DAYS 1-5 (JULY 8-12)

A quick shot of warmth and higher humidity, though not oppressive humidity, precedes the passage of a cold front later today. This front will have limited activity on it, with only a few showers and perhaps a thunderstorm in the area later in the day. That exits during tonight, and high pressure builds in for a beautiful weekend, coolest both days along the coast, warmest inland, but lots of sun and low humidity both days as well. High pressure will move offshore Monday and a southwesterly wind, the “return flow” as it’s known, will usher in warmer but only slightly more humid air. You’ll notice the humidity more so on Tuesday as well as the feel of summer as we make a rare (for this summer so far) run at 90. We’ll also have to watch for a late-day thunderstorm Tuesday as a frontal boundary will be getting closer to the area from the northwest.

TODAY: Variably cloudy. Isolated to scattered showers and a slight chance of a thunderstorm mainly mid to late afternoon. Highs 79-86. Dew point over 60. Wind SW 5-15 MPH.

TONIGHT: Mostly cloudy with a chance of showers early, then clearing. Lows 57-64. Dew point falling to near 50. Wind NW 5-15 MPH.

SATURDAY: Sun and passing clouds. Highs 77-84. Dew point 50s. Wind NW 5-15 MPH shifting to NE.

SATURDAY NIGHT: Mostly clear. Lows 55-62. Dew point under 50. Wind NE under 10 MPH.

SUNDAY: Mostly sunny. Highs 77-84, coolest coast. Dew point near 50. Wind N shifting to E up to 10 MPH.

SUNDAY NIGHT: Mostly clear. Lows 56-63. Dew point near 50. Wind variable up to 10 MPH.

MONDAY: Mostly sunny. Highs 80-87. Dew point near 55. Wind variable up to 10 MPH morning, SW 10-20 MPH afternoon.

MONDAY NIGHT: Mostly clear. Lows 61-68. Dew point nearing 60. Wind SW 5-15 MPH.

TUESDAY: Partly cloudy. A late day shower or thunderstorm is possible. Highs 85-92. Dew point rising through 60s. Wind SW 10-20 MPH.

DAYS 6-10 (JULY 13-17)

A cold front moving through the area July 13 presents a shower and thunderstorm chance with warm air and high humidity in place. High pressure builds in with fair, slightly cooler, and drier weather July 14-16. Next chance of unsettled weather comes at the end of the period.

DAYS 11-15 (JULY 18-22)

Another area of high pressure builds in with cooler, drier weather to start the period, then warmer and increased humidity later in the period when the chance of showers and thunderstorms will return.

DAYS 1-5 (JULY 7-11)

Weak high pressure slides offshore today and sets up a southeasterly air flow, aided by the development of a diurnal sea breeze anyway near the coast, so it will be a mild day but cooler readings will be found at beaches. Occasional clouds will cross the sky with some mid level moisture about. Tonight, a warm front crosses the region with clouds but no precipitation. Friday, a cold front will move across the region, but not arriving until late it will give us a chance to feel a bit more warmth and slightly more humid. Generation of showers and possible thunderstorms will be somewhat limited, so many areas may get through this without seeing any rain at all. The weekend will be spectacular, governed by Canadian high pressure, with plenty of sun both days, fairly light wind, and low humidity. We may see some clouds around early Saturday though to start the weekend off as a result of Friday’s front being a bit sluggish upon its exit. High pressure will retain control of our weather Monday with another nice day expected.

TODAY: Partly sunny. Highs 77-84, coolest coast. Dew point under 60. Wind S-SE up to 10 MPH with a few coastal gusts to 15 MPH.

TONIGHT: Mostly cloudy. Lows 60-67. Dew point under 60. Wind variable To S up to 10 MPH.

FRIDAY: Variably cloudy. Isolated to scattered showers and a slight chance of a thunderstorm. Highs 79-86. Dew point over 60. Wind SW 5-15 MPH.

FRIDAY NIGHT: Mostly cloudy with a chance of showers early, then clearing. Lows 57-64. Dew point falling to near 50. Wind NW 5-15 MPH.

SATURDAY: Sun and passing clouds. Highs 77-84. Dew point 50s. Wind NW 5-15 MPH.

SATURDAY NIGHT: Mostly clear. Lows 55-62. Dew point under 50. Wind N under 10 MPH.

SUNDAY: Mostly sunny. Highs 77-84, coolest coast. Dew point near 50. Wind N shifting to E up to 10 MPH.

SUNDAY NIGHT: Mostly clear. Lows 56-63. Dew point near 50. Wind variable up to 10 MPH.

