LINCOLN –Gunfire, that’s what it sounded like Sunday in Lincoln as four inches of snow brought tree branches full of leaves to the ground. Neighborhoods getting ready for Halloween spent much of Sunday cleaning up from the rare October snow surprise. Downed power lines meant thousands without power. LES says about 3,500 people were without power by 4 PM Sunday. Most main roads were passable but out in Lancaster County, roads were slick and caused an SUV to slide off the road and into a tree according to a deputy’s tweet. Authorities say that thanks to seat belt use there were no injuries. City crews started applying brine salt Saturday at midnight and other than a few accidents on East “O” Street, main roads were open and accessible. LPD did confirm that stoplights at several intersections were out of service causing further delays.
