There are several additions to the forecast from earlier this morning. A blizzard warning is now in place south of Boston including much of the South Shore, Cape Cod and the Islands.
Coastal flood warnings and advisories are in place for the time of high tide on Monday.
Heavy snow will commence during the morning Monday and then continue much of the day and perhaps into the overnight. Expect widespread cancellations.
Our Original Post From Sunday At 8 a.m.
The second snowstorm in less than a week will get underway on Monday with snow breaking out during the morning commute. The snow will be heaviest and steadiest south of Boston.
Winds will be strong over Cape Cod and blow the snow into drifts and also lower visibility. There may be near blizzard conditions at times in that area.
Tuesday morning there will be another coastal low pressure area passing south and east of Nantucket. This could bring more snow to coastal areas in the afternoon or evening, but presently it doesn’t look like a big storm.
For the New Hampshire area, some snow is possible, but since they are even further from the center of the storm it looks less likely that there will be accumulating snow on primary day, but stay tuned to the latest forecasts.
An arctic front goes by the area on Wednesday with some snow showers. This will usher in progressively colder air through the holiday weekend. (Presidents Day is Monday.)
The core of the cold arrives Valentine’s Day morning, with temperatures likely at their coldest levels of the entire winter.
