IN A FLASH, HEAVENS ROARED

Over four hours, about a half-year's worth of lightning bolts bombarded the Chicago area, electrifying the night sky as trees were split, transformers were zapped and houses were set ablaze.
As work crews picked up Tuesday from the previous night's storms, meteoroligists were assessing the staggering power of a historic thunderstorm.
Nearly 90,000 thunderbolts had hit northern Illinois, according to the National Lightning Detection Network. At the storm's peak, it was firing off more than 800 bolts per minute-and that only counts those that hit the ground.
"There was no precedent for this," said WGN meteoroligist Tom Skilling. "In every way imaginable, that storm last night was in its own league."
The electrical storms raked the city and suburbs, bringing the Cubs game to a halt, sending residents into their basements and knocking out power to hundreds of thousands of customers. Remarkably, no injuries from the lightning were reported.
The awesome display originated in the unstable, Amazon-like humidity that built up Monday afternoon, filling the air with potential energy, meteoroligists said.
6 Months is the time period it ususally takes to record the number of lighting strikes that occured Monday night in the Chicago area.
