Harvey remnants may visit Maine over Labor Day weekend

High pressure controls the weather pattern for the state through Wednesday. A cold front advances from Quebec into the area on Thursday. A taste of fall arrives with cool air for Friday. The remnants of Harvey may affect the region in the latter half of Labor Day weekend.

Wednesday / Thursday

High pressure provides enough of a buffer to keep a tropical low well to the south. High clouds from the passing storm decrease during the day. As the tropical low moves east, it takes high pressure with it. A cold front over eastern Canada enters the region for Thursday. Showers are possible for most of the state, with the exception of southern areas which appear to stay mainly dry.

Friday / Saturday

After the cold front passes through, the coolest air yet this fall arrives ahead of the weekend. The rooftop of the state appears to struggle to reach the 50° mark, while the coast reaches the mid-60s for a high temperature. A stiff breeze from the northwest is likely to be noticeable and add a pinch to the air especially in the north and mountain regions. A shower is possible over the Crown, ending Friday afternoon.

High pressure settles over the region Friday night, and may bring a touch of frost in well protected valley areas of the state by daylight Saturday morning.

Saturday appears to be the pick of the weekend at this point, with mainly sunny conditions and temperatures roughly 5 to 10 degrees warmer that Friday, and less breezy.

Sunday / Monday / Tuesday in question

I will preface my synopsis here to say model agreement breaks down at this point of the forecast. Changes are likely, and this will be updated.

Sunday at this point is questionable. A weak trough in combination with Harvey remnants may bring shower activity to the state. It does not appear that the day will be a complete washout, but for now it is a bit too early to tell.

For Monday, a weak cold front may bring showers to the mountains and northern areas, and perhaps an isolated shower for the foothills and eastern areas, ending in the afternoon.

The sky clears out Monday night, bringing a mainly sunny start to Tuesday. Clouds may increase in the afternoon ahead of a cold front which may affect the middle part of next week.

Seven day outlooks

NOTE: For the western mountains and north, frost may be possible in areas Thursday and Friday nights.
