DAYS 1-5 (DECEMBER 14-18)<\/p>\n\n\n\n
Large scale blocking goes on, driven by Canadian high pressure. A large offshore storm pushed a cold front through the region overnight, accompanied by snow showers, which coated the ground in some places, but much of that then blew into crevices by strong winds behind the front. The gusty winds will continue today but with lots of sun and passing clouds. A few of these clouds may produce a snow flurry, but the better chance of this will be over Cape Cod. It will feel quite a bit colder than yesterday, even though the temperature is only slightly lower, due to the stronger wind and resultant wind chill effect. The gusty wind keeps up this evening then starts to relax overnight while shifting to northeast as low pressure to the east starts to lose influence and high pressure to the north drives the air flow. With time, that will combine with the air flow around the approaching low from the southwest, turning the wind more easterly as Thursday goes on. This brings in ocean stratus, while clouds from the approaching low will be coming in above those, so Thursday turns out to have little or no sun. Low pressure is set to track just south of our region on Friday, an elongation \/ redevelopment of an initial storm that was entering the Great Lakes region, as described in previous discussions. It’s pretty apparent now that this will be a mainly rain event for the WHW forecast area, although there could be some snow with a bit of accumulation at the start over interior higher elevations of central MA to southwestern NH, but too much mild air from the ocean means all areas are rain for the bulk of the event. There may be a decent temperature contrast on Friday, as the storm’s main precipitation shield passes through, depending on the exact track of low pressure. If it comes up across far southeastern MA, a quick jump to 50+ temps may occur over Cape Cod and the Islands, while it’s quite a bit cooler off to the north and west. As low pressure pulls away on Saturday, improvement will be slow to occur, and the return of colder air means that precipitation can switch from rain back to snow …. however … this will be taking place after the main precipitation has departed, so I am only expecting a transition from lingering rain showers to snow showers. Colder air moves in for Sunday but the passage of upper level low pressure and a trough that was once the initial storm means a few snow showers may occur. Otherwise expecting a mainly dry Sunday.<\/p>\n\n\n\n
TODAY: Sun, occasional passing clouds. A few snow showers possible near eastern coastal MA but especially Cape Cod. Highs 32-39. Wind N 10-20 MPH, higher gusts.<\/p>\n\n\n\n

THURSDAY: Mostly cloudy. Highs 36-43. Wind NE to E 5-15 MPH.<\/p>\n\n\n\n
THURSDAY NIGHT: Thickening clouds. Rain arriving overnight, may start as snow away from the coast, especially higher elevations of central MA and southwestern NH where a coating to 1 inch of snow may fall initially. Lows 31-38 evening followed by a slow temperature rise overnight. Wind E 10-20 MPH, gusts 25-35 MPH, strongest coastal areas.<\/p>\n\n\n\n
FRIDAY: Cloudy with rain likely. Areas of fog. Highs 38-45 north and west of Boston, 45-52 Boston southeastward, mildest over Cape Cod and Islands. Wind E 10-20 MPH, gusts 25-35 MPH, strongest coast, may shift to S late day over Cape Cod and Islands.<\/p>\n\n\n\n
FRIDAY NIGHT: Overcast with rain likely through the evening hours, tapering off to rain showers overnight. Lows 35-42. Wind briefly variable around Cape Cod otherwise E to NE 10-20 MPH with higher gusts evening, shifting to W overnight.<\/p>\n\n\n\n
SATURDAY: Mostly cloudy to partly sunny. Rain showers may turn to snow showers from west to east before ending. Highs 38-45 morning, then turning colder. Wind W to NW 10-20 MPH, higher gusts.<\/p>\n\n\n\n
SATURDAY NIGHT: Partly cloudy. Lows 22-29. Wind NW 10-20 MPH.<\/p>\n\n\n\n
SUNDAY: Partly sunny. A passing snow shower possible. Highs 33-40. Wind NW 5-15 MPH, higher gusts.<\/p>\n\n\n\n
DAYS 6-10 (DECEMBER 19-23)<\/p>\n\n\n\n
A dry, cold pattern is expected for a good portion of the week leading up to Christmas, but we’ll be watching for low pressure to impact the region late in the week – far too soon to speculate on any details with this possible system.<\/p>\n\n\n\n
DAYS 11-15 (DECEMBER 24-28)<\/p>\n\n\n\n
One or two potential disturbances with precipitation chances, otherwise mostly dry with temperatures averaging near to below normal.<\/p>\n","protected":false},"excerpt":{"rendered":"
