3. Great! The last storm here had golf ball size hail. I'm waiting for a replacement roof.

Hoping I don't see or feel any raindrops on my head indoors.

2. WOW

We went thru one in Northern Illinois 35+ years ago and I tell you it was a living hell

4. Well, picked a fine time to visit Macomb Il.

For the time since I was born there, 72 years ago.

Fortunately, the RV park where we're staying has a storm shelter.

6. Summer, 2012 derecho hit DMV, Mid Atlantic; high 90s

temps, sudden intense winds and all power out. On the 2nd or 3rd day we had gasoline and fled to the Delmarva coast.

7. I'm in the path, and will take cover in a central room away from windows.

I live just off I-355, 6300 south.

8. We battened down the outside elements

on our roof deck. If they were to go flying, it could kill someone.

More here:

The storm system is paired with humid conditions and a heat index of more than 100 degrees in the Chicago area. Borchardt said the heat and humidity will contribute to the intensity of Monday’s storms.

“You can almost wear the air,” Borchardt said. “This kind of air is like rocket fuel to storms.”

The counties projected to have storms Monday include Winnebago, Boone, McHenry, Lake, Ogle, Lee, DeKalb, Kane, DuPage, LaSalle, Kendall, Grundy, Kankakee, Livingston, Iroquois, Ford, Cook and Will counties in Illinois.

11. Dangerous line of severe t-storms moving across the Chicago metro area will move into NW Indiana ...

Dangerous line of severe t-storms moving across the Chicago metro area will move into NW Indiana through 415 pm. Seek shelter BEFORE the storms arrive! Widespread 70+ mph winds likely, isolated areas will see stronger winds & possible tornado and/or tornado-like damage!