MONDAY: Mostly sunny. Highs 78-85. Dew point near 55. Wind variable up to 10 MPH with coastal sea breezes.

DAYS 6-10 (JULY 12-16)

A shot of warmth and humidity followed by a shower/thunderstorm chance, then a return to mild/dry weather as the overall weather pattern remains the same.

DAYS 11-15 (JULY 17-21)

High pressure will be in control much of the time. Starting the period on the dry side then increasing the humidity and a slight chance of showers and thunderstorms later.

C-19 Chat Post – 7-7-2022

DAYS 1-5 (JULY 6-10)

A quiet weather pattern will be ours for days to come. High pressure brings fair and warm weather today but with lower humidity and a cooling coastal sea breeze developing. The high moves off to the south and east Thursday and the frontal boundary that went through our area last night will be heading back this way as a warm front, probably never to make it. But it will help increase the cloud cover in the region on Thursday. But that boundary never makes it and a stronger northwesterly flow brings another Canadian cold front into and across the region Friday, bringing the only chance of rainfall during this 5-day period, in the form of scattered showers. Canadian high pressure builds in to provide the region with dry and pleasant summer weather for the weekend…

TODAY: Mostly sunny. Highs 78-85. Dew point falling below 60. Wind NW 5-15 MPH with a few higher gusts through mid morning, then variable up to 10 MPH with coastal sea breezes.

TONIGHT: Partly cloudy. Lows 60-67. Dew point below 60. Wind variable up to 10 MPH.

THURSDAY: Partly sunny. Highs 78-85, coolest coast. Dew point under 60. Wind variable up to 10 MPH with coastal sea breezes.

THURSDAY NIGHT: Mostly cloudy. Lows 60-67. Dew point under 60. Wind variable up to 10 MPH.

FRIDAY: Variably cloudy. Isolated to scattered showers. Highs 76-83. Dew point over 60. Wind variable 5-15 MPH.

FRIDAY NIGHT: Mostly cloudy with a chance of showers early, then clearing. Lows 57-64. Dew point falling to near 50. Wind NW 5-15 MPH.

SATURDAY: Sun and passing clouds. Highs 77-84. Dew point 50s. Wind NW 5-15 MPH.

SATURDAY NIGHT: Mostly clear. Lows 55-62. Dew point under 50. Wind N under 10 MPH.

SUNDAY: Mostly sunny. Highs 77-84, coolest coast. Dew point near 50. Wind N shifting to E up to 10 MPH.

DAYS 6-10 (JULY 11-15)

High pressure will be the main player in our weather at first, and as it shifts to the south of the region the trend will be for weather weather with an increase in temperature and humidity. A frontal boundary moves into the region mid into late period with a shower and thunderstorm threat.

DAYS 11-15 (JULY 16-20)

High pressure will be in control much of the time. Originating from Canada it brings mild/dry weather at first before sinking to the south and allowing increased warmth and humidity again.

DAYS 1-5 (JULY 5-9)

We’re beyond the big holiday weekend now, which was quite nice for the most part after just some interruption from showers / storms on Saturday. Going through the remainder of this week, we have a couple rounds of unsettled weather to contend with. The first, later today and tonight as a low pressure disturbance crosses the region in a northwesterly air flow. First, the warm front from the system will approach and move through this afternoon with a threat of a little bit of light rainfall, but much of this struggles to make it to the ground as it battles the dry air in place. Moisture spikes this evening ahead of a cold front, which offers a better chance of showers and possible thunderstorms as it moves through the region from northwest to southeast late evening to early overnight hours, basically a couple hours either side of midnight based on current expected timing. Behind this system, high pressure brings nice weather for Wednesday. However, this time it’s only a one-day stand for the great weather, because we’ll already see clouds moving back in Thursday ahead of that frontal boundary trying to lift back as a warm front. That boundary may struggle to get all the way through the region, and will be a general pathway for a wave of low pressure to move across our region later Thursday night and Friday with showery weather. The rainfall and temperature details are a little fuzzy for Friday and are dependent on the exact position of the frontal boundary and track of low pressure – so some fine-tuning will be necessary. Canadian high pressure is expected to arrive just in time for the weekend on Saturday with more great weather – low humidity and pleasant temps!

TODAY: Partly sunny morning. Mostly cloudy with a chance of light rain, favoring southern NH and northern MA, this afternoon. Highs 78-85, cooler South Coast. Dew point rising toward 60. Wind S 5-15 MPH.

