BOSTON (CBS) – All eyes in the weather center are on Sunday’s predictions: No, not the Super Bowl … but the expected snowfall!
February is the second snowiest month in Boston, and the pattern ahead looks like Mother Nature knows.
Sunday snow moves quickly and arrives from late morning through afternoon. During the height of the storm, snowfall rates are between 1 / 2-1 inches per hour. The snow should rejuvenate after sunset. All said and done, there will be approximately 8-10 hours of snow before eviction begins for Monday.
Winter storm warnings apply to the Cape and Islands, as well as Bristol and Plymouth Counties. These are the areas where the heaviest snow is likely. Winter storm clocks have been issued for the rest of the viewing area, which will likely be converted into winter weather recommendations for the lower snow totals.
For most of this season, Corridor I-95 / Route 128 was used as the dividing line for rain and snow – the Cape gets the rain, Worcester County gets the snow. The roles are a bit reversed in this storm. 128 will serve as the approximate boundary between some of the heaviest snow totals. Bristol and Plymouth Counties in the Cape and Islands should expect 4-8+ inches of snow. Then 2-4 inches of snow is expected for Metro-West to Worcester and Middlesex Counties. Cape Ann could see some additional improvements allowing slightly higher totals, up to 6+ inches.
A few questions remain unanswered in this forecast. First … how much intermingling does the Outer Cape see, potentially reducing the snow totals there? How far does the heaviest band of snow extend northwest beyond 128?
As this storm is a swift blow, the greatest impact of the heavy afternoon snowfall will be felt on the road. Rain and wind are low overall.
The general pattern for storms is getting more and more favorable for the persistent snow probabilities in the coming week. When a cold mass of air settles in New England, multiple waves will attempt to take advantage of that cold.
The WBZ weather team monitors the Tuesday and Friday time frame for possible additional snowfall.
