A major storm will be impacting people who live in the East over the next few days. Severe storms, flooding, and a windswept rain will be unleashed by the storm.

The storm responsible for the widespread dreary and even threatening weather is gathering more strength in the Gulf of Mexico today. It will push into the South late tonight into tomorrow. By Wednesday and Thursday it will move northeastward to the west of the Appalachians and toward the eastern Great Lakes.

The greatest threat for severe storms and flooding will threaten lives and property in the Southeast to the southern mid-Atlantic coast. Northeasterners will deal with a dreary windswept rain that could create slow travel on roadways and airport delays. As colder air filters in behind the storm, rain will change to snow.

Places from Oklahoma City and Chicago will have rain change over to lightly accumulating snow. Detroit could end up having bigger travel disruptions from a moderate snowfall, but that will depend on how much cold air is in place.

A slight change in the track could mean the difference between heavy rain or a couple inches of snow with this storm. Keep checking back with AccuWeather.com for the latest on the storm and its impacts.
