Unseasonably cool air from a Canadian high-prssure system will drop into the region tonight and bring a chance for patchy frost in the area, particularly along and east of a line from Roseau, Minn., south to Park Rapids, Minn., according to the National Weather Service office in Grand Forks.
But low-lying areas have a chance of feeling frost, too, the weather service says.
Another cold front is expected to drop through the region late Thursday afternoon and evening, with a few thunderstorms possible, the weather service says.
