St. John Valley weather for Nov. 14-20, 2018

Low pressure moving east in the Maritimes will deepen and interact with an incoming ridge of high pressure to create gusty northwest winds across the Saint John Valley Wednesday with areas of blowing snow and low visibility at times before winds will subside Wednesday evening. High pressure will build across the area Thursday followed by increasing clouds Friday as low pressure tracks from Cape Cod towards Nova Scotia Friday. Snow is likely through the day Friday with several inches accumulation for Fort Kent and the northern border region of the County.

A cold front will move through the region Saturday with snow showers lingering across the region. High pressure builds in Sunday into Monday. Clouds increase later Monday as a front approaches from the west/northwest with a chance for snow Monday afternoon and evening tapering to snow showers Monday night into Tuesday.
