New York City is coming off two rounds of rough weather already this first week in September, and a third system is lined up for tonight. But the freshest guidance out of the National Weather Service tells a different story than the one that's been circulating since Tuesday. Instead of extending Tuesday's storm warnings into tonight, forecasters have actually eased the overnight threat down to the lowest rung on the government's five-level severity scale, according to the local forecast office's discussion posted Wednesday morning. Thursday afternoon, not tonight, is now the stretch meteorologists say deserves the closer watch.
