DAYS 1-5 (MAY 28 – JUNE 1)

The weather is going to be much cooler than it has been recently and on the unsettled side as we head into and through the Memorial Day Weekend. That much has become clear. The little details of the day-to-day weather are being worked out in each forecast update, and it’s coming into focus that it looks like our wettest weather will be tonight and Saturday morning and during the day Sunday. Sunday’s timing is a little faster than what was indicated yesterday. While I’m not ready to declare Monday a “save”, there is still a chance of some shower activity based on what I see now, but we may salvage part of that day with some dry weather and even some sun. Basically, the unsettled weather is going to the the result of two low pressure areas. The first one comes at the region via the Ohio Valley tonight into Saturday, passing just to the south on a frontal boundary sitting there. We’ll have a chilly northeast to east wind during this. Not atypical for late spring, while some of us were at or above 90 just a couple days ago, most of us will be stuck in the 50s, even some upper 40s, during Saturday and Sunday. We get a break in the rain as the first low moves away during Saturday, but a second low pressure area forming on the boundary to the south will then be pulled northward right into New England on Sunday, bringing the rain back. There is still a little bit of conflict among the various computer guidance about how far west this low tracks, with some guidance bringing it far enough west that we get into a more humid southerly air flow for a time Sunday night into Monday, ending that with a round of showers before the wind switches to north, while other guidance keeps that low center further east and keeps us on its cooler side, but also pulls it out of here quickly enough so that the majority of Memorial Day Monday is dry. At the moment, my leaning is toward the second scenario, but not without some threat of wet weather to at least start the day before potential improvement. There will still be some fine-tuning needed for this forecast. By Tuesday, high pressure will be offshore to the southeast of New England and we’ll see immediate results in the form of warmer weather to welcome June.

TODAY: Increasing clouds. Rain arrives west to east late afternoon / evening. Highs 60-67. Wind NE to E 5-15 MPH, gusts around 20 MPH.

TONIGHT: Overcast. Rain likely. Areas of fog. Lows 41-48. Wind E 5-15 MPH, gusts around 20 MPH.

SATURDAY: Cloudy. Rain tapering to drizzle then ending by late morning. Highs 48-55. Wind E 5-15 MPH, gusts around 20 MPH.

SATURDAY NIGHT: Mostly cloudy. Lows 41-48. Wind NE up to 10 MPH.

SUNDAY: Cloudy. Periods of rain returning south to north in the morning. Areas of fog. Highs 50-57. Wind E 5-15 MPH, higher gusts possible.

SUNDAY NIGHT: Cloudy. Periods of rain. Areas of fog and drizzle. Lows 43-50. Wind variable up to 10 MPH.

MONDAY (MEMORIAL DAY): Mostly cloudy with a chance of showers in the morning. Partly sunny in the afternoon. Highs 60-67. Wind NE to N 5-15 MPH.

MONDAY NIGHT: Partly cloudy. Areas of fog possible. Lows 50-57. Wind variable up to 10 MPH.

TUESDAY: Partly sunny. Highs 71-78. Wind SW 5-15 MPH.

DAYS 7-10 (JUNE 2-6)

Seasonably warm, more humid, and episodes of isolated to scattered showers/thunderstorms with the general pattern likely to feature high pressure offshore, high pressure in Canada, and a weak boundary nearby. An intrusion of cooler air is possible around June 4-5, but not certain.

DAYS 11-15 (JUNE 7-11)

Overall idea right now is similar pattern will continue.

