Think about it. :)


Here’s what’s up with the weather. The Summertime pattern is here and will continue into next week, despite a cool interruption along the way. But to get there, we have to go through several more warm to hot days. However, Tuesday’s oppressive dew points will be gone for midweek as it is somewhat less humid and not as hot, but still quite warm. By Thursday night and Friday, the humidity will return as high pressure which moves in behind a cold front Wednesday slides offshore by then. The next front will approach this coming weekend, but at this point the timing of this front is uncertain. I have been leaning toward a slower timing, and continue to do this. This scenario would mean a hot/humid Saturday but a thunderstorm threat potentially for late day or night, and an unsettled day with cooling air for Sunday. If things move along enough, we may enjoy a cool/dry day Monday before another warm-up ensues.


OVERNIGHT: Clouds return west to east. Scattered showers and a risk of a thunderstorm northern MA and southern NH after midnight. Isolated showers and a slight risk of a thunderstorm southern MA to northern RI after 2AM. Most areas will see no showers/storms. Humid. Lows 66-72. Wind SW 5-15 MPH.

WEDNESDAY: Lots of clouds to start, then turning mostly sunny. Less humid. Highs in the 80s, some upper 70s Cape Cod. Wind W 5-15 MPH.

WEDNESDAY NIGHT: Clear. Lows 58-66. Wind light W.

THURSDAY: Mostly sunny. Highs 77-85. Wind W to SW 5-15 MPH.

FRIDAY: Mostly sunny. Low 66. High 89.

SATURDAY: Partly cloudy. Risk of t-storms late. Low 68. High 91, cooler South Coast.

SUNDAY: Mostly cloudy. Low 65. High 82.

MONDAY: Partly cloudy. Low 55. High 70.

TUESDAY: Mostly sunny. Low 55. High 75.

Enter Summer?


So it’s September. The first month of Meteorological Autumn. Those first really crisp days and chilly nights are here, right? Wrong! It’s still Summer, and the pattern reflects this. Despite the fact that a cold front slid into the region late Sunday, it’s not doing a whole lot of cool/dry air delivery, and in fact it’s really just washing out as upper level high pressure remains dominant, and will do so through most of this week. A southwesterly surface flow will allow heat and humidity to gain full control Tuesday, but another cold front will try to cut into this with a shower and thunderstorm risk in the afternoon and evening. Slightly drier air will arrive Wednesday, which will still be a warm day, as will Thursday. And as we head toward the end of the week, it still remain warm to very warm, with humidity returning again Friday into Saturday. A stronger cold front may move through later in the weekend with showers and thunderstorms. Timing of this is uncertain this far in advance, but for now I’m going to lean toward a slower timing with impact more Sunday versus Saturday.


THROUGH SUNSET: Partly cloudy. Isolated showers and brief thunderstorms RI and southeastern MA. Humid. Temperature falling through the 70s South Coast, 80s to upper 70s elsewhere. Wind light W but gusty and variable around any showers/storms.

OVERNIGHT: Partly cloudy. Patchy fog mainly inland valleys. Humid. Lows 60-69. Wind SW under 10 MPH.

TUESDAY: Partly cloudy and hazy. Isolated to scattered showers and thunderstorms midday through evening. Humid. Highs upper 70s South Coast through Cape Cod, 80s elsewhere with a few locations possibly reaching 90. Wind SW 5-15 MPH.

TUESDAY NIGHT: Variably cloudy. Scattered showers and thunderstorms diminishing. Muggy. Lows in the 60s. Wind light SW to W.

WEDNESDAY: Mostly sunny to partly cloudy. Less humid. Highs in the 80s, some 70s Cape Cod. Wind W 5-15 MPH.

THURSDAY: Mostly sunny. Low 63. High 84.

FRIDAY: Partly cloudy. Low 67. High 88.

SATURDAY: Partly sunny. Low 68. High 89.

SUNDAY: Variably cloudy. Scattered showers/thunderstorms. Low 68. High 82.

MONDAY: Mostly sunny. Low 66. High 80.

Labor Day Weekend


The focus of this post will be on the weather forecast for the Labor Day Weekend (Saturday & Sunday August 30 & 31 as well as Monday September 1). But of course there will be a look further into the first week of September.

