Summer to Return in Midwest; Northeast

More summerlike weather will return to the Midwest this weekend, followed by the Northeast early next week.

This warmer weather is returning after several days with temperatures running as much as 10 degrees below normal in cities such as St. Louis, Mo., Cincinnati, Ohio, Detroit, Mich., Pittsburgh, Pa. and Baltimore, Md.

This trend in warmer weather will start over the weekend across the Midwest as heat in the Plains begins to swell eastward.

The heat will continue to push eastward early next week, expanding across the Northeast, while building even more in the Midwest.

This change in the weather pattern is associated with the jet stream moving farther north, allowing for warmer temperatures to expand farther north with it.

This push of warm air may feel like a heat wave for some following the stretch of fall-like temperatures across the Midwest and Northeast; although no records are expected to be broken during this warmup.

Not only will temperatures be on the rise during this shift in weather patterns, but so will the humidity.

Higher humidity accompanying the warmer temperatures will make the AccuWeather.com RealFeel® higher than the actual temperature.

By late next week, a cold front will be swinging southward from Canada, taking aim at the Great Lakes region.

It is still unclear when this cold front will arrive or how strong it will be, but it could deliver another shot of unseasonably cool air to the Midwest and Northeast.