C-19 Chat Post – May 28 2021

DAYS 1-6 (MAY 27-31)

Suddenly we’re in one of those periods of time where forecast confidence takes a hit, even in the short term. It happens, and there’s not much a forecaster can do about it, other than re-evaluate and try again each update! Yes we already had some uncertainty about the upcoming weekend with conflicting guidance which then suddenly reversed roles and now look a bit more in agreement. But just yesterday, last evening / night specifically, many of us, myself included, were expecting a broken line of showers and storms, heaviest to the northwest, struggling to touch any areas south of Boston. What we got was a much more widespread rainfall event for a good portion of the region. Yes, some areas still were missed, but just here at home, for example, while our thunderstorms were not the type you’re going to remember, we ended up with several hours of beneficial rainfall, which might have made the forecast look bad, but was beneficial for our deficit and cleaning out the air and washing off surfaces of the abundant pollen that had been about. And now we move on, looking ahead through the Memorial Day Weekend, which today looks a little less “nice” than I had been leaning. The forecast idea is basically the same today and tomorrow, with high pressure moving in (though staying north) today with drying, still warm but no longer hot air, and generally nice weather. Much cooler air arrives for Friday and may be around for most of if not the entire Memorial Day Weekend while a string of low pressure areas are close enough to plague the region with occasional wet weather. Even at this point the details are still somewhat fuzzy, but the forecast below will reflect a little “less dry” outlook than what it had been doing previously… And who knows, this may look different yet again tomorrow. I’m not as confident as I’d like to be right now!

TODAY: Some early clouds, then mostly sunny. Drying air. Highs 77-84. Wind NW 5-15 MPH.

TONIGHT: Mostly clear. Lows 51-58. Wind N under 10 MPH.

FRIDAY: Increasing clouds. Chance of rain by late in the day. Highs 62-69. Wind NE up to 10 MPH.

FRIDAY NIGHT: Cloudy. Periods of rain. Lows 48-55. Wind E 5-15 MPH.

SATURDAY: Cloudy with period of rain and drizzle in the morning. Mostly cloudy with a chance of rain in the afternoon. Highs 55-62. Wind NE 10-20 MPH.

SATURDAY NIGHT: Mostly cloudy. Chance of rain especially eastern and southern areas. Lows 45-52. Wind NE 5-15 MPH.

SUNDAY: Mostly cloudy. Chance of rain especially eastern and southern areas. Highs 56-63. Wind NE 5-15 MPH.

SUNDAY NIGHT: Mostly cloudy. Chance of rain especially eastern and southern areas. Lows 46-53. Wind NE 5-15 MPH.

MONDAY (MEMORIAL DAY): Mostly cloudy. Chance of rain in the morning. Highs 60-67. Wind NE to N 5-15 MPH.

DAYS 7-10 (JUNE 1-5)

The first few days of June are expected to feature a return to seasonable warmth and slightly higher humidity as a couple disturbances move through the region, but with limited chances for showers and a few thunderstorms. This may be followed by a shot of cooler air from Canada at the end of the period but very low confidence here.

DAYS 11-15 (JUNE 6-10)

Low confidence but indications of a weak boundary in the region, cool Canadian air to the north, warmer and more humid air to the south. Not sure which will dominate just yet, but usually this set up leads to occasionally showery weather.

C-19 Chat Post – May 27 2021

DAYS 1-6 (MAY 26-31)

A one-day shot of heat and higher humidity today as high pressure sits offshore and a cold front approaches from the west. The timing of this front and its associated moisture means the shower and thunderstorm threat from it will hold off until about 6 p.m. or later for the region. The greatest threat for storms both in coverage and intensity, as far as the WHW forecast area goes, will be southwestern and south central NH and north central MA, or areas that have little or no stabilizing influence from a southwest wind, which at this time of year is passing over relatively cool ocean water on its way into New England. This tends to stabilize the air and make it more difficult to develop storms, or to sustain storms that already exist and are moving into these areas. Where the storms do occur, there is a threat of damaging wind gusts, which includes a very small risk of a small tornado should any of the storms be isolated and take on super cell characteristics. Again, this is a low, but not zero, probability so we should pay attention. Otherwise, the typical threats of brief heavy rain, possible small hail, and lightning will be present with any storms. Again, not a widespread event by any stretch, as most people will see activity far less than the maximum potential. Once we are by this threat, another high pressure area moves in for a nice Thursday, warm but dry. As high pressure builds across eastern Canada Friday, a low pressure disturbance will make a run at New England, the brunt of it passing south of the region Friday night and early Saturday, but close enough to put some rainfall into the region at least for several hours. The high to the north will be strong enough to push this away Saturday, which may start wet in eastern and southern areas but will dry out, and be quite cool. Sunday looks dry with only a tiny bit of temperature moderation as a general easterly air flow will continue off the still-cool Atlantic waters. Since this is also the long Memorial Day Weekend, we’ll look at Monday in this section, and it looks like the high pressure area will continue to hold with fair weather, but the center of the high may slip east enough for a more southerly air flow which will allow a bit more warming.

