Snow began falling late Saturday morning and is expected – depending on your location – to intensify between 3 p.m. and midnight.

As usual, forecasts vary. The norm predicted for Boston and vicinity ranges from seven to 14 inches.

Boston Mayor Marty Walsh and other municipal officials have asked motorists to stay off the roads – not only for their own safety, but also to allow workers to sand and plow.

Cape Cod and the Plymouth-County shore are expected to receive the worst, with the National Weather Service issuing a blizzard warning. That means heavy snow with high winds.

The area from Boston west to Worcester, and Newburyport south to New Haven could see heavy snow with some wind.

South New Hampshire through central Massachusetts and mid Connecticut should count on snow without much wind.

Sunday throughout New England south of Maine and Vermont will see temperatures in the 20s with overcast skies.

Monday will be sunnier, but a bit colder.
