High pressure north of New England will provide dry weather with no heat in sight through the weekend. The only real “interruption” if you want to call it that may be a period of extensive low cloudiness late Saturday night and Sunday morning as some moisture comes in from the Atlantic with an easterly wind.

Next week, high pressure will start shifting more to the south and finally allowing more southwesterly flow to develop. This will result in a warm-up, the first real sign of this likely being less sunshine Monday as warmer air coming in first aloft creates more cloudiness.  I’m not looking for any major heat next week as wetter topsoil and abundant green vegetation will make it hard to heat up too much.

Forecast for eastern MA, RI, and southeastern NH…

THROUGH SUNSET: Clouds depart Nantucket. Mostly sunny elsewhere. Temperatures ranging from the middle 60s to lower 70s coast to inland will fall back slightly. Wind NE-E 10-15 MPH.

TONIGHT THROUGH SATURDAY: Clear nights, sunny days. Lows in the 50s, coolest interior valleys. Highs 65-75, coolest coast. Wind NE-E under 10 MPH at night, up to 15 MPH during the day.

SATURDAY NIGHT: Low clouds developing. Low 50-55. Wind E under 10 MPH.

SUNDAY: Low clouds slowly dissipating during the morning leading to a sunnier afternoon. High 62-67 coast, 67-72 inland. Wind E 10-15 MPH.

11:13PM

The last of the drizzle, low clouds, and fog will slip out quietly in the early hours of Thursday morning. Dry weather will follow for days on end as high pressure dominates. The high centered to the north means that an air flow from the north to northeast will keep temperatures in check during the next few days as sunshine dominates. By Monday, more clouds will dominate as warm air starts moving in above the ground first, eventually reaching the surface early next week.

Low pressure will bring periods of rain to southern New England today. High pressure will build down from the north  Thursday through the coming weekend, with mainly dry weather but a lack of summer heat as the air will be coming from the Maritimes of Canada and also modified at times by the nearby Atlantic waters.

2:46AM

A little reverse on the title of a recent blog, because this time we have wet weather coming in for a relatively short time during midweek before high pressure returns fair weather to the region late in the week. The wet weather will be caused by a slow-moving front that comes in from the west tonight through Wednesday night, lingering into Thursday, with an area of low pressure forming on it to the south, eventually drifting to east with time.

Forecast for eastern MA, southern NH, and RI…

TODAY: Mostly cloudy. High 66-72, coolest coastal areas. Wind S 5-15 MPH.

SATURDAY: Mostly sunny. Low 57. High 77.

SUNDAY: Mostly sunny. Low 58. High 78.

MONDAY: Sunny. Low 60. High 80.

1:38AM

High pressure noses southward across New England today then slides eastward a little on Tuesday, finally retreating northeastward into southeastern Canada as unsettled weather moves in from the south and west at midweek. High pressure regains control late in the week. This outlook is pretty much unchanged from the previous post.

Forecast for the week ahead for eastern MA, RI, and southeastern NH…

TODAY: Partly cloudy. High from the upper 60s coast to upper 70s well inland. Wind SE up to 10 MPH.

TONIGHT: Partly cloudy. Low from the lower 50s inland valleys to near 60 at the coast. Wind S under 10 MPH.

SUNDAY: Mostly sunny. Low 57. High 75.

4:47PM

The next several days will see a quiet battle of high pressure to the north and low pressure to the south. A weak boundary with a disturbance moving along it has really only been able to produce some clouds across western and southern New England during the day Saturday, but these have battled drier air trying to press in from the north and plenty of sun has been enjoyed in much of the forecast area. This high pressure area will win the battle Sunday through Tuesday, and it will press far enough south so that winds that will be mainly north to east on Sunday will turn more southerly by late Monday and Tuesday. By midweek, low pressure will start to win out for a couple days as a frontal system moves in and provides an avenue to bring some moisture into the region. High pressure will again push the unsettled stuff back to the south at the end of the week.

Updated forecast for eastern MA, southern NH, and RI…

TONIGHT: Variably cloudy. Low ranging from the lower 50s inland valleys to near 60 along the coast and in urban centers. Wind W to NW around 10 MPH.

SUNDAY: Mostly sunny. High from the upper 60s immediate coast to upper 70s well inland. Wind N 5-15 MPH shifting to E.

SUNDAY NIGHT: Mostly clear. Low ranging through the 50s, coolest inland valleys and mildest near the coast. Wind light E to SE.

MONDAY: Sunny. High from 70 immediate coast to 80 well inland. Wind SE 5-15 MPH.

TUESDAY: Mostly sunny. Low 55. High 70 coast to 80 inland.

