DAYS 1-5 (DECEMBER 9-13)<\/p>\n\n\n\n
No notable changes for today’s discussion from yesterday’s. A warm front approaches today and tonight and a short wave disturbance aloft comes through this evening. While there is dry air to overcome at mid levels, this feature is expected to produce a brief period of snow late evening into the overnight hours from west to east, except mix to rain closer to Cape Cod where the temperature will be borderline between supporting frozen and liquid precipitation. If any accumulation of snow occurs with this, it will be minor and mostly away from the coast northwest of Boston. We end up in the “warm” sector for Wednesday, not an overly warm day by December standards, but milder than recent days for sure. A cold front trailing low pressure passing to our north will sweep through with the air mild enough for rain showers in the evening, again progressing west to east but lasting no more than a couple hours in any one location. This front will lead a colder air mass back into our region for Thursday through Saturday. Thursday’s weather will be windiest, with a gradual abatement of the wind on Friday and a more tranquil Saturday as high pressure builds toward the region. Upper level low pressure crossing the region, combined with limited Great Lakes moisture, can result in a few snow showers around the area Thursday. This threat will diminish then vanish for late week as the upper low departs and the wind relaxes.<\/p>\n\n\n\n
TODAY: Sun gives way to clouds. Highs 28-35. Wind variable to SE up to 10 MPH.<\/p>\n\n\n\n
TONIGHT: Cloudy evening into overnight with a period of light snow\/mix except mix\/rain South Coast. Snow accumulation of up to but mainly under 1\/2 inch can occur mainly inland areas to the north of I-90. Watch for icy spots on untreated surfaces mid to late evening except Cape Cod \/ Islands. Lows 20-27 except steady 28-35 southeastern MA and southern RI evening, rising slowly overnight. Wind SE under 10 MPH shifting to SW up to 10 MPH.<\/p>\n\n\n\n
WEDNESDAY: Partly sunny morning. Mostly cloudy afternoon. Late-day rain showers from west to east, but may be mixed with snow in higher elevations from north central MA through southwestern NH. Highs 38-45. Wind SW 5-15 MPH.<\/p>\n\n\n\n
WEDNESDAY NIGHT: Mostly to partly cloudy. Rain showers possible in eastern areas in the evening. Icy areas on untreated surfaces overnight. Lows 28-35. Wind NW 5-15 MPH.<\/p>\n\n\n\n
THURSDAY: Sun\/cloud mix. Chance of snow showers. Highs 32-39. Wind NW 10-20 MPH, higher gusts.<\/p>\n\n\n\n
THURSDAY NIGHT: Partly cloudy. Chance of a snow flurry. Lows 17-24. Wind NW 5-15 MPH.<\/p>\n\n\n\n
FRIDAY: Partly to mostly sunny. Chance of a snow flurry early. Highs 34-41. Wind NW 5-15 MPH with higher gusts, gradually diminishing.<\/p>\n\n\n\n
FRIDAY NIGHT: Partly cloudy. Lows 11-18 except 18-25 coastal and urban areas. Wind W under 10 MPH.<\/p>\n\n\n\n
SATURDAY: Partly cloudy. Highs 31-38. Wind W up to 10 MPH.<\/p>\n\n\n\n
DAYS 6-10 (DECEMBER 14-18)<\/p>\n\n\n\n
Low pressure brings a chance of snow except snow\/mix\/rain South Coast during December 14, this being the next in a series of clipper-style low pressure areas. Watching for another system with a precipitation threat around December 17 but less confident on timing. Temperatures mostly below normal for the period.<\/p>\n\n\n\n
DAYS 11-15 (DECEMBER 19-23)<\/p>\n\n\n\n
Divergence in medium range guidance – nothing new there – doesn’t help forecast confidence atop the normal lower confidence for a period of time this far in the future. For now, the same idea applies. Watching for a brief warm-up from a Great Lakes low then a return to the colder pattern and back on the watch for clipper disturbances as the cold air wins out over a warmer area of air to our south. Caveat: There is enough push from medium range guidance including some ensemble support of a milder scenario toward Christmas – the days just before – so I am not completely discounting a shift to a milder outlook than the one I have now, hence the mention of low confidence.<\/p>\n","protected":false},"excerpt":{"rendered":"