Overall pattern is warm, though a cooler air mass is currently over the region and will hang in place through Saturday morning before warmer air arrives from the southwest. Saturday itself will dawn quite chilly by standards of the end of August. But high pressure will be in the process of sinking to the south of New England while a weak warm front slides through, producing only some high cloudiness. But it will take quite a while for humidity to start increasing, so after the chilly start you will notice it warming up somewhat on Saturday but remaining dry. By Saturday night and especially Sunday, we’ll get into a stronger southwesterly flow of warm to very warm, more humid air. At the same time, a cold front will be approaching from the northwest and will get closer by Sunday night. At this time it looks like shower and thunderstorm activity with this front will hang back well northwest of the Boston area over western MA and CT, VT and western to central NH and into parts of Maine by late in the day into the evening. In the overnight hours of Sunday night / early Monday this activity will press to the east and cross the main WHW forecast area. Most of it should be moving offshore by early Monday as the front does the same. However the front will be weakening and there is no big push of dry air behind it for Labor Day, which will still be somewhat muggy with a pop up shower or storm possible anywhere in the afternoon but favoring southern MA and RI. So all in all, the weekend will be quite decent.

Looking ahead, we will remain under a flat ridge of upper level high pressure while the jet stream tries to send a couple fronts across the Upper Midwest, Great Lakes, and Northeast Tuesday-Friday. None of these fronts look particularly strong.


TONIGHT: Mostly clear to partly cloudy with some high clouds coming in from the NW. Lows 45-50 inland valleys, 50s elsewhere. Wind light variable.

SATURDAY: Partly cloudy to mostly sunny with some additional high clouds at times. Highs 75-82, coolest coast. Wind light SE to S.

SATURDAY NIGHT: Variable high clouds. Increasingly humid. Lows in the 60s. Wind SW 5-15 MPH.

SUNDAY: Variable clouds at all levels but mainly high & mid level allowing episodes of sun. Humid. Highs 75-80  South Coast / Cap;e Cod, 80s elsewhere, may touch 90 inland. Wind SW 10-20 MPH with higher gusts.

SUNDAY NIGHT: Mostly cloudy. Scattered to general showers and thunderstorms moving across the region from west to east mainly overnight. Humid. Lows 65-70. Wind SW 5-15 MPH but with higher gusts.

MONDAY – LABOR DAY: Variably cloudy. Lingering showers Cape Cod early. Isolated to scattered afternoon showers or thunderstorms possible afternoon, especially along and south of the Mass Pike. Humid. Highs 77-86, coolest Cape Cod. Wind W 5-15 MPH.

TUESDAY: Variably cloudy. Scattered showers/thunderstorms possible mainly at night. Low 65. High 82.

WEDNESDAY: Partly cloudy. Low 66. High 85.

THURSDAY: Partly cloudy. Low 67. High 88.

FRIDAY: Partly sunny. Low 66. High 85.

2 Nice


A cold front moved through southern New England late Wednesday, responsible for a few showers and thunderstorms after a very warm to hot, somewhat humid day. Now high pressure will dominate with mild and drier air for 2 very nice late Summer days today and Friday.

The Labor Day Weekend will feature increasing warmth and humidity Saturday and Sunday, with Sunday featuring a risk of a few showers and storms, similar to Wednesday, as another front approaches. This front will bring a better chance of showers/storms for the Labor Day holiday itself on Monday, and may linger into Tuesday as it runs out of gas over the region. High pressure starts to rebuild on Wednesday next week but this time without the push of drier and cooler air as we will be in a more humid and warm pattern.


TODAY: Mostly sunny. Highs 75-80. Wind NW 5-15 MPH.

TONIGHT: Mostly clear. Lows 50s inland, lower 60s coast. Wind light NW to N.

FRIDAY: Mostly sunny. Highs  70-75. Wind light N shifting to E.

SATURDAY: Partly cloudy. Low 58. High 82.

SUNDAY: Partly sunny. Isolated PM t-storms. Low 63. High 86.

MONDAY- LABOR DAY: Mostly cloudy. Scattered showers/t-storms. Low 66. High 79.

TUESDAY: Variably cloudy. Isolated showers. Low 64. High 80.

WEDNESDAY: Partly cloudy. Low 64. High 84.

1 Hot One


Hot days have been hard to come by in Summer 2014, but Wednesday will be one for much of the southeastern New England region. It won’t be middle 90s hot, but more like around 90 hot, which is about the limit it seems this season. This will be accomplished with high pressure overhead and to the south in the upper levels, and to the south at the surface, also with a cold front approaching from the northwest, increasing the southwesterly air flow over the region. This front, working with moderate humidity, may trigger a few showers and thunderstorms Wednesday afternoon and evening but I do not expect them to be widespread. Favored areas for development is interior NH and MA and down to parts of RI as well. But even though the front will not be overly productive, it will send a push of cooler and less humid air in for Thursday. At about the same time, Hurricane Cristobal will be passing several hundred miles southeast of New England. The only thing we will hear from that is some increased ocean swells Friday into the holiday weekend. During this time, high pressure ridging will try to rebuild over the East Coast while another front approaches from the west northwest. It does not look like this front will have too much push to it, but should get into the region during the second half of the weekend (later Sunday and Monday). This will bring an increased chance for showers and some thunderstorms, especially by Monday. This may also linger into Tuesday as the front hangs around along with more humidity again. Though it will warm back up over the weekend proper (Saturday-Sunday), do not expect too much heat. It should cool back slightly Monday-Tuesday.


