Potential Nor'easter Threatens Northeast with Rain and Snow as Cold Air Grips Eastern U.S.
A potential nor'easter is expected to impact the Northeast later this week, bringing a combination of rain, snow, gusty winds, and the first frost and freezes for millions. A deep dip in the jet stream, known as a trough, will bring significantly colder air across the East, causing temperatures to plummet by 20 degrees from Wednesday to Friday, from Chicago to Atlanta. By the weekend, lows could drop into the 30s as far south as the Florida Panhandle. A low-pressure system will develop over the Midwest by Wednesday, strengthening as it moves into the Ohio Valley Wednesday night, bringing rainfall from Georgia to Michigan. This system will then shift east, interacting with the surging cold air, leading to the first chances of snow across interior regions of the Northeast by Thursday night, including lake-effect snow bands from the Great Lakes.
