Apex Weather

St. John Valley weather for May 13-19, 2020

Short-Term Outlook: Wednesday – Friday

The strong low-pressure that brought yesterday’s snowfall to Fort Kent and vicinity is near western Newfoundland this morning and circulation around the system will channel breezy northwest winds into the Valley. High-pressure over the Middle Atlantic brings drier air and mostly clear skies to partly cloudy skies today. Winds will diminish tonight with mostly clear skies across the region followed by mostly clear skies Thursday through the afternoon. Partly cloudy skies develop Thursday evening as a warm front ahead of a low-pressure system tracking east from the Great Lakes approaches. Mostly cloudy skies develop Friday with rain gradually overspreading Fort Kent and surrounding areas by the afternoon/evening period. Rain continues Friday night into Saturday morning.

Medium-Range: Saturday – Tuesday

Precipitation tapers off Saturday morning with partly cloudy skies developing as high-pressure builds in from the west. Partly cloudy skies Saturday night give way to mostly cloudy skies with a chance for rain showers by Sunday evening as a low-pressure system tracks towards the Valley from the southwest. Rain showers are expected across the region Sunday night through Monday night before tapering off early Tuesday. High-pressure builds east Tuesday with partly cloudy skies developing.
