BANGOR, Maine (WABI) - While we started out gloomy this morning drier air worked in behind the departing storm system leaving us with partly cloudy skies. Quiet weather will continue for the rest of the evening as high pressure ridges in from the northwest. With clear skies, lighter winds and cooler temperatures tonight, there is the threat of some frost developing, especially across northern Maine. A frost advisory is in effect for northeastern and southeastern Aroostook County and northern Penobscot county from 3 a.m. until 8 a.m. Monday morning. Overnight lows drop into the low to mid 30′s north to the low to mid 40′s through the Bangor region and Downeast.

High pressure will continue to ridge into the region on Monday, providing us with mostly sunny skies. With cooler and drier airmass in place, highs won’t be as warm as they are today, only reaching the low to mid 60′s across the state. Overnight low temperatures get even colder Monday, possibly dropping into the upper 20′s up north to the mid 30′s and low 40′s Downeast. High pressure remains in control on Tuesday. Expect sunny skies with high temperatures reaching the upper 60′s and low 70′s. Wednesday will also shape up to be a mostly sunny to partly cloudy day. However, a cold front will cross the state late Wednesday night, which will provide another chance for some rain showers. Scattered showers may linger into Thursday morning.
