For a really big winter storm, a low pressure system tracking right up the coast is required to produce a collision of the warm moist air off the ocean with the cold air mass over the land - a classic nor'easter. So far this season we have been dealt many glancing blows as storms have trundled by either to the west or to the east of us, but none as yet have had the right configuration for really big accumulations. This week is no exception; a promising low is gathering strength off the Carolinas. However, before it can wreak its havoc on us, it will be picked up by the prevailing mid-level flow and whisked off across the Atlantic. As the storm blows by, the onshore winds will be enough to produce clouds and scattered flurries especially near the coast. Wednesday night should also see some light snowfall as a weak system swings southeastward out of central Canada. Thursday will see the sun reappear, and to add to the frustrations of Massachusetts skiers, the long range models again have a powerful storm sliding by to the south of us during the early part of the weekend.

Today: Mostly cloudy but with occassional breaks. A brisk wind out of the northeast. A good chance of flurries. High 34F (1C).

Tonight: Some partial clearing of clouds, winds shifting westerly. Low 23F (-5C).

Wednesday: Mostly cloudy. Some moderation in temperatures. Scattered flurries out of the west during afternoon and evening. A chilly night. High 39F (4C). Low 21F (-6C).

Thursday: Becoming clearer. High around 35F (2C). Low around 20F (-7C).
