Apex Weather

St. John Valley weather for Sept. 27-Oct. 3

A cold front stalled across the mid-state region will lift north as a warm front triggers showers and thunderstorms Wednesday afternoon with precipitation continuing into the overnight period. Clearing skies and much cooler temperatures will move in behind the front Thursday. High pressure near the Great Lakes will move east into the Middle Atlantic region Friday through Monday with cool, dry weather for the Valley with the possibility for some frost in sheltered areas in the Allagash region Saturday night. A reinforcing shot of cool air pushes down out of Canada behind a weak cold front Monday with mostly clear and dry conditions continuing into Tuesday.