TODAY: Partly cloudy early, then mostly sunny before clouds return late, however clouds may dominate much of the day along the South Coast. Highs ranging widely from 65-72 South Coast with coolest Cape Cod area to 85-92 most areas with a sharp gradient in between these zones. Dew point rising to the middle 60s. Wind SW 10-20 MPH, higher gusts possible.

TONIGHT: Mostly cloudy with a fair to good chance of showers and thunderstorms north and west of Boston early through mid evening and a fair to slight chance of showers and possibly a thunderstorm Boston southward mid to late evening. Clearing overnight. Lows 52-59. Humid evening, drying overnight with dew point falling from the 60s to the 40s. Wind SW 5-15 MPH shifting to NW but may be variable with locally moderate to strong gusts around any showers/storms.

THURSDAY: Mostly sunny. Highs 77-84. Wind NW 5-15 MPH.

THURSDAY NIGHT: Mostly clear. Lows 51-58. Wind N under 10 MPH.

FRIDAY: Increasing clouds. Chance of rain by late in the day. Highs 62-69. Wind NE up to 10 MPH.

FRIDAY NIGHT: Cloudy. Periods of rain. Lows 48-55. Wind E 5-15 MPH.

SATURDAY: Cloudy with a chance of rain or drizzle to start, then a sun/cloud mix. Highs 55-62. Wind NE 10-20 MPH.

SATURDAY NIGHT: Partly cloudy. Lows 47-54. Wind NE 5-15 MPH.

SUNDAY: Partly cloudy. Highs 60-67, coolest coast. Wind E 5-15 MPH.

SUNDAY NIGHT: Mostly clear. Lows 46-53. Wind SE up to 10 MPH.

MONDAY (MEMORIAL DAY): Mostly sunny. Highs 68-75. Wind S 5-15 MPH.

DAYS 7-10 (JUNE 1-4)

The first few days of June are expected to feature seasonable warmth and slightly higher humidity as a couple disturbances move through the region, but with limited chances for showers and a few thunderstorms. This may be followed by a shot of cooler air from Canada at the end of the period but I’ve low confidence on the timing.

DAYS 11-15 (JUNE 5-9)

Warmer air may try to come back early in the period with a shower threat. After that we may be near the border of air masses with additional shower threats but no signs of any widespread beneficial rainfall at this time, and no extreme temperatures.

C-19 Chat Post – May 26 2021

DAYS 1-5 (MAY 25-29)

The Canadian high pressure area that brought us a cool and breezy day yesterday is now to the south of the region and the return flow arrives with a warmer southwesterly wind today, continuing into Wednesday with the return of heat and higher humidity. A cold front will charge across the region late Wednesday with a shower and thunderstorm threat. Another high pressure area moves toward the region but hangs to the northwest on Thursday, but close enough for drier and slightly cooler weather. The cooling trend will continue later in the week but there will be a wet weather threat later Friday to early Saturday as low pressure passes south of the region, but probably close enough to involve us in its moisture envelope…

TODAY: Partly cloudy. Highs 68-73 South Coast, 74-79 elsewhere. Wind SW 10-20 MPH.

TONIGHT: Variably cloudy. Chance of rain showers. Lows 58-65. Increasingly humid with dew point rising toward 60. Wind SW 5-15 MPH with higher gusts.

