So...my windshield broke this morning. There was a storm overnight, but I see no evidence that the storm caused the damage. I did not notice any hail, and there were no tree branches on or around the car. A series of cracks on the outer layer of the windshield fan out from the top center of the windshield where the rear view mirror is.

Last week I glued my rubber strip to the glass with 3M black weather strip adhesive. Could that have caused the glass to break? Seems unlikely, but I'm at a loss as to what caused the glass to crack up like that.
