OMAHA, Neb. (Reuters) - Dreaming of a white Christmas has taken on new meaning for some Nebraska residents who may wake up on Dec. 25 to find themselves $10,000 richer. A car dealership in Omaha, Nebraska, is offering anyone who bought a vehicle between November and Thursday night $10,000 in cash provided it snows four inches (10.2 cm) on Christmas day. The company has even taken out a $1.5 million insurance policy with Lloyd's of London just in case it does snow. Sixty-seven people took up the offer from the dealership and have purchased a new or used car since the deal was launched in November to spur slumping year-end sales, Olsen said. In order for the money to be awarded, four inches of snow -- to be measured at an Omaha weather station -- must fall between midnight on next Wednesday and midnight on Thursday. Preliminary forecasts are calling for possible flurries in the Omaha area at Christmas, but little chance of four inches. "I wouldn't get my hopes up. It's a long shot," said meteorologist Jeff Wetzstein of Accu-Weather, a private forecasting service. "But you never know, things can change. It's still early."
