Record-Challenging Chill for Omaha, Madison

A bubble of air, originating from the Arctic Circle in northwest Canada, brought a refreshing, but record-breaking chill across the northern Plains overnight.

Record heat has made headlines this summer, but chilly air and record lows will replaced them across the northern Plains Friday night. This is the chilliest air in the region since the spring.

Cites from Omaha to Kansas City to Madison, Wis., will attempt to break records overnight. Lows will range from the lower 40s across northern North Dakota and Minnesota to the lower 50s toward northern Kansas and Missouri.

The overnight lows are comparable to late September or early Fall.

"This is a big signal that summer is coming to a close," said Expert Senior Meteorologist Dale Mohler.

Clear skies, calm winds and the dry ground contributed to the chilly weather.

Despite the fact that the chill can make it into the record books, it was a refreshing, crisp night and one that will be welcomed, especially across the southern areas.

Daytime highs and nighttime lows will gradually rebound to more summerlike temperatures by early next week on the Plains.

A cold front, the leading edge of the chilly air, will move into the Northeast on Friday. The cold front will spark heavy thunderstorms Friday afternoon from New England south into Pennsylvania.

In wake of the front, the refreshing air will settle into areas from the Northeast south into the Tennessee Valley for the weekend.
