From the WABI-TV5 Forecast Center:

An upper level storm slowly drifting across southeastern Canada and the Northeastern States will keep the skies across Maine partly to mostly cloudy tonight and tomorrow. The upper level low will bring the risk of a few scattered snow showers tomorrow, with the western Maine mountains likely seeing the bulk of the flurries and snow showers. Temps tonight and tomorrow throughout the Pine Tree State will be normal or slightly below normal as lows tonight fall into the upper single numbers to mid-teens, with highs tomorrow ranging from the mid-20s north to the mid-30s along the coast..
A small bubble of high pressure approaching New England from the west will bring Maine a slightly brighter day Sunday, with temps once again running near normal for the beginning of March. A weak storm and frontal system will likely bring a few snow or mixed rain and snow showers to Maine later Monday, with temps climbing back to above normal levels. Tuesday will be generally fair and milder as temps reach up into the low to mid 40s across most of our region.
A storm moving into the Northeast will likely bring a period of steadier precipitation to New England Wednesday, with the exact track of the storm determining precipitation types across Maine. At this point in time it appears the storm will move over New England or up to the west of New England and that would cause much if not all the precipitation to fall as rain across our area as a southerly breeze on the east side of the storm pulls a milder than normal air-mass up into Maine.

Tonight: Mostly to partly cloudy, with a westerly breeze diminishing to under 10 mph and low temps running in the upper single numbers to mid-teens.

Saturday: Variably cloudy, scattered flurries and chilly, with a westerly breeze between 5 and 10 mph and high temps in the mid-20s to mid-30s.

Sunday: Partly sunny, with high temps in the mid-20s to near freezing.

Monday: Partly to mostly cloudy, with possible snow and rain showers developing and high temps in the 30s.

Tuesday: Variably cloudy, with high temps in the upper 30s to mid-40s from north to south.

Wednesday: Rain and mixed precipitation likely, with high temps in the upper 30s and 40s.
