St. John Valley weather for Jan. 11-17, 2023

3-day Outlook: Wednesday-Friday

High pressure in Quebec will slide to the east-southeast today with sunny skies across the Valley. Clouds increase tonight as an area of low pressure lifts towards the eastern Great Lakes and an associated warm front lifts northwards. Mostly cloudy skies develop Thursday with snow overspreading the Valley in the afternoon. Snow is likely Thursday night into Friday morning.

The low will track across the region Friday; however, timing and track are still uncertain at this time. Snow is expected to transition to a wintry mix Friday afternoon continuing as a rain/snow mix Friday night into early Saturday. Currently, 8-12 inches of snow accumulation are possible for northern portions of the County, 6-8 inches in central portions, and 4-6 inches in southern Aroostook.

4- to 7-Day Outlook: Friday-Monday

A wintry mix across the SJV transitions back to snow Saturday morning then tapers to snow showers in the afternoon as an upper-level trough associated with the low departing into the Maritimes moves across the region. High pressure builds in later Sunday with partly cloudy skies Monday. An oceanic low in the northwest Atlantic looks to track towards the Gulf of Saint Lawrence early next week bringing some clouds as well as a slight chance for wrap-around snowfall to the Valley; however, the extent of precipitation from this system is still uncertain and dependent on its ultimate track to our east.