WEDNESDAY: Partly sunny. Chance of late-day showers/thunderstorms. Humid – dew point over 60. Highs 85-92 except cooler South Coast. Wind SW 10-20 MPH with higher gusts.

WEDNESDAY NIGHT: Mostly cloudy with a chance of showers/thunderstorms early, then clearing. Lows 52-59. Wind shifting to NW 5-15 MPH, higher gusts.

THURSDAY: Mostly sunny. Highs 77-84. Wind NW 5-15 MPH.

THURSDAY NIGHT: Mostly clear. Lows 51-58. Wind N under 10 MPH.

FRIDAY: Increasing clouds. Chance of rain by late in the day. Highs 62-69. Wind NE up to 10 MPH.

FRIDAY NIGHT: Cloudy. Periods of rain. Lows 48-55. Wind E 5-15 MPH.

SATURDAY: Cloudy with a chance of rain or drizzle to start, then clearing. Highs 55-62. Wind NE to N 10-20 MPH.

DAYS 6-10 (MAY 30 – JUNE 3)

High pressure is expected to dominate the weather for the remainder of the Memorial Day Weekend (May 30-31) with dry weather and below to near normal temperatures . A series of disturbances will move through the region during the first few days of June with a couple opportunities for unsettled weather, but warmer and somewhat more humid conditions.

DAYS 11-15 (JUNE 4-8)

A frontal boundary may be hanging around the region with additional opportunities for showery weather. No extreme temperatures are indicated.

C-19 Chat Post – May 25 2021

DAYS 1-5 (MAY 24-28)

The last “work week” of May has arrived and we’ll see a cooler week overall than the previous week was. We do remain in a fairly dry pattern, though a couple rain chances are there, generally surrounding air mass changes. We’ll see two distinctive air mass changes surrounding a spike of heat and humidity on Wednesday. But first, Canadian high pressure provides us with a pleasant day to start the week today. As this high slips to the south, a warm front will approach the region later Tuesday. We’ll already have warmed up from today’s temperatures by tomorrow just from return flow on the back side of the high, but the warm front will bring more cloudiness and eventually a chance of passing showers sometime Tuesday night to the early hours of Wednesday before it passes, and opens the door for the brief return of heat and humidity. A cold front will cross the region Wednesday evening, likely accompanied by some showers and thunderstorms, and definitely followed by somewhat cooler and drier air for Thursday as another Canadian high builds north of the Great Lakes but extends eastward enough to push the heat and humidity away. However, that frontal boundary will be fairly close by still and with the high pressure area taking its time moving any further southward initially, the door is open for a disturbance to move up into the area on Friday with clouds and possible showers. I’m not highly confident that this scenario takes place yet, however, but it’s possible.

TODAY: Sun and passing clouds.. Highs 62-67 coast, 68-73 inland. Wind NE 5-15 MPH, diminishing and becoming variable.

TONIGHT: Mostly clear to partly cloudy. Lows 47-54. Wind variable to SW increasing to 5-15 MPH with higher gusts overnight.

TUESDAY: Partly sunny. Highs 68-73 South Coast, 74-79 elsewhere. Wind SW 10-20 MPH.

TUESDAY NIGHT: Variably cloudy. Chance of rain showers. Lows 58-65. Increasingly humid with dew point rising toward 60. Wind SW 5-15 MPH with higher gusts.

WEDNESDAY: Partly sunny. Chance of late-day showers/thunderstorms. Humid – dew point over 60. Highs 85-92 except cooler South Coast. Wind SW 10-20 MPH with higher gusts.

WEDNESDAY NIGHT: Mostly cloudy with a chance of showers/thunderstorms early, then clearing. Lows 50-57. Wind shifting to NW 5-15 MPH, higher gusts.

THURSDAY: Mostly sunny. Highs 75-82. Wind NW 5-15 MPH.

THURSDAY NIGHT: Partly cloudy. Lows 52-59. Wind N 5-15 MPH becoming variable.

