DAYS 1-5 (DECEMBER 20-24)<\/p>\n\n\n\n
The coldest air mass of the season so far is on the way. Before it gets here, a minor winter weather event takes place today into tonight with an east to northeast air flow off the ocean around a storm system well offshore to our southeast, eventually tracking into the waters well to our east. This will help pull down cold air as we go through today. Ocean-effect precipitation is underway and will initially be in the form of either rain, sleet, or snow showers (rain showers most likely closer to the coast of the South Shore and Cape Cod), becoming snow showers for all with time. Additionally, expansion and development of the synoptic precipitation area will deliver some steadier snowfall mainly from the I-95 belt eastward, with lighter and somewhat more spotty snow extending further west. Out on Cape Cod, the warmer ocean water will impact the ability of snow to accumulate, so that reason there and the lighter precipitation amounts to the west will be the reason I’m going for under 1 inch of snow in those areas, with a general 1 to 3 inch snowfall elsewhere. The “higher” amounts of that range will occur where both ocean-effect and synoptic snow are maximized, and I cannot rule out a spot amount above 3 inches. This weekend will feature well below normal temperatures – the coldest air of the season so far. We welcome winter with the occurrence of the solstice at 4:20 a.m. Saturday, and that day will be quite breezy with the potential for scattered snow showers as an upper level disturbance moves through. Ocean enhancement of snow showers is possible over Cape Cod. The wind will slacken somewhat for Sunday and dry weather is expected except for the possibility of a few more ocean effect snow showers for the outer portion of Cape Cod. High pressure will provide “halcyon” weather for Monday – bright, dry, cold. A weak clipper low pressure system arrives via the Great Lakes Tuesday (Christmas Eve) with some light snow or snow showers possible. More about this potential in upcoming posts.<\/p>\n\n\n\n
TODAY: Cloudy. Ocean-effect snow showers except snow, sleet, or rain showers at first MA South Shore to Cape Cod. Steadier light snow except rain or snow at first Cape Cod later in the day.

DAYS 6-10 (DECEMBER 25-29)<\/p>\n\n\n\n
High pressure will become the dominant force in our weather holding off unsettled weather producing systems. Temperatures moderate to above normal, but not to any extreme.<\/p>\n\n\n\n
DAYS 11-15 (DECEMBER 30\u2013 JANUARY 3)<\/p>\n\n\n\n
Pacific-dominated air flow brings milder weather but minor precipitation threats as end 2024 and start 2025, but a stronger cold front may return Canadian cold to our region before the end of the period.<\/p>\n","protected":false},"excerpt":{"rendered":"
