Watch for flying houses, especially if your last name is Pelosi!
This is the kind of storm that sank the Edmund Fitzgerald.
Are they expecting a massive drop in temperature too?
Our weather radar is down (Lincoln, Illinois) so it is a little hard to see what is going on. http://www.wandtv.com/Global/link.asp?L=246691 has a live doppler radar, but it doesn’t seem to have the time lapse capability. The system seems to be moving on to the east over Champaign now.
Gas grills and trees flying last night down here in the Ozarks. Still windy now, but not near as bad as at 2AM!!
Gonna watch this one come in over lake Michigan.

The legend lives on from the Chippewa on down
Of the big lake they call Gitche Gumee
The wind in the wires just now making a tattle-tale sound here in Southwest Michigan.
Well, poop! Its heading right straight for us. Got to go turn on the TV. Good luck everybody in the path of this storm.
Bad weather bump!
We got one in the ABQ metro area after this bad boy blew through last night, so I'd say yes.
Hey, that’s pretty cool!
Bad weather bump!
Amazing how they block out Canada in the graphic.
