Chicago and I'm getting ready to race home from work at 5....

Note: You couldn't tell by looking outside that this storm was coming... It's sunny and beautiful... Minus the occasional sun sprinkle...

Just wanted to say; anyone in the Severe Area~ Please stay safe! Please be careful! And God Speed~

This is sulaw signing out~

Chicago here too... just brought my seedlings in, since I already had one crop blow away in the high winds a few weeks ago

I'll try to capture any wicked storm activity if it comes this way! Careful people. Currently a tornado warning for the Sandwich, IL area...

Milwaukee area checking in. I have a feeling we are going to get some strong storms today you can feel it in the air.


Hopefully my seedlings do not get blown away.

:up

Also I really good radar sight is storm chaser-storm tracker sight. It shows all of the current storm chasers with cam feeds. The best radar I have found yet.

Chasers Live Link

The Chasers are in the area, many to chose from

Watching Shawn Brown and he has reported a rotating Wall Cloud and is west of Yorkville Illinois (correction), very windy and raining there. Things could have changed by the time this is posted, not sure how delayed the video is. The video keeps freezing so you have to keep trying to get a feed.

Thanks for posting a link that is the sight I love.

Chicago suburbs here. Last year was bad. Branches down everywhere,no power for three days and it looked like someone shot my A/C unit with a shotgun from the hail coming in sideways. Not looking forward to this again. Stay safe.

Shabona Illinois is reporting tree limbs and power lines down (a lot) and Sandwich Illinois is reporting 65 mph winds and 1" hail is reported SE of Sublette, not sure if these are right or not?.

on Chaser TV Live click on any icons that pop up on the map for details

Lots of info coming in where the icons are, too many to list, reports of rope tornadoes being obscured by rain by a trained spotter NW of Hampton in Franklin County, Iowa?

Tornado warning siren triggered and then ended as the thunder started in the Joliet area. Now experiencing heavy rain.

I'm not wishing for a tornado or any harm to people, But wind and hail is good for business to me.

You must be in reconstruction, roofing or flood damage repair trades.

That is correct. I kinda live by the weather.

I'm in Central Illinois. Looks like I better get the generator gassed up and ready to go. Might as well go ahead and get the coffee pot set up too. It may be a loooong night.

this is definitely a nasty storm system, folks. where i live in the detroit area has been at a 5% tornado risk, since this morning....don't let that fool you.....i've seen tornadoes pop up in lesser risk areas. if anyone is in the path of any of these storms, keep a close eye to the sky, and hope you can hear the sirens blasting if something does hit your area. as a trained spotter, 2 good programs to invest in are Interwarn and GRLevel3. Interwarn basically gives you direct info from the NWS....including warnings, severe weather outlooks, and a lot more. GRLevel3 is a great radar program.....i invested in both a year ago, and have no regrets.

BULLETIN - EAS ACTIVATION REQUESTED TORNADO WARNING NATIONAL WEATHER SERVICE PITTSBURGH PA 918 PM EDT WED JUN 12 2013

THE NATIONAL WEATHER SERVICE IN PITTSBURGH HAS ISSUED A * TORNADO WARNING FOR...

CENTRAL GUERNSEY COUNTY IN EAST CENTRAL OHIO...
NORTHEASTERN NOBLE COUNTY IN EAST CENTRAL OHIO...
* UNTIL 945 PM EDT * AT 917 PM EDT...

A SEVERE THUNDERSTORM CAPABLE OF PRODUCING A TORNADO WAS NEAR SALT FORK STATE PARK...AND WAS MOVING SOUTHEAST AT 30 MPH.

* LOCATIONS IMPACTED INCLUDE... SALT FORK STATE PARK...
OLD WASHINGTON... SENECAVILLE... SENECA LAKE PARK... QUAKER CITY...

PRECAUTIONARY/PREPAREDNESS ACTIONS...

MOVE TO A BASEMENT OR AN INTERIOR ROOM ON THE LOWEST FLOOR OF A STURDY BUILDING. AVOID WINDOWS. IN ADDITION...HAIL GREATER THAN 1.00 INCH IS POSSIBLE.

It's definitely a strong system; several clusters of storms are capable of producing a tornado.

Being a derecho , - it's bound to move quickly.

As of right now, tomorrow is expected to be more of the same thing.
The first line of severe thunderstorms could even reach some parts of the East coast later on tonight.
Though the primary threat will be tomorrow afternoon.

The storm is on an SE trajectory.
Areas currently in the threat zone for tomorrow include New Jersey, and everywhere south.

As mentioned, not only are these storms dangerous -
But the entire system consists of several intense clusters,
some areas probably seeing one right after an other.

I'll be paying attention to the updates.

S&F.

We had a reported touchdown in Somonauk, but the damage appears to be limited to shorn trees and wind blown debris. The golf ball sized hail is what finally convinced me to grab the dog and go hang out in the basement for awhile.

As far as storms go, there wasn't substantial damage. I think the reason for the hype is the sheer number of people that could potentially be affected. Southern DeKalb County is rural by anyone's description, but they had these storms tracking through Chicago to Pittsburgh. Some great pics showing up on NSABook though.

Grew up in Shabbona, currently live in Somonauk, and it's a bit surreal to see the old stomping grounds mentioned on ATS!

I just checked the radar and there's a well-defined squall line moving through Pennsylvania, Maryland, West Virginia and Virginia right now.