TONIGHT: Mostly clear. Humid. Lows in the 60s. Wind light S to SW.

WEDNESDAY: Mostly sunny morning. Partly cloudy afternoon. Mostly cloudy evening. Isolated showers and thunderstorms afternoon/evening mainly interior NH/MA to RI. Humid. Highs upper 70s South Coast/Cape Cod, 80s to around 90 elsewhere. SW breeze.

WEDNESDAY NIGHT: Clearing. Less humid. Lows around 60. Wind light W.

THURSDAY: Mostly sunny. Highs 75-80. Wind NW 5-15 MPH.

FRIDAY: Partly cloudy. Low 58. High 81.

SATURDAY: Partly cloudy. Low 61. High 84.

SUNDAY: Partly sunny. Isolated showers/thunderstorms. Low 64. High 83.

MONDAY – LABOR DAY: Mostly cloudy. Scattered showers/thunderstorms. Low 66. High 77.

TUESDAY: Mostly cloudy. Isolated showers/thunderstorms. Low 65. High 80.

Late Summertime


Finally a warm stretch this month. The warmest days will be Tuesday and Wednesday as high pressure as at its most extensive over southeastern New England. A surface cold front will traverse the region from northwest to southeast Wednesday night, but probably lacking any shower and thunderstorm activity (slight chance).  This timing is a little faster than the early Thursday I expected before. This means that Thursday’s weather will be a little less warm and humid than the next 2 days will be. But by late week some of that warmth and humidity will try to return as high pressure again is south and southeast of the region. The next front approaches when we get to Labor Day Weekend and its timing is uncertain. But at this point I believe its will make a run through the area early Sunday, stalling to the south of the region, and allowing a wave of low pressure to approach with a risk of rain for the holiday itself on Monday, which is also the first day of September.

Tropical Storm Cristobal will track north then turn northeast, passing northwest of Bermuda as a minimal hurricane by early Wednesday, before accelerating into the waters southeast to east of the Canadian Maritime Provinces late in the week. Cristobal will have no direct impact on the US East Coast, other than some increased ocean swells late this week.


TONIGHT: Clear. Patchy valley fog. More humid. Lows 60-66. Wind S under 10 MPH.

TUESDAY: Sunny. Humid. Highs 77-83 South Coast, 84-90 elsewhere. Wind S 5-15 MPH.

TUESDAY NIGHT: Mostly clear. Humid. Lows 64-70. Wind SW 5-10 MPH.

WEDNESDAY: Partly cloudy. Slight risk of an isolated shower or thunderstorm late afternoon and evening, mainly interior MA and northern RI. Humid. Highs 78-84 South Coast, 85-91 elsewhere. Wind SW 5-15 MPH.

THURSDAY: Mostly sunny. Low 60. High 82.

FRIDAY: Partly cloudy. Low 62. High 84.

SATURDAY: Partly cloudy. Low 64. High 86.

SUNDAY: Partly sunny. AM shower risk. Low 66. High 82.

MONDAY – LABOR DAY: Increasing clouds. Chance of rain. Low 62. High 78.

The Week Ahead


A week of Summer weather is ahead as we have now seen the pattern shift into a mode that allows an upper level high pressure ridge to build over the eastern US and surface high pressure to sit south of New England. Cristobal, a tropical storm, will organize itself east of the Bahamas through Tuesday then likely strengthen to a hurricane as it moves north then turns northeast between the US East Coast and Bermuda Wednesday through Friday, finally racing toward the North Atlantic waters next weekend. This system, other than tossing some larger ocean swells toward shore mid to late week, will not bother the East Coast. For southern New England, the only real weather systems of any consequence, and that will be minimal, will be a pair of cold fronts that move through early Thursday and again sometime over the early portion of the Labor Day Weekend. Neither of these look like they will produce much more than cloudiness and a few showers.


TONIGHT: Partly cloudy. Lows in the 50-55 inland 55-60 coast. Wind light variable.

MONDAY: Sunny. Highs 75-80 coast, 80-85 inland. Wind light SE.

MONDAY NIGHT: Clear. Patchy ground fog in low elevations. Lows 55-60 inland valleys, 60-65 elsewhere. Wind light S.

TUESDAY: Sunny. Highs 78-83 South Coast, 83-88 elsewhere. Wind light S to SW.

WEDNESDAY: Partly cloudy. Low 66. High 88.

THURSDAY: Partly cloudy. Isolated showers early. Low 66. High 83.

