Today will feature an overrunning precipitation event with mainly light precip. Rain will be the dominant precip type along the coast with snow inland. It will be mild out there in the 30's and 40's.
With regards to the ice storm, it looks like the area most affected will be the foothills of Maine and the mountains of New Hampshire. Up to 3/4" of ice could fall in those areas. Heavy rain will be the big story across southern coastal Maine, southern New Hampshire and the rest of Southern New England. The mountains of Maine and far northern Maine, New Hampshire, and Vermont will see a mostly snow event from this which is good for the ski areas.
