An early spring storm off the coast of Maine is expected to pummel some parts of the state with as much as a foot of snow before it leaves the region Monday afternoon. Portland could be in line to get 3-6 inches of snow, while parts of Down East Maine could see anywhere from 10 to 12 inches, according to the National Weather Service in Gray. Sunday was the first day of spring, and Portland has received just a half inch of snow so far this month. Margaret Curtis, a meteorologist with the National Weather Service, said Portland and coastal communities are on the outer edge of the 500-mile-wide ocean storm, a situation that has produced a variation in forecasts.
