Bit Milder Friday, Rain Arrives Saturday 

From the WABI-TV5 & CW Forecast Center:


The ridge of arctic high pressure that produced the fair, breezy and cold conditions across Maine the past three days will slip east off the Mid-Atlantic Coastline tonight. After mostly clear skies early tonight clouds ahead of a weak disturbance aloft will begin to push into mostly southern parts of our area. Low temps tonight will range between -7 and +7, with the coldest reading being found north of the Bangor region.

The weak disturbance aloft will keep skies partly to mostly cloudy Friday, with nothing more than a few light snow showers falling. The best chance of seeing the snow showers will be south of the Bangor area as the disturbance crosses Southern New England. Temps will moderate Friday as the high currently over the Mid-Atlantic Coastline moves offshore and a southwest breeze develops here. High temps Friday will reach up into the 20s to near 30, which is near normal for this time of year. An increasing southerly wind will bring mild air and developing rain to New England Saturday as an intensifying storm slides north through the Great Lakes Region well west of Maine. Inland precipitation may briefly start as an icy mix Saturday morning before milder air at all levels of the atmosphere causes precipitation to become all rain by noontime statewide. The storm will likely bring a period of moderate to heavy rain to all of New England later Saturday into early Sunday, with up to 2” of rain falling in many locals. The heavy rain and melting snow could lead to localized flooding from later Saturday into early Sunday.

Slightly cooler air will move back into our region Sunday as the wind shifts into the northwest behind the storms trailing cold front.  A few more rain or snow showers may fall Sunday as the cooler air spills back into Maine, but temps will still run a few to several degrees above normal. A weak ridge of high pressure will bring Maine a partly sunny and mild start to the workweek Monday. Another storm may move up the Eastern Seaboard Tuesday or Wednesday and bring more rain or snow back to our region as temps will continue to run above normal.


Tonight: Mostly clear to partly cloudy and cold, with low temps in the range of -7 to +8.


Friday: Partly to mostly cloudy, with possible snow showers south and high temps in the 20s to near 30.
