Tonight through Saturday night...A dry northwest flow aloft is expected over the forecast area through Saturday evening. Cloudiness will increase near the Canadian border after midnight but am not expecting any precipitation. This cloudiness is associated with the weather system that will be affecting the area late in the weekend and early next week. A very weak front will move south over the area Friday morning and early afternoon. It will mainly bring a shift in light winds from the southwest to the north. High temperatures will still continue above normal the next two days.
