 SYNOPSIS: The extended summer is ending. It’s been a great run with bonus weeks of seasonably warm conditions. Fall takes over by midweek, and everyone in Maine will know it. The region of interest for me heading into the week is the Pacific Northwest and Alaska regions. We’re heading into a more unsettled, cooler pattern. The strong ridge out west appears to drift to the east, but it won’t affect our area much. What will affect us is the top end of the dome getting hammered with disturbances as strong upper lows spin around Alaska, which will unload offshoots that funnel in our direction. With those disturbances comes cooler air and chances for precipitation. I am seeing hints in the longer range that some of that precipitation may be of the frozen variety, which isn’t a surprise given where we are on the calendar. While I am not expecting much more than charity flakes for the western mountains in the next 10-14 days, it’s a signal for what will come.  SHORT TERM THROUGH TUESDAY: Clouds increase on Sunday as a cold front approaches from the west, but the day stays dry. Rain breaks out over the west and south in the wee hours of Monday, then overspreads eastern and northern areas Monday morning. Rain continues Monday night, ending from southwest to northeast gradually during the day on Tuesday. Northern areas may see precipitation hang on into Tuesday night, ending Wednesday morning. Clouds clear out behind the system and sets up the first widespread frost of the season Tuesday night. Expect areas of fog around the region through Tuesday, with some lake steam possible Wednesday morning. Wind speeds appear on the lighter side overall. The north and mountain areas may see some breezy conditions as the system heads into the Gulf of St. Lawrence on Tuesday.  LONG TERM WEDNESDAY to SATURDAY: An upper low spins overhead, creating various amounts of cloud cover. With cold air aloft, any sun will generate convective rain/snow shower potential over the higher terrain, along with northern areas. The upper low exits the region on Thursday. High surface pressure works in on Friday and hangs on through Saturday.  Your support for 2025 is greatly appreciated! Always have MULTIPLE ways to receive weather alerts.
