A warm front is sweeping springlike weather across a large swath of the country in what is usually one of the coldest months of the year. The rare warmup is sending people out of their homes to enjoy the winter respite but also bringing increased wildfire danger. The temperature on Sunday in Omaha, Nebraska, broke 65 degrees on a day when the average high temperature is around the freezing mark. Temperatures also reached into the 60s in Denver, Chicago and Des Moines, Iowa. Kansas City saw temperatures in the mid-70s. The National Weather Service has issued red flag warnings and fire weather watches for nearly a dozen central U.S. states.
