St. John Valley Weather, Jan. 18-24, 2023

3-Day Outlook: Wednesday- Friday

Low pressure in the Maritimes will lift towards Labrador today with wrap around moisture producing some snow across the Valley. Around 1-inch of additional accumulation is expected by evening. Northwest winds pick up this evening as a cold front moves through and Canadian high pressure builds into the region with drier air. 

Partly sunny skies are expected Thursday as high pressure builds into the region with colder air aloft trapping some moisture closer to the surface to produce some cloudiness. Cloud skies are expected to develop Thursday evening as low pressure tracks east from the Great Lakes.

The low will bring a slight chance for some morning snow to Fort Kent and vicinity Friday; however, its track is far enough south that mostly cloudy skies will be the main feature from this system. Partly cloudy skies and cold temperatures are expected Friday night into Saturday morning.

4-7 Day Outlook: Saturday – Tuesday

High pressure will build across the SJV Saturday and Saturday night with partly sunny/partly cloudy skies Saturday and mostly cloudy skies overspreading the region Sunday. Low pressure is expected to track towards Maine from Ohio Valley/Mid-Atlantic bringing cloudy skies and a chance for snow Sunday night and Monday. While the exact track of this system is not certain, several longer-range models indicate that this will be a snow event for northern Maine. However, the ultimate track will determine precipitation type and amounts. High pressure will build in with partly cloudy/partly sunny skies and breezy conditions Tuesday.
