The Week Ahead


High pressure will dominate just about all week, keeping unsettled weather away. A cold front may make it in by Sunday with a threat of showers, but even that may be limited. Temperatures will run above to much above normal, with a lingering taste of Summer for at least a few of the days. In the shorter term, some dense fog may be around first thing Monday morning as conditions in the early morning hours will be perfect for its formation (clear, calm, air becoming saturated as the low temperature meets the dew point).

Forecast for southeastern New England…

OVERNIGHT: Areas of dense fog. Lows middle 40s to lower 50s, coolest inland valleys. Wind calm.

MONDAY: Areas of dense fog and low clouds into mid morning. Mostly sunny midday on. Highs 65-70. Wind E under 10 MPH.

MONDAY NIGHT: Patchy low clouds and fog especially valleys otherwise mostly clear. Lows upper 40s to middle 50s. Wind light variable.

TUESDAY: Mostly sunny. Highs 75-80, closer to 70 immediate coast. Wind variable up to 10 MPH with coastal sea breezes.

WEDNESDAY: Mostly sunny. Low 56. High 84, cooler coast.

THURSDAY: Mostly sunny. Low 58. High 88, cooler coast.

FRIDAY: Partly cloudy. Low 58. High 81, cooler coast.

SATURDAY: Mostly sunny. Low 55. High 79, cooler South Coast.

SUNDAY: Partly sunny. Scattered showers. Low 60. High 77, cooler South Coast.

Sunday AM Update


Very few changes but they are significant.

1) Missed the fog in the forecast. My bad. Should have seen that coming with the calm/clear air last evening and the dewpoint and temp set to meet. As of this writing it’s vanishing quickly with the low clouds soon to follow. Fog-gonnit!!!

2) After all, storm staying offshore.

Full discussion later with The Week Ahead. Quick forecast for now.

TODAY: Morning fog and low clouds in east central MA and southern NH burn off. Otherwise mostly sunny but some high and middle cloud patches Cape Cod and SE MA. Highs in the 60s. Wind E up to 10 MPH.

TONIGHT: Variable high and patchy middle clouds especially eastern MA and coastal NH. Patchy fog in valleys/swamps/bogs, not as widespread as early today. Lows middle 40s to lower 50s. Wind E under 10 MPH.

MONDAY: Variable high and middle clouds far eastern MA/NH especially Cape Cod. Sunshine still plentiful most areas. Highs in the 60s. Wind NE 5-15 MPH.

FRIDAY: Partly cloudy. Low 50. High 71.

SATURDAY: Mostly sunny. Low 51. High 75.

Squeezing It In


Though the weather hasn’t really been too bad the last few days, we have had to contend with some cloudy periods courtesy low pressure in the Canadian Maritimes. Bands of low level moisture rotating around the circulation have caused this to happen. As of the middle of Friday afternoon we are finally seeing a more genuine push of drier air work down from the north and northeast, and this should push these clouds out once and for all (from this low). This will set us up for a great end-of-September weekend. But we are squeezing it in, because another low pressure area will be getting its act together over the ocean to the southeast of New England during the weekend, and is expected to move north northwestward, coming close enough to bring wind and some rain to southeastern New England as early as Sunday night, and more likely for much of Monday. The movement of this storm will likely lead to some large ocean swells and some coastal flooding problems (though not likely major). This will be watched. So, September will end on a stormy note. But as October gets underway, it looks like a stretch of fair and warmer weather will arrive.

Updated forecast for southeastern New England (southern NH, eastern MA, and RI)…

TONIGHT: Clear. Lows near 40 inland valleys to near 50 coastal and urban areas. Calm.

SATURDAY: Sunny. Highs 70-75, upper 60s coastal areas. Wind E up to 10 MPH.

SATURDAY NIGHT: Clear. Lows in the 40s. Wind light variable.

SUNDAY: Sunny. Highs 70-75, again some 60s coast. Wind E to SE 5-15 MPH.

SUNDAY NIGHT:  Increasing clouds. Lows around 50. Wind SE to E 10-20 MPH.

MONDAY: Overcast. Periods of rain. Highs 60-65. Wind E to NE 15-30 MPH and gusty.

TUESDAY: Partly cloudy. Low 47. High 70.

WEDNESDAY: Mostly sunny. Low 50. High 73.

THURSDAY: Mostly sunny. Low 53. High 76.

FRIDAY: Partly cloudy. Low 56. High 79.



