From the WABI-TV5 & CW Forecast Center:
A front approaching New England from the west will bring increasing clouds to Maine this evening, with a bit of light rain and freezing rain possibly developing late. The best chance of seeing the light rain and freezing rain tonight will be over northern and western parts of Maine. Temps tonight will remain very mild for this time of year as lows hold in the mid 20s to mid 30s, with the coolest temps occurring in the valleys north and west of the Bangor region.
A small storm developing along the approaching front will bring a round of steadier precipitation to Maine tomorrow and tomorrow evening, with any freezing rain up north changing to plain rain during the morning hours as the temps warm well up into the 30s north and low to mid 40s south. Slightly cooler air will filter back into Maine later Tuesday night and Wednesday as the cold front moves offshore.
An upper level trough will gradually develop over the eastern parts of the U.S. as we head through the rest of the workweek and into the weekend. The trough will cause a series of storms to develop near the Eastern Seaboard as we progress through the week, but it is too tough to tell how close these storms will be to our region as they develop and thus how much precipitation they will produce across the Pine tree State later in the week and weekend. Each storm will pull cooler air into the New England area as it goes by and that brings increasing odds of precipitation falling as mostly snow towards the end of the week.
Tonight: Becoming mostly cloudy, patchy light freezing drizzle and drizzle developing late, with low temps in the mid 20s to mid 30s.
Tuesday: Early icy mix north then rain showers, with high temps in the upper 30s to mid 40s.
Wednesday: Variably cloudy, with high temps in the 30s to low 40s.
Thursday: Possible rain and snow showers, with high temps in the 30s to near 40.
Friday: Partly to mostly cloudy, with snow and mixed precipitation possible at night and high temps in the upper 20s and 30s.
Saturday: Snow and mixed precipitation possible, with high temps in the mid 20s to mid 30s.