WEDNESDAY: Partly sunny. Scattered showers/thunderstorms. Low 60. High 75.

THURSDAY: Mostly cloudy. Scattered showers. Low 59. High 73.

FRIDAY: Slow clearing. Low 56. High 75.

SATURDAY: Mostly sunny. Low 58. High 78.

4:44PM

We continue under the influence of low pressure and cold air aloft as more showers and thunderstorms have popped up during the day today. These will fade with the setting sun, only to re-fire tomorrow as the atmosphere continues to be unstable. A pair of weak disturbances will pass across northern New England during the day Saturday then just south of New England Saturday night. At this point, these don’t look like they will have a big impact, perhaps a shower or thunderstorm Saturday night in a few locations. Drier, warmer weather Sunday through early next week will be the result of building high pressure.

Forecast for eastern MA, southern NH, and RI…

TONIGHT: Variably cloudy in the evening with diminishing showers and thunderstorms. Partly cloudy to mostly clear but patchy ground fog forming overnight. Low 50-55. Wind S to SW under 10 MPH.

FRIDAY: Mostly sunny in the morning with any patchy fog dissipating early. Developing clouds leading to scattered showers and thunderstorms in the afternoon. High 70-75, holding in the 60s in a few coastal areas. Wind variable to S up to 10 MPH.

WEDNESDAY: Partly sunny. PM showers and thunderstorms. Low 64. High 83.

THURSDAY: Mostly cloudy. Scattered showers and thunderstorms. Low 66. High 77.

3:51PM

Low pressure will still be in control through Thursday but slight improvement will be showing each day, in the form of less ocean drizzle/showers and more breaks in the clouds. This will allow instability showers and thunderstorms to fire up well inland, however. Once we get by this, it looks like a warmer, drier pattern will take over starting about Friday and lasting into the start of next week.

TUESDAY: Mostly sunny. Low 62. High 83.

12:00AM

Boston MA and Seattle WA will be twins on opposite coasts Monday, both having a high temperature in the lower to middle 50s with wet weather. Boston’s soaker will be caused by continued influence of broad upper level low pressure and a couple of surface lows (one going out south of New England and another one backing down the coast from Maine and joining the other). In addition, minor to moderate coastal flooding is likely around the times of high tide, especially the Monday night high tide which will be astronomically high. The entire circulation will then sink south and east through midweek, and it will take much of the week to finally work out of its influence. The wettest weather of Monday will ease slightly Tuesday then moreso during the Wednesday-Friday period, but as more and more breaks in the clouds take place that will only set the stage for afternoon showers and thunderstorms to develop over inland locations mid to late week. Looking ahead to the weekend, further improvement and a warm-up should take place.

Forecast for southeastern NH, eastern MA, and RI…

OVERNIGHT: Overcast. Periods of drizzle, areas of fog, and a chance of rain toward dawn. Low 50-55. Wind N-NE 10-15 MPH gusting 20-25 MPH.

SUNDAY: Partly cloudy to mostly sunny. Low 61. High 78.

3:30AM

Upper level low pressure will continue to dominate the Northeast well into next week. But a drier slot of air at the surface will provide a little bit of a break for today after yesterday’s very wet and cool day. Some sunshine today will boost temperatures into the 70s but the air will be unstable enough that some showers and thunderstorms may pop up during the afternoon. This brief break will be short lived, as the entire upper level low will shift southeastward and pull the moisture from today back down across southern New England Monday, which will turn out to be a very wet and chilly day. Improvement after this will be very slow heading through midweek.

Forecast for eastern MA, southeastern NH, and RI… (Update as of 11:25AM)

THIS AFTERNOON: Most sun in RI and adjacent MA but more sun trying to work further north and east into eastern MA and southern NH with time, though lots of clouds and a few patches of drizzle continue in these areas for a time. More clouds returning from the west later and a slight chance of a few showers or even an isolated thunderstorm late day. High 72-77 but 60s Cape Cod and Islands. Wind NW 5-15 MPH with higher gusts.

Some of you will get the 2009 reference above. For those who don’t, the weather from Saturday through the middle of  next week will remind you of the weather pattern we had in June (and July) of 2009. But before we get there, what a splendid day today will be. High pressure hanging on will provide bright sun much of the day though some high & mid level clouds will start to move in toward the end of the day from the west, and a few low clouds from the ocean may cross Cape Cod and the Islands. Also an east wind will keep it on the cooler side, especially at the coast, but not so cool that it isn’t enjoyable for most people.

