OMAHA, Neb. (AP) — Baseball-sized hail is breaking windows and tearing the siding off homes in northeast Nebraska, and forecasters are warning residents across the nation’s midsection to brace for “life threatening” storms. The National Weather Service says at least three possible tornadoes were reported early Saturday in central Oklahoma, while hail and rain were pelting Nebraska by early afternoon. No injuries were immediately reported. But forecasters are expecting the most dangerous weather later in the day and are warning residents across the region of possible fast-moving overnight tornadoes. Officials say a large area spanning from Minnesota to Texas could be at risk. In Nebraska, Boone County Sheriff David Spiegel says large hail has damaged vehicles, shattered windows and ripped the siding off of houses in and around Petersburg, a town about 140 miles northwest of Omaha.
