From the WABI-TV5 & CW Forecast Center:
The ridge of high pressure that brought the chilly conditions to New England Friday will settle to the southeast of New England Saturday. As the high settles to the southeast of New England a developing southwest breeze on the backside of the high will usher milder air back into our region. As the southwest breeze continues on Sunday the atmosphere will continue to warm all across New England. A warm front will brings increasing clouds to Maine Saturday and likely produce some scattered showers across New England Sunday. Also on Sunday a trough of low pressure aloft will likely combine with an onshore breeze to bring more scattered showers and patchy drizzle to eastern parts of Maine. High temps Saturday throughout Maine will run in the low to mid 60s, with highs Sunday likely ranging from the mid 60s north to the low 70s south.
A cold front crossing the Northeast will bring more scattered showers to our region Monday. Brighter and drier conditions will move back into New England Tuesday as the front moves off to our east and high pressure approaches from the west. The high will likely produce another pleasant day across our region Wednesday. High temps Monday will climb into the low to mid 60s across most of Maine, with slightly cooler conditions moving into the state for both Tuesday and Wednesday.
Saturday: Partly sunny start, with increasing clouds late and high temps in the low to mid 60s.
Saturday night: Mostly cloudy, with patchy fog and drizzle likely and low temps in the upper 40s to mid 50s.
Sunday: Partly to mostly cloudy, with scattered showers likely and high temps in the mid 60s to low 70s.
Monday: Partly to mostly cloudy, with scattered showers likely and high temps in the 60s.
Tuesday: Partly sunny, breezy and cooler, with high temps in the upper 50s to mid 60s.
Wednesday: More sun than clouds, with high temps in the upper 50s to mid 60s.