Instead of going into great day by day detail, I’ll just sum up the coming several days this way: Not a great weather pattern, as we probably don’t get enough rain to erase the precipitation deficit, and not great weather for outdoor activities. You can blame this on a blocking pattern (similar to one we see in winter and early spring) that will hold upper level low pressure over the Northeast from this weekend well into next week. It won’t rain all the time, and we may even see a little sun here and there (especially for a while Sunday) but we’ll also see episodes of showers and drizzle, along with below normal temperatures.

5:09PM

Big temperature range across New England this Tuesday afternoon from the upper 50s to the lower 90s (coolest being in coastal Maine and hottest being interior southwestern New England). This, and a cold front approaching from the west, are triggers for thunderstorms. And indeed there have been some firing up during the afternoon, mainly across NY State and parts of VT into NH. A marine layer has held low clouds in for much of the day up until mid afternoon over a large portion of Middlesex and Essex Counties of MA and adjacent NH, but this has eroded away finally. However, this marine layer has been tough to get rid of, and remains in place. This will be a factor in limiting the storm potential for much of eastern MA for this evening. As storms try to  move in this direction, they will likely weaken and eventually fall apart. The warmer and more humid air has made it into parts of southeastern MA away from the immediate shore, but by the time any storms get into this region in the overnight hours, it will have cooled down and the atmosphere will not be too unstable there. So this means that most of the WHW forecast area of southeastern NH, eastern MA, and RI, will not see any severe weather tonight. There will be some chance of storms, however, with the primary window of time being 9PM tonight to about 4AM Wednesday. Any storms may produce heavy rain and of course some lightning.

We still have to get the front to clear the region and another trough on Wednesday, so during the day there will still be some chance of showers and thunderstorms. The final trough will be moving offshore Thursday morning which will set the stage for 2 great days Thursday and Friday as high pressure dominates. Some clouds may return before Friday is done, in advance of the next low pressure system. This is expected to cross the region Saturday with some showers, though at this time it does not look like a widespread rain event. Sunday, we may see a few pop up showers as a cool upper level low crosses New England.

Updated forecast for southeastern NH, eastern MA, and RI…

THROUGH EVENING: Clouds increase. Temperatures ranging from the 60s coastal northeastern MA, NH, and Cape Cod, to the lower 80s southwest of Boston. Wind variable from light onshore near the coast to S-SW around 10 MPH inland areas.

OVERNIGHT: Mostly cloudy. Episodes of showers and thunderstorms, a few possibly heavy. Low 63-68. Wind SW 5-15 MPH may be gusty around any storms.

WEDNESDAY: Partly sunny. Isolated to scattered showers and thunderstorms may occur at any time but are most likely from late morning through late afternoon. High around 80 most areas, holding in the upper 60s to lower 70s where winds come off ocean water. Wind W-SW 5-15 MPH.

WEDNESDAY NIGHT: Partly cloudy. Low from the middle 50s to lower 60s. Wind W 5-15 MPH.

THURSDAY: Partly sunny early, then mostly sunny. High 70-75. Wind NW 5-15 MPH becoming variable.

“They gave their tomorrows for our todays.” Please pause to remember them.

I apologize for the lack of a week ahead post last night. Spent most of the afternoon and evening in NH. This update will cover through next weekend.

The one change the previous forecast will be the lower temperatures for today because of the front still across the area, keeping the 80 degree temperatures that I was anticipating off to the south and west of much of the forecast area. One trade-off is that with a more marine-stabilized layer of air, there is less of a chance of showers and thunderstorms today.

This will not be the case later tonight through Tuesday and into Wednesday, as a slow-moving front will push through the area.

High pressure will bring drier weather Thursday and Friday before another low and frontal system brings a shower threat for the early part of the weekend.

Forecast for eastern MA, RI, and southern NH…

TODAY: Lots of clouds but intervals of sun. Isolated showers and thunderstorms are most likely near 495 in areas mostly south of the Mass Pike to around northern RI. High ranging from the 60s coast to the upper 70s inland areas south of the Mass Pike. Wind variable but often E up to 10 MPH.

TONIGHT THROUGH WEDNESDAY: Mostly cloudy. Episodes of showers and thunderstorms, with the most likely time periods 11PM to 4AM overnight tonight, midday and afternoon Tuesday, morning and early afternoon Wednesday. Lows in the 60s. Highs in the 70s. Wind 5-15 MPH mostly S through Tuesday shifting to W Wednesday.

THURSDAY: Mostly sunny. Low 55. High 73.

FRIDAY: Mostly sunny. Low 52. High 71.

SATURDAY: Mostly cloudy. Chance of showers. Low 58. High 68.

SUNDAY: Partly cloudy. Low 56. High 72.