TONIGHT: Variably cloudy early to mid evening with isolated showers. Mostly cloudy late evening to early overnight with showers likely and a chance of thunderstorms. Breaking clouds but areas of fog toward dawn. Lows 60-67. Dew point lower to middle 60s. Wind variable to SW 5-15 MPH shifting to NW toward dawn.

WEDNESDAY: Mostly sunny. Highs 77-84. Dew point falling below 60. Wind NW 5-15 MPH early then variable up to 10 MPH with coastal sea breezes.

WEDNESDAY NIGHT: Partly cloudy. Lows 60-67. Dew point below 60. Wind variable up to 10 MPH.

THURSDAY: Partly sunny. Highs 78-85, coolest coast. Dew point under 60. Wind variable up to 10 MPH with coastal sea breezes.

THURSDAY NIGHT: Mostly cloudy. Lows 60-67. Dew point under 60. Wind variable up to 10 MPH.

FRIDAY: Variably cloudy. Chance of showers, possibly thunderstorms. Highs 76-83. Dew point over 60. Wind variable 5-15 MPH.

FRIDAY NIGHT: Mostly cloudy with a chance of showers early, then clearing. Lows 57-64. Dew point falling to near 50. Wind NW 5-15 MPH.

DAYS 6-10 (JULY 10-14)

High pressure is expected to bring fair, dry weather to finish the weekend on July 10. High pressure shifts to the south and a boundary sits north of to near the region with higher humidity and an increased chance of showers and thunderstorms later in the period.

DAYS 11-15 (JULY 15-19)

High pressure in control most of this period. Near to above normal temperatures, mostly dry weather with continued limited rain chances.

DAYS 1-5 (JULY 4-8)

Happy Independence Day! This will be a top 10 summer day across our area with high pressure in control, sunshine and a few decorative high cloud patches, and maybe a few fair-weather clouds popping up during the day. The air will be dry and the temperature generally in the range that is comfortable for anyone outside for both daytime (remember sun screen!) and evening (remember insect repellent!) activities. The overall weather pattern we’ve entered the summer in remains with us though, and we’ll be seeing a disturbance move through out region from northwest to southeast Tuesday, bringing more cloudiness and some unsettled weather. However we may get through a lot of the day without rainfall threatening – just having some showers pass by mostly to the north in the morning, with a warm front, and a shower/thunderstorm threat holding off until the nighttime hours, with a cold front. This system exits early Wednesday, and high pressure builds in with fair weather for midweek, then slides away later in the week as the next disturbance approaches with unsettled weather returning for Friday.

TODAY (INDEPENDENCE DAY): Mostly sunny. Highs 81-88, cooler coastal areas. Dew point 50s. Wind NW up to 10 MPH but some coastal sea breezes midday-afternoon.

TUESDAY: Mostly cloudy with a chance of showers favoring northern MA and southern NH in the morning. Partly sunny afternoon. Highs 78-85, cooler South Coast. Dew point rising to lower to middle 60s. Wind S 5-15 MPH.

TUESDAY NIGHT: Mostly cloudy with a chance of showers/thunderstorms. Patchy fog. Lows 60-67. Dew point lower 60s. Wind variable up to 10 MPH.

WEDNESDAY: Partly sunny. Highs 78-85, coolest coast. Dew point near 60. Wind variable up to 10 MPH with coastal sea breezes.

WEDNESDAY NIGHT: Partly cloudy. Lows 60-67. Dew point below 60. Wind variable up to 10 MPH.

THURSDAY: Partly sunny. Highs 78-85, coolest coast. Dew point under 60. Wind variable up to 10 MPH with coastal sea breezes.

DAYS 1-5 (JULY 3-7)

Short and sweet update here. Cold front has pushed offshore. Dew points have been lowering from northwest to southeast and this trend will continue today. We start with an extensive high cloud shield over the region but this will gradually clear away and the limited sun will become brighter by midday onward with just a few fair-weather cumulus popping up to decorate the sky, so it does turn out to be a wonderful Sunday, and this great weather will continue through the Monday Independence Day holiday too. Look for some coastal sea breezes though as we’ll have fairly light wind. Our only unsettled weather day in this 5-day forecast is Tuesday, which will feature clouds and a shower chance as a disturbance moves in from the northwest. This is much more quickly and of shorter-duration than medium range guidance had this just a few days ago, so here’s another example about what us meteorologists say about trusting guidance too much too far out and using it wisely. High pressure returns by midweek with fair weather and pleasant air.

TODAY: Limited sun morning. Brighter sun and a few clouds afternoon. Highs 80-87. Dew point 50s Boston north and west, 60s elsewhere, with a lowering trend. Wind W 5-15 MPH.