The low pressure area in the Canadian Maritimes that has now become close enough to throw periodic cloudiness into the region will be instrumental and reducing a future storm threat. The Maritimes low will continue to toss areas of clouds into southeastern New England through Friday before the blocking pattern in the atmosphere relaxes enough to allow it to move to the east and let go of this area. But the fact that it lingered longer than originally expected will be instrumental in keeping a new low pressure area from developing fully and moving too close late in the weekend and early next week. Indications are that this new system will be far enough offshore to keep direct impact away from the region. A high pressure ridge in the Midwest and Great Lakes will nudge eastward and result in a very nice weekend. The low pressure area offshore by Monday will still have to be watched. Some cloudiness may result but will lean away from precipitation making it into the region for now.

So Close Yet So Fair


Upper level low pressure over the Canadian Maritimes is part of a duo of weather systems keeping southeastern New England in a great weather pattern. The other part is a high pressure ridge to the west of New England. This ridge will eventually slide to the east and become completely dominant, but through Wednesday, the upper low will be almost a little too close for comfort. It will spin some moisture down across Maine and just offshore of NH and MA in the form of clouds and even some light rain. But I expect all the rain to stay offshore of NH and MA, with only some cloudiness coming down across the region mainly Tuesday night and early Wednesday. Otherwise, expect great weather to continue, still a little on the cool side into mid week before a moderating trend gets underway. This pattern is good through the weekend. By the start of next week, we may need to worry a little about low pressure to the south of New England, which may move northward, putting an end to the long stretch of great weather. But that’s far away, and not a worry for now.

The Week Ahead


Too easy. Low pressure over the Canadian Maritimes. High pressure inching from from the Midwest toward the East Coast. This is a setup for a perfect week of weather. There may be some clouds spinning in around the upper low to the east from time to time, and a cool start to the week will be replaced by milder air. We’re going to pay for this eventually. In the mean time, enjoy!

Sunday Morning Update


Here comes the front! The rain arrived in the pre-dawn hours in most of the southern NH, eastern MA, and RI region, with a few showers leading the main area. This area is just making it onto Cape Cod as of 7:30AM, and of course will end there later (early afternoon). Everywhere else, the rain will be ending from west to east by late in the morning. This afternoon will see a quick transition back to the very nice weather we have been experiencing. Though there may be some additional passing clouds later today as a gusty wind develops, think of this as the delivery of the very nice air mass that will hang around, courtesy high pressure, for much of if not all of the coming week (more details tonight on The Week Ahead post). For now a quick updated forecast…

TODAY: Rain exits southern NH, RI, and eastern MA by late morning but lingers on Cape Cod until very early afternoon. Clearing west to east following with sunshine dominating much of the afternoon though some additional passing clouds possible later in the day. Highs around 70, holding in 60s most areas. Wind SW shifting to W 5-15 MPH, then NW, increasing to 10-20 MPH with higher gusts later.

TONIGHT: Partly cloudy to clear. Lows 45-50 except lower 50s urban centers & Cape Cod. Wind NW 10-20 MPH.

MONDAY: Mostly sunny to partly cloudy. Highs 60-65. Wind NW 10-20 MPH and gusty.

TUESDAY THROUGH SATURDAY: Mostly clear nights and mostly sunny days expected. Overnight lows upper 30s to upper 40s early in the period, middle 40s to lower 50s later. Daytime highs 60s Tuesday, middle 60s-lower 70s Wednesday, upper 60s-70s thereafter.

Weekend Hiccup


A cold front will be crossing southeastern New England Saturday night and the first half of Sunday, and a weak wave of low pressure may slow the front’s progress briefly early Sunday, otherwise that will be a hiccup in a weekend that starts out and ends up fine.

Next week, another sprawling high pressure area will arrive and stay for a while, keeping any storminess away. A cool start to the week will be followed by a warming trend.

Updated forecast for southeastern New England (southern NH, eastern MA, and RI)…

THIS EVENING: Clear. Temperatures cool into the 60s. Wind S 5-15 MPH.

OVERNIGHT: Areas of low clouds. Lows 55-60. Wind S 5-15 MPH.

Dry Days


High pressure cruises across the US Northeast today then sinks southeast of the region Wednesday into late week. We in southeastern New England start out with a chilly day Tuesday, with the first frost occurring Tuesday night in many areas outside of urban centers and away from the coast. Moderation occurs from mid week into late week. Sunshine will dominate during the days – some very nice weather. Looking ahead to the weekend: Looks mild with a fair start and a shower threat following as a cold front moves into the region.
