St. Lawrence County residents will again feel a nip in the air tonight, according to the National Weather Service.

Despite the fall-like weather today and tomorrow, due to cooler air flowing into the region from the north, forecasters say summer-like temperatures will return by mid-week.

High pressure is expected over the area tomorrow with primarily clear skies, which will remain the dominant weather feature through the weekend, forecasters say.