TONIGHT: Mostly clear. Lows 60-67. Dew point below 60. Wind W up to 10 MPH.

MONDAY (INDEPENDENCE DAY): Mostly sunny. Highs 81-88, cooler some coastal areas. Dew point below 60. Wind NW up to 10 MPH but some coastal sea breezes possible.

MONDAY NIGHT: Mostly clear to partly cloudy. Lows 58-65. Dew point lower 50s. Wind NW under 10 MPH.

TUESDAY: Mostly cloudy. Showers likely and a chance of thunderstorms, especially afternoon. Highs 76-83. Dew point rising into 60s. Wind S 5-15 MPH.

TUESDAY NIGHT: Mostly cloudy with a chance of showers/thunderstorms evening. Partly cloudy overnight. Patchy fog. Lows 60-67. Dew point lower 60s. Wind variable up to 10 MPH.

WEDNESDAY: Partly sunny. Highs 78-85, coolest coast. Dew point near 60. Wind variable up to 10 MPH with coastal sea breezes.

WEDNESDAY NIGHT: Partly cloudy. Lows 60-67. Dew point below 60. Wind variable up to 10 MPH.

THURSDAY: Partly sunny. Highs 78-85, coolest coast. Dew point under 60. Wind variable up to 10 MPH with coastal sea breezes.

DAYS 6-10 (JULY 8-12)

Limited rainfall chances to probably one disturbance passing by mid period. Low humidity and near normal temperatures to start the period, possibly replaced by warmer and more humid weather later in the period.

DAYS 11-15 (JULY 13-17)

High pressure in control most of this period. Near to above normal temperatures, mostly dry weather with continued limited rain chances.

DAYS 1-5 (JULY 2-6)

An unsettled Saturday. That’s what we have. But we’ll have our “quiet times” around the region today too. A batch of showers and thunderstorms rolled across New England, thunder focused more toward the South Coast, in the pre-dawn to shortly-after-dawn time frame, and is heading offshore as I write this update. We’ll be vulnerable to showers and thunderstorms at any time here in the WHW today until this evening, but the tendency will be for the threat to diminish from northwest to southeast late-day / evening as a cold front slides through the region. If you have outdoor plans today, keep a very close eye on the weather. Any storms that do occur can be strong to severe. When it’s done, most people won’t see severe weather at all, but those that do can get a pretty solid hit. It’s very important to keep this in mind in any case, but even more so with this being a holiday weekend and many outdoor things going on. After today’s “headache” though, it’s clear sailing for Sunday and Independence Day Monday, as high pressure takes over and sends a refreshing Canadian air mass into our area. Tuesday looks more humid and unsettled as a disturbance moves into the region on a northwesterly air flow aloft, but this should be departing by Wednesday with some improvement in the weather.

TODAY: Mostly cloudy to partly sunny. Showers and thunderstorms possible at any time, with any thunderstorms potentially strong to locally severe. Highs 79-86. Dew point upper 60s to near 70. Wind SW 5-15 MPH, possible higher gusts.

TONIGHT: Variably cloudy with isolated showers/thunderstorms evening. Clearing overnight. Lows 61-68. Dew point falling to 50s north of I-90 but hanging in the lower 60s to the south. Wind W 5-15 MPH.

SUNDAY: Lingering clouds South Coast early, otherwise mostly sunny. Highs 80-87. Dew point middle to upper 50s except lower 60s South Coast early. Wind NW 5-15 MPH.

SUNDAY NIGHT: Clear. Lows 60-67. Dew point below 60. Wind W up to 10 MPH.

MONDAY (INDEPENDENCE DAY): Sun/cloud mix. Highs 81-88, cooler some coastal areas. Dew point below 60. Wind W up to 10 MPH but some coastal sea breezes possible.

MONDAY NIGHT: Mostly clear to partly cloudy. Lows 58-65. Dew point lower 50s. Wind W under 10 MPH.

TUESDAY: Mostly cloudy. Showers likely and a chance of thunderstorms, especially afternoon. Highs 76-83. Dew point rising into 60s. Wind S 5-15 MPH.

TUESDAY NIGHT: Mostly cloudy with a chance of showers/thunderstorms evening. Partly cloudy overnight. Patchy fog. Lows 60-67. Dew point lower 60s. Wind variable up to 10 MPH.

WEDNESDAY: Partly sunny. Highs 78-85, coolest coast. Dew point near 60. Wind variable up to 10 MPH with coastal sea breezes.

DAYS 6-10 (JULY 7-11)

Two disturbances should move through the region with a west to northwest flow during this period bringing opportunities for showers/thunderstorms for relatively brief periods of time. Temperatures ups and downs with air mass changes but no extreme heat or cool anticipated during this time frame.