FRIDAY: Partly cloudy. Low 64. High 81, cooler coast.

SATURDAY: Partly sunny. Chance of a shower. Low 64. High 83, cooler coast.

SUNDAY: Partly cloudy. Low 65. High 84, cooler coast.

Pattern Shift


A reconfiguration of the upper level pattern will have a direct impact on the weather here in southern New England starting almost immediately. We have 2 more cooler than normal days for the weekend as the onshore flow continues, but dies off during Sunday as high pressure sinks over the region. This high pressure area will take up residence south of the region next week and as upper level high pressure that has been over Greenland weakens, moves away, and is replaced by upper level low pressure there, this will allow more high pressure ridging in upper levels in the eastern US. This will not be a powerfully strong high, but it will push the jet stream to the north and allow warmer weather. Troughs from the west coming along the jet stream will be weaker and won’t dig into the Northeast as they had been. Also, a tropical system will likely remain offshore of the East Coast as it recurves later in the week. This will also serve to weaken an approaching system from the west so that a hardly noticeable front comes through sometime late in the week, cutting the warm up back briefly before it likely returns again beyond the forecast period… This is a new regime, and it may last a while.


TODAY: Sun mixed with clouds off the ocean. Highs 66-71 coast, 72-77 inland. Wind NE 5-15 MPH.

TONIGHT: Partly cloudy. Lows in the 50s. Wind light NE.

SUNDAY: More sunshine, fewer ocean clouds. Highs 70-75 coast, 75-80 inland. Diminishing NE breeze.

MONDAY: Sunny. Low 58. High 81.

TUESDAY:  Sunny. Low 61. High 83.

WEDNESDAY: Sunny. Low 64. High 86.

THURSDAY: Partly cloudy. Low 68. High 88.

FRIDAY: Partly cloudy. Low 66. High 82.

Damp to Dry


Easterly flow off the Atlantic and a disturbance from the west have combined to make it damp and grey in southeastern New England, but the theme for the next 3 days will be a very slow drying then clearing trend. You won’t notice it much at first as there will be an overcast and scattered showers around through midday today before showers diminish and eventually become isolated to non-existent. A few patches of drizzle and fog are also possible in coastal areas. Clouds hang on tonight but during tomorrow a clearing trend will begin from the northeast as drier air slides down thanks to high pressure which starts a southward sinking. There will still be some areas of low clouds off the ocean at times especially in coastal areas from Boston south Saturday to early Sunday but these will be diminishing and should vanish by later Sunday morning, leaving the region sunny by the end of the weekend. It still remain cooler than normal through the weekend, however.

The first half of next week, however, will be a different story as high pressure is finally located to the south for a change, and warm air comes in.


TODAY: Cloudy. Scattered showers, diminishing with time. Patchy coastal drizzle/fog. Highs 65-72. Wind E up to 10 MPH.

TONIGHT: Mostly cloudy. Patchy fog. Lows 57-64. Wind NE up to 10 MPH.

SATURDAY: Mostly cloudy to partly sunny. Highs 68-75. Wind NE 5-15 MPH.

SATURDAY NIGHT: Partly cloudy. Lows 56-63. Wind NE up to 10 MPH.

SUNDAY: Partly cloudy to mostly sunny. Highs 70-77. Wind variable up to 10 MPH.

MONDAY: Mostly sunny. Low 58. High 77.

TUESDAY: Mostly sunny. Low 61. High 83.

WEDNESDAY: Mostly sunny. Low 63. High 84.

THURSDAY: Partly cloudy. Low 65. High 86.

Quick Update


High pressure centered to the north continues to try to hold off disturbances to the south and west. The one from the west will toss some cloudiness into the area today and Friday as areas of lower clouds also come in from the ocean due to an east to northeast wind. This will keep it on the cool side. High pressure sinks slowly southward during the weekend with less cloudiness eventually, but still on the cool side temperature-wise. By early next week, it will start to feel more like typical late Summer as high pressure sinks even further and ends up centered south of the region for a change.


TODAY: Areas of low clouds and fog this morning underneath lots of middle and higher clouds above, which will persist through the day and limit sun. Highs upper 60s to middle 70s coast to inland. Wind light E.

TONIGHT: Mostly cloudy. Areas of fog. Lows 55-60. Wind light N.

FRIDAY: Mostly cloudy. Highs middle 60s to lower 70s coast to inland. Wind light E to NE.

SATURDAY: Variably cloudy. Low 58. High 70.

SUNDAY: Partly sunny. Low 57. High 72.

MONDAY: Mostly sunny. Low 59. High 77.

TUESDAY: Mostly sunny. Low 61. High 83.

WEDNESDAY: Partly cloudy. Low 62. High 84.
