Forecast: Snow And Rain Today, Arctic Air Arrives Tomorrow

There's lots of weather happening over the next several days, including snow, rain and a lot of cold.

Today we see a low pressure area crossing New England with snow to the north and rain showers to the south. As the storm passes to our north, colder air will be dragged into the system, moving the rain/snow line down into Boston. I don't expect much in the way of snowfall along the coastline. There will be a coating up to an inch as you get toward the Route 128 belt later this afternoon.

Across northern areas of Massachusetts, where the snow is most consistent, there could be anywhere from 2 to 5 inches of snow, with a few places in the highest elevations nudging toward 6 inches. If you are traveling in those areas, conditions will be worse so be sure to allow for extra time. South of Boston we're just looking at some rain that could end as a brief wintry mix.

Wednesday features mostly sunny skies, but it will be quite cold. We'll be watching an Arctic front head toward New England, and behind that could be some of the coldest November temperatures on record.

Thanksgiving could be one of the coldest ones on record. We'll have to wait for the final numbers to call it, but it's likely to be the coldest Thanksgiving any of us will have ever experienced.

Temperatures do moderate a bit on Friday, with dry weather continuing into Saturday. A new storm system will begin to form sometime later this weekend and likely bring a period of rain which could turn quite heavy early next week.

Across the rest of the country the weather will be rather tranquil, although a storm system coming into the West Coast will bring rain to that area.
