From the WABI-TV5 & CW Forecast Center:
After a bright start to our day the clouds will begin to push back into our region today as high pressure shifts off to our east. The clouds are associated with a disturbance aloft which will sweep into the Northeast later today. The disturbance aloft will force a new surface storm to develop near New York City this morning. The new storm will slide northeast and intensify as it passes through the Gulf of Maine just to the south of our region later this evening. The storm will bring a period of snow to our area later this afternoon and evening, with the steadiest snow likely falling from the Bangor region on south and east. Snowfall later today and tonight will range from 1 to 3″ north and west of the Bangor region to 3 to 6″ from Bangor on south and east, with possibly a bit more piling up in the Portland region.
A weak ridge of high pressure will bring fair skies to Maine Wednesday morning, but yet again a disturbance aloft approaching New England from the west will likely bring some snow and possibly some rain showers to Maine later in the day and night as it quickly develops a small storm in the Gulf of Maine Wednesday evening. High pressure will bring brighter and milder weather to our region Thursday, with a warm front likely producing some rain showers in much of Maine Friday along with milder than normal temps. Cooler air will begin to filter back into New England over the weekend as a cold front slips through our region later Friday night and Saturday morning.
Today: Increasing clouds, with snow likely developing later in the day and continuing at night, with high temps in the 20s to near freezing.
Wednesday: Partly to mostly cloudy, with more snow and rain showers possible later in the afternoon and evening, with high temps in the upper 20s to mid 30s.
Thursday: Partly sunny and milder, with high temps in the 30s to low 40s.
Friday: Mostly cloudy, rain showers likely and high temps in the upper 30s to mid 40s.
Saturday: Variably cloudy, with mountain flurries and cooler, with high temps in the upper 20s north and 30s to near 40 south.
