St. John Valley weather for Sept. 12-18, 2018
High pressure will build in Wednesday from Quebec and bring clearing skies and mild conditions. High pressure will crest over the Valley Thursday then slowly drift east into the weekend, with mostly clear skies and mild conditions across the SJV. Skies become partly cloudy Sunday as a weak cold front approaches, and this system may produce a few showers Sunday afternoon and evening. Monday keeps a chance for showers as another cold front approaches from the northwest with a chance for showers lingering into Tuesday.