FRIDAY: Mostly cloudy. Chance of showers. Highs 61-68. Wind variable to SE 5-15 MPH.

DAYS 6-10 (MAY 29 – JUNE 2)

The computer guidance for the May 29-31 Memorial Day Weekend continues to “disagree” on the solution and resultant weather. The scenario I am leaning toward right now is dry weather all 3 days with Canadian high pressure in control, but with its center to the north, at least through Sunday, with a general easterly air flow and near to slightly below normal temperatures, but it may not be as cool as it could have been since the ocean temperatures are running on the milder side of normal and probably won’t change by then. The atmosphere may warm a bit further, depending on the position of the high pressure, by Memorial Day itself on May 31. Confidence is still not super-high on this outlook so adjustments may occur. Looking ahead to the first couple days of June, a bit warmer and a bit more humid, maybe a shower threat at some point as a disturbance approaches from the west after the high pressure area gives way.

DAYS 11-15 (JUNE 3-7)

A frontal boundary may be hanging around the region with a few opportunities for showery weather. We need rain as our wetter pattern in April and the start of May has vanished on us and we’re trending back into abnormally dry to near drought again with each passing day without widespread significant rainfall.

C-19 Chat Post – May 24 2021

DAYS 1-5 (MAY 23-27)

The feel of summer will be in full force today, but this is not really that unusual for late May, as we tend to get shots of summertime heat and a bit of humidity like this on maybe 2 out of 3 years in May across the region. Regardless, this stretch is about to come to an abrupt end tonight after a sharp cold front moves across the region. While the dynamics are not great, they are enough that the front will likely trigger a broken line or at least a line / zone of scattered showers and thunderstorms as it moves across the region tonight. And then in comes a brief but sharp shot of cool air for Monday, delivered by Canadian high pressure. But this won’t last long as the high ends up south of the region by Tuesday and a warm front moves in from the west, bringing clouds, higher humidity, and a shower chance. The warm front’s passage will introduce a shot of hotter and humid weather for Wednesday, which itself won’t last long as another cold front arrives later in the day or at night with a shower and thunderstorm threat, and a return to cooler and drier weather once again for Thursday, but this time not as strong a push of cool air as the one we will see tonight and Monday.

TODAY: Mostly sunny through midday. Variably cloudy with passing showers and thunderstorms possible from north to south across the region during the afternoon. Highs 86-93 except 78-85 South Coast and 70-77 Cape Cod. Wind W 10-20 MPH. Humid – dew point over 60. Wind SW 10-20 MPH but can be variable with locally strong gusts near any storms.

TONIGHT: Clearing. Lows 48-55. Much drier – dew point falling to 40s. Wind NW to N 10-20 MPH.

MONDAY: Sunshine and passing clouds. Highs 62-69, coolest coast. Wind N to NE 10-20 MPH, diminishing late.

MONDAY NIGHT: Partly cloudy. Lows 48-55. Wind variable up to 10 MPH.

TUESDAY: Variably cloudy. Chance of showers. Highs 70-77. Wind W 5-15 MPH.

TUESDAY NIGHT: Partly cloudy. More humid. Lows 60-67. Wind SW 5-15 MPH.

WEDNESDAY: Partly sunny. Chance of late-day showers/thunderstorms. Humid – dew point over 60. Highs 85-92 except cooler South Coast. Wind SW 10-20 MPH.

WEDNESDAY NIGHT: Mostly cloudy with a chance of showers/thunderstorms early, then clearing. Lows 50-57. Wind shifting to NW 5-15 MPH, higher gusts.

THURSDAY: Mostly sunny. Highs 75-82. Wind NW 5-15 MPH.

DAYS 6-10 (MAY 28 – JUNE 1)

There continues to be conflicting guidance regarding the last several days of May, including the May 29-31 Memorial Day Weekend. Continuing with the thought process of increased moisture in the area and a chance of some wet weather May 28, maybe into May 29 before high pressure takes over with drier weather for the balance of the long weekend and possibly through June 1. Still not a very high confidence outlook.

