DAYS 1-5 (NOVEMBER 15-19)
A cold start today, quite frosty in some areas with high pressure overhead. A light northerly air flow has driven some ocean effect clouds over Cape Cod but those will move out / dissipate early today as the high pressure area shifts to the south and our air flow across the region becomes light west to southwest. While this is happening, warmer air will be advecting in above us and create a variable amount of high cloudiness as the day goes on. These clouds will peak this evening before clearing out overnight as a warm front moves quietly through the region. What this front will do is boost Thursday’s high temperatures by about 10 degrees over today’s chillier readings. Another dry day is in store for us Thursday. Things start to change on Friday with high pressure further offshore and a low pressure trough approaching from the west. A southerly air flow will increase the moisture and resultant cloud cover in the region, and at the same time we’ll be watching a plume of moisture associated with a developing low pressure area to the south. This storm will pass by to the southeast of New England Friday night into Saturday while the trough to the west sends another low to our north, and its trailing cold front moves eastward across our region. This is a recipe for some wet weather with showers from the cold front, but also a swath of rain from the coastal / ocean low. The latter looks like it will have the greatest impact to the east of I-95 during the first 12 hours of Saturday before it starts to exit to the northeast and the cold front pulls through. This will shift the wind flow to northerly and drive drier, colder air into the region, and as these systems fully phase in eastern Canada we can expect dry weather but a gusty, chilly day on Sunday to finish the weekend.
TODAY: Early morning clouds exit Cape Cod, otherwise sun and high clouds. Highs 47-54. Wind N under 10 MPH except up to 10 MPH Cape Cod early, then shifting to W-SW up to 10 MPH.
TONIGHT: Lots of high clouds evening, then a clearing trend overnight. Lows 36-43. Wind SW up to 10 MPH.

FRIDAY NIGHT: Mostly cloudy with a chance of rain showers evening. Cloudy overnight with rain likely, especially from the I-95 belt eastward. Lows 48-55. Wind SW 5-15 MPH.
SATURDAY: Cloudy through midday with rain likely I-95 belt eastward and a good chance of showers elsewhere. Mostly cloudy with a few lingering rain showers possible in the afternoon. Highs 50-57 occurring in the morning, then cooling into the 40s. Wind variable 5-15 MPH becoming N and increasing to 10-20 MPH with higher gusts, especially eastern coastal areas.
SATURDAY NIGHT: Clearing. Lows 28-35. Wind N-NW 5-15 MPH, higher gusts.
SUNDAY: Sun and passing clouds. Highs 42-49. Wind NW 10-20 MPH, higher gusts possible.
DAYS 6-10 (NOVEMBER 20-24)
High pressure brings dry and seasonably chilly weather early next week. Watching for a progressive system to pass by during November 22 with a good chance of precipitation, mostly rain, but may start as snow/mix to the west/north favoring higher elevations if it comes in quickly enough. Thanksgiving Day looks dry and breezy, but not too chilly. Colder air arrives the day after that with a secondary cold front moving through that may produce a rain or snow shower with otherwise dry weather expected.
DAYS 11-15 (NOVEMBER 25-29)
Pattern looks dry for the balance of Thanksgiving Weekend before the precipitation chance goes up early the following week with a progressive trough arriving.