DAYS 11-15 (JULY 12-16)

Weaker westerly flow and more high pressure to the south should allow for warmth and somewhat higher humidity to be the rule but with limited shower and thunderstorm opportunities.

C-19 Chat Post – 7-2-2022

DAYS 1-5 (JULY 1-5)

On this first day of July, many people begin a multi-day holiday weekend, so basically we treat this 5-day period like it’s one extended weekend, and weather-wise, it’s going to be a pretty good one as far as summertime weekends go. No, it’s not going to be perfect. We have some heat in the forecast, some thunderstorms in the forecast, and some wonderfully warm and dry weather as well. High pressure slides offshore today and in comes the heat. But the humidity is not going to jump up right away. That’s actually going to spike later today, mainly this evening, tonight, and into Saturday. On the heading edge of this “dew point boundary” we may see an isolated thunderstorm or two fire up somewhere in the WHW forecast area this afternoon, but I would not cancel any plans over it. Just keep an eye out for building clouds and if you hear thunder, be ready to move to a place of safety while any storm passes by your area. The most likely time for this to happen is mid to late afternoon. Tonight, the storm threat vanishes in the evening but returns overnight as a disturbance moves through the region. Another disturbance brings the chance of a couple morning showers and thunderstorms Saturday as we sit in the soupy air. And finally a cold front will slice across the region from northwest to southeast Saturday midday and afternoon, finally exiting via the South Coast during the evening hours. This front will trigger the best chance of thunderstorms, in terms of coverage and intensity, but it will likely take the place of one line or a couple line segments. Any of these storms can become strong to severe, so anybody with outdoor plans should be very aware of the weather Saturday. From Saturday evening on through Sunday as well as Independence Day Monday, it’s “clear sailing” with a Canadian air mass arriving and providing great weather. When we get to Tuesday, we’ll be eyeing the approach of a disturbance from the northwest which at least brings clouds, and perhaps a shower and thunderstorm chance. Some fine-tuning is needed for this, as quick-moving disturbances are hard to time beyond a couple days in advance.

TODAY: Sun/cloud mix. Isolated thunderstorms mid to late afternoon. Highs 88-95, cooler South Coast. Dew point ranging from middle 50s north and west to middle 60s South Coast through early afternoon, rising to middle to upper 60s all areas later. Wind SW 5-15 MPH, higher gusts by late in the day.

TONIGHT: Partly cloudy evening. Variably cloudy overnight with isolated to scattered showers and thunderstorms possible. Lows 67-74. Dew point upper 60s. Wind SW 5-15 MPH.

SATURDAY: Variably cloudy. A shower or thunderstorm possible early, then a passing shower or thunderstorm during the afternoon and early evening from west northwest to east southeast across the region, with any thunderstorms potentially strong to locally severe. Highs 85-92, cooler South Coast. Dew point rising to upper 60s to around 70 through early afternoon, then falling slightly especially in northwestern areas by late day. Wind SW 10-20 MPH except variable with potential strong gusts near storms, shifting to W from northwest to southeast later in the day.

SATURDAY NIGHT: Variably cloudy. Evening showers and thunderstorms possible, mainly South Coast. Areas of fog especially South Coast. Lows 62-69. Dew point falling to upper 50s north of I-90 but staying in 60s to the south. Wind W 5-15 MPH.

SUNDAY: Lingering clouds South Coast early, otherwise mostly sunny. Highs 80-87. Dew point middle to upper 50s except lower 60s South Coast early. Wind NW 5-15 MPH.

SUNDAY NIGHT: Clear. Lows 60-67. Dew point below 60. Wind W up to 10 MPH.

MONDAY (INDEPENDENCE DAY): Sun/cloud mix. Highs 81-88, cooler some coastal areas. Wind W up to 10 MPH but some coastal sea breezes possible.

MONDAY NIGHT: Mostly clear to partly cloudy. Lows 58-65. Wind W under 10 MPH.

TUESDAY: Increasing clouds. A shower or thunderstorm possible. Highs 76-83, coolest coast. Wind variable up to 10 MPH with coastal sea breezes.

DAYS 6-10 (JULY 6-10)

Two disturbances should move through the region with a west to northwest flow during this period bringing opportunities for showers/thunderstorms for relatively brief periods of time, and some variable temperatures but not straying that far from normal.

DAYS 11-15 (JULY 11-15)

Weaker westerly flow and more high pressure to the south should allow for warmth and somewhat higher humidity to be the rule but with limited shower and thunderstorm opportunities.