DAYS 11-15 (JUNE 2-6)

Looking for a frontal boundary in the region with more moisture and some wet weather opportunities and a lack of temperature extremes.

C-19 Chat Post – May 23 2021

DAYS 1-5 (MAY 22-26)

This weekend will feature a preview of summer, followed by a reminder on Monday that it is not really summer just yet, followed by a reminder toward the middle of next week that summer is just right around the corner. Fickle. Fitting. Fast-changing. That’s our weather, and it will be on display for you to love, loathe, or just experience, depending on your preference(s). We start today where we have been for a couple days now, on the eastern side of an upper level ridge of high pressure, where the wind above us is blowing from the northwest, but at the surface a general southerly to westerly air flow means higher humidity and very warm to even hot conditions this weekend. With a fair amount of cloud cover much of the time today, the temperature will not reach the levels it would have under a clear sky with full sunshine, but you will notice it becoming rather warm after a modestly mild start, and the most sensitive will notice an uptick in humidity as we go through the day. The northwesterly air flow above us will be transporting yet another disturbance down across New England from Canada, and this, combined with what heating we do get from the sun, will pop a few isolated showers and possibly a thunderstorm this afternoon and early evening. While most areas will likely escape this activity, the few areas that do see it can be visited by a brief downpour but more likely a lighter shower. Bottom line: you probably won’t get wet, but if you do, it won’t last long. Sunday will feature more sunshine but a bit more wind ahead of an approaching cold front which will be heading rapidly southward out of Canada into New England. Before it arrives, many areas will make a run at 90 and some may reach or exceed it for the first time this year. While the dynamics are not there for a widespread thunderstorm outbreak, the front is likely to trigger at least scattered showers and storms, a few of which may be on the strong side. So if you have outdoor plans, pay attention to the sky (and a radar app if you have one), especially during the afternoon. By Sunday night, the front will be exiting via the South Coast and we’ll already be feeling the change to a much cooler air mass, which will be in control of Monday’s weather as high pressure moves in from southeastern Canada. Many areas will be 18 to 25 degrees cooler for high temperature on Monday than they will be on Sunday. But this cool-down will be short-lived, as the same high pressure area that brings the cool air will settle to the south of New England by Tuesday and the return flow around it from the southwest and west will warm us right back up, lasting into Wednesday when we may heat up about as much as we do on Sunday. And another front will approach later Wednesday with a shower and thunderstorm threat, but that being 5 days away I can’t speculate much on that particular event at this point.

TODAY: Variably cloudy. Isolated showers and a slight chance of thunderstorms in the afternoon and early evening. Increasing humidity – dew point approaching 60. Highs 68-75 South Coast, 75-82 southeastern MA not at immediate coast, and 83-90 elsewhere. Wind SE to S up to 10 MPH early, becoming SW 5-15 MPH, but local sea breeze possible.

TONIGHT: Mostly cloudy evening with possible showers. Clearing overnight. Areas of ground fog forming. Lows 58-65. Humid – dew point upper 50s to lower 60s. Wind SW up to 10 MPH.

SUNDAY: Mostly sunny morning-midday. Partly sunny to mostly cloudy with a chance of showers and thunderstorms afternoon. Humid – dew point 60s. Highs 85-92 except 78-85 South Coast and 70-77 Cape Cod. Wind SW 10-20 MPH.

SUNDAY NIGHT: Clearing. Lows 50-57. Much drier – dew point falling to 40s. Wind NW to N 10-20 MPH.

MONDAY: Sunshine and passing clouds. Highs 62-69, coolest coast. Wind N to NE 10-20 MPH, diminishing late.

MONDAY NIGHT: Partly cloudy. Lows 48-55. Wind variable up to 10 MPH.

TUESDAY: Variably cloudy. Chance of showers. Highs 70-77. Wind W 5-15 MPH.

TUESDAY NIGHT: Partly cloudy. More humid. Lows 60-67. Wind SW 5-15 MPH.

