St. John Valley weather for Sept. 11-17, 2019

ST. JOHN VALLEY, Maine — An area of low pressure will track across northern Maine this Wednesday morning into the afternoon pulling a cold front across the region. Rain is expected across the SJV ahead of the front which will taper to showers once the front moves through this afternoon. Partial clearing overnight is expected as high pressure over central Canada builds east into the region with partly cloudy skies expected Thursday and mostly clear skies and frosty conditions likely across the region Thursday night. High pressure continues to bring mostly clear skies to the region Friday. A front approaches Friday night with increasing chances for rain after midnight. A cold front moves through Saturday with rain likely across the Valley. Showers Sunday morning taper off in the afternoon then pick up again Sunday night as a disturbance moves across the region with partly cloudy/partly sunny skies Sunday night and Monday and a chance for showers. High pressure brings partly cloudy skies to the region Monday night and Tuesday.
