We've been dealing with some stubborn cloud cover today, along with our first snowflakes of the season (at least in the Greater Bangor area.) An upper level low is responsible for the clouds and flakes today; high pressure will boot that low off to the east tonight, so look for decreasing cloud cover.
Tuesday will bring more in the way of sunshine as high pressure does its thing; look for brisk temperatures with most of the Pine Tree State topping-out in the 30s to low 40s.
We've got some changes coming later Wednesday into Thursday as an area of low pressure tracks north along the mid-Atlantic. It appears the low will spead clouds into Maine Wednesday, with a chance of mixed precipitation, including some snow arriving Wednesday night. That snow will mix with sleet and rain in the Bangor area toward the coast, so I don't anticipate any significant accumulation in that region. However, north of Bangor there could be some plowable snow by mid morning Thursday. As usual, it all depends on the exact track of the low; if it hugs the coastline we will see mostly a change to rain for much of the area, if the low tracks more to the east, the cold air in place will help to produce more in the way of snow. Keep checking back with us for the lastest forecast as we get closer! In the meantime, plan for at least a messy, and possible slick morning commute on Thursday.