WEDNESDAY: Partly sunny. Chance of afternoon showers/thunderstorms. Humid – dew point over 60. Highs 85-92 except cooler South Coast. Wind SW 10-20 MPH.

DAYS 6-10 (MAY 27-31)

High pressure from Canada brings cooler/dry weather May 27. Uncertainly on how the last several days of May play out, including the May 29-31 Memorial Day Weekend. For now thinking we may need to watch for a wave of low pressure bringing some wet weather around May 28-29 then high pressure moving in with drier weather, but this is very low confidence and may look rather different to me just 24 hours from now.

DAYS 11-15 (JUNE 1-5)

Air mass boundary in area the first several day of June with variable temperatures and at least a couple opportunities for showers/thunderstorms. No early indications of any extreme temperatures.

C-19 Chat Post – May 22 2021

DAYS 1-5 (MAY 21-25)

Upper level high pressure dominates and will continue to do so through the weekend, but this doesn’t automatically mean clear skies, as you can see this morning as the sky is filled with much cloudiness from a disturbance from Canada. This is because the axis of the upper ridge is to the west and the air above us is blowing from northwest to southeast. We often see moisture and energy from the other side of the ridge, or the trough to its west, ride up and over the ridge and down its eastern side. This will continue to be the case through the weekend, which will certainly be no wash-out, but will carry opportunities to see showers (and even thunderstorms by Sunday) as a series of disturbances and finally a stronger cold front comes through. But before that cold front arrives and despite the northwesterly flow aloft, at the surface the dominant air flow is going to be from the southwest, which will work on warming our air up today and bringing the feel of mid summer along with slightly higher humidity for the weekend. Then the cold front will come through, and this sets us up for a dry and cooler Monday as high pressure drops out of Canada. But that high will keep on moving and by Tuesday it’ll be south of the region with warmer air coming back, along with more cloudiness and even another shower threat.

TODAY: Mostly cloudy to partly sunny. Slight chance of a shower mainly north and west of Boston until mid-morning and again late in the day. Highs 68-75 South Coast, 76-83 elsewhere. Wind S 5-15 MPH.

TONIGHT: Variably cloudy. Possible showers. Lows 53-60. Wind SW 5-15 MPH.

SATURDAY: Partly sunny. Isolated to scattered showers and a slight chance of thunderstorms mainly mid afternoon on. More humid, dew point upper 50s to middle 60s. Highs 68-75 South Coast, 75-82 southeastern MA not at immediate coast, and 83-90 elsewhere. Wind SW 5-15 MPH.

SATURDAY NIGHT: Mostly cloudy evening with possible showers. Clearing overnight. Areas of ground fog forming. Lows 58-65. Humid – dew point upper 50s to lower 60s. Wind SW up to 10 MPH.

SUNDAY: Mostly sunny morning-midday. Partly sunny to mostly cloudy with a chance of showers and thunderstorms afternoon. Humid – dew point 60s. Highs 85-92 except 78-85 South Coast and 70-77 Cape Cod. Wind SW 10-20 MPH.

SUNDAY NIGHT: Clearing. Lows 50-57. Much drier – dew point falling to 40s. Wind NW to N 10-20 MPH.

MONDAY: Sunshine and passing clouds. Highs 62-69, coolest coast. Wind N to NE 10-20 MPH, diminishing late.

MONDAY NIGHT: Partly cloudy. Lows 48-55. Wind variable up to 10 MPH.

TUESDAY: Variably cloudy. Chance of showers. Highs 70-77. Wind W 5-15 MPH.

DAYS 6-10 (MAY 26-30)

Early for too many details but a shot of heat possible May 26 with showers/thunderstorms possible, cooler/drier following by May 27 then high pressure may hold over the region with dry weather and a warming trend thereafter.

DAYS 11-15 (MAY 31 – JUNE 4)

Low confidence forecast. High pressure may keep the region dry through May 31 followed by an increase in shower chances sometime in the first several days of June as an air mass boundary may be in the area.
